What two processes fuel the carbon cycle?

Answers

Answer 1

Answer:

The two processes that fuel the carbon cycle are photosynthesis and cellular respiration.

Photosynthesis is the process by which carbon obtained from carbon dioxide (atmosphere) is fixed into the biomass (glucose or food).

This food or carbon content is then passed to animals through the food chain and to fossil fuels through decomposition.

This food or carbon content is then used by cellular respiration which releases carbon dioxide back into the atmosphere.

In addition, the burning of fossil fuels also releases carbon dioxide back into the atmosphere.

Answer 2

Answer: The two processes that fuel the carbon cycle are photosynthesis and cellular respiration.

Which of the following is a condition that must be met for a population or an allele to be in Hardy-Weinberg equilibrium?A The population in question must be small
B Organisms must be free to migrate into or out of the population
C New mutations must be introduced to the gene pool at a consistent and unfluctuating rate
D Organisms in the population must express no mating preferences

Answers

The answer is D) Organisms in the population must express no mating preferences.

Some of the conditions that must be met for a population or an allele to be in Hardy-Weinberg equilibrium are:

1. The population must be very large - so A) could not be the right answer.
2. There must be no migration and population must be isolated - so B) could not be the right answer.
3. There must be no mutations - so C) could not be the right answer.
4. There must be random mating, which means there are no mating preferences - so, D) is the right answer.

Explanation:

Joe is conducting an experiment to determine which liquid will cause bean plants to grow faster. He watered the plants with equal amounts of liquid and measured their height every other day. The plants are in the same pots with different soils and placed in the same location. Will Joe be able to obtain reliable data to write a supported conclusion?A. Yes, because he is only observing the height of the plant.
B. Yes, because he consistent with watering the plants.
C. No, because he used different soils.
D. No, because he use only one type of plant.

Answers

Yes because he is only observing the height of the plants and he only changes one variable

Answer:

C. No, because he used different soils.

Explanation:

In order to obtain reliable data to support a conclusion during an investigation, you need to control as many variables as possible. Joe put the plants in the same pots and placed them in the same location, and he should have also used the same soil for all of the plants.

How should you test a hypothesis?How should you test a hypothesis?by writing a mathematical equation

by making a single observation

by performing a controlled experiment

by answering a series of questions

Answers

Analyze sample data. Test statistic. When the null hypothesis involves a mean or proportion, use either of the following equations to compute the test statistic. ...P-value. The P-value is the probability of observing a sample statistic as extreme as the test statistic, assuming the null hypotheis is true.

C.) By performing a controlled experiment
