Question: A marine biologist is testing the hypothesis that cold water promotes the growth of corals. Which of the following study designs may yield the most conclusive results?
A.) Two study sites with stable differing water temperatures, similar water nutrient profiles, and similar coral communities growing at different depths
B.) Two study sites with fluctuating water temperatures, similar coral communities growing at similar depths, with similar water nutrient profiles
C.) Two study sites with the same temperature profile, different coral communities growing at different depths, with different water nutrient profiles
D.) Two study sites with stable differing water temperatures, similar coral communities growing at similar depths, with similar water nutrient profiles
Answers
The statement that reveals the best study designs and may yield the most conclusive results is as follows:
Two study sites with stable differing water temperatures, similar water nutrient profiles, and similar coral communities growing at different depths.Thus, the correct option for this question is A.
What is Hypothesis?In experimental biology, the hypothesis may be defined as a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon. It is basically an assumption that is made based on some evidence.
According to the context of this question, the hypothesis that best demonstrates the most conclusive results for the above experiment is the stable differing water temperatures, similar water nutrient profiles, and similar coral communities growing at different depths. This is because the depths of the coral may vary with respect to the nutrients available in an aquatic ecosystem.
Therefore, the correct option for this question is A.

Cellular respiration uses one glucose molecule to produce a total of
A. 36 ATPs.
B.38 ATPs.
C. 2 ATPs.
D. 24 ATPs.
Answers
Cellular respiration uses one glucose molecule to produce a total of 38 ATPs (option B).
What is cellular respiration?Cellular respiration is the process by which cells obtain chemical energy by the consumption of oxygen and the release of carbon dioxide.
Cellular respiration occurs in three processes namely;
Glycolysis; this is the cellular degradation of the simple sugar glucose to yield pyruvic acid, and ATP as an energy source. Krebs cycle; this is a series of enzymatic reactions that occurs in all aerobic organisms; it involves the oxidative metabolism of acetyl units, and serves as the main source of cellular energy.Electron transport chain; this is a series of electron transfer that results in the synthesis of large amount of energy.In total, the overall process of cellular respiration results in the formation of 38ATPs.

What are the reactants and products of the light independent reactions?
Answers
Answer:
In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. GA3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants.
The reactants and products of the light-dependent reactions of photosynthesis would be as follows:
Reactant: water, radiant energy, ADP, and NADP+
Products: oxygen gas, ATP, and NADPH
In the light reaction, radiant energy excites the electrons of chlorophyll molecules. The excitation causes the electrons to be knocked off the chlorophyll molecule and the energy of the electrons is used to convert ADP to ATP and NADP+ to NADPH.
The space left by the excited electrons is filled by electrons from water molecules with oxygen from the water molecule being released as a result.

Answers
Explanation:
Biome and the ecosystem are the words that are sometimes applied interchangeably to explain a particular kind of environment.
The biome represents the geographical region that has the same kind of ecological atmosphere, climate and mostly consistent collection of the species and it is made of a large number of ecosystems.
An ecosystem represents a particular element of the biome and a species that nearly interact in it.
Thus the biome is the collection of various types of ecosystems.

When two species are forced to interact in a particular environment, how would
relationships of competition, predation, and mutualism affect the two populations?
Answers
Answer:
Find the explanation below.
Explanation:
When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.
Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.
Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.
Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.

b) How does the thermal energy of solid water change as it melts?
Answers
Answer:
Hi! So solid water would be ice, the particles in ice are very close together which makes it firm and makes it ice. When you put the ice in the microwave, (Microwave has heat so it would be thermal energy!) the particles in the ice mover a tiny bit away from each other which then makes it water. Then, if you boil the water, the particles that are in the water move far away from each other and it turns into steam!
