What is Sickle cell anemia?
Sickle cell is an autosomal recessive trait of humans that arises through mutation in normal gene. The gene for this trait is found in recessive form and you need two copies of the gene - one from father and one from mother- to have the trait expressed. If the trait is expressed it causes a disease called sickle cell anemia.
People with the sickle cell anemia disease have red blood cells of crescent or sickle shape. The red blood cells of this shape can cause many complications in body. They get stuck in blood vessels and cause pain. They also die quickly and make a person anemic (pale).
Probability to have a child with sickle cell anemia:
If a mother is normal but a father is carrier for the trait, then the situation will be as:
Here N indicate normal allele, S indicate allele for sickle cell anemia.
Mother ˣ Father
NN NS
Gametes: N N N S
Offspring: NN NS NN NS
50% : Normal
50% : Carrier
0% : Sickle cell anemia
It means that 50 % kids will be normal and 50% will be carrier for the trait and none of the offspring will have disease Sickle cell anemia.
However, those who are carriers can carry the disease to the next offspring if they are married to a carrier or a person with sickle cell anemia.
Answer:
When there is a constant unbalanced force applied in the opposite direction as the motion, speed will <u>decrease</u> and acceleration will <u>increase</u>.
Explanation:
An opposing force should slow something down, decreasing the speed, and acceleration is just change in speed or direction.
Have a great day!
Extension or straightening of the elbow stops when the proximal end of the ulna engages the olecranon fossa of the humerus.
Explanation:
Extension of the elbow is the straightening of the forearm or bringing it back to its anatomical position by the triceps brachii and the anconeus muscles.
The elbow joint, a hinge type of joint, is formed at the conjunction of humeral distal end with the ulnar proximal end.
Olecranon process is a structure at the ulnar distal end which fits exactly into the olecranon process at the humeral proximal head with the arm in extended position.
Olecranon fossa is a <em>triangular</em> depression or fossa which is deep in the posterior humerus. So the range of motion due to extension of forearm terminates or limits at the contact of the ulnar olecranon process with that of the humeral olecranon process at the olecranon fossa.
I’m pretty sure Stomata is required and water is necessary too
