Answer: B. Afferent; to; from
Afferent pathways include all the pathways that bring information to the brain and spinal cord from the effector muscles and glands.
Explanation:
Afferent signals come from outside stimuli and tell your brain what they are sensing, such as temperature.
Efferent pathways carries signals away from the central nervous system which includes the brain and spinal cords. There are signals that your brain sends to tell your body to do something, like blinking.
Anaerobic respiration happens in muscle cells and yeast cells.
The equation describes anaerobic respiration in muscle cells.
glucose ---> lactic acid
How can you tell from the equation that this process is anaerobic?
would the answer just be no co2 is produced?
Answer:
Am I think Co 2 will not be released but rather Glucose will be released
Explanation:
This is because
C6H12O6>2C5H5OH+2Co2 + Energy
there fore glucose is produced
From the equation "glucose → lactic acid," we can infer that the process is anaerobic. One way to determine this is by the absence of carbon dioxide (CO2) in the equation.
Glucose is entirely oxidized to create carbon dioxide, water, and energy during aerobic respiration, which takes place in the presence of oxygen.
Yet, in anaerobic respiration, the lack of oxygen causes an incomplete breakdown of glucose, producing additional byproducts such lactic acid as a result.
Muscle cells have the ability to transition to anaerobic respiration in order to satisfy their energy needs when there is insufficient oxygen.
Muscle cells have the ability to engage in anaerobic respiration, which produces ATP (adenosine triphosphate), the cellular energy currency, by partly metabolizing glucose, during hard exercise or when oxygen supply is constrained.
During anaerobic respiration, lactic acid builds up in muscle cells, which can lead to exhaustion and pain.

Select the statements that accurately describe endocytosis.
a. The cell forms proteins that move substances into the cell against a concentration gradient.
b. The cell selectively filters small nutrients through specialized membrane pores.
c. The cell membrane pinches off to form an extracellular vesicle joined to the cell by filaments.
d. The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it.
e. The cell expends energy to transport materials into the cytosol.
Answer:
The correct answer is:
The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it. (d.)
Explanation:
Endocytosis is a type of active transport, where particles such as (large molecules, parts of cells, and even whole cells) are moved into cells.
The various types of endocytosis has a common feature of:
1. invagination of plasma membrane forming pockets around the target particle.
2. the pocket pinches off from original plasma membrane
3. forming a new intracellular vesicle containing the target particle.
The different types of endocytosis includes
a. pinocytosis (cell drinking): takes in extracellular fluids
b. phagocytosis (cell eating): large solid particles are taken in by cells
c. receptor-mediated endocytosis: here, receptor proteins on the cells surface, binds to complementary proteins on the surface of the target particles before endocytosis occurs.
Identify the remaining processes and components of the carbon cycle. organisms release CO2 atmospheric CO2 plants use CO2 combustion fossil fuels form
Answer:
Carbon dioxide (CO2) is an important component in atmosphere and Carbon cycles allows movement of carbon dioxide from the atmosphere into living things and from living things to atmosphere again.
There are four main processes included in carbon cycle that is photosynthesis, decomposition, respiration and combustion.
In respiration, living organism such as animals and humans intake oxygen and releases CO2 in atmosphere.
In the process of photosynthesis, plants take CO2 from atmosphere and convert it into oxygen (O2) in the presence of sunlight and water.
In Decompoition, the bacteria present in soil decomposes dead matter by breaking down into simpler organic or inorganic matter such as water, carbon dioxide, and mineral salt. The nutrient cycle then recycle the carbon dioxide and send back to teh atmosphere.
In combustion, the burning of fossil fuel in cars and industries releases carbon dioxide back into the atmosphere.
So, the components of carbon cycel include atmosphere, terrestial biosphere, ocean ( dissolved inorganic carbon), and sediments ( fossil fuels).

As a conservationist, what are your top three concerns regarding the hydroelectric dam and the biodiversity of the region?
Answer:
I’m concerned about how the dam will affect the water flow in the river, which can affect the behaviors of fish. I’m also concerned that some fish and aquatic animals might get sucked into the dam. Finally, I worry that the dam could malfunction and cause flooding, which could damage the ecosystem.
Explanation:
Top three concerns regarding the hydroelectric dam and the biodiversity of the region
Hydropower can also cause environmental and social problems. Reservoirs drastically change the landscape and rivers they are built on. Dams and reservoirs can reduce river flows, raise water temperature, degrade water quality and cause sediment to build up. This has negative impacts on fish, birds and other wildlife.
How do hydroelectric power plants affect the environment?Hydroelectric plants alter the natural habitats of freshwater species in the areas they are located. It changes the concentration of nutrients, water temperature, and the river's flow. Downstream river flow suffers a loss of water and silt loads, reducing water quality.

Given the following evidence; which does not support the theory of Continental Drift? A) climate
B) fossils of plants and animals
C) magnetic strips in the ocean floor
D) land features match up (like mountains) on different continents
The theory of Continental Drift does not shows evidence about climate. Thus option A is correct.
What is continental drift?Continental drift is defined as the idea that the positions of Earth's continents have changed over geologic time, giving the impression that they have "drifted" across the ocean floor.
It can also be defined as the continents moving horizontally at a huge scale in relation to one another and the ocean basins throughout the course of one or more geologic epochs.
The theory of plate tectonics, which integrates this idea, had this idea as a key antecedent.
The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift.
Thus, the theory of Continental Drift does not shows evidence about climate. Thus option A is correct.

A large population of fish live in a lake. The color of their scales is determined by two different alleles of the autosomal S gene, S1 and S2. Homozygous S1S1 fish have yellow scales, S2S2 homozygotes have blue scales, and S1S2 heterozygotes are green. Scientists caught 100 fish at random and recorded their color. Among those 100 fish were 30 yellow, 50 blue, and 20 green ones. After the original sample was analyzed, an asteroid landed in the lake and killed all the fish that happened to be in one particular location. When 100 fish were sampled again, 15 were yellow, 75 were blue, and 10 were green. Was the fish population in Hardy-Weinberg equilibirim (HWE) before the asteroid hit? In an ideal population, how many generations would it take to establish HWE after the asteroid hit?
Answer:
Yes it was
two generations
Explanation:
H0: population is in Hardy-Weinberg equilibrium
Ha: population is not in Hardy-Weinberg equilibrium
P(S1) = (2×obs(S1S1) + obs(S1S2))/(2×fish(S1S1)+2×fish(S1S2) +2×fish(S2S2) )
P(S1)= (60+50)/(60+100+40)
P(S1)=0.55
P(S2)= 1-P(S1)
P(S2)= 0.45
Exp(S1S1)= 0.55×0.55×100=30.25
Exp(S1S2)= 2×0.45×0.55×100=49.5
Exp(S2S2)= 0.45×0.45×100=20.25
x²=∑ (Observed-Expected)²/ Expected
= (30-30.25)²/30.25 + (50-49.5)²/49.5+ (20-20.25)²/20.25
= 0.010203
The value at 5% significance level and degree of freedom 1 from table is 3.84. Since x² value is less than value we accept null hypothesis
It takes two generations to achieve Hardy-Weinberg equilibrium if conditions of Hardy-Weinberg are met.

Explanation:
The water cycle is a cycle, meaning it happens over and over again. Water isn't stored, created, or removed, it is moved around and it goes through different processes. For example, some stages of the water cycle are evaporation, condensation, precipitation, infiltration and run off.
Therefore choice C: the continuous movement of water under on or above the earth’s surface, is correct.
Explain how changes in Earth's systems affect the growth of life on earth
Answer:
hope it is help for you please mark brinlist
Answer:
The topic we were given is to explain how changes in Earth’s systems affect the growth of life on Earth. We will talk about three main things that are a part of this statement which will be; how life affects the climate system, how species can survive, and how do we know about this.
In our introduction we talked about how life affects the climate system. In very short terms, we can conclude that life affects the composition of the atmosphere. We can also conclude that it affects the climate as well because if we apply what we learned in the labs about how different materials absorb heat at different rates then we will see that when you have different life forms that are taking in and releasing gases such as carbon dioxide, methane and oxygen, that they too even have different rates at which they do it. Which backs up the point that it changes the composition of things. So when we have climate changes, not only are the species, but also our ecosystems are. They respond to these scenarios by adapting, migrating or even reducing their own population. Some examples in our own lives would be droughts, heat increasing, and even insect outbreaks. Which all link to climate changes, and even wildfires that occur. Some concerns are that we could have declining water supplies, health impacts in cities due to heat, reduced agricultural yields, and finally erosion and flooding in coastal areas are also very big concerns for us.
How can our species even survive? You may ask,well I will tell you how. Three simple things: move, die, adapt. It's sad to think of what we could be doing to our own ecosystems and animals. The thing is that as time goes on and the more climate changes there may not even be much left. Most animals will either adapt to the climate or move higher trying to escape the hotter weather. Scientists have been making assumptions that maybe it's changing too fast for them to do anything. Because the truth is that why would you want to die voluntarily. I can see why with older animals, but why with younger ones? They could want to run, but the thing is that they don't have a choice. Extinction of living things is one common fear. One day we could all go poof with any word being said, and that should be frightening to people. Adaptation could be the only way we brave through it.
The other part of this is how do we even know about climate change exactly? Over the years we have had many physical and biological changes that are confirming our theory about climate change. The retreat of glaciers, the melting of them and the ice is one big give away as well. Also the intensification of rainfall events, changing in the timing of the plants that are leafing out, range of some species that are shifting, and finally the arrival of migrant birds in springs. We also can see that human activity is also a reason for it changing as well as other things. There is evidence that we can not deny or ignore.
In conclusion, how life affects the climate system, how species can survive, and how we know about this, all play apart in the big story called climate change. It bears the truth that one day will not be pretty or just a concept, it will be utter reality. Until then there is another tomorrow, another week, another month and another year. See you on the flip side of things! Pure truth will one day be exposed, so will the mind of people and things.

Which feature contains genetic material and is present in a eukaryotic cell but not in a prokaryotic cell?
Which two features are present in a plant cell but not in an animal cell? ************someone HELP PLEASE***********
Answer:
A DNA is contained in the NUCLEUS of a eukaryotic cell not a prokaryotic cell. Your awnser is " nucleus"
Explanation:
The feature that contains genetic material and is present in a eukaryotic cell but not in a prokaryotic cell is the nucleus. The two features that are present in a plant cell but not in an animal cell are the cell wall and chloroplasts.
1. Eukaryotic cells have a membrane-bound organelle called the nucleus that contains the DNA of the cell. It is in charge of conserving and safeguarding the genetic material, including the chromosomes that contain the genes that govern the properties and operations of the cell.
On the other hand, prokaryotic cells are devoid of a genuine nucleus. The cytoplasm of these cells contains their genetic material, which is normally one circular DNA molecule.
2. Cell Wall: The cell membrane of plant cells is enclosed by a strong cell wall. The plant cell is protected and supported structurally by the cell wall. Together with other polysaccharides, proteins, and cellulose, a complex carbohydrate, it essentially consists of these elements. Animal cells lack a cell wall and are supported instead by extracellular matrix and other structural elements.
Chloroplasts: The chloroplasts found in plant cells are in charge of photosynthesis. Specialized organelles called chloroplasts house the pigment chlorophyll as well as other pigments that are used to absorb light energy.
They do this by converting light energy into chemical energy, releasing oxygen as a byproduct and creating glucose. As animal cells lack chloroplasts, they are unable to perform photosynthesis.

You observe a population of Island Sparrows for which the phenotype of crown color varies from yellow to white. You perform two experiments. Experiment 1 shows that this variation in the phenotype affects mating success, so that birds with yellow crown colors have more offspring. Experiment 2 shows that this variation in phenotype is determined fully by the diet of the birds and not genetics. Can crown color evolve via natural selection in this population of Island Sparrows?
Answer:
Yes, the color of the crown evolves by the process of natural selection.
Explanation:
Based on experiment 1 mentioned in the question, it is clear that the sparrows with the yellow crown are demonstrating reproductive success, and based on experiment 2, it is demonstrated that the origination of crown color is solely dependent upon the diet consumed by the sparrows, not on the genes.
The yellow crown sparrows exhibit enhanced skills in locating food, finding food or prey is dependent upon the factors like skills of hunting, vision, the musculature of the body, and other things, and all these are partially or completely determined by genetics. This yellow crown sparrow will further pass on their genes to their offspring, which will further provide them good skills of locating food, and thus, will obtain the diet needed for proper growth. These offspring will further pass on the traits to the future generations, and so on.
On the other hand, the sparrows exhibiting white crown seem to be less efficient in locating their food, and they are also generating fewer offspring that exhibit the same lack of food locating skills like their parents. Due to less tendency of finding food, the sparrows with the white crown will suffer from poor diet and thus, will further generate less offspring, and so on.
Therefore, it is clear that for betterment, the sparrows with the yellow crown will evolve further due to their better skills of locating food, and this gives rise to the phenomenon of natural selection.
