Chromosomes only exist inside gametes true or false

Biology
1 answer:
netineya [11]3 years ago
8 0

The male human has a sperm cell and the female has an egg cell. The cells from the male and female that combine to form a zygote are called gametes. The human sperm and egg cells each contain 23 chromosomes. . A combination of gametes forms a zygote with 46 chromosomes. The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.<span>Chromosomes get shuffled when eggs and sperm are made. Though most adult cells contain two sets of chromosomes, sperm and egg cells are different. These special cells have just one chromosome from each pair. Which chromosome they get from each pair is random, making each sperm or egg cell unique. There is also a bit of mixing before the chromosomes are sorted into individual sperm or egg cells. Chromosomes from each pair in a mother or father, respectively, make contact and exchange pieces of DNA, creating hybrid chromosomes. </span>

Musya8 [376]

Answer:

Yes.

Explanation:

Yes, small plants began to grow along the remaining soil because of the presence of seeds in the soil that sense suitable environmental condition and come out of the soil. The ashes of burn trees have huge amount of nutrients in the form of minerals that triggers the growth of small plants. After the destruction of forest, new plants grow on that land, this type of phenomenon  is called ecological succession.

What factor is a characteristic of passive transport?
Nuetrik [128]

Answer:

In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion.

It occurs without energy input. Passive transporters let something across a membrane "with the gradient" in other words, substances travel from high concentration to low concentration, which is energetically favorable.

Had you been Louis Pasteur what would have been your reflections and conclusions based on the broth &amp; left open flask experi
bazaltina [42]
Based on the broth left on an open flask experiment, wherein the boiled broth was placed in two flasks (one flask with straight neck and the other flask has a bent neck) and exposed to open air at room temperature for several weeks.

The broth within the straight neck flask has changed its appearance. It became discolored and cloudy. Whereas, the broth in the bent neck open flask still remains the same.

These results would then support the conclusion that germs in the air were able to fall unobstructed towards the straight neck flask and contaminate its contents. While, the bent neck of the 2nd open flask acted as a trap for the germs, preventing the germs from contaminating the broth. Further emphasizing that germs can only come from other germs and not from spontaneous generation.

Do you think one reproductive process promotes higher genetic variation than the other?
Alina [70]
Sexual reproduction produces far more genetic variation than asexual reproduction. I’m asexual reproduction, only one organism is needed. In this process they copy their own DNA and create an exact copy of themselves. So, if you think about it, all the offspring ever created by that one organism is going to have the same genetics as it. They’re all going to be identical. There is no variation, or differences, between any of the offspring and the original organism. Bacteria reproduces this way, although through binary fission, they can sort of reproduce sexually.
Sexual reproduction results in genetic variation. Two organisms are needed to create offspring. An egg cell and a sperm cell are needed from a female and male organism to create the new organism. Since two organisms are required, their offspring will be a mix of their DNA. This will create variation between offspring. Every new organism will have different genetics.
This is why more advanced organisms like plants and animals have different DNA even if they are the same species.
