Answer:
a. disruption of mitotic spindle formation.
Explanation:
Vinblastine is a chemotherapeutic drug which is used to restrict cancer cell proliferation. During metaphase, it binds to microtubular proteins which play a very important role in mitotic spindle formation. If spindles will not form then during anaphase, the sister chromatids will not separate and mitosis will not take place. This is how hyper-proliferative cancerous cells are controlled from dividing and cancer is treated using this drug.
About 38% of animal protein comes from fish
Answer:
Autorophs are living organisms that make their food through photosynthesis while heterotrophs are living organisms that can not make their own food, so they must eat it.

The options are:
A.
They are genetically different from the parent because they are produced by sexual reproduction.
B.
They are genetically identical to the parent because they are produced by sexual reproduction.
C. They are genetically identical to the parent because they are produced by asexual reproduction.
D.
They are genetically different from the parent because they are produced by asexual reproduction.
Answer:
The correct answer is- C. They are genetically identical to the parent because they are produced by asexual reproduction.
Explanation:
<em>E. coli </em>reproduces through binary fission in which the genetic material of cell of <em>E. coli</em> first duplicates and then the cell elongates and each of the copies of their genetic material is moved to opposite poles.
After this, the cell gets divided into two equal daughter cells. As binary fission is an asexual reproduction so there is no mixing or combination of genetic material from other <em>E.coli</em> therefore the resultant daughter cells are identical to the parent cell.
Therefore the correct answer is option c.
The cells are angular, rigid, and have a cell wall made up of cellulose. This sample most likely came from a plant.
- Chloroplasts, cell walls, and intracellular vacuoles are a few characteristics that set plant cells apart.
- Chloroplasts are responsible for photosynthesis, cell walls provide plants the strength to stand upright, and vacuoles control how cells handle water and store other molecules.
- Plants have a specific cell wall in addition to a cell membrane. Cellulose, a thick material containing several sugar units, makes up this.
- This allows plants to seem rigid and robust because of their thick feature.
- Human cells, in contrast, lack a cell wall and are more flexible and spherical than plant cells.
