Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.
This method of natural selectionthat the fantastic alleles of this variation organism are surpassed directly to offspring, the system of natural selection results in evolution occurring.
What is natural selection?Natural selection is the system thru which populations of residing organisms adapt and extrade. Individuals in a populace are evidently variable, which means that they're all one of a kind in a few ways.
Natural selection is a mechanism of evolution as there are. Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation. Natural selection is a system in which organisms can be higher tailored to their surroundings will live to tell the tale and reproduce.

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.

Which table correctly describes the functions of the cell structures
listed
HELP ME PLEASE
Answer:
The correct answer is - cell membrane - regulates cell contents.
Explanation:
Various cell structures have different cellular functions in the cells. The major function of the chloroplast is to produce sugar with the help of chlorophyll pigment by trapping the sunlight. The mitochondria perform cellular respiration and convert sugar to energy.
The vacuoles are the cell structure that helps in maintaining water balance and also store nutrients and sometimes help in waste disposal, however, it is not its major function. The cell membrane is the cellular structure and barrier that regulate what cell content will move outside the cell and what will enter.
does cellular respiration produced or consumed food?
Answer:
I guess it consumes food.
Explanation:
because cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions.

Looking at the overall structure of the catkins, how do you
think these trees evolved to have their pollen disperse?
Answer: just look it up on goegle
Explanation:
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.

Describe how each of Newton’s laws may be observable during a car trip.
If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest. Additionally, if a car was moving straight when another car struck it, the direction of the car would shift.
What are newton's three law of motions ?According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
There's a fourth law , it states that every object tends to remain in the state it is in right now. We refer to this propensity as inertia. Every object tends to remain in the state it is in right now.
Therefore, If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest (First law) . Additionally, if a car was moving straight when another car struck it, the direction of the car would shift (Third law).

Explain why harmful mutations tend to disappear, while beneficial mutations become
widespread.
Answer:
Harmful mutations don't accumulate over time because they reduce the reproductive success of an organism! These mutations would be dead before they can produce any offspring, so there's a slim chance of their genes being passed on. (So it's basically like survival of the fittest, the ones that survive usually have beneficial mutations because that's what keeps them alive lol) Beneficial mutations play a big role in evolution too!

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.

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.

Humans produce the enzyme amylase. This enzyme breaks down starch, a
complex carbohydrate found in many food sources (e.g. potatoes, breads).
Explain why the human digestive system is unable to use amylase to break down
the complex carbohydrate cellulose, which is also found in some foods (such as
celery).
Explanation:
We lack the enzyme cellulase which is the enzyme required to break down cellulose.
Base on the given information, human can produce the enzyme amylase, but cannot produce the appropriate enzymes that is able to breakdown the beta acetal linkages that exist in cellulose.
Enzymes serves as biological protein, and it is needed in the body to carry out specific functions.
Human posses amylase which made it possible to breaks down starch that is contained in many carbohydrate food that we eat.
We can conclude that human doesn't have the enzymes that that act on complex cellulose contain in found like celery.
