Answer:
<h2>Agree
</h2>
Explanation:
1. Through mitosis, Parental cell divide into two daughter cells with same number of chromosomes.
While meiosis produce 4 daughter cell from a single cell with half the number of chromosomes as compared to parental cell.
2.Meiosis have two cycles , i) meiosis I and ii) meiosis II.
3. In meiosis I, chromosomes first go replication and become double, then cell inter into meiosis I then into meiosis II and finally produce four haploid daughter cells. It is the first step (meiosis I) that generates genetic diversity. During prophase I of meiosis I (meiosis) homologous chromosomes pair and form synapses, a special step of meiosis, which is the main reason of causing diversity.
4. There is crossing over which produce genetic diversity between gametes.
Answer: it’s A
explanation:
Answer:
Y chromosome
Explanation:
The presence of the Y chromosome indicates a male, whereas the absence of it indicates a female.
A, the others are unrealistic speeds.
Answer:
Acid -fast organisms resist decolonization by an acid alcohol wash because of high concentration of<u> lipid</u> in their cell wall.
Explanation:
Acid fast organisms contain a wax like impermeable cell wall which contain mycolic acid and large amount of fatty acid,waxes and complex lipid.Acid fast organisms are highly resistant to disinfectants and dry condition Mycobacteria possess thick waxy cell wall rich in mycolic acid. This makes it difficult to be stained using Gram's techniques. But with the use of carbon fuschen,the cell wall can be stained using acid-fast technique.
