Answer:

DNA transcription creates mRNA. Transcription is when information in a strand of DNA is replicated or copied into a new strand of mRNA. The DNA sequence serves as a template for mRNA to be synthesized in the nucleus. mRNA is catalyzed by the enzyme RNA polymerase and requires nucleotide triphosphates as substrates in order to initiate and sustain DNA synthesis.

Hope that helps.

nydimaria [60]

The answer is copper. Nonrenewable resources are those that cannot be readily/naturally replaced at rates that match those of consumption (an aspect that allow renewable resources to be sustainable). Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.

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

Tertiary consumers are at the top of the food chain, and eat secondary consumers and primary consumers. Primary producers are energy producing things like plants, etc.

In-s [12.5K]

Answer:

c.The addition of a water molecule breaks a bond between sugar mono-mers.

Explanation:

Hydrolysis refers to reaction with water. When water molecules are added to carbohydrates, the bonds between the sugar monomers are broken. This is the chemical reaction known as hydrolysis reaction.

Generally, since carbohydrates are polymers we can say that hydrolysis reactions result in the breakdown of carbohydrate polymers into sugar monomers by using water molecules
