In Drosophila, the genes for body coloration and eye size are on different chromosomes. Normal-colored bodies are dominant to eb

Yuri [45]

Answer:

225 flies

Explanation:

Let gene for body colour : A

Let gene for eye type : B

Parent 1 : normal body and normal eyes = AABB

Parent 2: ebony body and eyeless = aabb

F1 : AABB X aabb = AaBb ( all have normal body and normal eye )

F1 progeny is self crossed given that the two genes are on different chromosomes which means they show independent assortment:

AaBb X AaBb =

A_B_ = normal body, normal eyes = 9

aaB_ = ebony body, normal eyes = 3

A_bb = normal body, eyeless = 3

aabb = ebony body, eyeless = 1

Hence the ratio is 9 : 3 : 3 : 1

Out of the 400 flies:

(9/16) * 400 = 225 flies have normal body colour and normal eyes

The picture represents gas exchange in the alveoli. Observe what is happening at location X.

aivan3 [116]

A

CO₂ is the waste product of respiration of cells. Oxygen, on the other hand, is required in cellular respiration. Therefore at the alveolar in the lungs of an organism, CO₂ will be expelled while O₂ will be taken in.

Explanation:

This occurs passively due to the diffusion gradient, CO₂ usually has a higher concentration in the blood and lower concentration in alveoli hence this gas diffuses from the bloodstream into the lungs. On the other hand, oxygen is higher in concentration in the alveoli than in the blood capillaries hence difuses into the blood and taken to the cell for respiration. The CO₂ in the lungs is then expelled through exhalation of the lungs.
