Answer:
Like healthy cells, cancer cells cannot live without oxygen and nutrients. So they send out signals, called androgenic factors, that encourage new blood vessels to grow into the tumor. This is called parthenogenesis. Without a blood supply, a tumor can't grow much bigger than a pin head.

The kidneys are powerful chemical factories that perform the following functions:
- remove waste products from the body.
- remove drugs from the body.
- balance the body's fluids.
- release hormones that regulate blood pressure.
- produce an active form of vitamin D that promotes strong, healthy bones.
Answer:
Metabolism refers to chemical reactions that occur within the cells of living organisms -that involve the interaction of substrates, co-factors and enzymes to obtain a product- while homeostasis refers to the internal balance within the body.
Explanation:
<u>Metabolism</u> involves a series of processes that occur in order to obtain a result or product necessary for life. Exist chemical reactions that are part of various metabolic pathways, where chemical substances are transformed into others through the intervention of specific substrates and enzymes. In metabolism reactions can be
:
- Anabolic, when necessary molecules are constructed or synthesized, such as the biosynthesis of proteins from amino acids
- Catabolic, when a substrate is broken down to obtain a product, such as glucose to produce energy (ATP)
.
<u>
</u><u>Homeostasis</u><u> </u>is the maintenance of the proportion of elements for the body to function properly. It is the equivalent of internal balance, which makes use of internal regulation mechanisms.
<em>
A correct functioning of the metabolic reactions guarantees an adequate homeostasis, and the balance that is required for the organism to function properly, implies a regulation of the metabolic processes that occur.</em>

<h3>Explanation:</h3>
Mitosis actually happens in four phases. The first phase of mitosis through which chromatin condenses into chromosomes, the nuclear case breaks down, centrioles divide, and a spindle begins to form. Microtubule fibres that enable the division of sister chromatids during mitosis and meiosis.
