Neuroeffector junctions are varicosities where motor neurons release neurotransmitters to non-neuronal target cells. These junctions can be observed along the axon.
- The motor nerve varicosities RELEASE neurotransmitters onto smooth muscle cells.
- There are many varicosities along the axons of the neurons that feed smooth muscle cells.
- When autonomic neurons are stimulated, varicosities release neurotransmitters along their axons.
- These neurotransmitters then diffuse through the interstitial fluid to interact with receptors in the smooth muscle cells.

I believe they should not be allowed to use in United States. Since the result reports are not supporting or providing clear information on how it is safe to use, we should not permit its use. Secondly, there are many health threats linked to the use of DDT in world war 2.
Moreover, we are also unfamiliar with the long term effects of these chemicals. Who knows if they are contributing to health threats.
However the associated health threats of DDT and its breakdown products are mentioned below:
- Breast & other cancers
- Male infertility
- Miscarriages & low birth weight
- Developmental delay
- Nervous system & liver damage
Answer:
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
