Answer:
The correct answer is 25% likely.
Explanation:
Phenylketonuria (PKU) is inherited in an <u>autosomal recessive pattern</u>, which means <u>both copies of the gene in each cell must have mutations</u> to express the disease.
If we let the allele causing PKU be “p” and the normal allele be “P”, the affected individual must have “pp” combination. If both parents are heterozygous, this means the have “Pp” combination and therefore the result in their progeny will be the following:
¼: PP (25%)
¼: pp (25%)
½: Pp (50%)
This pattern will repeat itself every time they try to have a child.
Explanation:
Limitations of Correlations
Correlation is not and cannot be taken to imply causation. Even if there is a very strong association between two variables we cannot assume that one causes the other. For example suppose we found a positive correlation between watching violence on T.V. and violent behavior in adolescence.
An important limitation of correlational research designs is that they cannot be used to draw conclusions about the causal relationships among the measured variables. Consider, for instance, a researcher who has hypothesized that viewing violent behavior will cause increased aggressive play in children

<span>Ab Roller Evolution is made of metal. It supports neck, head and upper body during workout. It is an upper body trainer: works chest and core. You can do push ups, sit ups, dips. By providing improved support, it reduces stress and strain on body.</span>
<span />Description above is from Amazon.
It is a good idea but has some problems with its design. There is no way to secure it on the floor during exercise. So it moves around when pushed against and would not provide support. A normal crunch will likely work out better.
Answer:
Both the respiratory and circulatory systems works in coordination in order to purify the blood.The heart continuously pumps blood and the lungs at alveolar sacs the CO2 and O2 get exchanged.Continuously through the diffusion.
From body parts the blood reaches at heart through Vena cava To right atrium,then from Right ventricle through pulmonary artery it reaches to lungs and get purified.Form there it again comes back to heart through pulmonary vein and again through Aorta it again reaches to the body parts.
Hope it helps....
