A-plant Vacuoles are the largest in plant cells.
Answer:
C. is unstable, with a short half life
Explanation:
Paracrine hormones are the hormones that act on neighboring cells only. These hormones or chemicals are largely unstable and have a brief life as do not visit the distantly placed target cells. For instance, somatostatin is secreted by D cells of the pancreas. It acts in a paracrine manner and inhibits the discharge of hormones from the neighboring beta and alpha cell.
Likewise, one of the functions of unstable NO gas is to serve as a vasodilator. It is released by epithelium cells and serves to dilate arterioles and relax precapillary sphincters. Then it is degraded.
Pollution is the biggest impact as well as deforestation
1) The six kingdoms in the six-kingdom system of classification are Archaebacteria, Eubacteria, Protista, Fungi , Plantae and Animalia
2)The two things that make archaebacteria difficult to study are that archaebacteria lived only in these extreme environments and that we don't know how to feed them for studying them
3) Protista is the most heterogeneous kingdom in terms of morphology
4) The difference between kingdom and domain is that the kingdom is one of the five major groups of living organisms while the domain is one of the three taxonomic categories of living organisms above the kingdom level.
Sorry if i’m late to answer it
I hope it’s correct
I honestly don't remember much about this and I'm sure someone else will answer more thoroughly for you but I believe it is the "<span>messenger". It carries instructions from DNA to conrol the synthesis of proteins</span>
