In an enveloped virus, the ___ found in the viral envelope are derived from the host cell whereas the ___ found in the viral envelope are generally virally encoded.

Answers

Answer 1

In an enveloped virus, the glycoproteins found in the viral envelope are derived from the host cell whereas the matrix proteins found in the viral envelope are generally virally encoded.

What is an enveloped virus?

An enveloped virus is a virus that is covered by a lipid envelope that contains glycoproteins. The lipid envelope is a combination of host and viral components that is formed by budding through cellular membranes. The lipid envelope is thought to be derived from host cell membranes in the majority of enveloped viruses, and it is necessary for viral particle transmission, infection, and replication.

The virus's genome is surrounded by a capsid or core structure, which is then surrounded by a protein shell known as the matrix. Finally, the lipid envelope, which is created from the host cell's plasma membrane as the virus buds from it, surrounds it. The enveloped viruses contain matrix proteins and glycoproteins. Matrix proteins and glycoproteins in enveloped viruses are different. Matrix proteins are usually encoded by the virus, while glycoproteins are typically derived from the host cell.

which idea of evolution is supported by the existence of vestigial structures?

Answers

The existence of vestigial structures, which are anatomical features that no longer serve their original purpose, supports the idea of evolution through the process of common descent.

What are vestigial structures?

Vestigial structures are remnants of structures that were once useful to an organism's ancestors but have lost their original function over time as the organism's environment and needs have changed. For example, the wings of flightless birds, such as ostriches, are vestigial structures that no longer serve their original purpose of flight. Similarly, the human appendix is a vestigial structure that no longer plays a significant role in the digestive system.

The existence of vestigial structures provides evidence for evolution through common descent because it suggests that organisms have changed over time, with some structures becoming unnecessary or even harmful as a result of changes in the environment and selective pressures. This supports the idea that all living organisms are related and have evolved from a common ancestor.

Answers

The statement "It favors extremes in traits" is true about disruptive natural selection.

What is Disruptive natural selection?

Disruptive natural selection occurs when extreme traits are favored over intermediate traits, leading to a bimodal distribution of traits in a population. This means that individuals with extreme traits at both ends of the distribution have a higher fitness compared to individuals with intermediate traits. As a result, the population becomes less homogeneous and more specialized in the extreme traits that are favored by natural selection.

What kind of natural selection is disruptive?

Oysters of different colors—dark and light—are one instance of disruptive selection. Oysters with dark or light colours can blend in more effectively. Dark oysters can hide behind the shadow of the rocks, whereas light oysters can blend in with the rocks.

Explain how resting potential is maintained along an axon, the events that lead to an action potential, and the events of an action potential itself

Answers

The depolarizing current causes a burst of electrical activity called an action potential. This indicates that due to an action (stimulus), the resting potential becomes 0 mV.

The sodium/potassium pump uses ATP to transport 3 sodium ions out of the cell and 2 potassium ions into the cell, thus maintaining the resting membrane potential at the axon. This keeps the apparent negative charge of the neuron in place. The sodium-potassium pump sequentially removes three sodium ions from the cell for every two potassium ions introduced.

As such, it retains the significant gradient of potassium ions across the membrane that underlies the resting membrane potential.

how does gene regulation help conserve energy for an organism?

Answers

By selecting expressing genes, expressing genes in the most energy-efficient manner possible, conserving energy during protein synthesis, and responding to feedback mechanisms, gene regulation aids in energy conservation for an organism.

Gene regulationGene regulation enables an organism to only express the genes necessary for a given function, leading to selective gene expression. This prevents the expression of genes that are not necessary, conserving energy that would have been used for their expression.Energy-efficient gene expression: Gene regulation enables an organism to express genes in the way that uses the least amount of energy. For instance, certain genes only express themselves when a certain stimulus, such as a particular dietary or environmental factor, is present. This implies that when the stimulus is not present, the organism does not need to expend energy on expressing these genes.Gene control enables an organism to save energy during protein synthesis, which results in more energy-efficient protein synthesis.

Answers

The neural communication varies greatly from when we are tapped gently on the arm in comparison to when we are slapped across the face. When we slapped that strongly triggers and increases the number of times those neurons fire. But when we tap on the arm that triggers fewer neurons to be fired.

Communication between neurons occurs electrochemically. Neurotransmitter receptors can be found on the dendrites of neighboring neurons. If the impulses from neighboring neurons are strong enough, an action potential will travel the length of the axon to the terminal buttons, releasing neurotransmitters into the synapse in the process.

Many neurotransmitters serve a variety of purposes. Unbalances in a specific neurotransmitter system frequently play a role in psychiatric disorders. As a result, doctors often prescribe psychiatric medications to try to rebalance the neurotransmitters. For a certain neurotransmitter system, drugs can either behave as agonists or antagonists.

how might a scientist determine whether a trait is sex-linked by observing the offspring of several genetic crosses? 4. compare and contrast how is the expression of sex-linked genes both similar to and different from the expression of autosomal genes?

Answers

To determine whether a trait is sex-linked by observing the offspring of several genetic crosses, a scientist may examine the ratio of male and female offspring with and without the trait. If the trait is found to be inherited differently in males and females, then it may be sex-linked.Sex-linked genes differ from autosomal genes in their expression in various ways. Sex-linked genes are located on the sex chromosomes, X and Y. In contrast, autosomal genes are found on the non-sex chromosomes.

Autosomal traits are equally expressed in both males and females, while sex-linked traits are expressed differently in males and females. Males have only one X chromosome and no equivalent Y-linked genes to compensate for gene abnormalities, resulting in males expressing more sex-linked traits than females.

However, sex-linked traits are more likely to be recessive, meaning they will only be expressed if present on both the X chromosomes in females. As a result, males have a higher chance of inheriting and expressing a sex-linked recessive trait than females. Thus, the expression of sex-linked genes is similar to that of autosomal genes in some respects, while it differs in others.
