ability to move in response to environmental stimuli

3. which cell structures are correctly paired with their functions?

1points
a
the mitochondria produce enzymes and ribosomes transport them.

b
the ribosomes make proteins and the nucleus stores genetic information.

c
the cell membrane makes enzymes and cytoplasm transports them.

d

4. what term describes the light-absorbing molecule that plants use to absorb energy?

1points
a
grana

b
pigments

c
stroma

d
thylakoids

For Question Two: The answer is "to store hereditary information." If you require further explanation, please ask.

Explanation:

All prokaryotes and eukaryotes contain nucleic acids, which store hereditary information.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
