Agata [3.3K]

Answer:

Just letting you know that the meaning of a vestigial structure

Explanation:

It is a structure that has no purpose. For ex. a pig's back toe has no purpose it's just there. It doesn't function

ACE inhibitors work on the renin-angiotensin system to prevent the conversion of angiotension I to angiotensin II. Because this

stich3 [128]

Answer:

c) unrelenting cough

Explanation:

ACE inhibitors stand for Angiotensin-converting-enzyme inhibitors.
ACE inhibitors are used for the treatment of high blood pressure and heart diseases.
These inhibitors perform their action by causing a relaxation of the blood vessels which results in decreased blood pressure.
Further, these inhibitors prevent the conversion of angiotensin I to angiotensin II and the site of this conversion is the lungs, since this conversion is blocked by these inhibitors, an unrelenting persistent cough is a common side effect associated with the use of these inhibitors.

If the concentration of hydrogen ions (H+) outside of the thylakoids were equal to the concentration of H+ inside the thylakoids

erik [133]

The chloroplasts would be unable to generate ATP

If the concentration of hydrogen ions (H+) outside of the thylakoids were equal to the concentration of H+ inside the thylakoids, the chloroplasts would be unable to generate ATP

Explanation:

As the high-energy electron from the reactive center of the photosystem conveyed from one protein to another in the protein transport chain of the chloroplast, the energy harnessed from the electron is used to pump H+ ions into the thylakoid lumen against concentration gradient.

The proton motive force created by having a high concentration of H+ ion in the thylakoid lumen than outside is to enable the creation of potential energy that is tapped by ATP synthase to create ATPs in a process called photophosphorylation. The ATPs made in this light stage is used in the anabolic process of the dark stage to make glucose through the reduction of CO2

A corn plant known to be heterozygous at three loci is testcrossed. The progeny phenotypes and numbers are as follows:+ + + 455a

astraxan [27]

Answer:

The progeny phenotypes and numbers are as follows:

+ + + 455-------- parental

a b c 470-------- parental

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

+ b + 460---------- parental

a + c 475----------- parental

Total 2,000

+ + + 455-------- parental

a b c 470-------- parental

+ b + 460---------- parental

a + c 475----------- parental

It is two point testcross

So the parental ++ (455+460); ac (470+475)------------------++/ac

Gene order is ------------- ++/ac

+ b c 35----------- recombinant

a + + 33---------- recombinant

+ + c 37------------ recombinant

a b + 35--------------- recombinant

sum of recombinants--------------140

Frequency of recombintion= recombinants/total x100

Map distances between a-c = (140/2000) x 100 = 7 mu

a------------------7 mu -----------------c
