Answer:

D. Chemoautotrophs

Explanation:

Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.

Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.

Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.

Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.

Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.

Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.

Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.

Claim stating what the translated sequence from the DNA sequence is
Stella [2.4K]

First you need to convert the template strand (what you have) to the coding strand.

So using the following guide convert the given letters:

A->T

T->A

G->C

C->G

This will now encode your strand as:

CCTGTAAAAGTGGCA

Break these into three letter chunks:

CCT GTA AAA GTG GCA

Your teacher should either give you a guide or tell you which ones to memorize, but you could also use the following chart to figure out which amino acids will be synthesized:

Use the chart underneath The Genetic Code(DNA) to figure out what matches where.

You will then get the following:

1. Proline (cct)

2. Valine (gta)

3. Lysine (aaa)

4. Valine (gtg)

5. Alanine (gca)

Also remember that if you see a T in your original strand it could also be interpreted as a U. You can always check your answers using this handy online app: http://www.geneseo.edu/~eshamb/php/dna.php

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.
