What is theory?A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
A theory not only explains known facts as it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn't, the theory is refined or rejected. The longer the central elements of a theory hold the more observations it predicts, the more tests it passes, the more facts it explains the stronger the theory.

Research has suggested that the burning of fossil fuel has had to change in the carbon cycle causing an increase in carbon store in the atmosphere. Determine how much less carbon would need to be realesed by burning fossil fuels in order for the amount of carbon stored in the atmosphere to not increase.
The carbon that would need to be released by burning fossil fuels should be lesser than the generation of oxygen in order for the amount of carbon not to increase.
What are fossil fuels?Fossil fuels (e.g. coal) are different types of fuels obtained from fossils, which release carbon dioxide into the atmosphere when they are burned.
Carbon dioxide (CO2) is a gas that has a greenhouse effect and thus can produce climate warming.
In conclusion, the carbon that would need to be released by burning fossil fuels should be lesser than the generation of oxygen in order for the amount of carbon not to increase.

What shuffles genes and increases genetic variation in gametes during meiosis, when these homologous pairs are paired up ?
Meiosis is referred to as reduction division as it divides the chromosome number in half. Crossing over or recombination is the main reason of shuffled genes and increased genetic variation in gametes in meiotic cell division as the homologous pairs are paired up during prophase.
What is crossing over?Crossing over is referred to as the exchange of genes of DNA between paired homologous chromosomes. It actually occurs during the development of egg and sperm cells i.e., during meiosis.
It is an enzyme-mediated step, in which the exchange of genetic material takes place between non-sister chromatids of homologous chromosomes.
It actually occurs at the pachytene stage of prophase I of meiosis cell division.
Thus, it can be concluded that the crossing over is the main reason of shuffled genes and increased genetic variation.

A. Carbon cycle
B. Water cycle
C. Phosphorus cycle
D. Nitrogen cycle
Answer:
A
Explanation:
A. Carbon cycle
Cellular respiration is the metabolic reaction that occurs in the cells of organisms. Cellular respiration and photosynthesis both add carbon dioxide to the biogeochemical cycle. Thus, option A is correct.
What is a biogeochemical cycle?The biogeochemical cycle is the process that transfers and moves the abiotic chemical factors through the various spheres of the earth. It includes carbon, water, nitrogen, phosphorus cycle, etc.
The process of cellular respiration releases carbon dioxide as the waste gas into the atmosphere that gets consumed by the plants to make energy that gets eaten by the organism that again releases the carbon dioxide. This cycle of carbon goes on from the producer to the consumer in the ecological chain.
Therefore, cellular respiration and photosynthesis contribute to the carbon cycle.

Ddt was widely used as a pesticide for 20 years. Its use was banned after studies showed severe side effects were evident in humans, the environment, and animals as a result of ddt. Which reason best explains why the side effects of ddt were so harmful?.
Answer:
One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.
