Answer:
The correct answer is -
1. right-handed
2. right-handed
3. positive
4. left-handed
5. negative
6. negative
Explanation:
In a circular bacterial chromosome, the structure of DNA is a right-handed double helix In a circular bacterial chromosome.
If DNA is twisted in the right-handed direction, it becomes overwound. Overwinding results in positive supercoiling takes place. If DNA is twisted in the left handd direction, it becomes underwound. Underwinding results in negative supercoiling.
f. One effect negative supercoiling in bacterial chromosomes is to promote separation of the two strands of DNA in the double helix
D all of the above but still not sure
The answer is dilation or expansion. It is because ureterectasis
is a process of which the ureter of an individual is being stretch out that is
why it is being referred to as dilation or an expansion of the area.
Answer:
B. There is less biodiversity in the high tide zone because the tidal changes make survival difficult.
Explanation:
The high tide and low tide zones are located on the seashore as the ocean water merges with land.
High tide zones are usually covered with water during high ocean tide while low tide zones are always submerged in water.
There is low biodiversity in the high tide zone because the tide here changes rapidly and organisms find it difficult to adapt. Organisms that inhabit here must be welll adapted to withstand peroids of high tides.
You can infer that the parts of the body with the most touch receptors are the most important in receiving touch stimuli from the environment.
