The answer is Ribosomes.
Ribosomes are supramolecular complexes of proteins and ribonucleic acid, present in all cells. Ribosomes are organelles of the cytoplasm of a cell are composed of water, proteins and RNA, and whose function is to participate in the synthesis or manufacture of proteins from the information contained in the DNA, which arrives transcribed to ribosomes in the form of RNA messenger (mRNA).
Kidneys are the structure of the excretory system in humans is responsible for converting ammonia into urea. Lungs is used to filter air and separate oxygen from carbon dioxide (respiratory system); Liver produces juice that furthers the digestion (digestive system) and skin can be part of the excretory system because of the sweat glands.
A) space and water.............
Stem cell transplantation is used to treat a disease that is caused by a malfunctioning organ.
Embryonic stem cells (ESCs) are pluripotent and can be used for studying the regeneration of infected tissues. Consent of the person is important who is donating the ESCs. The method to isolate ESCs involves the destruction of an embryo, which is a human at the embryonic stage. The safety of the donor is another aspect, as the oocyte harvesting process may have harmful effects on the donor.These can be used to redevelop a diseased tissue and organ of the body. ESCs can be used in the regeneration of diseased tissues or organs and can help in curing diseases such as Alzheimer's, diabetes, heart diseases, etc.
Efficiency and safety of drugs can be tested on the specific organ developed using ESCs. There is no harm in using ESCs for beneficial purposes with the consent of the donor. Regular medication is required so that the organ is not rejected by the immune system after the transplant.

No its C ,i typed in D and it said it was C on USA Test prep
The correct answer is gases oxygen and carbon dioxide, which diffuse freely across the shell of an egg.
The four specialized membranes of the amniotic egg are amnion, chorion, yolk sac, and allantois. The chorion and the allantois exchange gases between the embryo and the air. Oxygen and carbon dioxide diffuse freely across the shell.
An eggshell refers to the outer covering of a hard-shelled egg and of some kinds of eggs with soft outer coats. The shells of the amniotic eggs are calcareous, formed of calcium carbonate.
The new root cells come from the root of the plants that start out with indistinguishable cells as the new plant is emerging, and those cells grow and differentiate into more specialized cell types. The root, cut in a cross-section, reveals several different specialized layers with different kinds of cells.
behind the root cap is the answer
The outer covering of a reptiles egg is hard to protect it from harm while growing. :P
I hope this helped :D
