Why is it ineffective to treat viral disease with antibiotics? Why is it ineffective to treat viral disease with antibiotics? Pa

thogenic RNA viruses have a high rate of mutation, producing new genetic varieties that are insensitive to antibiotic treatment. Due to excessive antibiotic use, most viruses have evolved to be resistant to antibiotics. Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes.

Answer:

Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes

Explanation:

Viruses can be inhibited by different approaches depending on the type of virus (viruses are classified into DNA or RNA viruses, single or double-stranded viruses, etc).

One of the most commonly used techniques to protect against viral infections is by vaccination

Answer:

Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes

Explanation:

The specificity of the antibiotics to inhibits some  bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition  antibiotics are designed to  have a significant  destructive  effects on  the mechanisms of biochemical reactions in bacteria and its  physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus

goldfiish [28.3K]

Answer: The alleles of a plant that is heterozygous for seed color can be represented as Y for dominant allele for yellow seed and y for recessive allele for green seed.

Explanation: A plant that is heterozygous for seed colour has one dominant allele and one recessive allele for seed colour. If Y represents the dominant allele for yellow seed colour and y represents the recessive allele for green seed colour, therefore the plant has a genotype of Yy. A dominant allele is one that has the ability to mask the effect of a recessive allele while a recessive allele is one whose effect is masked by a dominant allele. Dominant alleles are denoted with upper cases while recessive alleles are denoted with lower cases. A plant that is heterozygous for seed colour with genotype Yy will manifest outwardly as Yellow seed colour due to the presence of the dominant allele Y.

Which joint performs adduction, abduction, horizontal adduction and abduction, medial and lateral rotation, and circumduction?
VLD [36.1K]

Answer:

The ball and socket joint is the one that can perform all those movements.

Explanation:

Ball and socket joint, also know as spheroid joint are types of joints where the part of the bone that articulates with the other bone has a spheroidal shape or ball shape that fits in the depression of the other bone, which means that they are a synovial enarthrosis joint. It has a wide range of movements because it can move in the transverse, vertical, and sagittal axes. An example of this joint is the shoulder, between the scapula and the humerus.

Options:

A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.

B. Reactions that involve enzymes require more energy than reactions without enzymes.

C. The enzyme lactase will slow down the breakdown of lactose in the small intestines.

D. Lactase will require more energy to break down lactose, and less energy is required if it is not present.

Answer:

A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.

Explanation:

A. The enzyme lactase will speed up the breakdown of lactose in the small intestines. - this is true. Lactase is an enzyme that catalyses the breakdown of lactose.  This means it greatly reduces the activation energy required for the breakdown of lactose, and the reaction will happen quicker.

B. Reactions that involve enzymes require more energy than reactions without enzymes. This is false. Reactions that involve enzymes require less energy that reactions without

C. The enzyme lactase will slow down the breakdown of lactose in the small intestines. This is false. It will speed it up

D. Lactase will require more energy to break down lactose, and less energy is required if it is not present.  This is false, more energy is required if it is not present
