Which of the following does NOT contribute to genetic variation among plants?

Biology
1 answer:
egoroff_w [7]3 years ago
6 0

Answer:

The correct answer will be option-A.

Explanation:

Genetic variation is the difference in the DNA sequences of individuals in a population. Genetic recombination is the main reason for the diversity of organism on earth.

The genetic variation takes place during gamete formation by recombination of DNA sequences which takes place during prophase of meiosis I.

Since genetic variation involves changes in the coding segments of the DNA called genes which leads to mutations, therefore, flowering time does not influence the genetic variation and option-A is the correct answer

List in order the various fluid compartments that a glucose molecule would encounter beginning with absorption from the lumen of
Zinaida [17]

Answer:

The correct list of compartments glucose enter is :

The lumen > plasma (extracellular fluid) > interstitial fluid (extracellular fluid) >   the skeletal muscle cell (intracellular fluid)

Explanation:

The glucose molecule would start from the lumen of the intestine where is absorbed. The glucose enters the plasma a part of the circulatory system known as extracellular fluid.

The glucose also encounters another type of extracellular fluid the interstitial fluid that is not in the circulatory system. At the last glucose as it is entering the skeletal muscle cell the last fluid compartment, which is intracellular fluid. This fluid is inside the cells.

Using the ultrasonication and agitation method of liposome preparation, what concentration of lipid is necessary to prepare lipo
Galina-37 [17]

The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

<h3>What are liposomes?</h3>

Liposomes are vesicles which are made up of a lipid bilayer membrane.

Liposomes are important as delivery vehicles for substances such as drugs.

Ultrasonication is a method of liposomes preparation.

Solution of liposomes is dependent on the size.

The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.

Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

Ilya [14]

Answer: His genes contain a mutation that prevents red blood cells from proper functioning.

Explanation:

Hereditary anaemia is a type of disorder that are genetically transmitted to the offsprings by the parents . These type of anaemia are inherited from the parent including sickle cell anaemia.

The offsprings inherent Gene mutation that cause abnormalitiies. They inherit abnormal haemoglobin that can reduce the life span of red blood cells thereby affecting their proper functioning of carrying oxygen in the blood, leading to anaemia.
