Answer:
Cancer is a collective name for many different diseases caused by uncontrolled cell division.
Explanation:
Cancer is the kind of disease that will result from uncontrollable cell division despite cellular or genetic damage.
What is the relation between cell cycle and cancer ?
The relationship between the cell cycle and cancer is intuitive on the surface: the cell cycle regulates cell proliferation, and cancer is a condition caused by uncontrolled cell proliferation. Fundamentally, all tumors allow for an excessive number of cells to exist.
Cells have a variety of methods that they can use to control cell division, fix DNA damage, and stop the growth of cancer. As a result, it is believed that the development of cancer occurs through a number of steps and requires the failure of several different mechanisms before a critical mass of malignant cells is reached.
The majority of malignancies develop specifically when cells have a variety of mutations (changes in DNA) that cause them to cycle more rapidly, evade internal and external restrictions on division, and prevent planned cell death.
Thus, uncontrollable cell growth indices to cancer.

Protein promotes metabolic reactions, supports tissue growth and repair, and synchronizes biological processes. Proteins give your body a structural foundation while also ensuring optimal pH and fluid balance. Thus option B, C, D is correct.
What is function of protein?Amino acids make up proteins. These substances aid in transforming T cells, B cells, and antibodies—important immune system components—into germ-fighters that recognize and eliminate potentially infectious cells as they enter your body.
Amino acid chains are the building blocks of proteins, which fold into distinctive three-dimensional structures.
The final folded shapes of proteins are well-suited for their tasks, and the bonds inside protein molecules assist to stabilize their structure.
An enzyme is a biological catalyst that speeds up a chemical reaction without changing its equilibrium, according to a short and straightforward definition.
Therefore, protein perform a wide variety of functions in a cell.

While Kepler supported the Copernican model of the universe, Kepler concluded the following:
A. The circular orbits of the Copernican model weren't correct. Paths of the planets were elliptical.
B. The circular orbits of the Copernican model weren't correct. Paths of the planets were rectangular.
C. All other bodies in the universe move around the moon in triangular paths.
D. All other bodies in the universe move around the earth in circular paths.
Given the laws put forward by Kepler, we can conclude that option A is correct, he proved that the orbits of the planets were in fact elliptical.
Though options B and C are false due to the impossible nature of the shapes they describe for planetary orbits, option D is also false but is something that many astronomers once believed. It wasn't until the Kepler observations that this theory was proven to be false.
Kepler believed in the Copernican model of the universe, in which the planets revolved around the sun, but through measuring and observing the movement of mars, he would come to the realization that the orbits of the planets were in fact not circular as he and many other believed, but rather elliptical in nature.

a. What are two variations, or different versions, of this trait?
Bacteria can be SUSCEPTIBLE or RESISTANT to antibiotics. Susceptible bacteria can't grow if the drug (i.e., the antibiotic) is present.
Susceptibility to antibiotics occurs when bacterial colonies can't grow in presence of the antibiotic (e.g., erythromycin).

Put the steps of HIV cellular infection and replication in the correct order:
- The T helper cell is killed.
- New HIV virion is assembled.
- New HIV buds off the T helper cell getting it's envelope while the Protease enzyme matures the new virus.
- The Integrase enzyme integrates the viral genome with the T helper cell's genome.
- Uncoating of the capsid.
- Reverse Transcriptase turns the ssRNA genome into ds DNA.
- Merging of viral envelope with the T helper cell membrane.
- The T helper cell copies the HIV genome and makes HIV proteins.
- Attachment of the gp proteins in the HIV envelope to CD4 on the T helper cell.
holy person produces antibodies to packages that invade the body. But with the infection of H. I V, the body was, is the ability to produce antibodies and how is that possible? Um, and it shows that the matter said Axe and destroys CD for he cells, which help Erkki South. So we have determined the function of this and how we can affect, as we see in this of antibody production. So basically, the helper peace. So is the middleman in turned immune response. So we have an antigen presenting cell that presents an androgen that activates Alberti sell. The activation of that T cell releases side of kinds that activate B cells. Activation of B cells triggers proliferation of plasma cells, which Ruiz antibodies and thus is able to fight the whatever pathogen has entered the body. But if the virus directly kills off helper T cells, then there's no way for the immune system to actually launch a defense against HIV or any other pathogen. Because the cells and T cells, which carry out cell mediated and Hugh Meral immune responses, are not able to be activated and carried out. So let's see which answer best matches that a cease the CD 40 sells a record intermediate are required intermediate in a series of salty cell signal events that must be completed before B cells. Commager. Yes, that is true. As depicted by this diagram. Let's see if there's any other true statements he states the city for T cells have CD four molecules Cove in when we bound to their source cell surfaces and do not induce apoptosis and other cells during an immune response. So, really, we have nothing to the inducing a pop doses really has nothing to do with, uh, the question. It also does not see the forties city for T cells do not induce apoptosis. So that is just a false statement. Um, and it's just not relevant to the question. See, states That CD for T cell counts are about 1000 per micro liter and a healthy person, but drop over 400 per micro liter. So once again, this is not relevant to how C D four T cells and the loss of them, uh, contribute to the loss of any body synthesis. And D says that CD four cell precursors air formed in the bone marrow and then migrate to the thymus where they developed their T cell receptors. So once again, not relevant. So we can see that B, C and D are just irrelevant to the question of antibody synthesis and the connection to CD four C T cells, which, uh, the correct answer to is a
