Some reminders are necessary:
Artery does not have valves, the blood pressure on it is very high, there is no risk of blood backflow, so it does not need valves
Arteries are vessels that transport blood from the heart to capillaries.
Veins are vessels that transport blood back to the heart from capillaries.
According to these reminders, you could conclude that:
A is false (no backflow in arteries)
C is false (no backflow in arteries)
D is false ( veins take blood to the heart)
so the right answer is B
Answer: Grazers
Explanation:
During early childhood kids often become grazers, eating small meals and snacking throughout the day instead of eating two or three large meals.
Grazing is a type of eating habits found mostly in early childhood whereby they consume, too often, little food( especially snacks) at a time. Although they might gain energy from snacking frequently, when a child is a grazer the following disadvantages about this eating personality are bound to occur:
- they will not be comfortable eating other healthy meals except snacks of which they are used to.
- they miss out to develope the natural rhythm of becoming hungry, eating and then feeling full because of the frequent eating habits.
