2) A population of animals is permanently split by a natural barrier into two separate populations in different environments. Wh
kaheart [24]

Answer:

C) The two populations will evolve into separate species.

Explanation:

In the given question, the population of animals has been split into two different populations due to a natural barrier present between them.

When we will observe these species after a very long time, the species will not be able to reproduce with each other and will be reproductively isolated.  This reproductive isolation will lead to the formation of new species but belonging to the same genus.

Thus, Option-C is correct.

Explain how the triplet code of dna is transcribed and translated in the synthesis of proteins
timama [110]
Ok this is going to be a long answer lol


Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). During translation, an mRNA sequence is read using the genetic code, which is a set of rules that defines how an mRNA sequence is to be translated into the 20-letter code of amino acids, which are the building blocks of proteins.



During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA

I hope this helps :)

Differentiate 10sinxcosx​
Harman [31]

Answer:

10\,cos\,2x

Explanation:

To differentiate: 10\,sinx\,\,cos x

Solution:

Use product rule: [f(x)g(x)]'=f'(x)g(x)+f(x)g'(x) and the following formulae:

(sinx)'=cosx\,,\,(cosx)'=-sinx

(10\,sinx\,\,cos x)'=10[(sinx)'cosx+(sinx)(cosx)']\\\\=10[cosx\,cosx-sinx\,sinx]\\\\=10[cos^2x-sin^2x]

Use cos^2x-sin^2x=cos2x

(10\,sinx\,cosx)'=10\,cos2x

Two bacterial strains have the same genes for metabolizing carbohydrates, but one is wild-type for a regulatory inducer while th
klemol [59]

Answer:

b. The two bacterial strains have different phenotypes.

Explanation:

In genetics, the trait that is expressed is often referred to as the dominant trait and it can also be expresssed phenotypically.

Since one of the bacteria produces the inducer, it therefore means that bacteria has the dominant strain for the regulatory inducer while the other bacteria might have the strain but since it is not expressed phenotypically, it is as a result not dominant.

Phenotype refers to the physical appearance of an organism as a result of the interaction of its genes with the environment. Examples of phenotypic expresssions are hair colour, skin colour, height, etc.
