White arctic hares blending in with the white snow in their environment is an example of what type of camouflage?
A. hiding
B. protective resemblance
C. mimicry
D. protective coloration

Answers

Answer:

The answer to your question is A.

D. Protective coloration.  Protective coloration, also known as "crypsis," is a defense mechanism used by animals to avoid detection by predators or prey.

An illustration of protective coloration, which is a sort of camouflage, is how white arctic hares blend in with the white snow around them. Animals use protective coloration, commonly referred to as "crypsis," as a defensive strategy to evade being seen by predators or prey.

In this instance, the white arctic hares' fur is the same shade as that of their snowy environment. Their chances of survival are increased by this merging, which enables them to remain unnoticed and effectively hidden from predators like polar foxes or birds of prey. They have a better chance of escaping or avoiding detection when they are well-camouflaged, making it difficult for predators to see them against the white background.

If the atomic number of an element is 8 and the mass number is 16, the number of neutrons in an atom of that element is what? (show work)

Answers

Answer:

8.

Explanation:

Atomic number tells us the number of protons in an element. Mass number is the total amount of mass in an atom, and it comes from the sum of the mass of protons and neutrons, which are both considered to have a mass of 1 amu.

If the total mass is 16amu and 8amu comes from the 8 protons, the remaining mass comes from neutrons.

16 - 8 = 8

Answer:

1st one is correct

The atom of the reactants unbound , rearrange, and then rebond to form the product

hope it helps

In a chemical reaction, the atoms of the reactants unbond, rearrange, and then rebond to form the products. Therefore, option A is correct.

What is chemical reaction ?

Chemical reaction, the transformation of one or more chemicals the reactants into one or more distinct compounds, the products. Chemical elements or chemical compounds make up substances.

Combustion reaction, decomposition reaction, neutralization reaction, redox reaction, precipitation or double-displacement reaction, and synthesis reaction are some of the numerous types of reactions.

In a chemical reaction, bonds between molecules of the reactant are broken and new bonds between molecules of the product are established to create a new substance.

A chemical equation is nothing more than a mathematical statement that represents how reactants form products.

Thus, option A is correct.
