To summarize, food intake is influenced by metabolic activity in hypothalamic neurons and elsewhere; by hormones that signal the body's fat content to the brain; and by other homeostatic-need situations such as low blood glucose. All of these represent instances of negative feedback.

Answer:
Analyzing Childhood Obesity Trends
A graph titled Childhood and Adolescent Obesity Rates shows years on the horizontal axis and percent on the vertical axis. Obesity increased from 5% to 14% in children ages 2 to 5. Obesity increased from 4% to 20% in children ages 6 to 11. Obesity increased from 6% to 10% in children ages 12 to 19.
Which obesity trends are represented in this graph? Check all that apply.
1 Obesity rates for children aged 2–5 doubled.
2 Obesity rates for all age groups increased.
3 Obesity rates for individuals aged 12–19 increased the most.
4 Obesity rates for children aged 6–11 increased the least.
5 More than 15% of all children aged 6 and over were obese in 2008.
ANSWER : 1 Obesity rates for children aged 2–5 doubled , 2 Obesity rates for all age groups increased , and 5 More than 15% of all children aged 6 and over were obese in 2008.
Explanation:
Answer:
Arteries carry blood away from the heart; veins carry blood back to the heart.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole: in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The best description for arteries and veins is that arteries carry oxygenated blood away from the heart to other parts of the body such as brain, lungs, tissues, etc; veins carry blood that is low in oxygen content back to the heart.
