Materials pass to and from the bloodstream through the thin walls. They have walls that are only one endothelial cell in thickness. This delicate, microscopic vessel carries nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells. There, the nutrients are burned in the presence of oxygen (catabolism) to release energy.
At the same time, waste products such as carbon dioxide and water pass out of the cells and into these blood vessels. Waste-filled blood then flows back to the heart in small venues, which combine to form larger vessels called veins.</span>carbon dioxideGas (waste) released by body cells, transported via veins to the heart, and then to the lungs for exhalation.coronary arteriesBlood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle.deoxygenated bloodBlood that is oxygen-poor.diastole<span>Relaxation phase of the heartbeat.</span>
Answer:
Explanation:
Geneticists use letters to represent alleles of different characters.
(Alleles: one of the two or more alleles of a character.)
A single letter is used to represent both the alleles of a particular character.
A capital letter represents a dominant allele, while a small letter represents a recessive one.
<u>The letters do not just have one standard representation</u>. same letter can be used to represent different characters. However, the letters may relate to the allele. For example: the letter 'B' can be used to represent Brown eyes.
A.) Launch a satellite
Landing on the moon takes years to figure out. (How, when, what is the purpose, etc.) Capturing an asteroid is beyond difficult and would also take years to figure out how to do so.
Launching a space probe has yet to be done BUT we have had a satellite launched (hence how we get satellite images.)
Explanation:
It is true that the wings of the bee move very fast. The wings are smaller than their body and it is believed to be difficult for the wings to lift the whole body of the bee.
Sometimes, bees carry nectar and pollen with itself which again increases their weight. It has been found that the wings do not move up and down rather moves to and from. Since air is denser, it tries to push the air downwards and lift itself upwards.
Answer: hydrolysis of intermediate palmitoyl Co A ,with loss of labeled CoA.before reaching the matrix gives the answer
Explanation:
This is because when the labeled Coenzyme A of the Plamitate combines as Palmitoy-CoA with oxaloacetate to form intermediate (palmitoyl-CoA )in Citric Acid cycle:
CoA is hydrolysed with loss of the labelled CoA which returns to the cystosol. Therefore, the labelled CoA does not reach the matrix of the mitochondrial,but returns to the Cystosol.
Consequently, the CoA in the Cystosol will be labelled in palmitoylCoA and the one in the matrix of the liver mitochondrial will be non radioactive(,will not labelled).
