I believe that the loop of Henle is the hairpin structure that connects the proximal and distal convoluted tubules. The loop of Henle is composed of the ascending and the descending limb. The descending loop of Henle connects the proximal convoluted tube with the ascending limb of the loop of Henle, while the ascending loop of Henle connects the descending limb of the loop of Henle with the distal convoluted tubule.
I also think it should be B
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
Answer:
<u>Benefits</u>:
pesticides can keep harmful pests–such as rats, mice, ticks and mosquitoes–away from crops while also protecting the plants from weeds and diseases that have the ability to greatly reduce crop yield.
<u>Environmental impacts</u>:
Pesticides may move with runoff as compounds dissolved in the water or attached to soil particles. Runoff from areas treated with pesticides can pollute streams, ponds, lakes, and wells. Pesticide residues in surface water can harm plants and animals and contaminate groundwater.

The purpose of the naked axon with larger dendritic field which is called unmyelinated axon is to receive as much input as possible.
