The principal function of thyroxine is to stimulate the consumption of oxygen and thus the metabolism of all cells and tissues.
Thyroxine is termed T4. It travels through the blood to the target cells and becomes converted to triiodothyronine or T3.
T3 is the active form of thyroxine. T3 enters the target cell's nucleus binding to genes responsible or involved in the metabolism of sugar in the body. T3 stimulates these genes and in so doing metabolism (conversion of oxygen and calories to energy) is carried out by the cell, which also results in generation of body heat.
A predator is an organism that hunts and kills prey for food
Answer:
Approximately 25 arteries would branch off
Explanation:
Aorta has a diameter of 2 cm, so area is pi x 1^2 = 3.142
In case of the artery, pi x 0.2^2 = 0.126
So dividing total area of aorta by total area of one artery, we get 3.142/0.126 = 25.021
Hence, about 25 arteries will be needed to carry the amount of blood that flows in the aorta vessel.
Nitrogen is so vital because it is a major component of chlorophyll
And it also is a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.
Answer:
Anatomical differences between men contribute to an increased risk of ACL injury.
The width of the intercondylar notch in women is smaller than in men.
The transverse area of the ACL is more difficult in men, which may be a smaller diameter of the ACL in women may be a risk factor for rupture.
Additionally the Angle Q (angle between femur and pelvis), whose normal value is 8 to 17 °, is consistently higher in women because on average, the woman's pelvis is wider and the femur shorter than in men. The existence of an increased Q angle increases the medial stress on the knee ligaments.
Finally, in female athletes, the menstrual cycle produces early changes in the synthesis of fibroblasts and procollagen type I in the ACL.
To prevent, the thigh muscles (quadriceps and ischia) and the twins must be specifically worked on. It is also necessary to train the proprioceptive mechanisms of reflex response.
