Answer: D. The genes for antibiotic resistance help the transformed bacteria survive in their environment.

Explanation:

First and foremost, we should note that plasmids used in the delivery of DNA typically consists of genes which helps in antibiotic resistance.

Based on the question given, we should note that the genes for antibiotic resistance help the transformed bacteria survive in their environment. This is because cells that have been treated with plasmid are able to survive and grow compared to those that have not been treated with plasmid which are eventually killed by the antibiotic.

The pH of a solution containing 0.1 mM H+ is _______ ( 1mM = 10-3M)

Taya2010 [7]

Answer:

The pH of a solution containing 0.1 mM H+ is 4

Explanation:

The pH of any solution is given by the following mathematical equation -

$pH = -log[H_{+}]\\$ ----------- Equation (A)

Where,

$H_{+}$ = the concentration of hydrogen ion in the solution.

Given

$H_{+}$

= $0.1mM\\=0.1 * 10^{-3}\\= 10^{-4}\\$

Substituting the given value in equation (A) , we get -

$pH = -log[10^{-4}]$

$= -(-4)\\= 4$

Hence, The pH of a solution containing 0.1 mM H+ is 4

The stomach,small intestine, esophagus or liver secretes special enzymes that help the stomach digest fats.

scZoUnD [109]

Explanation:

<u>The stomach </u>

Digestion describes the intake, chemical and physical breakdown, absorption of nutrients and excretion of food with the use of enzymes. The stomach secretes the enzyme, gastric lipase to digest fats.

Further Explanation:

Food is chemically and mechanically broken down into smaller particles. In the stomach the enzyme gastric lipase acts on lipids, breaking them up into their components. Phospholipids, bile acids, bilirubin, and cholesterol are combined into bile in the liver, which when secreted into the duodenum of the small intestine; this comes from its storage site, the gall bladder, and functions as an emulsifier or as a detergent.

These hold the fats and water together and increase the surface area of lipids, which can be further digested by enzymes so the nutrients are further broken down for absorption into the bloodstream.
