Answer:
The form of cell to cell signalling that is been used is ENDOCRINE.
Explanation:
There are four ways by which cell signalling occur in the body, these are: endocrine, paracrine, autocrine and direct signalling.
Endocrine signalling is the biochemical process by which hormone secreting glands release hormones into the blood streams and that hormone has effects on target organs that are located far away from it. Endocrine hormones are usually stable and their effects usually last for long time.
Marfan syndrome is a rare disease of the connective tissue, which affects different structures, including skeleton, lungs, eyes, heart and blood vessels.
It is characterized by an unusual increase in limb length. It is believed to affect one in 5,000 people. Unlike other genetic problems, it does not negatively affect intelligence.
Using my knowledge abiotic factors include things such as wind, rainfall, sunshine, etc. If there are multiple choices to choose from then I could be more specific.
Yes if u cut the tree down and look at the ring on the inside of it it gives u an estimate about how long its been around hope that helps
Magmatic differentiation entails approaches by the way in which chemically one-of-a-kind igneous rocks, along with basalt and granite, can shape from the same initial magma excessive-temperature minerals can crystallize and settle out, causing the ultimate molten fabric to be focused with components that may later form rock enriched in low-temperature minerals (along with granite).
The technique by means of which chemically specific igneous rocks, such as basalt and granite, can shape from the equal initial magma.
Magmatic differentiation can arise by way of the chemical response between the magma and the first crystals to solidify out of it, or by the physical separation of the first crystals that shape from the ultimate magma, both thru settling to the bottom of a magma chamber or thru crustal deformations that purpose the remaining magma to be squeezed out to cool in veins.
