Answer;
C.Identify each bird species by using a dichotomous key.
Explanation;
-A dichotomous key is a tool that is used to determine the identity of items in an ecosystem or a particular habitat, such as trees, birds, wildflowers, mammals, reptiles, rocks, and fish. To study the interactions of different birds , identifying each birds species using a dichotomous key would be an important and appropriate step.

Explanation:
Cell division involves splitting the parent cell into two identical daughter cells
Answer:
The correct answer would be b. because water provides electrons.
During the light reaction of the photosynthesis, the water is photolysed into high energy electrons, hydrogen ions, and oxygen.
The overall reaction can be written as:
2 H₂O + sunlight → 4 H⁺ + 4 e⁻ + O₂
It takes in water-splitting complex associated with photo-system II rooted in the thylakoid membrane of chloroplast.
The oxygen is released as the byproduct of photosynthesis.
The hydrogen ions help in the formation chemiosmotic potential across the thyllakoid membrane which help in the formation of ATP (adenosine triphosphate).
The electrons are used to replace the electrons lost from chlorophyll a of reaction centre associated with photo-system II. The electrons are lost due to the photo-excitation of chlorophyll a.
The electrons lost from chlorophyll a help in the production of ATP and are used to reduce NADP⁺ into NADPH.
The ATP and NADPH are used in light-independent reaction of the photosynthesis to produce glucose or food.
Answer: hypothesis, prediction, design experiment, carry out experiment, etc
Explanation:If the question is supposed to be, is there a connection between atmospheric oxygen level and photosynthesis, then the next step would be to frame the hypothesis, which could be, for example,
“photosynthesis requires oxygen”, and a prediction such as,,
in a closed system, photosynthesis will reduce the oxygen level, or even photosynthesis does not proceed without oxygen.
and a format to test the hypothesis (design an experiment)
perform the experiment
collect data
analyse data
(of course, in this case, the data will support the null hypothesis).
