Answer: A. burning of fossil fuels

Explanation:

The burning of the fossil fuels liberates sulfur dioxide and nitrogen oxide into the atmosphere. In the atmosphere these oxides get mixed with the water vapors which lead to the formation of sulfuric acid and nitric acid in the atmosphere. These acids condense in the form of rain called as acid rain. The acid rain pollute the water, deteriorates the surface of building materials and makes the soil acidic.

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

If a boy exhibits a sex-linked trait that is carried on the X chromosome, what must be true?

Artemon [7]

Answer:

C. His mother carried at least one allele for that trait

Explanation:

-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.

-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.

-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.

Which is a way in which exocytosis differs from the pumping of calcium ions against a concentration gradient?

mr Goodwill [35]

Exocytosis is ana ctive transport method and does not include any transport protein. whereas calcium ions pass through the membrane with the help of trans- membrane protein. These proteins make pores inside hydrophobic membrane and allow the ions to pass though it.
