B would be the correct answer
Food and drugs are often viewed as safer then what they really are, wether it’s on the package or by hearing it from other people. often food seems healthy like strawberry icecream although it is not, people only think it is because there is a fruit in the name. People think you just get drugs from bad people but you can go and get them at ur local store these are called over the counter medication and because of this people often think they are safe to take because you need no prescription. the best thing to do is talk to a doctor before getting them. also plan a healthy diet or just watch what ur eating. i hope this helped :)
The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them.
Hope this is helpful!
Order of steps are as follow;
1. In mechanical digestion, the teeth grind food and break it in to smaller parts.
2.Churning and enzyme pepsin break down protein in the stomach.
3. The pancreas releases the enzyme trypsin and chymotrypsin.
4. Amino acids are absorbed by the capillaries in the jejunum
5. Amino acids enter the bloodstream and are then circulated throughout the body.
Basically this says, food with source of protein is digested mechanically in your mouth, small pieces are then further broken down in the stomach through enzymatic action pepsin and those that are secreted by the pancreas, further absorbed by capillaries and circulated throughout the body via blood.
Huntington's disease is a disease that inherited autosomal dominant. That means you just need one allele to made it expressed. Let say that H is Huntington's allele and N is normal allele. In this case, the heterozygous father has (H x N) gene and the normal mother has (N x N) gene.
That mean
1. The father will have 50% chance to give normal allele and 50% chance to give H allele
2. The mother will have 100% chance to give N allele
Since you just need 1 H allele to got Huntington's disease, 50% the children will have Huntington's while 50% of them is normal
