Answer:Organ
Explanation:An organ may be defined as a group of tissues which perform similar functions. Organs can be found in both plants and animals,functionally related organs often cooperate to form systems. These organs are interdependent on each other to make up organ systems. Organ systems can be found in the different parts of the body. For instance,the esophagus,stomach and liver make up the digestive system and in the excretory system the skin and kidney are examples of the organs that can be found here. The main tissues of an organ tend to have the same embryological origin. This simply means that they arise from the same germ layer and by germ layer we mean the primary layer of cells that form during embryonic development. In plants however,the main organs are the roots,stem and leaves whose primary functions are to give nourishment to the plant. Reproductive organs of plants include the seed,flowers and spores which maintain the basic life processes of the plant.
Answer:
The reproductive system.
Explanation:
Without the reproductive system, humans are not able to reproduce meaning the human species would go extinct. With the reproductive system, humans are able to create more humans, in this way humans do not go extinct.
A is the correct answer, eukaryotic cells have membrane-bound nucleus, prokaryotic cells do not.
Because the genes can come from distant relatives of either parent. The environment may also affect their features
The reason that plants tend to have larger leaves on the forest floor is because the leaves need to capture more sun.
By increasing the surface area of the leaf, which also increases the amount of sun it collects, it can compete with the larger trees and vines when it is exposed to less sun due to said trees.
