What is the process called that living things perform to make useable energy fromsugar?
-photosynthesis
-exercise
-heterotrophs
-cellular Respiration
Answers
Answer:
cellular respiration
Explanation:
Organisms ingest large molecules, like carbohydrates, proteins, and fats, and convert them into smaller molecules like carbon dioxide and water. This process is called cellular respiration, a form of catabolism, and makes energy available for the cell to use.

Answer:
The wall of the arteries belongs to the circulatory system. The fat deposit belongs to the adipose connective tissue.
Explanation:
The arterial system is the high pressure portion of the circulatory system. Blood pressure ranges from the maximum pressure during cardiac contraction, called systolic pressure, to the minimum pressure, or diastolic pressure, between contractions when the heart rests between cycles. This variation in pressure in the arteries produces a pulse that is observable in any artery, and is an indicator of cardiac activity. The wall of the arteries is thick, formed of elastic muscle tissue.
Adipose tissue is a type of connective tissue with special properties. It has many adipocytes, specialized cells, which have the main function of energy reserve, through a fat deposit, for the body, among others. Fat is deposited in fat cells also called adipocytes.
Final answer:
The arterial wall and fatty deposit belong to the cardiovascular system.
Explanation:
The arterial wall and the fatty deposit belong to the cardiovascular system in the human body.

Answer:
The empirical formula of P4O10 is P2O5 . This is arrived at by dividing both subscripts by their highest common factor 2.
Explanation:
Empirical Formula of a compound is the lowest whole number ratio between the compound elements it is sometimes different from the standard formula of the compound).
The molecular formula is the formula derived from molecules and is representative of the total number of individual atoms present in a molecule of a compound.The empirical formula of the compound whose molecular formula is P₄O₁₀ is P₂O₅.
The empirical formula of a compound provides the simplest ratio of the number of various atoms present. It is an empirical formula if it has been simplified. The molecular formula is commonly used and is a multiple of the empirical formula.
Molecular Formula = n × Empirical Formula
On dividing both the subscripts of the formula P₄O₁₀ by 2 we get the empirical formula as P₂O₅.

Answer:
the change in internal energy per mole of sucrose is 5989 KJ/mol
Explanation:
Since the calorimeter is a bomb calorimeter , where the volume remains constant
ΔE= Qrx
And assuming no heat losses to the surroundings
Qv + Qrx = 0
Cc*ΔT - Qrx = 0 ,
Qrx = Cc * ΔT = 7.50 KJ/°C * 22 °C = 165 KJ
the change in internal energy is calculated dividing by the number of sucrose moles involved n. the molecular weight of sucrose is
Mw= 12* 12g/mol + 22* 1g/mol + 11* 16 g/mol = 342 g/mol
n = m / Mw = 10 g / 342 g/mol = 0.029 mol
the change in internal energy per mole of sucrose is
Δe= ΔE/n = 165 KJ/0.029 mol = 5989 KJ/mol
