Answer:
Explanation:
The above mentioned key points are mechanisms by which cells used to correct replication error and repair damaged DNA.
Proof Reading: while printing a page, the typesetter set the types and impression is taken, proof reading is done to correct mistakes if any, and the final printing is done. A similar follow up mechanism is done after DNA synthesis. If DNA polymerase detects an incorrect nucleotide pair, it will remove and replace with the correct nucleotide immediately.
Mismatch Repair:even after DNA synthesis, mismatch area(insertion or deletion) can be identified on the newly synthesized DNA.
In the mismatch repair, specific proteins scan the newly synthesized DNA strand. The mismatch area is identified and loop.
The second protein complex remove the mismatch segment. Finally correct segment is synthesized by the help of DNA polymerase, SSBs and ligase.
DNA damage repair mechanism: when DNA get damaged, there's a repair process that fix the damage. This includes Direct reversal, excision repair and Double stranded break repair

Since each parent contributes 1 allele to their offspring, we can expect a even distribution of 4 allele combinations in the offspring of these fish. They are
s1s2 = s1 from 1st parent, s2 from 2nd parent
s1s4 = s1 from 1st parent, s4 from 2nd parent
s3s2 = s3 from 1st parent, s2 from 2nd parent
s3s4 = s3 from 1st parent, s4 from 2nd parent
Since both the s1s4 and s3s2 offspring have 5 units of color, that would indicate that 50% of their offspring will have 5 units of color.</span>
Some environmental factors are how many deer there are in that park. If there is not a lot of deer, then the deer bag limit shouldn't go up, otherwise, there would be no more.
Answer:
The moving of water causes erosion, deposition and much more!
Explanation:
Water moving across the earth in streams and rivers pushes along soil and breaks down pieces of rock in a process called erosion. The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river.
Problems related to STDs affects male reproductive system. STD can also affect male fertility. Chlamydia, when left untreated, may spread to the testicles from the urethra, causing permanent sterility and disability. Pelvi inflammatory disease is common STD that affects fertility. A low sperm count and low sperm motility are indicators of this condition. Also, elevated FSH levels and other hormonal problems are indicative of testicular damage. Some STDs like gonorrhea and chlamydia can cause infertility by blocking the epididimis or tubes.
