Which of the following is not an enzyme?

Correct Answer: Epiglottis

Explanation:

Epiglottis is that prevents food from entering the windpipe. 

It is a cartilageous flap that flaps opens and closes when swallowing. When you swallow, the epiglottis flattens backward to cover the entrance to your larynx and prevent food from entering the lungs and windpipe. The epiglottis returns to its usual position after swallowing.

 

Correct Answer: 2

Explanation:

In Mitosis, one parent cell divides into 2 daughter cells with identical chromosomal number. However, in Meiosis, one diploid parent cell divides into 4 haploid daughter cells.

Correct Answer: Z discs

Explanation:

A sarcomere is the basic unit of striated muscle tissue. It is the repeating unit between two Z lines.

Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibers or myofibers) which are formed in a process known as myogenesis. Muscle fibers contain numerous tubular myofibrils. Myofibrils are composed of repeating sections of sarcomeres, which appear under the microscope as alternating dark and light bands. Sarcomeres are composed of long, fibrous proteins as filaments that slide past each other when a muscle contracts or relaxes.

 

A muscle fiber from a biceps muscle may contain 100,000 sarcomeres.

Correct Answer: FALSE

Explanation:

No, the given statement is False.

Parasites are organisms that feed on other organisms causing harm to them.

Foods that allow micro organisms to grow are called Growth Mediums.

Correct Answer: FALSE

Explanation:

You cannot see a microorganisms without using a Microscope. You also cannot taste or smell microorganisms such as bacteria in contaminated food.

Correct Answer: 20

Explanation:

Amino acids are a crucial, yet basic unit of protein, and they contain an amino group and a carboxylic group. They play an extensive role in gene expression processes.

 

Amino acids become proteins when 50 or more are bonded together in a chain. All the millions of different proteins in living things are formed by the bonding of only 20 amino acids.

 

Eight of these amino acids are essential and cannot be produced by the body.

They are:

? Leucine

? Isoleucine

? Lysine

? Threonine

? Methionine

? Phenylalanine

? Valine

? Tryptophan

?  Histidine is an amino acid that is categorized as semi-essential since the human body doesn't always need it to properly function

 

Nonessential amino acids are produced by the human body either from essential amino acids or from normal protein breakdowns. Nonessential amino acids include:

? Asparagine

? Alanine

? Arginine

? Aspartic acid

? Cysteine

? Glutamic acid

? Glutamine

? Proline

? Glycine

? Tyrosine

? Serine.

Correct Answer: Uracil

Explanation:

Uracil is present in RNA and binds to adenine whereas thymine is present in DNA and binds to adenine.

Correct Answer: Proteins

Explanation:

Genes which are segment of DNA of a cell contains instructions for assembling proteins.

Correct Answer: Hypertension

Explanation:

he DASH Diet plan was devised to prevent high blood pressure i.e, hypertension.

Correct Answer: Active transport

Explanation:

Active transport is a method of transport of ions or molecules along the cell membrane in the cell from lower to higher concentration region and which needs cellular energy.

There are three main types of Active Transport. They are:

1. The Sodium-Potassium pump,
2. Exocytosis, and
3. Endocytosis.
