What happens to a cell cycle when cancer occurs?

Biology
2 answers:
sammy [17]2 years ago

Answer:

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Explanation:

Superficially, the connection between the cell cycle and cancer is obvious: cell cycle machinery controls cell proliferation, and cancer is a disease of inappropriate cell proliferation. Fundamentally, all cancers permit the existence of too many cells.

Discuss how microbial world is divided providing at least two unique features of each if the living group
RUDIKE [14]

Microorganisms can be divided into two groups:

1. Archea

• Archea are prokaryotic unicellular organisms without cell nucleus or other membrane bound-organelles.  

• Their membrane is built from ether lipids, which differs them from bacteria’s cell membrane.

•  

2. Bacteria

• Bacteria are also unicellular prokaryotic organisms.  

• Bacterial cell membranes are made from phosphoglycerides with ester bonds. Bacterial genome is in a form of circular chromosome.  

• They reproduce by binary fission or by budding.

Besides, prokaryotes (Archea and Bacteria) a large number of eukaryotes are also microorganisms. Unicellular eukaryotes contain organelles such as the cell nucleus, the Golgi apparatus and mitochondria. Usually, they reproduce asexually by mitosis. An example of eukaryotic microorganism is Protist.

Suppose an alkane had 8 carbon atoms. How many hydrogen atoms would it have? a. 18 atoms c. 10 atoms b. 16 atoms d. 12 atoms
Delvig [45]
<h3><u>Answer;</u></h3>

A. <em>18 hydrogen atoms </em>

<h3><u>Explanation;</u></h3>
  • <em><u>Alkanes are group of hydrocarbon that are saturated</u></em>. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
  • <em><u>The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.</u></em>
  • Therefore,<u><em> an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. </em></u>Thus, the formula of the hyrocarbon will be; C₈H₁₈.

What is the first step in the life cycle of a plant that reproduces sexually?
coldgirl [10]

Answer:

The most appropriate answer would be A sperm cell fertilizes an egg cell.

In sexually reproducing organisms including plants, life starts as a single-celled zygote which is formed by the fertilization of sperm and egg.

The zygote then divides through mitotic division to form an embryo.

After fertilization In angiosperms, the ovule matures to form seed and ovary matures to form fruit.

In gymnosperms, zygote develops into a new sporophyte.
