<span>Cancerous tumors are divided into broad groups on the basis of the particular type of tissue from which the tumor cells arise. this is called histogenesis.
</span><span>Tumors are of different types, some are cancerous and some are benign (non-cancerous). In a disease of cancer, there is an abnormal cell growth. It is characterized as out of control cell growth.</span>
I think the correct answer from the choices listed above is option B. The metabolic pathway that is correctly paired with an example would be anabolism -photosynthesis and protein. Anabolism is the process where the body utilizes the energy released by catabolism. Hope this answers the question.
Precise but not accurate,the real temperature inside the refrigerator is 37 degrees C. The thermometer isn’t accurate (it’s almost two degrees off the true value), but as the numbers are all close to 39.2, it is precise.
Answer:
Hydrophilic heads facing exterior
Hydrophobic tails facing interior
Explanation:
In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.
Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.
The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.
The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
