The correct answer is option A

Plants performs both the functions photosynthesis and cellular respiration.The waste product of photosynthesis is oxygen that the plant releases in the environment.

Plants also performs cellular respiration and in the process of cellular respiration the waste product is carbon dioxide.

Hence, the waste products are carbon dioxide and oxygen.

Which of the following is/are true?

dem82 [27]

Answer: option B) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population

Explanation:

Sympatric speciation is an event/situation whereby organisms of the same species:

- live in the same territory or nearby territories ( i.e do not live in geographical isolation)

- DO NOT interbreed, but select a sexual mate from a much diverse territory to yield new species or offsprings.

This sexual selection then results in generations of offsprings that are genetically different from the rest of the same species due to uneven gene flow or disruption of alleles among the population of same species.

Thus, only option B is true.

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
