Answer:
<h2>
A
</h2>
Explanation:
1. A channel between two adjacent cells in known as an intercellular cleft.
2. And through these channels many molecules can easily pass between cells.
3. Importance of Intercellular clefts:
i) It is very important in transportation of fluids and small solutes.
ii) It contains gap junctions, tight junctions, desmosomes, and adheren proteins and these junctions help in regulate cell communication by signal transduction, surface receptors, or a chemogradient.
C because if there isn’t enough of something, more can be added but if there is max capacity, nothing can be added
In recent molecular genetic studies, genes associated with the neurotransmitter Dopamine have been linked to ADHD.
ADHD stands for Attention Deficit Hyperactivity Disorder. People with ADHD have a hard time focusing on tasks. Scientists have found that the low levels of dopamine in the brain are associated with the symptoms of ADHD. It is because the neurons in the brain have a high amount of protein called the dopamine transporters. These proteins block the dopamine from passing between the neurons. This decreases the effect of dopamine.
The asthenosphere and outer core would solidify.
<span>However, these advancements that other people are talking about will not probably last for very long since much resources were used to exploit and overuse the natural resources we currently have. The question of what about the future populace who are significantly viable to live under this planet, 100 years from now? Isn't that claim sort of egotistical?
Exploitations lead to different global ecological changes like the occupation of the invasive species which can threaten an ecosystem and the biodiversity of the organism that exist in the present environment when the invasive species increase rapidly in number.
