Food chains don’t have infinite links, because only about 10% of energy is passed upwards in trophic levels. So a mouse could eat 10 grasshoppers, but a hawk would need to eat 100 mouses to get the same energy
A. Turner syndrome.
Turner syndrome is a type of aneoploidy called monosomy, which causes the person to be born with only one X chromosome with no extra Y or X.
I believe, for the artery, they have, an open, circular lumen an a thick media
Veins on the other hand, have somewhat collapsed lumen and a thinner media. Arteries are blood vessels that carry blood out of the heart to other parts of the body, all arteries carry oxygenated blood except the pulmonary artery which carries deoxygenated blood from the heart to the lungs. Veins carry blood from other body parts to the heart, all veins carry deoxygenated blood except the pulmonary vein which caries oxygenated blood from the lungs to the heart.
Answer:
The correct answer is - 130 kDa, 82 kDa, 45 KDa.
Explanation:
In the question given is there are 4 subunits in protein omicron in which two subunits are - 65 kDa and the other two subunits are - 85 kDa and 45 kDa.
So the size band would be in absence of beta-mercaptoethanol which is very essential to break down disulfide bonds that held together these subunits:
Size band = 65 KDa + 65 KDa
= 130 KDa (one band) (
65+65=130),
82, 45 as without beta mercaptoethanol disulfide bond is not broken
.
Thus, the correct answer is - 130 kDa, 82 kDa, 45 KDa.
The answer is; B is younger than D
In sedimentary rocks, the bottom layers are older that overlaying layers. This is because sediments are placed on top of each other by surface runoffs to ocean beds. Therefore, the first sediments to be deposited will always be towards the bottom as more and newer ones are brought in and deposited.
