Answer:
Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences.
Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends.
DNA ligase is a DNA-joining enzyme. If two pieces of DNA have matching ends, ligase can link them to form a single, unbroken molecule of DNA.
In DNA cloning, restriction enzymes and DNA ligase are used to insert genes and other pieces of DNA into plasmids.

Answer
<u>A) Segregation</u>
Explanation:
In Mendel's law of Segregation, each allele is inherited separately from each other within gametes- each gamete can only carry one gene.
Transposons refute this; here, variegation (regions of multiple colors) may occur due to "jumping genes" leading to multiple phenotypic variants like a multicolored seed,instead of a seed retaining one solid color. Mendelian ratios, thus, are not observed.
This is seen in instances such as Indian corn- these seeds may be purple, red, green and yellow. Variegation of seed color can occur to produce multicolored grains of purple and white.
What are you asking? Slope? If so. You would do change in y over change in x. So subtract 2 and -4 to get positive 6, then subtract 6 and -3 to get positive 9. Your slope is either 1/3 if it’s increasing, or negative 1/3 if it’s decreasing.

Explanation:
Ozone is a gas composed of three atoms of oxygen. Ozone occurs both in the Earth's upper atmosphere and at ground the level.Ozone at ground level is such a harmful air pollutant, because of its nasty effects on people and the environment, and it is the main ingredient in a type of air pollutant called “smog."
