The hypothesis that yellow snails are better camouflaged in grasslands than brown snails is true because yellow shelled one is difficult to catch from the grassland by birds. Thus their percentage will be higher.
The natural selection is for the one who better survives by any strategy. Here the yellow shelled snails are naturally selected to live more by its appearance.
By studying the birds population, scientists can easily understand how much the snails can over come and the percentage of population remaining there.
What is camouflage?Camouflage is the property exhibited by some animals which to change their color that matches the surroundings so that it will be difficult to see them.
The hypothesis is true based on the camouflage of snails because in grass lands there are both yellow and green grasses and in between these colors yellow shelled snails are difficult to find.
Thus, their percentage will be higher in grasslands than that of brown shelled snail.
Nature selection of living is in such a way that the fittest is survived. Here, the yellow-shelled snails are hard to caught by birds because of their appearance and their population will be higher.
It is said that birds are the main predators of snails. Therefore, by studying the birds population over the area they can study the decrease in population of snails and the chances for their survivals.

Over years of selective breeding, French bulldogs have developed extremely short snouts and flat faces. These traits, although attractive to the dog owners, can make it difficult for the dogs to breathe.Which of the following processes led to the presence of these traits?
(Choice A)
A
Artificial selection
(Choice B)
B
Natural selection
(Choice C)
C
Environmental selection
(Choice D)
D
Sexual selection
Answer:
Artificial selection
Explanation:
Choice A, artificial selection, led to the presence of these traits in French bulldogs.
What is Artificial selection?Artificial selection, also known as selective breeding, is the process of breeding organisms with desirable traits in order to produce offspring with those traits. In the case of French bulldogs, humans selectively bred dogs with shorter snouts and flatter faces in order to create a breed that was aesthetically pleasing. However, these traits also led to health problems such as difficulty breathing.
Natural selection, on the other hand, is the process by which organisms with advantageous traits are more likely to survive and reproduce, leading to the evolution of those traits in a population.
Environmental selection refers to the process by which the environment favors certain traits over others. Sexual selection is a type of natural selection that occurs when individuals with certain traits are more likely to attract mates and reproduce.
In the case of French bulldogs, these traits were not naturally selected for based on survival advantages, nor were they the result of environmental or sexual selection. Rather, they were artificially selected for by humans, leading to unintended consequences for the dogs' health.

Explain the process of DNA Replication in details
When will DNA replication occur?
(They don’t have to be too long just long kinda lol)
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase).

Answer:
The expansion of water upon freezing is vital to life on Earth. It is what causes ice to be less dense as a solid than as a liquid. This means that ice floats in liquid water. ... Water freezes when its molecules are no longer moving around enough to break their hydrogen bonds.
Explanation:

The mass of the earth is 81 times the mass of the moon. Using Newton's Law of Gravity what would the affect of gravitation be if the mass of the moon were doubled and the distance was also doubled?
Group of answer choices
4 times the gravitational attraction
twice the gravitational attraction
1/4 the gravitational attraction
Half the gravitational attraction
Answer:
it would be half the the gravitational attraction(D) because the distance Has doubled.
If the mass of the moon were doubled and the distance between them is also doubled, then it will have half the gravitational attraction. The correct option is D.
What is gravitational force?The gravitational force is basically a force that attracts any two mass-bearing objects. The gravitational force is called attractive because it always tries to pull masses together rather than pushing them apart.
According to Newton's law of gravitation, the force of gravitation is inversely proportional to the square of the distance between the bodies. Thus, doubling the distance reduces the force of gravitation by 1/4.
If one of the objects' mass is doubled, the force of gravity between them is also doubled. If one of the objects' mass is tripled, so is the force of gravity between them. If the mass of both objects is doubled, the gravitational force between them is quadrupled, and so on.
Now, here, the mass is being doubled which is making the gravitational attraction doubled. But distance is also increasing by two.
So in this case, the gravitational attraction will get 1/4, so the net attraction will be half.

is formed when one or more than one atom bonds to another atom.
Explanation:A special case of polar forces occurs in what is called the hydrogen bond. In many situations, when hydrogen forms a covalent bond with another atom , electrons move toward that atom, and the hydrogen acquires a slight positive charge. The hydrogen, in turn, attracts another atom, thereby forming a kind of bridge between the two.

______ breaks down fibrin and restores the fluidity of plasma.
A. Fibrogen
B. Plasminogen
C. Plasmin
D. All of the above
Answer: A. Fibrogen
Explanation: A fluid called serum (plasma minus fibrinogen and prothrombin) is squeezed from the clot. A fibrin clot is present only temporarily. As soon as blood vessel repair is initiated, an enzyme called plasmin destroys the fibrin network and restores the fluidity of the plasma.
Fibrinogen breaks down fibrin and restores the fluidity of plasma, during blood clotting. Hence, option A is correct.
What is the process of blood clotting?Coagulation is the term for the multi-step process that causes blood to clot. Blood binds securely together at the site of an injury when the entire coagulation process is functioning effectively, and bleeding ceases. When you have a bleeding issue, you can't quickly or at all form powerful clots.
Plasma-derived proteins known as blood clotting factors or coagulation factors are used in the coagulation cascade, a sophisticated chemical process. Simply put, the clotting process converts blood at the site of an injury from a liquid to a solid.
The enzyme converts the plasma protein fibrinogen, which is soluble, into fibrin, which is insoluble. Some red blood cells get caught in a net made of fibrin, which is sticky and creates lengthy threads. This creates blood clots. Therefore, option A is correct.
