Answer:

The correct answer will be option-A.

Explanation:

Viruses are the pathogenic particles which are composed of proteins called capsid enclosing the genetic material.

The viruses are distinct from the living pathogens as they lack specific cell organelles to perform distinct features as well they lack the living fluid required by the cells called cytoplasm. They also lack replication machinery due to which they largely depend on the hosts.

Thus, option-A is the correct answer.

Answer: A) Viruses lack cytoplasm and organelles

Explanation:

Viruses are composed of DNA and RNA and the protein as the genetic material. Virus is the smallest pathogens and it is different from other pathogen as they cannot reproduced by itself.

Virus lack cytoplasm and organelles that is why they are differ from all the pathogens.

Viruses are composed of genetic material and the proteins and it does not contain lipids.

Therefore, option (A) is correct.

1. which pair of bacteria can be differentiated by oxidase test?

fredd [130]

Answer:

1. A. Pseudomonas and E. coli

2. B. Red without black center

3. B. Salmon/orange

Explanation:

Pseudomonas is referred to as an oxidase positive bacteria while E. Coli is an oxidase negative bacteria. The use of the oxidase test will be helpful in the differentiation of the two Bacteria according to their oxidase activity/properties.

Colonies of Red without black center color is what is expected on HE agar if shigellosis is suspected.

Colonies of Salmon/Orange color is what is expected on HE agar if Enterococcus sp. is suspected.

Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of

natali 33 [55]

The correct option is (a) 2 → 4 → 1 → 3

A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.

<h3>What is genetic variation in population?</h3>

The presence of various alleles, or different gene versions, within a population indicates genetic variety.
If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
