Answer:
Haemoglobin (Hb) is a protein present in red blood cells that transports oxygen and gives blood its dark/vivid red color. The amount of haemoglobin in the blood varies from person to person. Men's levels are often greater than women's. This is scientifically proven however, it is often but not all the time.
So, since the trait is eye color, let's use E to represent the dominant allele (brown) and e to represent the recessive allele (blue).
I've attached a Punnett square, but let me real quick explain how I set it up. We know that both parents are heterozygous, which means that they have one of each allele. So that gave us the two sides. Then I filled in the boxes (I assume you've leaned how to do this, if message me and I can explain it).
Looking at the results we can see that 1/4 of the offspring are EE, 1/2 are Ee, and 1/4 are ee. Since the blue allele (e) is recessive, it'll only be expressed if no dominant brown alleles (E) are present. Therefore, only the ee genotype will exhibit blue eyes. So, 1/4 or 25% of the offspring will have blue eyes.
Hope that helps! If you need clarification or anything feel free to message me :)
Answer:
Explanation:
Apart from Patricia's concern for her physical appearance and the weight she knows she'll likely gain as her pregnancy progresses, the dietitian will likely advice her not to gain too much weight because apart from her "physical appearance worries", gaining excessive while pregnant can also raise one's risk for birth complications such as C-section delivery and even premature birth.
In addition, the dietitian will likely offer Patricia more guidelines or tips such as:
****Commencing pregnancy at a healthy weight ( between 25 to 35 pounds), gaining more if underweight or gaining less if obese or overweight.
****Eating moderately but often, focusing on small, frequent meals that are high in lean proteins, fruits and vegetables.
****Drinking enough water ( about ten 8-ounce glasses of water) daily as this helps to aid metabolism and digestion as well as constipation prevention while preventing dehydration.
****Learning how to combine something healthy with less healthy cravings in the event of cravings for less healthy foods
**** Taking exercises such as walking very seriously as it helps to burn a great deal of excessive calories
**** Maintaining a recommended weight region at various stages of the pregnancy which will be in the best interest of mother and child
In a controlled experiment, the control group is compared with an experimental group.
Explanation:
A set of variables or data is considered as the control group that remains fixed or constant in its normal usual state; while all the other variables or data are identical with this control group, except one independent variable at a time. This is to observe the changes when that one variable is allowed for variations at a time.
This independent variable which undergoes changes is in the experiment group while the remaining constant group is the control group. The dependent variable changes with changes in the independent variable.
By comparing the control group against the experimental group, uncertainty in results are avoided.
