Answer:
D: Simple Diffusion
Explanation:
Diffusion is a transport driven by a concentration gradient. Gas molecules move from a place of high concentration to an area of low concentration. Knowing when blood is low in concentration and high in carbon dioxide it goes under gas exchange with air into the lungs.

Answer:
The correct option is a. Fibrocystic breast disease refers to the progressive development of fluid-filled cysts and fibrous tissue.
Explanation:
Fibrocystic breast disease is characterized by benign (non-cancerous) changes in fibrous tissue. These changes may include irregular lumps or cysts (Breast cysts are sacs full of fluid inside the breast) which tend to mix with the surrounding fibrous tissue, breast swelling, nipple tenderness. Fibrocystic breasts are composed of tissue that can have a lumpy or rope-like texture. Which is called "nodular or glandular breast tissue" in it, there are observable characteristics of the disease through the microscope as: a prominence of fibrous tissue, excessive growth of the cells lining the breast ducts, enlargement of the mammary lobes and the fluid-filled cysts.
Mendel prevented self-pollination by the pea plants by removing the pollen-bearing part of the plant.
<h3>Mendel's Experiment</h3>
Mendel conducted several plant breeding experiments to study how traits are inherited in living organisms using the pea plant.
In some of the experiments, he needed the plant not to self-fertilize. Thus, he decided to remove the polling-bearing part of such plants.
The pollen-bearing part of a plant is known as the anther. By doing so, the male gamete, which is the pollen, will not be available to fertilize the female gamete of the same plant.
