Answer:
B) Na+
Explanation: Na+ molecule is polar, oxygen and carbon dioxide are nonpolar molecules. The cell membrane is a <em>phospholipid bilayer</em> made up of lipid molecules with polar and nonpolar ends. Since it is a bilayer, two phospholipid layers are arranged, one on the other in such a way that one faces the back of the other. The non polar ends are away from outside and inside of the cell, while the polar ends faces towards all the molecules inside and outside the cell.
Since polar-polar molecules repel each other, Na+ can't pass through the cell membrane easily. So it uses the proteins attached the cell membrane inside and outside to transport such molecules by using energy in terms of ATP.
Answer:
C. Mean
Explanation:
sir / ma your question isn't clear. That aside.
to know how population size of species affect the sustainability we find the mean carrying size(just a guess)
The appropriate response is lysine. Lysine is a basic amino corrosive. Many individuals realize that few amino acids are known as the "building squares of protein" and are required all together for a colossal number of appropriate inner capacities, including development.
There are numerous unbelievable L-lysine benefits, from its utilization as a typical treatment for mouth blisters to a potential against nervousness supplement. As is valid with most supplements accessible in supplement shape, L-lysine can be taken orally yet is assimilated best into the body when devoured through nourishment. It's found in substantial sums in different sorts of meat, beans, cheeses, and eggs.

Answer: What is the defining characteristic of eukaryotic cells? Put these in your own words.
Eukaryotic cells are defined by the presence of a nucleus containing the DNA genome and bound by a nuclear membrane (or nuclear envelope) composed of two lipid bilayers that regulate transport of materials into and out of the nucleus through nuclear pores.
What types of organisms have eukaryotic cells?
There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.
