Answer:
Muscle tissue originate from mesoderm (one of the three germ layers). Muscle cell are made up of fibers called myofibrils.
Explanation:
Worker bees eat the left over polin and nectar left by the honey bees.
This would be an example of overproduction. The frog lays thousands of eggs, which is more than it needs, or would need in perfect conditions.
Explanation:
The major blood vessels that are connected to the heart include the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs, where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart) and the coronary arteries (which supply blood to the heart muscle).
To calculate the energy offered from food, multiply the number of grams of protein, carbohydrate, and fat by 4, 4, and 9, respectively.
Then add the results together.
Given: 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day.
500 grams x 4 kcal/g = 2000 kcal
30 grams x 4 kcal/g = 120 kcal
75 grams x 9 kcal/g = 675 kcal
= 2795 kcal
From this data, you can calculate the percentage of k calories each of the energy nutrients give to the total.
Solution:
2000/2795 * 100% = 72% from carbohydrates
120/2795 * 100% = 4% from protein
675/2795 * 100% = 24% from fat
Total: 100%
