The fly species in the scenario is most likely demonstrating sympatric speciation due to their preference for either cherry or apple.
Sympatric speciation occurs when two or more populations of a species live in the same geographic area but evolve into distinct species due to differences in their ecological or behavioral preferences.
In this case, the flies that lay eggs on cherries and the flies that lay eggs on apples have different ecological preferences, and they prefer to mate with their own type. This can result in reproductive isolation and the evolution of two distinct species, even though they live in the same geographic area.
Allopatric speciation, on the other hand, occurs when two or more populations of a species are geographically isolated from each other, and they evolve into distinct species due to genetic drift, natural selection, or other factors. This scenario does not involve geographic isolation, so it is not an example of allopatric speciation.

Elizabeth IS not a carrier for the trait.
Tatiana carried the recessive allele.
Her brother has
hemophilia and her sister is a carrier.
Two of her sons have hemophilia and one does not.
The best evidence would be two of her sons having hemophilia while one does not.
HemophiliaHemophilia is a sex-linked recessive disorder. This means that females can be homzygous normal, heterozygous, or affected by the disorder while males can either be normal or affected.
Why? This is because males have only one X chromosome (XY) while females have 2 X chromosomes (XX).
Also, the X chromosomes in males are always from their mothers while their Y chromosomes come from the father.
So, if the two X chromosomes of Irene are normal for hemophilia, none of her sons should be affected. If the two X chromosomes are affected, all her sons will have the disorders.
When one X chromosome is affected and the other is normal, it means that some of her sons will inherit the affected chromosome and have the disorder while some will inherit the normal chromosome and will be free from hemophilia.

Because hemophilia is an X-linked recessive disorder, the X chromosome plays a role in its genesis. Males only have one X and one Y chromosome, whereas females have two X chromosomes.
If Irene were homozygous for the normal allele (non-carrier), none of her boys would receive an incorrect X chromosome, preventing them from developing hemophilia. If Irene were homozygous for the hemophilia allele (affected), all of her sons would be affected by the disease since they would inherit her X chromosome.
However, Irene may be a carrier of the hemophilia allele given that two of her sons have the condition while one does not. As a transporter, she has one typical X chromosome and one X chromosome conveying the hemophilia allele.

Which statement BEST describes how greenhouse gasses act as natural insulators in the Earth's system?
Hi there, your answer is below.
The gases absorb and emit a part of the heat reflected by the Earth's surface.
Solar radiation will pass through the atmosphere first in the greenhouse effect. Some of them will get through and touch the surface of the planet. Long-wave thermal radiation, which is what the greenhouse gases will absorb, will be produced when some of the energy that strikes the Earth's surface is transformed. They are returned to the Earth via greenhouse gases.
What are greenhouse gases, and why do they affect our environment?The surface of the Earth would be much colder and have a "snowball Earth" if it weren't for the impact of greenhouse gases, primarily water vapor, carbon dioxide, and methane.
Because the greenhouse gases are generally transparent to the sun's incoming radiation, which is mostly in the visible light region of the spectrum, the greenhouse effect is able to take place. In contrast, the majority of the radiation that the Earth emits is in the infrared region of the spectrum, which is absorbed by greenhouse gases. Some of the radiation from these gases is redirected to the earth when it is later released. This traps it, warming the planet's surface in the process. The average temperature of the Earth would be -14 degrees Celsius without greenhouse gases.
Greenhouse gases have acted to even out temperature changes over Earth's history. Huge woods have thrived when the Earth experienced warmer times, as the Carboniferous epoch. These have taken in carbon dioxide from the air, storing the resultant carbon in the form of coal deposits underground. After a certain amount of carbon has been stored, the atmospheric concentration of carbon dioxide falls to very low levels, and the warming effect is eliminated. The trees perish as the globe cools. Currently, plants are no longer removing carbon dioxide from the atmosphere, while volcanoes are still adding carbon dioxide to the atmosphere. The increase in carbon dioxide causes a rise in global warming. We are now recuperating from the last glacier, which ended roughly 10,000 years ago, during a mild time. In the past 120,000 years, the previous warm era peaked.
The ability of carbon dioxide to boost plant development is another crucial effect. Without the impact of the increased carbon dioxide concentration on crops, it is improbable that the Earth could support the 7 billion people that inhabit it now.
The amount of carbon stored in the atmosphere is rather tiny. There are currently 800 billion tons of carbon in it. But only approximately a quarter of this, or 210 billion tons, of the carbon gets recycled each year by plants and the seas. Consequently, the two-year half life of carbon in the atmosphere is rather short. Because there is such a tiny atmospheric carbon storage, people have a significant impact. Burning fossil fuels only adds roughly 9 billion tons annually. But throughout my lifetime, the concentration has increased by 30%, from around 300 parts per million in 1947 to 410 parts per million now, as a result of this modest increment each year. As a result, there has been a little but considerable increase in surface temperature as well as rising sea levels due to ice cap melting. Although the increase in sea levels over the past 70 years has only been around 9 inches, it is rising, and because so many people live near the coasts, we are susceptible.
Because the atmospheric carbon storage is so limited, it is possible to lower atmospheric carbon and prevent flooding in our coastal communities, for example by fertilizing the seas to improve their capacity to absorb carbon dioxide.

Eddie

The effect of sympathetic nervous system stimulation on the heart is to increase heart rate and myocardial contractility.
In the sympathetic nervous system (SNS), as the sympathetic stimulation increases, the heart rate also decreases along with the force of contraction.
The heart rate increases because of the release of hormones catecholamines - epinephrine and norepinephrine whereas the force of contraction increases because of a higher end-systolic volume [ESV] which requires a forceful heart contraction to pump more blood out of the ventricle which will decrease the ESV value.
