The assortment of genes is determined by metaphase 1 and 2 because thisnis where the chromosomes line up and where they will be sent (and separated) is determined now.
The nitrogen fixation is a very important process because it is the principal source of nitrogen in the marine environment for photosynthetic plants. Nitrogen is a growth limiting nutrient, that is very important for the growth of photosynthetic plants. During the process of nitrogen fixation, nitrogen is absorbed from the atmosphere and it is fixed by nitrogen fixing organisms.
The correct answer is that "<span>RNA polymerase binds to the promoter, which precedes the gene only on the template strand of DNA."
A gene is best described as </span>a chain<span> of DNA or RNA which codes for a molecule that has a </span>characteristic<span>. </span>for the duration of<span> gene expression, the DNA is first duplicated into RNA. The RNA </span>can be immediately practical<span> or be the intermediate template for a protein that </span>plays<span> a </span>characteristic<span>. The transmission of genes to an organism's offspring is </span>the idea<span> of the inheritance of phenotypic </span>traits<span>.</span>
Answer:
The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body.
The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs.
It also includes chemical barriers such as mucus, gastric acid, bile, tears, sweat, and saliva.
The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera.
Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.
