why is tetracycline selectively toxic against bacteria Eukaryotic cells will enzymatically destroy the drug. Eukaryotic cells wi

ll actively pump the drug out of their interiors. The drug affects peptidoglycan synthesis, and eukaryotic cells have no peptidoglycan. The drug binds to the 30S small ribosomal subunit — eukaryotes have a 40S small subunit. Eukaryotes lack a small ribosomal subunit, so the drug cannot negatively affect them.

Answer:

The correct answer is The drug binds to the 30S small ribosomal  subunit eukaryotes have 40S small sub unit.

Explanation:

Tetracycline belongs to broad spectrum antibiotic.Tetracycline is named so because it contain a derivative of four hydrocarbon rings.

 Tetracycline act by inhibiting the protein synthesis process in prokatotes by binding to the small ribosomal subunit also called 30S subsunit and blocks the binding of amino acyl tRNA to the A site or attachment site of ribosome.

 As eukaryotes contain 40S ribosomal  subunit,it becomes difficult for tetracycline to bind with 40S ribosomal subunit of eukaryotes.

kherson [118]

Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Gene dosage is modified is a major contributor to this phenomenon.

In the field of genetics, we can define gene dosage as the quantitative measure or copies of a particular gene that is present in an organism. Abnormalities in the gene dosage at a particular location can cause severe damage to the resulting phenotype.

Gene dosage can lead to chromosome duplications if the copy number or gene product is more and it can cause deletions if the copy number or gene product is less. Such complications will result in abnormal phenotypes or inviable gametes. For example, in Down's syndrome, the person has a modification of the 21st chromosome as there is one extra 21st chromosome present. This leads to a variety of diseases and defects in the person.

Although a part of your question is missing, you might be referring to this question:

Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Which factor is a major contributor to this phenomenon?

a. Recessive diseases are unmasked by additional copies.

b. The genes are found in a novel arrangement.

c. Gene dosage is modified.

What is the process by which substances move from areas of higher concentration to areas of lower concentration
AleksandrR [38]

Answer:

Diffusion

Explanation:

The process by which substances move from areas of higher concentration to areas of lower concentration is called diffusion.

For example:

Substance moves across a cell membrane without using the cell's energy tends to move away from the area where it is more concentrated.

It is known as passive transport.

It is the process in which substance without using the cellular energy tend to move down the concentration gradient.

It is also known as simple diffusion.

When perfume bottle is open particles spread in air due to difference in concentration from bottle to out side environment.

While,

In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.

This process require energy.
