Answer:
because they were eating different foods
Explanation: this led them to evolve to have different beaks depending on what type of food they were eating
Answer:
Be around their own species
Explanation:
So they can be able to reproduce the genes to the next generation
Any of the pairs of the hydrogen-bonded purine and pyrimidine bases that form the links between the sugar-phosphate backbones of nucleic acid molecules: the pairs are adenine and thymine in DNA, adenine and uracil in RNA, and guanine and cytosine in both DNA and RNA.
Answer:
<h2>
1. Ventromedial hypothalamus</h2><h2>
2. Lateral hypothalamus</h2>
Explanation:
Hypothalamus is the part of the brain which plays very important roles in the human body which includes the production of hormones, sexual control and controlling appetite.
Hypothalamus region is divided into many regions which contain their own nuclei and many reasons controlling the appetite which are lateral hypothalamus, paraventricular nucleus, ventromedial nucleus and dorsomedial nucleus.
The lateral hypothalamus is involved in producing action potential which stimulates eating whereas ventromedial hypothalamus produces impulses which reduce the hunger.
Thus, Ventromedial hypothalamus and Lateral hypothalamus are the correct answer.
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.
