All living things must get and use
energy. What is known as the chemical
processes that make energy needed to
maintain life?
A. metabolism
B. homeostasis
C. stimulus
Answer:
A. metabolism
Explanation:
Metabolism is the bodily process used to convert food into energy.
To survive, the body must use energy. Energy is important to perform daily tasks as big as moving and as small as undergoing mitosis. All of this energy comes from the food we eat.
Metabolism is a complex process that works to break down the calories within food and convert them into energy we can use.
The ultimate goal of energy metabolism is to transform energy-yielding nutrients into what compound?.
The ultimate goal of energy metabolism is produce the compound called ATP.
What is ATP?This is known as Adenosine triphosphate and it is referred to as the energy currency of the cell.
It is formed during energy metabolism from energy-yielding nutrients such as carbohydrates etc which was why it was chosen as the most appropriate choice.

An enzyme that copies dna to make a molecule of rna is:.
Answer: An enzyme that copies DNA to make a molecule of RNA is RNA polymerase.
Answer:
RNA polymerase
Explanation:
RNA polymerase has many important roles inside of an organism and is a very complex enzyme. One of the most common roles "RNA polymerases" has, is that it is able to copy DNA to then make an RNA molecule. Another common role the RNA polymerase has, is that it helps maintain the organism's metabolism. Which means the enzyme itself helps the chemical processes within an organism be completed in order to keep that organism from dying.

Compare and contrast the roles and importance of photosynthesis and cellular respiration in the biosphere.
Specifically, you are going to discuss where these processes occur in the cell, what organisms have these
processes, what are the
reactants/products of each process, what is the role of each process, and explain in
each one in detail.
Your discussion must be 150+ words. Use the following words in your response: anabolic/catabolic process,
water, oxygen, glucose, sunlight, carbon dioxide, chloroplasts, mitochondria, photosynthesis, cellular
respiration, and ATP.
Answer:
Cellular Respiration Photosynthesis
The entire process occurs in Mitochondria. The entire process occurs in Chloroplasts.
Glucose and oxygen are the reactants of this process. Carbon dioxide, water and light energy are the reactants of this process.
Explanation:
Cellular respiration takes place in the mitochondria of cells. While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. Plants perform both photosynthesis and respiration, while animals can only perform respiration.

Which is a cause of drought?
A.High precipitation levels
B.low water demand
C.low precipitation levels
D.high water demand
Drought is the time period where is marked by dry conditions which is caused by the low precipitation levels. Thus, the correct option is C.
What is Drought?Drought is a prolonged dry period in the natural climatic cycle in an environment that can occur any geographic location in the world. It is a slow-onset disaster which is characterized by the lack of precipitation, resulting in a water shortage condition. Drought may cause a serious impact on the overall health, agriculture, economies, energy and the environment of an area.
Drought is mainly caused by a lack of rainfall, which causes serious water shortage. This condition can be fatal. Unlike the other extreme weather events that are more sudden, like that of earthquakes or hurricanes, droughts can happen gradually.
Therefore, the correct option is C.

Explanation:
In guinea pigs, the allele for black fur (B) is dominant over the allele for white fur (b). A black male guinea pig is mated to a white female guinea pig. The offspring were 7 black and 6 white guinea pigs. What are the genotypes of the parents?
Answer:
Male: Bb
Female: bb
Explanation:
1. I made punnet squares to test each genotype pairs:
BB (black male) x bb (white female)
Bb (black male) x bb (white female)
** B is dominant over b so if Bb, black will be expressed
3. I calculated the percentage of each phenotype to see if it matched the the number of white and black guinea pigs produced. I found that Bb x bb had 50% chance for white guinea pigs and 50% chance for black guinea pigs, which is about the same in the scenario above (7 black, 6 white).
4. I infered that the male black guinea pig's genotype is Bb and the female white guinea pig's genotype is bb.
