A single molecule has at least how many atoms

The right answer is C

"Binary fission" is the most common form of reproduction and cell division of prokaryotes. A cell, after replicating its genetic material, divides into 2, each part containing a copy of the genetic material and 2 new perfectly individualized cells are finally created, each having the ability to grow to the size of the parent cell of origin ... The chronology is as follows:

- replication of the bacterial chromosomal DNA and segregation into two nucleoids and cell growth phase;

- assembly of a protein ring of constriction;

- constriction of the ring associated with the wall synthesis until complete individualization of the 2 new cells.

In India, there are several different breeds of sheep that are native to the country. Some of the major breeds include:

1) Nali: The Nali breed of sheep is found in the states of Rajasthan, Haryana, and Punjab. They are known for their high-quality wool and adaptability to the arid regions of North India.

Answer: 1. d. algae

Explanation:

A primitive community is the ecological community which is occupied with the  low diversity of biological species. The species located in this community includes simple organisms. The algae is an example of species that is expected to be found in a primitive community.

Answer:2 b. a natural recovery process

Explanation:

An ecological succession is a change in the biotic community of an ecosystem with respect to changes occurring in the non-living environment in due coarse of time, until the ecosystem attains stability. Succession is a natural recovery because even if any kind of natural or human induced destruction occurs in a region which is capable of reducing the population of living beings and destroy the physical environment. Some precursors of life will renew the growth and abundance of living species and the changes occurring in the physical environment will support the growth.

The Answer is d.
