D. oxygen is used to break down glucose into energy

Explanation:

During respiration, oxygen is used to break down glucose into energy:

          C₆H₁₂O₆  + O₂   →  CO₂   +  H₂O  + energy

In the process of respiration, oxygen gas combines with glucose to liberate energy.

  • Respiratory system in the body is responsible for the metabolic break down of food to provide energy for the working of the human body.
  • Chemical energy in glucose is broken down to produce other forms of energy most especially heat.
  • The by product is usually carbon dioxide and water vapor.

5. Molds and bacteria contain hydrolytic enzymes used to breakdown proteins,
Tpy6a [65]

Answer:Temperature affects storage time and food deteriorates faster at higher temperatures. Microorganisms grow rapidly at room temperature . Thus to slow microbial growth, enzymatic and oxidative processes, food must be stored at room temperature.

Due to decomposition reactions with oxygen or carbon dioxide in the air, meat begins to feel slimy and smell spoiled. ... Because of its smaller surface area, the unsliced meat would have less collisions and therefore, a slower reaction rate.

Consider the synthesis of water as shown in Model 3. A container is filled with 10.0 g of H2 and 5.0 g of O2.
vagabundo [1.1K]

2H2 + O2 → 2H2O

First, we will find the moles :

n H2 = m H2 / Mr H2

n H2 = 10 / 2

n H2 = 5 mole

n O2 = m O2 / Mr O2

n O2 = 5 / 16

n O2 = 0.3125 mole

n H2 / coef. H2 > n O2 / coef. O2

So, O2 is the limiting reactant

The mass of water produced :

n H2O = (coef. H2O / coef. O2) • n O2

n H2O = (2/1) • 0.3125

n H2O = 0.625 mole

m H2O = n H2O • Mr H2O

m H2O = 0.625 • 18

m H2O = 11.25 gr

Excesses reactant :

n H2 = 5 - 0.625 = 4.375 mole

m H2 = n H2 • Mr H2

m H2 = 4.375 • 2

m H2 = 8.75 gr

6. The first system to classify blood types is known as which of the following?
alisha [4.7K]

The first system to classify blood types is known as<u> A-B-O system</u>.

<u>Option: D</u>

<u>Explanation:</u>

The blood group system "ABO" is the categorizing of human blood centered on the hereditary characteristics of red blood cells means erythrocytes as measured by the presence or absence of A and B antigens on the surface of the red cells. Thus individuals may well have blood type A, type B, type O or type AB.

It was absent until 1900, when Karl Landsteiner established the concept at the Vienna University why some blood transfusions were effective while others were lethal. Landsteiner established the blood group mechanism ABO by combining each of his staff's red cells and serum.
