Tetraploidy will occur.
<h3><u>Explanation</u>:</h3>
The process of sexual reproduction is very necessary to maintain the genetic setup of the species over the races.
The normal chromosome content of a cell is called diploid state of cell. Its represented by the expression 2n. The cell division that takes place before the gamete formation is called meiosis. This cell division makes the chromosome number of the cells halved. So haploid cells are produced. Its represented by n.
Now as the gametes fuse, both the n becomes 2n and diploid state is regained.
But if the meiosis don't occur in the gametes, the gametes will remain 2n. So after fertilization, it becomes 4n. This state is called tetraploidy.
Answer:
Soil erosion causes siltation in rivers, dams, etc. In some areas, huge river deltas are formed (such as River Nile delta) because of soil erosion. Such places are good for agriculture but not good for urbanization. However, some people do not care about it, they just want to construct buildings on alluvium type soils.
Answer:
NO
Explanation:
The animal cell and plant cell are both eukaryotic cells. Eukaryotic cells are the type of cells that contains membrane-bound organelles, such as the nucleus, mitochondria, Golgi apparatus and a cytoskeleton.
The cytoskeleton, which is composed of microfilaments, internal filaments, and microtubules, <u>is present in both the animal and plant cells.</u>
However, some of the organelles that are not present in both the animal cell and the plant cell are centrosome and lysosomes.
<u>The </u><u>lysosome</u><u> is present only in the animal cell.</u>
Answer:
sex cells known as gametes
Explanation:
These are the risk factors associated with the development of ovarian cancer:
1. Over 40 years of age.
2. First pregnancy after 30 years of age.
3. Family history of cancer.
4.High fat diets
5. Endometriosis.
6. History of heavy bleeding.
All these factors increase the probability of having the disease.
