All carbohydrates are made up of monosaccharides.

Explanation:

The carbohydrates are one of the crucial naturally occurring chemicals when it comes to the survival and prosperity of the living organisms. They serve lot of different roles, from providing energy, storing energy, fertilization, make up the RNA, strengthening the immune system etc.

The carbohydrates though are not all the same, and they can actually be divided into four different groups:

monosaccharides
disaccharides
oligosaccharides
polysaccharides

Each of them has different chemical composition, thus having different properties. Those different properties in turn result in different types of usages for each of them among the living organisms. The smallest units, the monosaccharides and disaccharides are actually the ones that are referred to as sugars, something that we all know very well and use it on daily basis.

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?

Zinaida [17]

Answer:

Base substitution mutation

Explanation:

Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:

ATCGGCTTAACG to ATCGGCTAAACG

This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.

Which of the following does NOT characterize proteins?

8090 [49]

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)

A student explains the formation of the planetary system as follows.

Galina-37 [17]

A. The nebula contracts and shrinks instead of expanding

Nebula is the cloud of interstellar dust and gas that forms a star. It is collborately shaped during colliding and collapsing of the interstellar mediums this is influenced by the gravitational attraction of the atoms and particles in the entites. Hence, there are three types of nebular namely, are classical nebula, diffuse nebula, planetary nebular and supernova remnants.
