A way scientist answer questions and solve problems
Answer:
A. Photosynthesis
Explanation:
Photosynthesis is a process in plants produce food materials by absorbing carbondioxide from the atmosphere which decreases the concentration of carbondioxide in the atmosphere. In photosynthesis reaction, plant take water from the soil and carbondioxide from the atmosphere in the presence of sunlight produces glucose and oxygen. Glucose is stored in different parts of plant such as grains, stem and roots while oxygen is released in the atmosphere.
The answer should be
B Both anabolic and catabolic reactions took place in the seed and tree when it was young and growing and both continue now even though the tree reached a stable mass.
The trees should be capable to do both anabolic and catabolic reaction when it is seed or when it is already a big tree. Anabolic reaction happens when the plant making bigger molecule from many smaller molecule, such as in photosynthesis. Anabolic reaction could increase the mass of the plants or be used to make food. Catabolism reaction used to extract energy from the food.
The first step in the formation of the human embrayo and it is called fertilization.
<h3>What is fertilization?</h3>
The first step in the formation of a human embrayo is called fertilization. The term fertilization has to do with fusion of the male and female gametes to form a zygote.
Hence, the diagram as shown is the first step in the formation of the human embrayo and it is called fertilization.
