Answer:
The barrier functions to regulate the chemical composition of the extracellular fluid surrounding the brain cells.
Explanation:
Blood-brain barrier
It is a very selective semipermeable membrane , hence allow some specific substance to pass via it . This barrier separates the extracellular fluid in the central nervous system and the circulating blood from the brain .
<u>The barrier is composed of the endothelial cells .</u>
Passive diffusion is shown in this system , and allows molecules like the water , glucose , amino acid to pass .
It regulates the chemical composition of the fluid of brain cell .
Interleukin-5 (IL-5). IL-5 is responsible for the recruitment and maturation of eosinophil. Eosinophils on the other hand are majorly involved in the inflammatory response in asthma- characterised by narrowing of the airways. Mepolizumab and reslizumab are, therefore, anti-IL-5
It is Nucleic Acids, they consist of long chains of units like the proteins, but still both are different.
Answer:
homologous structure
Explanation:
those organs which have the same basic structure but have different functions are known as homologous organs/structures.
POLLEN GRAIN, SEED COAT, MEGASPORANGIUM AND EMBRYO. <--- ANSWER
Gymnosperms are seed bearing plants, which do not have the combination of specialized features that characterized the flowering plants.
