why is respiration considered an exothermic process​

Answers

Answer:

Respiration is considered as exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form carbon dioxide and water along with energy.

Explanation:

Good Luck!

Respiration is considered as an exothermic reaction because, in the respiration process, oxidation of glucose takes place which produces a large amount of heat energy stored in the form of ATP. This is shown in the following chemical equation C 6

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.

A rectangular poster is /4 yard wide and / yard tall. What is its area? Solve this problem any way you choose

Answers

Answer:

Area of rectangular poster = [tex]\frac{3}{16}[/tex] yard²

Explanation:

P.S - The exact question is -

Given - A rectangular poster is [tex]\frac{1}{4}[/tex] yard wide and [tex]\frac{3}{4}[/tex] yard tall.

To find - What is its area ?

Proof -

We know that ,

The area of rectangle = Length × Breadth

Here,

Given that,

Length of rectangle = [tex]\frac{3}{4}[/tex] yard

Breadth of rectangle = [tex]\frac{1}{4}[/tex] yard

∴ we get

Area of rectangular poster = [tex]\frac{3}{4}[/tex] × [tex]\frac{1}{4}[/tex]  yard²

                                          = [tex]\frac{3}{16}[/tex] yard²

⇒Area of rectangular poster = [tex]\frac{3}{16}[/tex] yard²

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.

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
