The answer is B because class of drugs known as expectorants.
Conjugation
The process by which isogamous organisms exchange genetic information during fertilization is called conjugation.
In process of meiosis. The hypothalamus or the master gland in most animals, including humans send signals to the ovaries and testes of the reproductive system. In response to these signals, these ovaries and testes undergoes thesex cells division which is called meiosis<span>. </span>Spermatogenesis <span>in male gametes, is the process of sex cell division among sperm cells. On the other hand, </span>oogenesis<span> is for the female gametes. These cell divisions among respective gametes produces haploid cell which only contain one pair of chromosomes, in number -23.<span> </span></span>
There are number of endemic species, because island isolation promotes allopatric speciation and the latter occurs when species become separated from each other to the level that prevents genetic recombination.
An area where soil has eroded experience loss of nutrients. The topmost layer of soil is called the topsoil and is the most fertile. Soil erosion results in the loss of soil fertility and makes the land barren
The main cause of soil erosion is the removal of vegetation, which exposes the topsoil to water and wind. Wind and water are the main agents of soil erosion.
Water erosion can be sheet erosion, rill erosion, gully erosion or riparian erosion.
I think a frameshift mutation that occurs very early in a protein sequence would have an effect on the structure of the protein such that the primary, secondary, and tertiary structures would be altered. A frameshift mutation occurs when a protein is drastically altered because of an insertion or a deletion. Insertions and deletions cause a change in the length of a gene, which causes a shift in the codon reading frame.
