Answer:
The correct answer would be a. Fragments of DNA that have desired genes are isolated to form recombination DNA for use in a host. Genetic engineering refers to the direct manipulation or modification of the desired gene in a cell in order to produce novel or improved organism.
Explanation:
<u>Temperature, humidity and elevation </u>are the two major factors determining the distribution of terrestrial biomes.
- A region of land with a similar climate and comparable plant and animal communities is referred to as a terrestrial biome. Different terrestrial biomes are typically described in terms of the trees, shrubs, and grasses that inhabit them.
- The Terrestrial biome type is influenced by variables including latitude, humidity, and elevation:
- A Terrestrial biome's latitude indicates how far it is from the equator. You will find the Arctic, boreal, temperate, subtropical, and tropical biomes as you move from the poles to the equator
- The amount of water in the air is known as humidity. Humid air is defined as having a high concentration of water vapor.
- The biomes will be referred to as semi-humid, semi-arid, or arid as we move away from the most humid environment (the driest).
- Elevation refers to the elevation of land above sea level. It becomes chilly.

Answer:
In case of sunstroke the body is unable to sweat because the body is dehydrated.
The temperature of the body won't increase further because there can be no more evaporation in body as it cannot sweat more from the skin surface.
The skin dissipates the heat and cools the body preventing the overheating of the body.
The skin appears to be red in color because the blood is dilated and dissipiated into the whole body for cooling.
