Answer:

tumor suppressor gene

Explanation:

A tumor suppressor gene is capable of modulating cellular processes during cell division and/or replication, thereby avoiding uncontrolled cell proliferation and tumor development. For example, the p53 gene is a tumor suppressor gene that encodes a protein (p53) which is well known to regulate critical cellular processes such as, for example, cell cycle arrest and programmed cell death (apoptosis). Moreover, breast cancer genes BRCA1 and BRCA2 are tumor suppressor genes that regulate the repair of damaged DNA through the Homologous recombination (HR) pathway. In consequence, mutations in BRCA1 and BRCA2 genes can increase the risk of developing breast cancer.

Can anyone explain it? The one I chose is what I think is correct...
Kitty [74]

Although I don't know for sure what is an epicycle, I think your answer is right and I would try to explain as apliable to solar systems on the Milky Way known through astronomical discoveries, conside ring just one star called "Sun" and a few distant planets describing a certain type of movement around it. I should add that the Moon describes the same type of movement around the Earth ( which is not a star), being the only natural satelite of the planet Earth, being kept around it by the circumstances created by the proportion of forces occured while moving

3. How do amphibians make up the deficiency in their circulatory system?
daser333 [38]

Answer:

Modern amphibians are characterized by the flexibility of their gaseous exchange mechanisms. Amphibian skin is moistened by mucous secretions and is well supplied with blood vessels. It is used for respiration to varying degrees. When lungs are present, carbon dioxide may pass out of the body across the skin, but in some salamanders there are no lungs and all respiratory exchanges occur via the skin. Even in such animals as frogs, it seems that oxygen can be taken up at times by the skin, under water for example. Therefore, regulation of respiration occurs within a single species, and the relative contribution of skin and lungs varies during the life of the animal.
