Answer:

Question is incomplete.

the full question is  as follow

In the three-domain model, the bacterial ancestor of mitochondria derives from ancient ________, where as chloroplasts derive from ancient _____.

Explanation:

A review article is published in journal of cell science in 2016, in which they reveled the bacterial hierarchy how bacteria came into existence.  According to this paper and its references In the three-domain model, the bacterial ancestor of mitochondria derives from ancient ___proteobacteria___, where as chloroplasts derive from ancient ___cyanobacteria___.

Reference: Dacks, Joel B., et al. "The changing view of eukaryogenesis–fossils, cells, lineages and how they all come together." J Cell Sci 129.20 (2016): 3695-3703.

A gene has 2 alleles, R & B, List the possible genotypes? I also need help with questions 5, 6, 7 and 8 please help! Pls loo
irakobra [83]

Answer:

5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)

6.) Frequency of R: 0.5

7.)Frequency of R: 0.5

8.)Frequency of R: 0.375

Explanation:

5.) If R and B code for the different forms of the same protein then they are only a few possible out comes

6.) First calculate the total alleles in population

allele R= 40

Allele B=40

total allele = R+B= 40+40

=80

Now to find allele R frequency is:

(Total R alleles) / (Total allele in pop)

40/80=

0.5

7.)Calculate the total alleles

Alleles from for R

RR= 10

R=10x 2= 20

Multiply the value by 2 because there are 2 R alleles present in

RB=20

R=20

Number doesn't change there is only 1 R allele

Total R=20+20

=40

Alleles For B

BB=10

B=10×2

=20

Same thing here, two B alleles together so multiple by 2

RB=20

B=20

Total B= 20+20

=40

Total alleles in pop add

40+40

=80

Frequency of R

Total of R/Total Alleles

=40/80

=0.5

8.)Repeat the same thing in 7 but use different numbers

RR=10

R=10x2

=20

RB=10

R=10

Total R= 20+10

=30

Which of the following is not important in determining the distribution of organisms in aquatic biomes? A. light penetration B.
Vlada [557]

Answer: Option C) water

Explanation:

The factors affecting the distribution of organisms in aquatic biomes include:

- Light penetration: Plants life is limited to the upper layers of the ocean where light cab penetrate and be used to produce food. Thus, very few organisms are found in the ocean deep.

- Waves: the movement of surface water of the oceans, and it's direction affect the placement of organisms as they must have strong anchor or body parts suited for buoyancy

- salinity: not all organisms can survive in water with high salt content. Thus, some live in salty water, and others in fresh water or the mixture.

- Mineral content: the levels of hydrogen ion could make a water bidy alkaline or acidic thus affecting organism that can survive in it

Thus, since water ordinarilly is Universal, it is not an important factor in determining distribution of organisms in aquatic biomes
