Answer:
Blood Brain Barrier(BBB)
Explanation:
This is a biological interface of special endothelial cells of astrocytes, pericytes , capillaries, neurons and other structures, acting as a physical barrier or gate separating the Central Nervous system from the peripheral blood circulations. Thus it formed a tight junction serving as a physical barrier to selectively regulate the entrance of substances from the cerebral blood flow into the brain, therefore maintaining homeostasis of the brain.
From above any substances absorbed into the blood stream irrespective of the mode of entry are transported through the BBB, and are selectively regulated to enter the brain cells by the BBB's interactions with the blood vessels, hormones etc.
Basically it allows the passage of nutrients, a few drug, hormones and resists certain toxins and pathogens for the brain homeostasis.

Answer:
Glomeromycota
Explanation:
The phylum Glomeromycota represents a group of fungi where all representatives of this division reproduce asexually forming Glomerospores as reproductive structures. These fungi are characterized by being a species that introduces genetic diversity in the population during reproduction, creating a diploid zygote that results from the union of the nuclei of two mutually compatible cells.
Answer:
During photosynthesis the tree while convert the energy from sunlight into sugar (glucose). The xylem will transport the water to the leaves. The phloem will transport the glucose. The energy from sunlight will also be used to convert water and carbon dioxide into oxygen and glucose. Hence, the energy stored within the glucose/sugar molecules will be used to help the tree grow.
Explanation:
I wrote it in my own words but it will probably say i took it from go ogle since used similar terms apparently.
hope this helps and is right. p.s i really need brainliest :)
