We will attempt to introduce a gene responsible for the resistance to the antibiotic ampicillin.
Bacterial transformation is a molecular technique widely used in genetic engineering. Its basis involves the introduction of a foreign DNA into a host organism. This will result in the expression of a foreign gene by the host bacterium. In this example, our host organism is a bacterium who is sensitive to the antibiotic ampicillin. By introducing a gene for resistance to this antibiotic, the bacterium will become ampicillin resistant.
One of the main source of sediment in flowing water is soil erosion.
Explanation:
Soil erosion is the washing away of top most layer of soil due to various reasons.
Agents of soil erosion are: wind, water, animals, ice or gravity.
Water is one of the biggest agent or cause of soil erosion. Water carry lots of energy in its motion. When water moves from any area it carries away topmost layer of soil with it. The soil that is being carried away by water is sediment.
When this water reach river, lake or any other water source, sediments carried by them enters that source of water. Sediment results in water pollution.
Answer:
C) decreased functional reserve
Explanation:
Ageing is a biological process which leads to the loss of function of the tissue and cells of the organism.
The biological ageing is determined genetically and can be correlated with the chronological ageing. The ageing is also influenced by the environmental factors which could interfere with the physiology, anatomy and morphology of the organisms.
The cell division cycle gets arrested to prevent the proliferation of these damaged cells and to remove the harmful factors from the body. This leads to the loss of function of the cells and tissues.
Thus, Option-C is the correct answer.
The substance that yields a Cation plus the Hydroxyl ion in water is a Base.
A Cation is a positively charged ion. A Hydroxyl ion is an ion with a negative charge and is made up on one oxygen atom and one hydrogen atom. Bases are substances that promote chemical reactions. Dissociation is a process in which ionic compounds split into smaller particles.
<span>In this case, the base acts by dissociation to yield a Cation plus a Hydroxyl ion in water. </span>
