Answer:

lipids

Explanation:

Lipase is a type of enzyme that occurs naturally in the digestive system and is responsible for breaking down lipids in foods. The action of lipases in digestion is similar to that of “enzymatic detergents”, converting oils and fats into smaller molecules capable of being absorbed by the body. This catalytic capability is attractive to the cleaning industry because the same process occurs in removing grease from surfaces and fabrics.

These enzymes are obtained by fungal microorganisms in triglyceride media for the development of filamentous fungal colonies. Lipases were initially used in laundry detergents with difficult removal of oils and fats at low temperatures, and the first microorganism in which extraction was done was the fungus Humicola lanuginosa.

What does it mean that a hypothesis must be testable? can a hypothesis be proven unquestionably true? why or why not?

katen-ka-za [31]

A testable hypothesis must be just that--testable. You must be able to provide evidence that your hypothesis can be proven true in order for it to be considered accurate enough for future use among scientists. This can be done through repeated experimentation.

Investigators wish to purify an enzyme—a serine protease—using affinity chromatography. They attach to the matrix of an affinity

Dennis_Churaev [7]

Answer:

After this treatment, the investigators should expect to get a mixture of the desired enzyme, plus fragments of the peptide used to desorb the enzyme in question.

This would be the result of using a peptide as a desorption solution when the desired protein is a protease,

Assuming that the protease retains its activity in the medium in question, and that the peptide can act as a substrate (which would make sense), as the peptide solution is added, it will interact with and bind to the antibody, but some molecules will also interact with the active site of the enzyme as it desorbs and passes through, culminating on the elution of the hydrolized part of the peptide along with the enzyme.

In the family tree below, people with the recessive trait of attached earlobes are shaded gray

serious [3.7K]

<h2><u>Full Question:</u></h2>

In the family tree below, people with the recessive trait of attached earlobes are shaded gray.

What must be true about the person labeled "A"?

A. It is a male with at least one dominant allele.

B. It is a male with two dominant alleles.

C. It is a female with at least one dominant allele.

D. It is a female with two dominant alleles.

<h2><u>Answer:</u></h2>

Its a male with atleast one dominant allele.

Option A.

<h3><u>Explanation:</u></h3>

The gene for the attached earlobe is recessive while the gene for the free earlobes is dominant. In the phylogenetic tree, we can see that both the father and mother aren't having attached earlobes. So both of them are having atleast one dominant allele which makes them have free earlobe.

In the F1 offsprings, one of the female and a male is having free earlobes. So both of them have atleast one dominant allele. The 2nd female is having an attached earlobe. So both the recessive allele have come form one parent each. So both of them are heterozygous.

Thus, the male marked as A atleast have one dominant allele. He can be a homozygous dominant, but the probability is 25%.
