The main function of the respiratory system is to allow the exchange of gases between the atmosphere and the lungs.
Hence,the only structure that carries out this function is the alveoli as other structures such as the nose,trachea and pharynx transport gases to the alveoli just so that it can can out its function.
Cuz they combine during fertilization and since 2 halves = 1 whole, u get gametes w a full number of chromosomes
The cell's series of tunnel-like membranes functioning in transport and storage are the Endoplasmic Reticulum.
What are the functions of the Endoplasmic Reticulum?
In both plant and animal cells, the endoplasmic reticulum is a network of tubules and flattened sacs that perform a number of tasks.
The structure and function of the two ER regions are different. Ribosomes are affixed to the cytoplasmic side of the membrane in rough ER. Ribosomes are not linked to smooth ER. The smooth ER is often a tubular network, whereas the rough ER is a collection of flattened sacs.
Rough Endoplasmic Reticulum (RER)
Endoplasmic Reticulum in rough shape. Membranes and secretory proteins are produced in the rough endoplasmic reticulum. Protein synthesis is carried out by translation on the ribosomes affixed to the rough ER. The rough ER generates antibodies in certain leukocytes (white blood cells). The rough ER creates insulin in pancreatic cells.
Smooth Endoplasmic Reticulum (SER)
The production of carbohydrates and lipids is one of many tasks performed by the smooth ER. Cell membranes must be built using lipids like cholesterol and phospholipids. Vesicles that deliver ER goods to various locations also use Smooth ER as a transitory place.
Hence, the correct answer is the Endoplasmic reticulum.

# SPJ4
I think the answer is A because the inputs for the process of photosynthesis is sun, carbon dioxide, and water and the outputs are heat and oxygen.
The right answer is 50% (a half).
The sperm that fertilizes the egg (X chromosome carrier) can carry both an X chromosome or a Y chromosome, so the chances are equal, which means that there is as much chance that fertility gives birth to a girl (two X chromosomes) than to give birth to a boy (X and Y chromosome).
