Which chemical compund is formed during photosynthesis ?

Answers

Answer: carbon dioxide / CO2

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose

Which of the following is true about adaptation?

I. It is random.
II. It results from genetic mutations.
III. It only affects an individual in a population.

I, II, and III
I and II
II and III
I only

Answers

Answer: I and II

Explanation: so basically,  when adaptation occurs, it usually happens over a long period of time due to climate, predators, etc. because of these adversities,  Genetic mutations occur, helping that animal and its species as a whole survive, which checks number 2. number one is also correct because adaptation can not be predicted. it happens randomly at some point in time. 3 is incorrect because multiple offspring in a species could have adaptations that provide more of an advantage.

Explain why cellular respiration releases energy as an overall chemical reaction

Answers

Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).

Answer:

In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step. The goal of cellular respiration is to capture this energy in the form of ATP

In other words:

Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

B.
It is a class, because not all of the descendants of the ancestral species are included.
C.
It is a clade, because the cladogram does not show that the group is descended from a common ancestor.
D.
It is a class, because the cladogram does not show that the group is descended from a common ancestor.

Answers

Although we do not have access to the diagram to provide a complete answer, we can confirm that a clade is when all members of the group being highlighted belong to a common ancestor.

What is a clade?

As stated, this is when the members of a depicted group belong to the same ancestor. It would be a clade if the organisms present are all descendants of a common ancestor, such as the class Aves or birds.

Therefore, we can confirm that a clade is when all members of the group being highlighted belong to a common ancestor.
