Answer:
Graafian follicle
Explanation:
Ovulation is the process observed in the females during which the females release the oocyte or the female egg cell. The process of ovulation takes place every month during the 14th day of the menstrual cycle.
The primary follicle is formed in the females before birth but after the puberty, each month the primary follicle matures into the secondary and then tertiary follicle called the Graafian follicle. This Graafian follicle releases the secondary oocyte.
Thus, Graafian follicle is the correct answer.
Answer:
The kinetochore of the chromosomes
Explanation:
<em>What could be damaged that is hindering the spindle fibers from attaching to the chromosomes are the kinetochores of the chromosomes.</em>
At the metaphase stage of the cell division, the chromosomes align at the equator of the cell and the spindle fibers engage each chromosome at a region known as the kinetochore.
The kinetochore is made up of complex proteins and lies around the centromere region of the chromosome. The microtubules of the spindle fibers attach to this region during the metaphase stage.
<u>If the kinetochore is damaged, it means the spindle fiber will not be able to attach to the chromosome. </u>
The process, primary succession, would best describe the series of photographs when all of the topsoils were destroyed after the eruption. There is just one thing to remember about this, that the primary succession occurs on the land that has nothing and is the soil building process.
Answer: Option C.
Cellulose.
Explanation:
Cellulose is a polysaccharide which is made up of glucose and it is an important component in plant cell wall. It give strength and rigidity to the cell wall. Cellulose make the cell walls strong. This play a regulatory role in tissues growth and provide strength. The cellulose is only found in cell wall and it's protect the cell wall.
