Which method did Morgan and colleagues use to show that hereditary information was carried on chromosomes?

Biology
1 answer:
prohojiy [21]2 years ago
3 0

Answer:

correlations between microscopic observations of chromosomal movement and the characteristics of offspring

Explanation:

Morgan and his colleagues carried out genetic experiments on fruit fly, <em>Drosophila melanogaster. </em>They observed the movement of chromosomes of the fruit fly during cell division with the help of the microscope and analyzed the resultant phenotypes.

These correlations between chromosomal movement during cell division and specific phenotypes led to the chromosomal theory of inheritance which states that chromosomes are the carrier of genetic information from one generation to next.

A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds
SVETLANKA909090 [29]

Answer:

The amount of light they receive.

Explanation:

In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.

Amylase is an enzyme that converts carbohydrate polymers into monomers. Glycogen synthase is one of the enzymes involved in conv
ollegr [7]

Answer:

This question is incomplete; the complete part is:

Which of the following best explains the reactions of these enzymes?

A) Amylase aids in the removal of a water molecule to break covalent bonds whereas glycogen synthase aids in the addition of a water molecule to form covalent bonds.

B) Amylase aids in the addition of a water molecule to break covalent bonds whereas glycogen synthase aids in the removal of a water molecule to form covalent bonds.

C) Amylase aids in the addition of a water molecule to form covalent bonds whereas glycogen synthase aids in the removal of a water molecule to break covalent bonds.

D) Amylase aids in the removal of a water molecule to form covalent bonds whereas glycogen synthase aids in the addition of a water molecule to break covalent bonds.

The answer is A

Explanation:

In nature, MONOMERS are simpler units that come together to form larger units called POLYMERS. According to this question, Amylase converts carbohydrate polymers to monomers while Glycogen synthase converts carbohydrate monomers to polymers.

Monomers of carbohydrate are joined together by adding water molecule to form covalent bonds between the monomer units, hence, forming a POLYMER. This is how Glycogen synthase catalyzes its reaction of forming carbohydrate polymer (glycogen).

On the other hand, Amylase breaks down large polymer molecules into monomers by removing water molecules in a process called HYDROLYSIS. This breaks the covalent bond that holds the monomeric units together.

The process of protein denaturation Multiple Choice: a) is only possible in proteins with quaternary structure. b) is permanent
pav-90 [236]

Answer:

The correct option is D.

Explanation:

Protein generally are very sensitive macro molecules; they have specific temperatures and pH that are ideal for their operations, this is especially true for proteins that act as enzymes in biochemical reactions.

There are four different types of structures that a protein can assume, these are primary, secondary, tertiary and Quaternary structure. The structure of a protein determines the kind of function it can perform.

There are some factors that can destroy the structure and functions of proteins, these include excessive heat and pH. A protein is said to be denatured when its secondary and tertiary structure have been disrupted or destroyed. Denaturation does not affect the primary structure of the protein, thus, the peptide bond remains intact.

Denaturation is usually temporary and can be reversed if the factors that cause denaturation is removed, this process is called RENATURATION. Renaturation process allow the protein to refold and resume its functions.  But sometimes,  denaturation  can be permanent and irreversible leading to permanent loss of protein functions.
