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
Photosynthesis is a term used to describe a process that combines two other words. This is the method that plants employ to harness solar energy. The words "photo" and "synthesis" both refer to the use of light.
The process by which plants, algae, and some microorganisms convert sunlight, carbon dioxide (CO₂), and water into food (sugars), oxygen, and other compounds is known as photosynthesis.
Chloroplasts, a type of plastid (an organelle with a membrane) that is typically found in plant leaves and which performs photosynthesis, are an organelle that contain chlorophyll.
Oxygenic photosynthesis and anoxygenic photosynthesis are the two different types of photosynthetic processes. They both adhere to very similar principles, although oxygenic photosynthesis, which is found in plants, algae, and cyanobacteria, is more prevalent.
Light energy is used in oxygenic photosynthesis to convert water (H₂O) absorbed by plant roots in the form of CO₂ and generate carbohydrates. In this process, the water is "oxidised," or loses electrons, while the CO₂ is "reduced," or gains electrons. Carbohydrates are generated along with oxygen.
By absorbing the CO₂ that is created during respiration and delivering oxygen back into the air, oxygenic photosynthesis acts as a counterweight to respiration.
