Answer:
The correct answer would be meiosis.
In diploid organisms, meiosis is the process that results in the formation of four haploid daughter cells from single diploid parent cell. Each of the daughter cell contains half the number of chromosomes present in parent cell.
It results in the formation of haploid gametes (sperm in males and eggs in females) which is essential in the process of sexual reproduction.
The fusion of gametes results in the formation of diploid zygote that is, maintains the diploid nature of the organism.
Hence, in absence of meiotic division the chromosomal number would keep on doubling after each generation.
In addition, crossing over (exchange of genetic material between non-sister chromatids) also takes in the prophase-I of meiosis I. It increases the genetic variation within organisms of the species. It may add survival adaptations to the population.
the other answer is wrong its d
<span>Its not actually just one system if you look at it, there are various interdependent system that actually manages every movement of every system in order to maintain homeostasis, plainly every set function is a coordinated body system response. For example, the digestive system digests food because of the enzymes and the cells and organs present in its system but again, this is aided by the different hormones which is part of the endocrine system, interdependently. Thus eventually, the circulatory system is the organ system that intiates in dissemination of the different processed and intially metabolized nutrients in the digestive system and sent throughout the body. Incidentally, also the immune system acts as agent in again many systems to maintain the so-called homeostasis. </span>
The correct answer is B.individual
Biosphere, ecosystem, and population, are all found on higher levels of ecological organization.
For the answer to the question above, I believe the answer to your question is <span>Insertions, but not deletions can change the codon reading frame.
Mutations can be useful to the organism. That is the most accurate among the given choices.</span>
revised: The correct options are:
-Mutagens and meiosis are two sources of mutation.
-A single-base insertion is usually more harmful than a single-base point mutation.
-Mutations can be useful to the organism.
