Answer:
a.
Explanation:
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
A person sees a ball and kicks it, in part because of actions of the nervous system. Using the parts of the nervous system listed, describe the path of nerve impulses that cause the person to (1) see the ball and (2) kick the ball.
Answer:
In the case of seeing a ball and kicking it can be expressed in the actions of the nervous system as follows:
Part 1. Eyes see the ball and send signals with the help of sensory neurons that carry this message to the spinal cord.
PArt 2. The spinal cord processes the information and sends an "impulse" of kicking the ball that will transfer to motor neurons that transfer it to the brain and then muscles.
Sensory neurons --> spinal cord --> motor neurons --> brain---->leg muscles
Which scientists do you think had they biggest impact on the discovery of DNA and why
Answer:
He was paving the way for a discovery that would change the world. Scientists James Watson and Francis Crick were famously the first to work out the structure of DNA, and Rosalind Franklin and Maurice Wilkins are often credited for capturing the images of the molecule that made this possible.
Answer:
I believe that James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin made the biggest impact on the discovery of DNA.
Explanation:
At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. Franklin’s images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model. These 4 people worked together and made a significant discovery.

Answer:
abiotic
Explanation:
abiotic - nonliving components of an ecosystem that can affect the living organisms.
Temperature is a nonliving component and it affects the organisms that live within a certain environment.
Therefore the answer is Abiotic
Reasons its not the other answers:
Biotic factors must be living things
Temperature is not a living thing therefore Biotic cannot be the answer
Same with living, temperature is not living therefore the answer cannot be living.
Temperature plays a huge role in an ecosystem therefore it is considered an important component and the answer cannot be unimportant.
Which of the following would MOST LIKELY result in decreasing carbon dioxide levels in a lake?
A) an increase in the amount of precipitation
B) a decrease in competition among producers
C) an increase in the number of fish caught from the lake
D) a decrease in the amount of sedimentation entering the lake
Answer: C: an increase in the number of fish caught from the lake
Explanation:
An increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.
What are the effects of carbon dioxide in a lake?Carbon dioxide can have both direct and indirect effects on a lake's ecosystem. Here are some of the effects:
Acidification: When carbon dioxide dissolves in water, it forms carbonic acid, which can lower the pH of the water.
Oxygen depletion: If carbon dioxide levels are too high, it can lead to oxygen depletion in the water.
Algal blooms: High levels of carbon dioxide can also stimulate the growth of algae in the water. This can result in algal blooms, which can have negative effects on the lake ecosystem, such as oxygen depletion, fish kills, and changes in water clarity.
Thus, an increase in the number of fish caught from the lake would most likely result in decreasing carbon dioxide levels in the lake. Therefore, option C is correct.

Conserving water is important because it keeps water pure and clean while protecting the environment.
On worldwide basis domestic use uses least water.
On the worldwide which uses least water?a. industry: 19 percent of total water is used by industry.
b. agriculture: 70 percent of total water is used by agriculture.
c. hydroelectric power plants: 52 percent of water is used by hydroelectric power plant.
d. domestic use: 11 percent of total water is used by domestic use.

Why is mitosis necessary during the development of a human?
Answer:
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

a. The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize populations around the carrying capacity. b. Density-independent factors have an increasingly greater effect as a population's density increases. c. High densities in a population may cause physiological changes that inhibit reproduction. d. Because of the overlapping nature of population-regulating factors, it is often difficult to precisely determine their cause-and-effect relationships. e. The occurrence of population cycles in some populations may be the result of crowding or lag times in the response to density-dependent factors.
Question:
Which of the following is an incorrect statement about the regulation of populations?
Answer:
b. Density-independent factors have an increasingly greater effect as a population's density increases.
Explanation:
A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.
Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;
I. Density-independent factors.
II. Density-dependent factors.
Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.
Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.

What are the weather conditions in an area of low pressure?
Dry weather
Sunny weather
Cloudy with precipitation
Answer: Cloudy with Precipitation
Explanation: Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

In the carbon cycle, atmospheric carbon dioxide is converted into organic material by which process? a) transpiration b) cellular respiration c) decomposition d) photosynthesis
Answer:
The correct answer is d) photosynthesis
Explanation:
Photosynthesis is the process by which plants transform inorganic matter from their external environment into organic matter that they will use for their growth and development. It basically consists of the production of sugars from C02 (carbon dioxide) in the air, minerals and water with the help of sunlight. In this reaction, oxygen molecules are released and carbohydrates are fixed in the plant. Plants absorb sunlight through a pigment called chlorophyll. Not only can plants fix CO2, so do certain bacteria and green algae. Photosynthesis is conditioned by internal plant factors and external or environmental factors.
Which of the following conclusions is most likely true if a region experiences unusually low daily temperatures for the season?

the average daily value of the GDD will rise
the Tbase value for a particular crop will rise
Answer: D
Explanation: Because if it is going to be cold out every day, the plants aren't gonna grow. So that means the crop rarity will go up, and people would take advantage, and sell them for more of a value.
