Explanation:
Know how to calculate the amount of chromosomes in mitotic cells and in gamete cells, when given an amount of the chromosome number for one of the two types of cells. For example, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, how many chromosomes will be in each egg cell?
Answer:
4 chromosomes
Explanation:
Meiosis is a kind of cell division that produces daughter cells that already have their chromosome number reduced by half. Due to this reason, meiosis is called a reduction division. A diploid parent cell (2n) will produce gametes with haploid cells (n).
According to this question, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, after undergoing meiotic division, it will possess 4 chromosomes in each gamete cell. Note that the chromosome number has been reduced by half.

Considering the most important ecological issue of the future, what is the biggest challenge the world will face in its dedication to conservation and restoration in the future?
The number of species in an extinction vortex
Spread of disease and parasites via corridors
The amount of land and energy resources
The pressures of its growing population
Answer:
its the amount of land and energy resources or the pressure of its growing population.
Explanation:
It is likely that the biggest challenge the world will face in its dedication to conservation and restoration in the future will be the pressures of its growing population, which is the last option.
What is population growth?As the population grows, there will be an increased demand for food, water, energy, and land, which will lead to habitat loss, deforestation, pollution, and climate change. These factors can exacerbate other ecological issues, such as the number of species in an extinction vortex and the spread of disease and parasites via corridors. Therefore, it is crucial to address the root cause of these problems by promoting sustainable practices and reducing our impact on the environment.
Hence, it is likely that the biggest challenge the world will face in its dedication to conservation and restoration in the future will be the pressures of its growing population, which is the last option.

Two frog populations (same species) living in two neighboring lakes sing slightly different courtship songs. Increased irrigation makes the land between the two lakes wetter, allowing frogs to expand their ranges to the area between the lakes. Females in both populations prefer loud frogs to quieter frogs but do not distinguish between the two slightly different songs. Assuming that courtship song differences have a genetic basis, predict what will likely happen to the songs of the two frog populations.
A. You cannot predict a change in the courtship songs at the two lakes.
B. Disruptive selection will cause the songs to differentiate even more.
C. The songs will become more similar to each other.
D. Males will become louder.
E. Genetic drift will cause the songs to differentiate even more.
Answer:
C. The songs will become more similar to each other.
Explanation:
To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.
One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.
So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.
The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.

NASA scientists use satellites to monitor two important factors that lead too landslides
Answer:
The most important factors that lead to landslides are the declivity of the terrain and the type of soil.
Explanation:
Stony soils are more prone to landslides, especially on steep terrain and without any type of vegetation cover. During heavy rainfall, these two factors can promote landslides that cause major disasters, as water is able to drag this soil violently. To prevent this from happening and people from being harmed, NASA has developed satellites, which capture rainfall data and monitor the slope and composition of soils, being able to see in advance areas that could be landslides. In this way, it is possible to develop strategies that prevent the landslide from happening.

variation in a population exists
Answer:
variation in a population exists
Explanation:
Variation is present in a population of antelopes so due to this variation, the predator such as lion can catch the slowest antelope that is present in the population while on the other hand, the faster antelopes can save their lives by running very fast. Variation is present in a population of antelopes due to availability of food as well as genetic characteristics. These variation leads to the availability of food to the lions.

1. A cool piece of iron gets warm when a red-hot piece of iron is placed a few inches
away. How is heat transferred in this scenario?
Answer:
Convection currents in the air between the pieces of metal transfer all the heat. The air between the two pieces of iron emits thermal radiation that is absorbed by the cool iron.
There you go, hope this helped.
Heat energy is transferred from one matter to another through various modes and methods. A cool iron piece heats due to convection that transferred the heat from the hot iron.
What is convection?Convection has been one of the modes of thermal heat transformation that uses matter to transfer the heat from higher to lower concentrations, unlike the radiation mode. The matter particles move from hot to lower temperatures.
The air present between the cold and hot iron piece acts as the medium by which the cold iron piece absorbs the heat transferred by the hot iron piece. This thermal energy is emitted and absorbed due to the difference in temperature.
Therefore, the process of convection facilitates the thermal heat transformation from hot to cold iron objects.

Explain how and why you would conduct a study to determine if this bone can be used to determine sex
Answer:
The pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably. Males have a square jawline and the line between the outer edge of the jaw and the ear is vertical. Conversely, in females the jaw is much more pointed and the edge of the jaw slopes gently towards the ear.

Why is ocean acidification dangerous?2-3 complete sentences
Answer:
Carbonate is important to marine life, especially those with exoskeletons and shells, who form their protective casings from carbonate. Ocean acidification reduces the amount of available carbonate, and can cause their shells to crumble and dissolve. Animals then have to spend extra energy either repairing their shells or thickening them to survive.

Track the evolutionary path of a butterfly and comment on it.
Answer:
The colorful canvas of the butterfly wing is an example of evolutionary innovation and adaptation. Compared with their ansestors, whose wings wore patterns of black, brown, and gray, the Lepidoptera (butterflies and moths) evolved a more varied palette of pigmentation.
I think it is very cool that they were able to evolve. For example, some butterflies use their bright colors to trick preators into thinking they are poisonous. The early butterflies could not do this.
Explanation:
