Biology
1 answer:
Sauron [17]3 years ago
6 0

Answer:

C

Explanation:

The DNA in all the cells of an organism are the same. The reason there are different types of cells in the organism even through their DNA is the same is because genes are deferentially expressed in the cell types. The genes that are expressed in the brain cells are different from those expressed in the liver.  The rest of the genes that are not being expressed are silenced through folding by histones – so they are not exposed to DNA polymerase.

Many foods must be refrigerated to prevent spoiling (microbial growth). Explain why honey (which is ∼82% carbohydrate by weight)
VLD [36.1K]

Answer;

-Honey contains a considerable amount of sugar (about 82% carbohydrate) and therefore when a microbe (e.g., a fungal spore or bacterium) lands on honey the process of osmosis causes water to be drawn out of the microbe thus blocking its ability to live and proliferate.

Explanation;

Antibiotics are used to kill or inhibit bacteria growth. Honey contains hydrogen peroxide, which may account for some of its antibacterial properties. It also has a high sugar content, which can help stop the growth of certain bacteria.

-Additionally, honey has a low pH level. This works to pull moisture away from bacteria, causing the bacteria to get dehydrated and die off.
