Can viruses live through mutation and natural selection

Answers

Answer:

sure why not

Explanation:

as the virus mutates, it may increase, or lessen the chance for the virus to survive a battle against its host. like your regular living organisms (though keep in mind viruses are not considered living), some survive and some die due to natural selection and mutation.

I am pretty sure that the answer is yes since viruses have been around for a long time :))

Action Potential: Relative refractory period
In a neuron, there is a period of time called the absolute refractory period where it is impossible for an action potential to
begin. This corresponds to the change in membrane potential from +30 to -70 mV, or the repolarization phase. Towards the
end of the repolarizing phase, there is a relative refractory period where it is difficult, but not impossible, for another action
potential to begin. Using the time slider function, which of the following segments in the neuron would correspond to a
relative refractory period?

Answers

A second action potential can be triggered during the relative refractory phase, but it will need a stronger stimulus to do so than the first time. Refractory times are brought on by the inactivation gate of the Na+ channel.

What Action Potential related to Relative refractory period?

The axon has a tougher time producing successive action potentials during this time period, which is referred to as the refractory period, as a result of these transient alterations.

As a result, the refractory period restricts the quantity of action potentials that a certain nerve cell can generate in a given amount of action potentials time.

If enough powerful stimuli are applied to the neuron after the absolute refractory time, Na+ channels start to recover from inactivation and the neuron may respond once again by generating action potentials.

Therefore, A stimulus that is stronger than usual is required to generate neuronal activation during the relative refractory period.

Caenorhabditis elegans is a species of soil-dwelling nematode (roundworm) that feeds on soil bacteria, including Bacillus thuringiensis.

a. True
b. False

Answers

Answer:

b. False

Explanation:

Caenorhabditis elegans is a well-known species which is widely used in genetic experiments (i.e., it is a model organism). C. elegans is a soil nematode that eats bacteria, but its survival depends on the ability to distinguish toxic from non-toxic ones. C. elegans cannot feed Bacillus thuringiensis because this bacterium produces a toxin Bt protein that damages its gut, thereby producing the death of this nematode. Interestingly, it has been proposed that Bt toxin pathways might be exploited for the design of new generation nematicides.

Leaves of a healthy potted plant were coated with Vaseline to block stomata. Will this plant remain healthy for long? State three reasons for your answer.​

Answers

➜ If waxy coating is made on the surface of leaf, loss of water in the form of water vapour does not take place. Even the gaseous exchange will not take place. So, photosynthesis will either be reduced or will not take place.

The plant will not remain healthy for long because:

[i] Exchange of gases will not take place.

[ii] Photosynthesis will either be reduced or will not take place due to lack of CO2.

[iii] Transpiration will not take place, so there will be no mechanism of cooling in hot weather.

In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. Basically it's whatever you believe it is.

The University of Illinois has been conducting one of the longest selection experiments, begun in 1896 by C.G. Hopkins. Researchers have been selecting for high corn oil content (as measured in % dry mass). Researchers select those plants with the highest corn oil content, and use only those individuals to seed the next generation. Here is a portion of actual data from their experiment:
1899 mean oil content in entire population: 5.65% dry mass
mean oil content of selected plants: 6.30% dry mass
1900 mean of oil content in entire population: 6.10% dry mass
Calculate the heritability of corn oil content (% dry mass). For full credit, show your work, including any equations used.

Answers

Answer:

0.725

Explanation:

This type of question is a concept of Narrow-sense Heritability and Artificial selection used by plant breeds.

So, heritability = R/S

where;

R = response to selection

S = selection differential

S further implies the difference in mean oil content between base population & selected population.

S = 5.65 - 6.30 = 0.65% ( where the negative sign are not regarded)

R implies the difference in mean oil content between the offspring or population after implementation of selection and the base population.

R = 6.10 - 5.65 = 0.45%

Heritability = R/S = 0.45% / 0.6%

= 0.725

Thus; the heritability in the oil content of corn in the given set of population = 0.725.

The typical human adult uses about 160 g of glucose per day, 120 g of which is used by the brain. The available reserve of glucose (~20 g of circulating glucose and ~190 g of glycogen) is adequate for about one day. After the reserve has been depleted during starvation, what other sources can be used to produce glucose

Answers

Answer:

Fats and proteins that are present in liver, kidneys, and muscles.

Explanation:

When the reserve of glucose is used by the body during starvation, our body uses fats and proteins that are present in liver, kidneys, muscles etc and convert these fats and proteins into glucose. There is high amount of fats and proteins present in our body which can be used when the glucose reserves depleted from the body during starvation so we can conclude that the fats and proteins are the sources that can be used to produce glucose for the body.
