Membrane potential is the difference in electric potential between the interior and the exterior of a biological cell. Membrane potential is a potential gradient that forces ions to passively move in one direction: positive ions are attracted by the 'negative' side of the membrane and negative ions by the 'positive' one.
Answer: The correct answer is A) Rat.
r- selected species are those, which are capable of producing large number of small offsprings in an unstable environments. These species follow exponential growth rate, does not survive to childhood ( as possess very short life span), and have no parental care.
On the contrary, k selected species are present in a stable environment, have low reproductive rate, long life span, and possess parental care. Whale, Eagle, and Elephant are the example of K- selected species.
Thus, rat is an example of r- selected species.
Cell wall- around the cell
Cell membrane- in the cell wall
Vacuole- large storage area
Nucleus- protects nucleolus
Nucleolus- inside of nucleus
Cell membrane- surrounds nucleus as protection
Chloroplast-makes plant green
Mitochondrion-produces energy
Ribosomes-converts amino acid
Answer:
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. ... Slate is frequently grey in color, especially when seen, en masse, covering roofs.
I believe it is c RNA, because DNA is a storhouse for bio info.....not sure what ATP is hope this helps!
