The DNA virus uses nucleus of the host to replicate it genetic material since it lack reverse transcriptase enzyme.The similarities between the DNA virus with human protein it make difficult to treat this virus without damaging the host cell.
while
RNA virus has reverse transcriptase enzyme which is used to replicate its genetic material, but it lack ability to check errors, which led to higher mutation rate.The transcriptase enzyme is used to make vaccine which is used to treat RNA virus
Answer:
The sporangium matures and releases spores into the air. There are about 30,000 species of ascomycetes, members of the division ascomycota, commonly called sac fungi. The most well known members of this group, yeasts, are used to make bread rise and to carry out anaerobic fermentation in brewing alcohol.Apr 17, 2006
Explanation:
The correct answer is - 1.5 pounds per month.
The infants gain approximately 1.5 pounds per month in their first half year of life. With this amount of weight gain they manage to roughly double their birth weight in this period. The first six months of the life an infant are characterized by very fast grow and weight gain, as the infant passes this period that growth and weight gain decrease little by little in intensity as the child is growing older.
Answer:
2n, n, diploid
Explanation:
<em>When the somatic cells of human are in interphase, the ploidy level is denoted as </em><em>2n (diploid)</em><em>. The ploidy level of the human's gametes is denoted as </em><em>n (haploid)</em><em>. The 2n number of a human is </em><em>diploid</em><em>.</em>
Somatic cells are also known as vegetative cells and all somatic cells of humans have diploid number of chromosomes. At interphase, the number of chromosome remains diploid (2n) but the amount to DNA is doubled at the synthesis phase of the interphase.
Human gametes are formed through meiosis - the division of sex cells in the human body. Meiosis results in the halving of number of chromosomes of cells. Hence, all human gametes contain half the number (n = 23) of chromosome of vegetative cells.
Humans are diploid organisms with diploid (2n = 46) number of chromosomes in their vegetative cells.
This control is called negative feedback. Mechanism of negative feedback. Each metabolic reaction or process is regulated by several enzymes. These enzymes control the rate of these reactions and thus are fundamental in maintaining homeostasis. In a negative-feedback pathways, the end product of a pathway binds to the allosteric site of the first enzyme, closing its active site and blocking the rest of the reactions.
