Gregor Mendel chose to use purebred plant is his experiments enabled him to focus on the relationship between hybrid plants. He is considered the father of genetics today.
<span>Gregor Mendel was born on July 22, 1822, in a small farming town in Czechoslovakia. His natural interest in science and hereditary science led him to start his experiments with the pea plant. He chose the pea plant because he needed parental plants which had constant and differentiating characteristics. He first tested a plant's ability to propagate non-hybrid family lines. He discovered that the pea plant produced family lines with the most consistent characteristics. </span>
<span>Vesicles are small, membrane-bounded spheres that contain various macromolecules. Some vesicles, as we have seen, are used to transport macromolecules from the endoplasmic reticulum to the Golgi body, and from the Golgi body to various destinations. Special kinds of vesicles perform other functions as well. Lysosomes are vesicles that contain enzymes involved in cellular digestion. Some protists, for instance, engulf other cells for food. In a process called phagocytosis, the protist surrounds a food particle and engulfs it within a vesicle. This food containing vesicle is transported within the protist's cytoplasm until it is contiguous with a lysosome. The food vesicle and lysosome merge, and the enzymes within the lysosome are released into the food vesicle. The enzymes break the food down into smaller parts for use by the protist.</span>
Answer:
maintaning the essential internal parameters relatively constant is the phrase that best describes the process of homeostasis.
