How does food provide a source of energy for living things ?

Biology

MAVERICK [17]3 years ago

Food has energy in it. When we digest food our body mixes it with acids and enzymes in our stomach. Then our stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The glucose gives us energy.

The surface area/volume ratio is an important factor for one celled organisms. As a cell's volume grows, its surface area/volume
Stells [14]

Answer

Use Mitosis to divide and create daughter cells.

Explanations  

Single-celled organisms use mitosis to reproduce. Both growth and reproduction in unicellular organisms are mutually inclusive. When the cell’s volume grows, the ratio of surface area to volume decreases creating challenges in acquisition of nutrients because there will be too much cytoplasm for a given amount of nuclear material , thus the cell divides by mitosis to reproduce daughter cells and the process begins again.

If the rice already had the genes that could make vitamin A, why did scientists use genes from other organisms?
meriva

Answer:

A. The rice genes didn't make the right type of vitamin A.

Explanation:

Regular white rice does not have the gene to produce beta carotene. The human body converts the beta carotene into vitamin A.

To increase the nutritional value of rice, the gene for beta carotene from daffodil flowers was inserted into the cells of endosperm of rice.

This allowed these cells of the genetically engineered rice varieties to produce beta carotene. Production of beta carotene imparted golden color to the rice grain and hence, the name.

Full meanings of NADH+ and FADH​
Valentin [98]

Answer: NADH stands for "nicotinamide adenine dinucleotide (NAD) + hydrogen (H)." This chemical occurs naturally in the body and plays a role in the chemical process that generates energy.

Explanation: FADH is the reduced form of flavin adenine dinucleotide (FAD). ... FADH is generated in each round of fatty acid oxidation, and the fatty acyl chain is shortened by two carbon atoms as a result of these reactions; because oxidation is on the beta carbon, this series of reactions is called the beta-oxidation pathway.
