Answer:
If PKU is a recessively inherited disease, and the baby got it without either parent having it, then you can use a pedigree to figure out what kind of disease it is (whether autosomal or sex-linked). You can automatically cancel out sex-linked because we don't know the gender of the baby, so you can conclude that PKU is autosomal recessive in this family.
Does that make sense?
A frog heart has 3 chambers, 1 ventricle and 2 atria. One atrium (the right) receives deoxygenated blood from the frog's body (in the systemic circulation) and then pumped to the single ventricle wherein it will go to the lungs to be oxygenated. Another atrium (the left) received oxygenated blood from the lungs then pumped to the single ventricle wherein it will go to the systemic circulation. In the single ventricle, some form of mixing of the oxygenated and deoxygenated blood happens but since the frog is a cold blooded animal, the decrease in the concentration of oxygen is deemed superficial.
This advancement allows the frog to live on land using the lungs as the primary organ for oxygenation of the blood.
If you wanted to increase the rate of photosynthesis in a plant, you would develop a plant with many, broad leaves. This helps to get more sunlight. The correct answer is C, many, broad leaves.
The treatment of deadly diseases allows people to live longer which leads to increase in population.
<h3>Why would advances in medicine lead to population growth?</h3>
Due to advances in medicine, the death rates become slower which leads to increase in population. Medicines helps in the treatment of many diseases which causes death.
So we can conclude that the treatment of deadly diseases allows people to live longer which leads to increase in population.
