Answer:
1. Attached
2. The have a 25% possibility of the disease and a 50% possibility of having the trait.
Explanation:
1. If J and K both carry the sickle cell trait, that means they are heterozygous for the sickle cell allele (Ss) where the sickle cell allele is recessive to the normal allele. The punnet square showing the possible genotypes of their potential offspring is shown in the attachment
2. The nurse would see that the genotypes possible are SS, Ss, or ss. SS would be a normal phenotype, Ss would be sickle cell trait, like the parents, and ss would have sickle cell disease. The ratios are 1 SS: 2 Ss: 1 ss. This means there is a 25% chance the child will be totally normal, a 50% chance they will inherit sickle cell trait, and 25% chance the child will have sickle cell disease.
Answer:
Description of the main functions of the circulatory system in your own words.
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
What are the main functions of the circulatory system?
The circulatory system delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood on different sides. The types of blood vessels include arteries, capillaries and veins.
