Answer:
Oxygen
Explanation:
The formula for cellular respiration is oxygen + glucose -> water, carbon dioxide, energy. You can already cross out A and D because they aren't in the formula, so you have two left, water and oxygen. The reason why it is oxygen and not water is because without oxygen you can't even have water. also, I just got this right on my test :-)
The answer is apical meristem.
<span>An apical meristem is a meristem tissue found at the tips of branches. When the apical meristem is active, a tree grows in height. By growing in height, leaves will be elevated and that way exposed to the sunlight so the process of photosynthesis can take place.</span>
The modern bread wheat which is the product of multiple instances of hybridization of wheat species in the question is an example of : Cell division and self fertilization
<h3>Similariity between modern wheat and wheat found in middle eastern farms </h3>
Modern Wheat used for bread is similar to wheat found in the middle eastern farms 10,000 years ago in that they underwent several hybridization process of wheat species before been used as modern bread wheat. This process is an example of cell division and self fertilization.
Hence we can conclude The modern bread wheat which is the product of multiple instances of hybridization of wheat species in the question is an example of : Cell division and self fertilization

Biologists are the people who study and research about most of the things that are related to living things, including plants, animals, bacteria etc.
Example of topics they study include "ecology", like how different living organisms relate and interact with each other, or "cell biology", with small topics like how protein synthesis works or what is DNA or RNA.
Area of scientific studies that usually fall outside biology includes "astronomy" the study of space, or" chemical bondings", like how does elements react with each other.
