Answer:

1. b) Even when it gets very hot in the summer, the oceans will not dry out.

2. d) The Epipelagic zone,

3. a)Build a small-scale model of a beach to simulate the effects of tsunamis

Explanation:

As the water has a specific heat and a high boiling point the number of changes in its chemical constitution will remain the same even after boiling the ocean water as it does not dry out.

The surface layer of the ocean is known as epipelagic it extends from the surface to 200 meters depth.As this layer has the most visible light as heat form coming from the sun most of the productivity is found in this zone.

As a marine scientist, the best method to study the tsunami would be to make a 3 dimensional model of the surface and hence would save tome and easy to understand.

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
