Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules. ... They can even join "head-to-tail" to make rings of carbon atoms.
On my work the answer was D ..
<span>ER Golgi apparatus, because it packages proteins received from the ER cytoplasm </span>
<span>The Golgi body are the ones that slightly alter, organize and prepare so-called parcels to be delivered for all the organelles in the cell. They receive these packages mainly in the rough endoplasmic reticulum. These packages that set out by Golgi body are macromolecules that used and synthesized by cells in many operations. If ER is absent then it would only mean that Golgi body would have no use other than simply lysosomes but these macromolecules plays a dynamic role in many organelles –nutrients, ATP and cell metabolism. It'll have a ripple effect if ER is absent in the cell.<span> </span></span>
Answer:
A
Explanation:
If it's a permeable membrane then it will allow certain molecules in. If it's impermeable then it won't allow molecules in. Therefore it is the deciding feature of whether something can go into the membrane.
Answer:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. ... So basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen
