The answer is B because with 3/4 of the L trait being dominant, it’s impossible to have an offspring with the recessive trait
Answer:
The correct option is A. The oxygen atoms diffuse through the atmosphere and are inhaled by animals.
Explanation:
Photosynthesis can be described as a process in which plants use the light from sun to convert carbon dioxide and water into glucose. Oxygen is made as a by-product of this reaction. This oxygen is released into the atmosphere by the plants through the mechanism of diffusion.
The oxygen released into the atmosphere is taken up by animals. Animals utilize this oxygen for the process of respiration.
The process of respiration and photosynthesis are opposite to each other.
Answer:
Here are the answers:
a. 4 Cell determination as an issue in the *rest is missing*
b. 4 They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.
c. 4 I and III only
Explanation:
The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.
Cleavage Planes:
Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.
Cell Differentiation:
Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
Answer:
1838 was. the year the term protein was used.
Explanation:
Protein comes from the Greek word proteios, meaning "primary" or "holding the first place." A Dutch chemist Gerard Johann Mulder, coined the word protein in 1838.

Answer:
D, Flagella
Explanation:
Ribosomes produce proteins for the cells to function, chloroplasts provide a plant cell with photosynthesis, vacuoles provide a plant cell with holding its structure up, and mitchondria provides ATP (energy) for the cell to function.
