Answer: A scientific theory cannot be proven correct because there is no way to look into the future and find out if the theory is ever revised. Theories tend to change greatly as new discoveries are made.
Can someone please put this in there own words?
Thank you.
For example, plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action, and sometimes anchoring the cell in a particular location.
Answer:
All cells have plasma membranes. Can molecules enter and leave the cell? Yes. The plasma membrane (also called the cell membrane), is a lipid barrier where molecule organelles live. The golgi ( a cell organelle) helps move the proteins across the plasma membarane. Proteins cannot move through the plasma membrane barrier by themselves because they are not small enough like water.

Population Growth
Project: Analyzing Factors That Affect Carrying Capacity and Biodiversity
In this assignment, you will use simulations to analyze how climate, resources, and habitat size affect
carrying capacity. You will then look at another simulation to analyze the effects of certain factors that
affect biodiversity and populations. Finally, you will write and revise a conclusion on how human activity
affects biodiversity.
Background Information
Population growth is the change in size of a group of organisms of the same species over time. It is
affected by four factors: birth rate, death rate, immigration, and emigration.
Carrying capacity is the maximum total population that an area can support. Carrying capacity limits
population growth and is affected by competition for food, water, shelter, or mates, and threat of
predators, disease, and parasites. Carrying capacity may be affected by one or a combination of these
factors.
Biodiversity is the total variety of organisms that live in the biosphere. Biodiversity is affected by the loss
of habitat, introduction of invasive species, pollution, and/or human activities.
Answer:
Question 1: How does increasing the size of the habitat affect carrying capacity? Explain your answer. Recall the scenarios: 0–15 years, Little land; 15–30 years, Moderate land; 30–45 years, Ample land.
Population numbers self-regulate to some extent since mortality rise when a population exceeds its carrying capacity. Carrying capacity is affected by disease, competition, predator-prey interactions, resource usage, and the number of populations in an ecosystem.
Explanation:
Question 2: How and why did changes in the environmental conditions affect carrying capacity in this scenario? Recall the scenarios: 0–15 years, Harsh winter; 15–30 years, Harsh winter and Cold spring; 30–45 years, Harsh winter, Cold spring, and Hot summer.
The carrying capacity of an environment is also affected by conditions within or adjacent to it. If the environment is adjacent to a human population, for example, this may have an impact on its carrying capacity. Pollution can also have an impact on the carrying capacity of an environment.
Question 3: If there were no other changes in the habitat, would the value under “Larger Than Ample” be correct? Why or why not
Climate change isn't only about global warming. While it is true that temperatures would rise during the summer months, it is also feasible that the winter months would be even colder. As a result of this effect, the winters will be exceptionally cold from year 0 to 15.
Question 4: Suppose there were changes in the habitat that caused this actual value. What might a combination of those changes be
Assume that the climate in a habitat shifts. The amount of precipitation reduces by 20% over time. It will have an impact on the habitat because species that have adapted to drier climates will supplant those that are less suited to the new climate. This best circumstance explains the cause for adaptation, and those that adapted rapidly will replace those who found it difficult to adapt, resulting in the extinction of species as those who can thrive will be able to cope with the rapid shift in the environment. The most fittest survive in the new environment, according to Charle's Darwin thesis.
Question 5: How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer
The graph and table in the supplied question were not provided, nor could they be found anywhere, hence the question was answered based on prior knowledge. Earth's species can adapt to their surroundings, however adaptation in organisms can take thousands to tens of thousands of years. However, for the last 200 years, a consistent rise in temperature has been recorded.
The thermal limits of species residing in the tropics, equator, and poles have already been altered. If the global average temperature rises by one degree Celsius, the number of people on the globe will drop. The population of a species will decline as the number of individuals decreases.
Which part of the blood is responsible for transporting oxygen throughout the body?
Answer:
The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin (Hgb) is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body.
Explanation:
If a sexually reproducing organism was exposed to a harmful substance that caused it to use an asexual process to produce gametes what would be the result?
A-Gametes produced will be able to create offspring that are a better fit to the organism's environment
B-Gametes produced would each be unique increasing the genetic diversity of the organism's population
C-Gametes produced would be identical to the parent cells thereby lowering the genetic diversity of the population
Answer:
A
Explanation:
Gametes (SEX CELLS) have ... A. half the number of chromosomes found in the body cells B. twice the number of chromosomes found in body cells C. two sets of chromosomes
Answer:
A. Half the number of chromosomes found in the body body cells
Explanation:
Somatic (body cells) have 2 sets of chromosomes, while gametes have 1 set of chromosomes. Sperm has one set, and an egg has one set allowing both to fuse to create a new organism.
Answer:
[tex]\boxed {\boxed {\sf A. \ Half \ the \ number \ of \ chromosomes \ found \ in \ the \ body \ cells}}[/tex]
Explanation:
Gametes are sex cells, such as the egg and sperm. They are used in sexual reproduction to produce offspring.
The sex cells are produced during meiosis. The DNA or genetic material is replicated, then the cells divide twice. After this, four haploid cells are produced with half of the genetic material. For example, human body cells have 46 chromosomes but sex cells have 23 chromosomes.
They contain half the genetic material for an important reason. During fertilization, an egg and a sperm fuse. Each one contributes half of the genetic material from the mother or father to create one complete set for the offspring.
Gametes have half the number of chromosomes in body cells and choice A is correct.
Pesticide resistance is increasing, Farmers in the US tost 7% of their crops to pests in the 1940s, over the 1980s and 1990s, the loss
was 13%, despite more pesticides being used. It is estimated that 500-1000 pests have developed a resistance to pesticides. Consider
the diagram showing the evolution of pesticide resistance. Select ALL of the statements that do NOT accurately describe the
mechanisms of pesticide resistance shown in the graphic.
A)Insects that are sensitive to the pesticide all die out after the first
application, leaving only the resistant insects in the population,
B)When insects are exposed to the pesticide, some will develop a mutationmaking it resistant. Only these insects survive in the next generation
C)The first generation has an insect with a gene responsible for resistance toa pesticide. This allows it to survive the pesticide application and reproduce
D)The insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this
trait become more prominent in the population
E)As a population of insects is exposed to a pesticide, those susceptible to
the pesticide will die out of the population, leaving those with a resistance
to survive and reproduce, becoming more common in the population
The insect with the pesticide resistance gene reproduces, these insects are more likely to survive pesticide application hence insects with this trait become more prominent in the population
What is a pesticide?A pesticide refers to a chemical that is used to control the spread of pests in the farm.
The question is incomplete but I will help you the much I can. We know that organisms that have favorable traits live long enough to reproduce and pass on these favorable traits to the next generation. Therefore, the insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this trait become more prominent in the population

How does waste removal in a fetus differ from waste removal after birth?
A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.
B) Fetal waste is removed through the rectum; infant waste is removed through the chorion.
C) Fetal waste is removed through the ductus venosus; infant waste is removed through the rectum.
D) Fetal waste is removed through the large intestine; infant waste is removed through the ductus venosus.
Answer: A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.
Explanation:
A developing fetus is surrounded by chorion which is an outer membrane. The role of the chorion is to protect the embryo and provide nutrition to it in the form of blood supply. It helps in getting rid of waste products from the developing fetus that goes into the mother blood to remove out of her body. In case of infants the rectum is the last part of the digestive tract and it receives the waste in the form of fecal matter from small intestine which is removed out through the rectum.

When rocks and minerals are worn and broken down into small pieces by water, wind, or ice, the resulting particles are called ?
Sand i think? Maybe dust tho if sand isnt an option
Explanation:
The resulting particles are called sediments.
Rocks and minerals are disintegrated by agents of weathering such as water, glacial (ice) and wind. When these agents of weathering act on rock and minerals, they break down into small particles. These small pieces of weathered rocks and minerals is what is called sediments.
Sediments are pieces of weathered materials from rocks and minerals which can be carried by agents of erosion and deposited in another location.
Thus, the resulting particles from the breakdown of rocks and minerals are called sediments.

In griffins, the allele for black feathers (B) is dominant over silver feathers (b) which are recessive. Two black griffins are crossed and have a silver offspring. What is the genotype of the parents?
Answer:
The correct answer is - Bb and Bb.
Explanation:
In this case, there are two traits decided by the black "B" allele that is dominant over "b" which is silver. In this case the cross between two black feather birds and the there would be genotype:
BB and BB or Bb and Bb or Bb and BB
1. In first case, and the third case, there is no or only one allele for the silver trait so the correct answer would be - Bb and Bb
B b
B Bb Bb
b Bb bb
thus, the correct answer is - bb which is silver feather.

Explanation:
There doesn’t seem to be very much water present in the image which would be the cause for the rest of them
Hope this helps
Answer:
Earthquake
Explanation:
First off I wouldn't say landslide because if it was a landslide in more than likely would have cracked the concrete on the floor that the people are standing on and there would be more of a mess than what is show in the picture. Next I wouldn't say tsunami depending on how frequent this disaster was, if it was a tsunami more than likely most of that rubbish would have been soaked with water in other things that were in the water as well and I wouldn't say flood either because once again nothing is soaked with water with in that picture not even the concrete that the people are standing on so I say that the most reasonable answer would be earthquake due to them being know for destroying buildings alot.

Elements of xylem in a vascular bundle are lesser than those of phloem؟
Answer:
No.
Explanation:
No, elements of xylem in a vascular bundle are not lesser than those of phloem because of the division of xylem progenitor cells that increases the xylem concentration in vascular bundle. The vascular cambium forms more xylem tissue than phloem due to more division of the xylem progenitor cells. so in the light of this discussion we can say that xylem is more in concentration than phloem in a vascular bundle.
