Explanation:
- 3.1.1
Cytokinesis is the process whereby the cytoplasm of a cell divides into two in order to accommodate the already divided nucleus.
- 3.1.2
Cancer is a medical condition that means an uncontrolled division or growth of cells.
- 3.1.3
Metaphase is a stage of mitosis where chromatids line up at the equator of the cell i.e cell plate.
- 3.1.4
Centromere is a point where sister chromatids i.e. replicated chromosomes are joined before separation in the anaphase stage.
- 3.1.5
Tumour is the term given to a mass of cancerous cells. Cells repeatedly divide without control to form a mass called tumour.
- 3.1.6
Carcinoma is a type of skin cancer or rather a cancer that begins in the skin.
- 3.1.7
The cell cycle involves the interphase and mitotic phase. Interphase stage is the stage where the cell grows, multiplies its genetic material and generally prepare while mitosis is the nuclear division.
- 3.1.8
Carcinogens are biological or chemical substances that causes cancers. They are said to be factors that induce cancer.
- 3.1.9
Benign tumor are mass of cancerous cells that do not spread to other parts.
- 3.1.10
A chromatid is the half part of a replicated chromosome. Together, they are called SISTER CHROMATIDS.
Answer:
Tape worm and a human
Explanation:
This is because a tape worm is a parasite that destroys and eats the nutrients in the human intestines to live while killing the human.
Answer:
B
Explanation:
because of osmosis as it goes from low to high
Variations are beneficial for the survival of the species. Populations of organisms fill well-defined places, or niches, in the ecosystem, using their ability to reproduce.However, if some variations were to be present in a few individuals in these populations, there would be some chance for them to survive.
Answer;
-Allele frequencies
The hardy-weinberg principle states that allele frequencies in a population do not change unless outside factors affect the gene pool.
Explanation;
Hardy-Weinberg principle is a mathematical model that describes how genotype frequencies are established in sexually reproducing organisms.
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow.
