Biology

Yuri [45]3 years ago

Answer:

Explanation:

Detergent enzyme used because The positively charged sodium ions in the salt help protect the negatively charged phosphate groups that run along the backbone of the DNA. A detergent is then added. The detergent breaks down the lipids in the cell membrane and nuclei. DNA is released as these membranes are disrupted.

Proteases catalyze the breakdown of contaminating proteins present in the solution to its component amino acids. It also degrades any nucleases and/or enzymes that may be present in the sample. This is of vital importance since these chemical compounds can attack and destroy the nucleic acids in your sample.

Explain the significance of meiosis in sexual reproduction
iogann1982 [59]

Answer: Meiosis produces the sex cells, that is the gametes (sperm cells and eggs) that unite to form a zygote. Meiosis ensures that the gametes have have haploid chromosomes so that the resulting zygote from their fusion will have diploid chromosomes.

Explanation: Meiosis is a type of cell division in which a cell divides twice to produce four daughter cells each with the half the number of chromosomes as the parent cell. Without meiosis new gametes are not produced. Meiosis ensures that the chromosomes are evenly distributed among the daughter cells and that each daughter cell contains 23 chromosomes. A sperm cell with 23 chromosomes fuses with an egg with 23 chromosomes to form a zygote with 46 chromosomes. If meiosis does not occur, gametes with haploid chromosomes will not be produced, and if the gametes have diploid chromosomes because meiosis does not occur, sexual reproduction will be a disaster because when two diploid gametes fuse the resulting zygote with be abnormal.

Which statement is true about gravitational force? It is inversely proportional to mass. It increases with distance. It is an at
iogann1982 [59]
The first is incorrect because the more massive an object, the more gravitational force acts on it.

The second is false because the gravitational force decreases with distance. It's why the outer planets are usually smaller.

The third is true. It depends on both mass and distance and attracts two objects together.

The fourth is false because temperature and pressure have nothing to do with gravity.
