Based on the images taken through Stella’s microscope, which cell structures could be clearly identified using a compound micros
cestrela7 [59]

Answer:

Use 400 x in order to study the structure clearly.

Explanation:

Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.

) Consider a pea plant- it has a gene controlling seed color- yellow Vs green; another gene controlling seed texture-smooth Vs w
lana [24]

Answer:

Yellow smooth  - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1

Explanation:

Let the green color of the seed be depicted by "G" and the yellow color of the seed be depicted by "g"

Let the smooth the seed be depicted by "R" and wrinkled seed be depicted by "r"

F1 cross -  

true breeding smooth green plant ( RRGG) and true breeding wrinkled yellow (rrgg)

F1 gamete will be RG, RG, rg, rg

F1 offspring will be RrGg , Thus all F1 offspring will be heterozygous smooth and yellow.  

Thus,  R is dominant over r and g is dominant over G

F2 Generation –  

RrGg x RrGg

Gametes will be RG, Rg, rG, rg

RG         Rg          rG           rg

RG RRGG RRGg RrGG RrGg

Rg RRGg RRgg RrGg Rrgg

rG RrGG RrGg rrGG rrGg

rg RrGg Rrgg rrGg rrgg

R is dominant over r and g is dominant over G

Genotypes are –  

RRGG - 1  (Smooth Green)

RRGg-2  (Smooth yellow)

RrGG-2  (Smooth Green)

RrGg-4  (Smooth yellow)

RRgg- 1  (smooth yellow)

Rrgg – 2  (Smooth yellow)

rrGG – 1  (wrinkled Green)

rrGg – 2  (Wrinkled yellow)

rrgg – 1  (wrinkled yellow)

Yellow smooth  - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1

When an athlete is nearing the end of a race ad her cells are low on oxygen?
Artemon [7]
<span>When an athlete is nearing the end of a race and her cells are low on oxygen, it is likely to be fermentation. When cells have used up all their oxygen they ferment glucose into lactic acid. Fermentation is a metabolic process that consumes sugar in the absence of oxygen</span>
