A test cross was made between true-breeding EEWW flies and eeww flies. The resulting F1 generation was then crossed with eeww fl

ies. 100 offspring in the F2 generation were examined, and it was discovered that the E and W genes were not linked. Which is the correct genotype of the F2 offspring if the genes were linked and if the genes were not linked?

Explanation:

<h3><u>If the genes were linked:</u></h3>

<u>Parental cross: EW/EW X ew/ew</u>

F1 genotype: EW/ew

F1 Gametes:

- Parentals (more abundant): EW and ew

- Recombinant (less abundant): Ew and eW

<u>Test cross: EW/ew X ew/ew</u>

<u>F2 genotypes:</u>

  • Parentals: EW/ew; ew/ew;
  • Recombinant: Ew/ew; eW/ew

<h3><u>If the genes are not linked:</u></h3>

<u>Parental cross: EEWW X eeww</u>

F1 genotype: EeWw

F1 gametes: EW, Ew, eW, ew. Genes assort independently, so all of the possible gametes of the F1 individual will have the same probability.

<u>Test cross: EeWw X eeww</u>

<u>F2 genotypes:</u>

  • 1/4 EeWw, 1/4 Eeww, 1/4 eeWw, 1/4 eeww

The reabsorption of glucose occurs primarily through the walls of the
pantera1 [17]

Options are not provided in the question. The complete question is as following:

The reabsorption of glucose occurs primarily through the walls of the

A. glomerular capsule.

B. nephron loop.

C. proximal convoluted tubule.

D. distal convoluted tubule.

E. renal duct.

Answer:

C. proximal convoluted tubule.

Explanation:

Reabposrtion of glucose is supported by the nephron present in the kidney which mainatain body fluid homeostasis. It maintains extracellular body fluid volume stable  and also maintains the minerals and salts which are essential for body functioning. So, glucose reabsorption is a part of homeostasis.

The process of glucose reabsorption primarily starts through the walls of the  proximal convoluted tubule. proximal convoluted tubule are covered in microvillii and are extensive in length which increases the surface area for absorption. it also contain densly packed mitochndria which provide energy for efficient reabsorption. and then they are tranposrted to proximal straight tuble fo rfurther filteration.

Hence, the correct otpion is C.

PLEASE HELPPPPPPPPPP!!!!!!! Explain how ATP and ADP act as allosteric regulators of enzymes that are responsible for ATP product
lozanna [386]

Answer:

The molecules that bind cellular respiration enzymes act as signals, giving the enzyme information about the cell's energy state. ATP and ADP are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a "stop" signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration.

This is a case of feedback inhibition in which a product feeds back to shut down its pathways.
