Answer:

The gene for the protein is turned on and off at different times.

Explanation:

The turning on and off of the gene is described as gene regulation. This process is important because it enables the cells to react quickly to the changes in the environment.

Note that , this process mostly occur at transcription level during gene expression , and help in determining the amount of protein made by a gene.

If took 3.5 hours for a train to travel the distance between two cities at a velocity of 120km/h. How far did the train travel b

Andrew [12]

Given:
Time: 3.5 hrs
Velocity: 120 miles/hour
Now Distance= Speed x Time
Now Velocity and Speed have the same magnitude. Velocity being a vector quantity has a definite direction. Where as speed is a scalar quantity, it indicates only the magnitude and doesn’t define any direction.
Hence Distance= Velocity x Time
Distance= 3.5x20=420 miles

Which of the following is a plant adaptation to living in a cold climate?

NemiM [27]

Answer:

b. Vernalization

Explanation:

Vernalization is a phenomenon in which plants require low temperature for the flowering. There is either qualitatively or quantitatively dependent on exposure to very low temperature. This process is known as vernalization. Vernalization defines especially to the promotion of flowering by a period of low climate. For example; Vernalisation occurs in biennial plants. Biennials are monocarpic plants which normally flower and may die in the second season. Some common examples of biennials are carrots, Sugarbeet, cabbages, etc.

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)
