The answer is an envelope.

A virus is an infectious agent that can replicate only inside a host cell. When it is outside the cell, it consists of genetic material coated with protein capsid. Some viruses also have an envelope which covers capsid. The function of the envelope is to identify and bind some receptor sites on the host membranes. After fusing with the cell membrane, it allows to capsid and genetic material to enter the cell and infect it.

ATP is produced via prototrophy, fermentation, and aerobic respiration, and it is used for mechanical, transport, and chemical work.

<h3>Which of the following types of work is powered by the energy produced when ATP is hydrolyzed to ADP and Pi?</h3>

A nucleotide, a sugar with five carbons, and three phosphate groups make up ATP. Phosphoanhydride bonds, which link the phosphates, contain a considerable amount of energy. Cellular work is accomplished using the energy generated by the hydrolysis of ATP into ADP + Pi.

<h3>What are the two mechanisms that, when combined, form oxidative phosphorylation and are connected throughout the ETC?</h3>

The electron transport chain and chemiosmosis are two parts of oxidative phosphorylation that are interdependent. When electrons are transferred from one molecule to another in the electron transport chain, energy is released.

A population of Anolis lizards lives on the mainland. During a storm, three groups of Anolis migrate to three islands, one large
natka813 [3]

Answer:

(i) Small island

(ii) Large island

(iii) Option-3

Explanation:

In the given question, the three population of the Anoles Lizards migrated to three islands of different size.

(i) Genetic drift is a random or by the chance process which changes the frequency of the alleles in the population. The change in the frequency of the allele can be easily observed in the small population therefore the small island with the smallest size of the population will have the strongest genetic drift.

(ii) Heterozygosity of alleles that is with a dominant and a recessive allele is the result of the exchange of alleles in the population. The size of the population is finite on the island therefore the heterozygosity is not introduced in the small population but in a large population, it can be introduced as the mating is random.

(iii) The genetic drift is strongest on the small island therefore L2 allele can be easily influenced by this effect. The selection coefficient is very small that is 0.002 therefore no mutation is occurring on the island.

vredina [299]

Answer:

Impressions of tropical swamp plants were observed on rocks in polar regions. The impressions were dark black imprints, which means the fossils are examples of carbonization, mineralization, and trace fossils.

Explanation:

The fossils tell us that polar regions had tropical plants that could grow in ice,

might have had a different climate in the past, and will have abundance of vegetation.
