Suppose that you have a laboratory technique that allows you to label (with color, for example) snrnps within a cell. where would you expect to see positive staining in a eukaryotic cell?
a. the nucleus
b. the cytoplasm
c. the mitochondria
d. the lysosomes
e. the plasma membrane

Option A, the nucleus

Explanation:

snRNPs, or small nuclear ribonucleoproteins, are RNA-protein complexes that combine with unmodified pre-mRNA and various other proteins to form a spliceosome, a large RNA-protein molecular complex upon which splicing of pre-mRNA occurs

Splicing occurs in the nucleus hence positive staining will likely be observed here.

carbon atoms, hydrogen, oxygen, and nitrogen.

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
