       A muscle that moves the esophagus into line with the pharynx during swallowing
       A muscle that moves the trachea out of line with the pharynx during swallowing
       A flap that flips down to cover the entry to the trachea during swallowing

Question 5.5. (TCO 5) Regarding the amount of energy consumed versus the amount of energy used, what would you recommend to a friend who has a BMI of 20 to change to a normal BMI? (Points : 2)

       Take in more calories by eating than are burned by physical activity.
       Burn more calories by physical activity than are taken in by eating.
       Take in the same amount of calories by eating compared to that which is burned by physical activity, because they are already at a normal BMI.
       Weight gain is not related to the amount of calories taken in compared to the number of calories burned by physical activity.

       capillaries.
       venules.

Question 7.7. (TCO 5) What is one way in which the cardiovascular system of a mammal is different than that of an arthropod, such as an insect? (Points : 2)

       The heart of the mammal pumps blood into arteries, whereas the insect heart does not.
       Veins send blood to a mammal’s lungs, whereas insect veins send blood to the heart.
       A mammal’s blood is always contained inside vessels, whereas an insect’s blood sometimes leaves the vessels.
       A mammal has a heart to pump blood, whereas an insect does not have a heart.

1. (TCO 5) Spiders are (Points : 2)

       herbivores.
       filter feeders.
       carnivores.
       omnivores.

1. Carnivores

(Solution: Insects are predatory animals and eat insects and other spiders)

2. ingestion, digestion, absorption, and elimination

(Solution: Ingestion (chewing in mouth, food is broken into smaller particles), digestion (in stomach digestion with digestive enzymes), absorption (in intestine absorption occurs), and elimination (in the form of urine via urinary system, faeces from digestive system, gases from respiratory system etc.)

3. The digestive system of a bacteria has NO opening (Solution: Bacteria is an unicellular prokaryote, a single cell performs all function, there is not separate digestive system or any kind of openings .)

4. A flap that flips down to cover the entry to the trachea during swallowing (Epiglottis is a flap at the base of tongue , it prevents entry of food in respiratory track.)

5. Take in the same amount of calories by eating compared to that which is burned by physical activity, because they are already at a normal BMI.

(The normal BMI range is 18.5 to 24.9, therefore BMI 20 is normal and need not to take more calories)
