dolphi86 [110]
<span>the correct answer is B. the information that decides the characteristics of all organisms are contained in their nucleic acids. Nucleics acids are DNA and RNA. DNA have genes that code for proteins which are responsible for the structural and functional characteristics of organisms. DNA is transcribed into RNA and RNA is translated to proteins. Therefore information that is in these nucleic acids determines all the characteristics of organisms</span>

Superficial region around the renal medulla
nalin [4]

Answer:

Renal cortex

Explanation:

The renal medulla of a kidney is surrounded by renal cortex. The renal cortex is the granulated layer. It is the renal cortex in which the renal corpuscle (glomerulus and Bowman's capsule) are present. The renal cortex is reddish brown in color. This is due to the fact that most of the renal arteries deliver the blood to the cortex.

Duroc Jersey pigs are typically red, but a sandy variation is also seen. When two different varieties of true-breeding sandy pig
alexgriva [62]

Answer:

The dihybrid proportion for Mendelian example of legacy regularly gives a few deviations attributable to epistasis. One of these proportion incorporate the example of 9:6:1 proportion as opposed to ordinary 9:3:3:1. This proportion can be credited to nearness of copy qualities with total impacts. As per the above model, it very well may be seen that guardians are unadulterated rearing red and sandy in shading. Be that as it may, their offspring show up as red, sandy and curious white pigs in the proportion of 9:6:1 individually.  

Explanation:

The information and perception recommend that the qualities liable for red shading and sandy shading are copy in nature and in total, they give sandy shading to the pigs. Be that as it may, nonappearance of any of these alleles in either homozygous or heterozygous condition neglects to produce a coat shading and a vapid white pig is raised. This likewise proposes deviation of Mendelian example of legacy occurs right now to explicit intuitive conduct of these two qualities for red and sandy coat hues. Disappointment of cooperation of these two alleles brings about white pig while nearness of both the alleles results in between allelic association and surprisingly, an extremely enormous number of sandy pigs are watched. Aggregately, it very well may be deciphered that both the qualities are predominant over one another. These alleles produce an alternate phenotype when present alone however produce an impossible to miss phenotype when present together due to between allelic associations. Significantly, it's anything but an instance of essentially added substance conduct of alleles in such a case that it had been, another phenotypic coat shading would have been acquired. Be that as it may, since the F1 offspring resumes the shading like their folks, it speaks to an instance of epistatic copy qualities.

Why is it important that nadp+ reductase is on the stromal side of the thylakoid membrane?
mina [271]
It is important that the FNR or Nadp+reductase enzyme is on the stromal side or covering of the plant's Thylakoid membrane because they participate in photosynthesis. NADPH cycling can only be achieved with light and cannot operate in the dark and stromal side provides the needed light.
