Answer:
because there is not a lot of anything in that layer so anything that comes into it creates a reaction, heat
Explanation:
Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere"
Or they could have evolved to adapt to their environment. Because of these mutations, they’re more beneficial to their species and can survive.

The identification of an individual by the means of genetic engineering is possible because the Y chromosomes in the males does not experience any crossing-over as there is only a single Y chromosome present in a human male.
The mitochondrial DNA is passed from the mother to child in the cytoplasm of the cell, and it is passed on without any changes. The X chromosome is can be passed from a mother to her son as he will receive Y chromosome from his father.
Hence, the correct answer is 'Option B - The Y chromosome does not experience crossing over'.
Answer:
b. Immnofluorescence
Explanation:
Immunofluorescence involves the reaction of a fluorescently labelled antibody to an expressed gene or protein making it specific. A microscope is used to locate the expressed gene via the fluorescent dye activated by light of a certain wavelength. It is usually done to analyze intact cells or tissue therefore it is easier to localize the gene expression.
