Answer:

The answer is C) They appear to be the molecular carriers of coded hereditary information.

Explanation:

Why NOT C) They appear to be the molecular carriers of coded hereditary information?

This is the job of the nucleic acids. It is composed of nucleotides which are the basic units of DNA and RNA. They carry genetic information about a certain organism.

<h3 /><h3>True of proteins:</h3>

A) They may be denatured or coagulated by heat or acidity.

Denaturation is the destruction of the protein's secondary and/or tertiary structures. The primary structure is not disrupted due to the tough peptide bonds and can only be broken down by acid. For heat denaturation, hydrogen bonds are destroyed, as in cooking of egg whites and medical equipment sterilization.

B) They have both functional and structural roles in the body.

There are many kinds of proteins that have functional and structural roles like hormones (FSH, LH), antibodies (IgA, IgM), enzymes (lipase, amylase), for storage/transport (hemoglobin, ferritin), and locomotion (actin, troponin).

D) Their function depends on their three-dimensional shape.

Just like hemoglobin, it's quaternary structure can carry 4 molecules of iron in one go. Enzymes are shaped accordingly to fit a specific substrate (lock-and-key model)

N a jungle habitat, there lives a species of snake, called Species A. The carrying capacity of the jungle allows 5000 of Species

OLEGan [10]

Based on the carrying capacity of the habitat and the changes that occurred in number of the two snake species, correct option is They occupy the same niche and are competing fully for all resources; option D

<h3>What is carrying capacity of a habitat?</h3>

The carrying capacity of a habitat is the maximum number of species the available resources in that habitat can sustain.

The data given of the species of snakes, Species A and Species B, indicate that they are both present in the habitat after a change occurs in the habitat.

Since the population of Species A became zero after Species B was introduced in the habitat, they occupy the same niche and are competing fully for all resources.

In conclusion, the competition between the species of snakes is responsible for the decline in Species A.

How cellular respiration relates to law of thermodynamics???

Butoxors [25]

Answer:

First Law of Thermodynamics in Biological Systems

All biological organisms require energy to survive. ... The chemical energy is stored in the form of glucose, which is used to form complex carbohydrates necessary to build plant mass. The energy stored in glucose can also be released through cellular respiration.
