Answer:
1. Today instead of rotating upright, The earth's axis is tilted 23.5 degrees. The angle varies a little over time, but the gravitational pull of the moon prevents it from shifting by more than a degree so. This tilt is what gives us seasons.
2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the earth's approximately 23.5° tilt, the season in the northern and southern hemispheres reversed, about six months apart from each other.
Site-specific recombination systems all of the choices are correct i.e.
A. do not depend on extensive nucleotide sequence homology.
B. depend on enzymes that are often specific for sequences within the host.
C. are features of some viruses.
- An exchange between two specified sequences (target sites), either on the same DNA molecule or on two separate DNA molecules, is known as site-specific recombination.
- DNA sequences may be integrated, excised, or inverted as a result of the exchange.
- A site-specific recombinase that can work by itself or with the aid of additional components or enzymes shapes the DNA target during recombination.
- The recombinase is chemically bonded to the ends of the intermediate DNA after DNA breakage at the recombination site; when this process is reversed, the intermediate DNA is resealed to form the recombinant and the recombinase is released.
- During this recombination process, neither replication nor repair are necessary.

Answer:
I think its C
Explanation:
when the roller coaster is at a high point, it has potential energy but no Kinetic energy but I could be wrong so
Answer:
25%
Explanation:
So there are 4 recessive alleles present for black fur on the square and there are also 4 dominant alleles. As there are the same amount of dominants as recessives the dominants will take over and be in control so the recessive alleles won't have as much of a chance
