Hope this helps :)
Protein has been the organic molecule that are polymers of amino acids. Proteins are composed of five major atoms of carbon, oxygen, hydrogen, sulfur, and nitrogen.
What are proteins?Proteins are the macromolecules that are polymers of amino acids. The monomeric units (amino acids) of the protein molecule are linked by the polypeptide bonds. They are involved in the majority of the activities that are crucial for the body to function.
The amino acid, the monomer has been composed of the carboxylic and the amine group that includes the atoms of nitrogen, carbon, oxygen, and hydrogen while the substitutional group may include the sulfur atoms. The carbon is the central atom attached to the other molecules.
Therefore, hydrogen, nitrogen, carbon, sulfur, and oxygen are the atoms of proteins.

How are photosynthesis and cellular respiration related?
Answers
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
I hope that helps determine your answer.
The product of photosynthesis are the reactants of cellular respiration.
What is cellular respiration?Cellular respiration is the process by which cells convert the energy stored in food molecules into a form of energy that can be used by the cells.
This process takes place in the mitochondria of the cell and involves the oxidation of glucose (sugar) to produce ATP (adenosine triphosphate), which is the main energy source for cellular processes. Cellular respiration has several stages, including glycolysis, the citric acid cycle, and the electron transport chain, each of which contributes to the generation of ATP. The end product of cellular respiration is carbon dioxide and water.

gland controls water balance, growth, and blood pressure
pituitary
Thymus
thyroid
pancreas
Answers
Answer:
The pituitary gland controls water balance, growth and blood pressure.
Explanation:
The pituitary gland is also called hypophysis, and is a small gland located in the skull that is responsible for secreting hormones and coordinating the activity of other glands.
Hypophysis is usually divided into two portions, adenohypophysis or anterior lobe and neurohypophysis in posterior lobe. Among other functions, the pituitary gland is in charge of
Water balance and blood pressure, through the antidiuretic hormone or ADH secreted by the neuro-pituitary. Growth, through the secretion of growth hormone or GH, secreted by the somatotropic cells of the adenohypophysis.This gland is also responsible for the secretion of oxytocin and other hormones in charge of regulating endocrine glandular activity.
Regarding the other options:
Thymus is a gland present in children and related to immune function. Thyroid is responsible for secreting hormones that control basal metabolism. Pancreas has exocrine and endocrine function, producing digestive enzymes and insulin and glucagon, respectively.Answer:
A.pituitary
