Answer laterHow many times a cell undergoes mitosis to produce 128 daughter cells? a.7 b.14 c.16 d.32
Hello Aspirant,
Hope you are doing great. To create 128 cells, the cell must divide mitotically 7 times. The formula 2n, where n is the number of divisions per cell, determines how many times a cell must divide mitotically. One cell divides into two during mitosis, and both daughter cells have the same number of chromosomes as the parent cell. 8. The mitosis formula is (2n 2) / 2.

Y chromosome is less active why
Dear Aspirant, since Y-chromosome possesses small amount of euchromatin that contains DNA or genes, therefore it is genetically less active. Recent research has shown that the Y chromosome has developed some pretty convincing mechanisms to "put the brakes on", slowing the rate of gene loss to a possible standstill. I hope you are clear now. If you have any other doubts feel free to ask. All The Best!!!
difference between indirect and direct development
Hello,
The major differences between direct and indirect development are mentioned below:
| Direct development | Indirect development |
| In this type of development, an embryo develops into a young one without any intermediate larval stage | In this type of development, an embryo develops into a young one with some intermediate larval stages. |
|
Seen in fishes, reptiles, birds and mammals
|
Seen in invertebrates and amphibians
|
|
Young ones resemble the adult |
Young ones do not resemble the adult |
how many and which questions were repeated in neet 2020?
Dear Aspirant,
the repeated questions for NEET examinations are generally in most cases low, as the level of competition is very high. In most cases similar kinds of questions are asked instead of repeating the same question. However, there are a few times where a question or two are repeated from the previous years. Hence to get to know of some of these repeated questions or similar questions that are asked through out the year in NEET, you may solve the previous years question papers. They are very beneficial as it not only gives you an idea of the similar questions but also helps you get familiar with question paper pattern.

what is chemosynthetic autotrophic?
Hey student,
Chemosynthetic Organisms are those organisms which obtain their food using the chemical energy present in inorganic molecule.
Chemosynthetic autotrophic are those organisms which use inorganic substrates as energy source and CO2 as carbon source and synthesize their own food and doesn't depend on other organisms for food. In simpler words, an autotroph that is capable of synthesizing complex organic materials from inorganic reactions.
I hope it helps.

Hope it helps.
fungal cell wall is composed of
Hello,
The cell wall is a characteristic structure of fungi and is composed mainly of glucans, chitin and glycoproteins. As the components of the fungal cell wall are not present in humans, this structure is an excellent target for antifungal therapy. The major constituents of the fungal cell wall are chitin, glucans, and glycoproteins. Chitin is a structurally important component of the fungal cell wall located closest to the plasma membrane.
