Answer:

Explanation:

Psychrophile is a type of organism and bacteria that can grow and reproduce in very low temperatures. Besides low and cold temperatures these organisms adapt to high pressure and high concentrations of salt. Their body has adapted to these types of harsh environments by having a body that keeps them from freezing. Their enzymes had evolved to engage in activities such as activity-stability-flexibility as a method for adapting to the cold. This type of bacteria can grow in refrigerated temperatures and they could be found in foods and dairy products.

Alex_Xolod [135]

Options are not provided in the question. The complete question is as following:

A researcher has performed a BLASTp search for a protein of interest. He identifies a globular protein that shares 30 percent of its amino acid sequence and positioning with his target protein. What can he conclude about the shape of his protein of interest?

a) It is also a globular protein.

b) It is a fibrous protein.

c) It has only a primary structure.

d) It demonstrates only pleated sheets as part of its structure.  

e) The researcher can conclude nothing about his protein of interest.

Answer:

a) It is also a globular protein.

Explanation:

Globular proteins are one of the common form of protein  (the other are fibrous, disordered, and membrane proteins) having spherical shape.

Protein-protein BLAST (blastp), This software returns the most related sequences of protein from the protein database defined by the user, provided a protein query.

So, the blastp has searched for globular protein.

Hence, the correct option is a.

2. Meiosis 2.

3. End.

4A. The chromosome theory of inheritance states that chromosomes are the main carriers of the genetic factors responsible for inheritance.

B. Body cells have two sets of chromosomes while sex cells have one set. Therefore, when two sex cells meet, they form an embryo with two copies of each chromosomes thereby producing a body cell with the exact number of chromosomes. In essence, meiosis maintains the right number of chromosomes of body cells by creating half the number of chromosomes of sex cells.

C. Meiosis.

An enzyme _____. is an organic catalyst is a inorganic catalyst can bind to nearly any molecule is a source of energy for enderg
Sidana [21]

An enzyme is an organic catalyst.

<h3>What is an enzyme?</h3>

Enzymes are proteins that help speed up metabolism or the chemical reactions in our bodies.

They build some substances and break others down.

All living things have enzymes. Our bodies naturally produce enzymes.

But enzymes are also in manufactured products and food.

Examples of specific enzymes:

Amylase: In the saliva, amylase helps change starches into sugars.

Maltase: This also occurs in the saliva, and breaks the sugar maltose into glucose.

Trypsin: These enzymes break proteins down into amino acids in the small intestine.

ipn [44]
It is only active at a pH of around 2 because that is around the same pH as the gastric juices in the stomach which is where pepsin is used to break down proteins.
