You can essentially mix and match, not only that but there are so many, too, which accounts for the variety.
D
Paleontologists study and prove the change in form and functions of organisms throughout time in the fossil record.
Answer: Option C) The arrangement of atoms allows precise hydrogen bonding.
Explanation:
The individual hydrogen bonds between the base pairs confer stability to double helix of DNA.
The bases atoms take SPECIFIC POSITIONS or better still ARRANGEMENT, with Guanine pairing with Cytosine base atoms by three hydrogen bonds, while Adenine pair Thymine base atoms by two hydrogen bonds.
So, the arrangement of base atoms allows precise hydrogen bonding and hence STABILITY of DNA double helix.
Blood flows to the kidneys through the right and left renal arteries. Inside each kidney these branch into smaller arterioles.
The blood is at very high pressure and flows through the arterioles into tiny knot of vessels called the Glomerulus. These are located in the nephrons.
From the glomerulus the blood pressure drops and the blood flows into arterioles which coil around the nephrons. These in turn connect to a series of small veins. These vessels reunite and ultimately form the renal vein.
About one quarter of the total cardiac output (or total blood flow) circulates through the kidneys. This equates to just over 1 litre of blood every minute.
Hope this helps (:
Answer:
<h3>The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.</h3>
