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:
The correct answer will be amino acids.
Explanation:
The process of protein synthesis takes place in an organelle called ribosomes. The ribosome reads the information coded in the mRNA in the form of triplets of nitrogenous bases also known as "codons". The codons code for specific amino acids which are assembled or joined via peptide bonds in the ribosomes.
In the question, Katie wanted to make doghouse of the wood and nails in which if doghouse represents the protein, the nails and wood will represent the basic unit or monomer of a protein called amino acids which are put together by a hammer.
Thus, amino acids are the correct answer.
