8. Arteries carry oxygenated blood from the heart to the rest of the body, while veins carry deoxygenated blood from the body, back to the heart. Arteries are thick and muscular, while veins aren't as thick, and they have valves.
Answer: The probability is 100%.
Explanation: The chromosome X is related to gender. A man carries two different chromosomes (XY) and a woman carries two similar chromosomes (XX). The offspring of a couple will inherited:
- If it is a boy, he inherites the chromosome Y from his father and X from his mother;
- If it a girl, she inherites X from her father and X from her mother;
In the question, the woman is color-blind, which means she carries the recessive alleles: 
The man, on the other hand, is normal, so his X-linked genotype will be:
.
Now, since they have a daughter, she inherited her double X from each of her parents, which means she inherited one
from her mother and one
from her father.
So, the daughter's genotype can only be heterozygotic 
in other words, the probability is 100%.
When the ride is at the top of its pole, it has all potential energy. When it is in the middle, at 34 meters, it has 50% potential energy and 50% kinetic energy. When the ride is almost at the bottom, it has kinetic energy that turns into potential energy as it reaches the end.
Pharyngeal constrictor muscles (superior, middle and inferior)
The pharyngeal constrictor muscles are a group of muscles that form the lumen of the pharynx. After you swallow, an act that you have control, it starts a involuntary contraction by these muscles to propel the bolus downwards.
"Grandmother cells" are mostly closely associated with specificity coding. Specifity coding is the representation of particular objects in a particular environment by the firing of neuron that are tuned to respond specifically to that object. Single cells fires only in response to the presence of a particular face say a grand mother but no response to any other face.
