Answer : The correct option is, (d) O_2

Explanation :

Cellular respiration : It is a type of process in which the glucose molecule react with the oxygen to form a great amount of energy in the form of ATP and carbon dioxide and water as a byproducts.

The balanced equation for cellular respiration will be,

C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O+ATP

Food as a glucose and oxygen are the input for the cellular respiration.

Hence, the correct option is, (d) O_2

What do all atoms of the same element have
nordsb [41]

Answer:

All atoms of the same element have always have the same amount of protons.

Explanation:

Atoms of the same element have always have the same amount of protons but not always the same electrons and neutrons. If an atom gains or loses one of its valance electrons, the electrons on the outermost shell, then it becomes ionized. Also not all atoms of the same element have the same amount of neutron. This is called an isotope. A good example would be Carbon 13. Normally, Carbon atoms have an atomic mass of 12 AMU or 12 atomic mass units. However, Carbon atoms have an atomic mass of 13 AMU, consisting of 7 neutrons instead of 6 neutrons. So the only thing that all atoms of the same element have in common is the amount of protons.

A 1.68 g sample of water is injected into a closed evacuated 5.3 liter flask at 65°C. What percent (by mass) of the water will b
Angelina_Jolie [31]

Answer:

50.4 % of the water will be vapor

Explanation:

<u>Step 1:</u> Data given

Mass of water = 1.68 grams

volume of the flask = 5.3 L

Temperature = 65°C

Vapor pressure of water at 65°C = 187.5 mmHg = 0.2467 atm

<u>Step 2:</u> Calculate moles of H2O

p*V=n*R*T

⇒ p = the pressure of water = 0.2467 atm

⇒ V = the volume of the flask = 5.3 L

⇒ n = moles of water

⇒ R = gas constant = 0.08206 L*atm/ K*mol

⇒ T = the temperature = 65°C = 338 Kelvin

n = (p*V)/(R*T)

n = (0.2467 * 5.3) /(0.08206* 338)

n = 0.047 moles

<u>Step 3:</u> Calculate mass of water

Mass of water = moles of water * molar mass of water

Mass of water = 0.047 moles *18.02 g/mol

Mass of water = 0.84694 grams

<u>Step 4:</u> Calculate the percent of water vaporized

% = (0.84694 grams/1.68 grams) *100%

% = 50.4%

50.4 % of the water will be vapor

Three examples why cell division is important
kifflom [539]

Answer:

Cell division is important for growth,maintenance of proper chromosome number,wound healing

Explanation:

1 Cell division results in the formation of new cells which further undergo division to form new cells and so forth.Thus many cells are formed which are organized in tissues.Tissues then builds up organs and a number of organs builds up total body.

2 Cell division helps to maintain its chromosome number within the newly formed daughter cells.

3 Division of cells result in the formation of new cells in the site of wound and this accumalation of new cells in the wound region replace damaged and dead cells thus ultimately results in wound healing.
