The correct answer is C. The birthrate is higher than the death rate.

Explanation

The graph is about the growth of the world population, this shows the population growth of the world, Asia, Africa, Europe, United States, Canada and Greenland, Mexico, Central America, Caribbean Islands, and South America, and Oceania (Australia and nearby islands in the Pacific). This graph covers the time from 1950 to 2050 divided into decades. In the specific case of Africa in 1950 it had a population of close to 300 million people. Subsequently, in 2010 the population of Africa was close to 1 billion people and the projection for the year 2050 is 2 billion people. According to this, it can be concluded that the birth rate is higher than the death rate because the population has a growth trend, which indicates that more people are born than die.

<h3>☣ Question -:</h3>

Which of these equation is the correct one for fermentation?

❍ Glucose + oxygen → carbon dioxide + water

❍ Glucose → lactic acid

❍ Glucose → ethanol + carbon dioxide

<h3>☣ Explanation -:</h3>

To understand this first we should know what is fermentation.

<u>What </u><u>is </u><u>fermentation</u><u>?</u>

A process of chemical change in food or drink because of the action of yeast which may cause it to produce bubbles or heat, or turn sugars in it into alcohol.

<u>Equation -:</u>

$\small\sf{C_{6}H_{12}O_{6} \rightarrow2C_{2}H_{5}OH + 2CO_{2}}$

Which means

Glucose → ethanol + carbon dioxide

Hence opition c is the correct answer.

1.) Which of the following is an electron carrier used to transfer energy in cellular respiration?

Anestetic [448]

Answer:

1. B. NADH

2. B. hydrolysis of ATP.

3. C. ATP is produced from protein.

4. Option C.

5. Option C. Oxygen

6. Option D. Glucose.

7. Carbondioxide.

8. Metabolism.

9. Electron carriers.

10. Electrons.

Explanation:

Cellular respiration is a series of metabolic processes that break down sugars or food to produce energy. ATP is the cellular energy produced during cellular respiration. Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation. During cellular respiration, glucose is broken down into carbondioxide and water. Along the way, ATP is produced from the processes that transform glucose.
