Answer: haploid, 23 chromosomes and 23 chromatids of
Explanation:
Meiosis takes place in two divisions meosis 1 and meosis 11.
Meiosis 1 is reduction division, because two new daughter nuclei are formed with haploid chromosomes number of the parent nucleus.
Therefore based on this question; the 46(2n) chromosomes in example the ovary will be halved to (23)n. 2n ⇒ n .
So far chromatids, are newly formed chromosomes there will be 23 chromatids, since the haploid chromosomes are 23 in number
However, so far the entire new daughter cells contains half the total chromosome number of the parents they are haploid.
Answer:
The correct answer is option d, that is, it prevents the enzyme, which degrades cyclic GMP.
Explanation:
Oral therapy for erectile dysfunction is Viagra, which is the citrate salt of sildenafil, it works by preventing a specific phosphodiesterase type 5 or PDE5, which is the inhibitor of cGMP. During sexual stimulation, nitrous oxide is released in the corpus cavernosum causing the erection of the penis in males. The nitrous oxide then stimulates the enzyme guanylate cyclase that further makes the concentration of cGMP to elevate, this generates smooth muscle relaxation in the corpus cavernosum and permitting blood the inward flow of blood.
Viagra works by increasing the influence of nitric acid by preventing PDE5, which is accountable for the deprivation of cGMP in the corpus cavernosum. At the time of sexual stimulation, the discharging of nitrous oxide takes place, the viagra inhibits PDE5 causing the levels of cGMP to elevate in the corpus cavernosum leading to smooth muscle relaxation and continuous flow of blood to the corpus cavernosum.
The microorganisms are the foundation of all forms of life on Earth, they have prevailed for about 3.5 billion years. The animals, plants, and the modern microbes have all evolved from the primitive bacteria. The life on Earth relies on their activities. According to the human's point of role, one could not survive in the absence of microorganisms.
The microbes demonstrate numerous benefits like the production of oxygen, nitrogen fixation, degradation of substances (like sewage, wastewater, and cellulose). Microbes play vital roles in the biosphere, the economic uses of microbes take place in the field of agriculture, industry, bioremediation, and medical microbiology.
Well, one of the corresponding elements that is essential for the production of ATP is phosphorus, there are 3 elements of phosphorus in the form or as a polyatomic ion with oxygen, phosphate. Speaking of which, oxygen for the above reason as it composes phosphate is also a crucial element that ultimately produces a single molecule of ATP.
