Imagine a population of moths. White moths are easier for birds to see and eat. Black moths blend into their surroundings, so they are less visible to birds than white moths. As a result, black moths are more likely to survive and reproduce, enabling the gene for black coloration to be passed on to the next generation. This increases the frequency of genes for black coloration in the population. Which evolutionary process does this scenario describe

Answers

Answer:

The correct answer is - natural selection.

Explanation:

Natural selection is a process of adapting according to the environmental change in order to survive and reproduce and increase their number. It is represented by Darwin for the first time. Natural selection leads to evolution.

In this case, White moths adapt according to the environment by increasing the population of black moths in order to blend with the surrounding and as the result, black moths are more likely to produce and survive and passed this trait to the next generation.

Which description explains why there are two high and two low tides in a day? (4 points)

Earth moves closer to the sun and moon twice a day.

Earth revolves around the tidal bulges created by gravitational forces.

Earth rotates in and out of a tidal bulge twice a day.

The moon's gravity increases over the oceans and decreases over the land.

Answers

Answer:

Earth rotates in and out of a tidal bulge twice a day.

Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.

The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

Answers

Answer:

A. refutation by parallel reasoning

Explanation:

A refutation by parallel reasoning is an analogical inference between two arguments. This type of refutation occurs when an argument is invalidated by showing that the argument's conclusion is not supported by its premises, thereby the structure of the argument is incorrect. The parallel argument should demonstrate that the premises of the target argument are founded in a fallacy or don't provide a strong enough rationale to support/accept its conclusion.

Who are Chyangra Goats?

Chyangra goat is a type of famous breed of mountain goats which is found in the high altitude areas of the Himalayan region. It produces the world's most expensive and finest quality of luxurious cashmere wool. It is also used for meat. They are more famous for the development of the world famous pashmina wool industry in Nepal and India.

Pashmina wool is a natural adaptation of the Chyangra goat that protects the animal from extreme weather conditions around the Himalayas. The specialty of pashmina is that it can retain enough heat to protect the animal from the severe cold and strong wind of the high mountains all year round.

Thus, Pashmina wool is a natural adaptation of the Chyangra goat that protects the animal from extreme weather conditions around the Himalayas. That is why they are farmed only in cold regions.

Each of DNA's four kinds of bases can pair with

pairing rules, which of the following is the correct
order of bases that would pair with the following
string of bases on a DNA molecule:
Adenine, guanine, guanine, cytosine, thymine,
adenine
O A. Cytosine, thymine, thymine, adenine,
guanine, cytosine
O B. Thymine, cytosine, cytosine, guanine,
adenine, thymine
O C. Thymine, adenine, adenine, guanine,
cytosine, thymine
O D. Guanine, adenine, adenine, thymine,
cytosine, guanine

Answers

Answer:

The correct answer is - B. Thymine, cytosine, cytosine, guanine, adenine, thymine.

Explanation:

According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T)  and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.

Here, the bases are -

Adenine, guanine, guanine, cytosine, thymine,  adenine

the string of their base pair would be:

Thymine, cytosine, cytosine, guanine, adenine, thymine.

Cory states the following argument about the evolution of aardvarks and anteaters.

"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."

Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.
D. A long, sticky tongue evolved in response to the tunneling behavior of ants, an example of coevolution.

The Sun causes tides just like the Moon does, although they are somewhat smaller. When the earth, Moon, and Sun line up—which happens at times of full Moon or new Moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.
