Answer:
circular folds
Explanation:
The movement of food in the body's alimentary canal <em>(the passage of food from the mouth towards the anus) </em>is aided by "peristalsis."
"Peristalsis" is an involuntary movement of the circular and longitudinal muscles found within the digestive tract. This movement occurs in the <u>esophagus, stomach and small intestine.</u>
Along the<em> jejunal intestinal wall</em> are the "circular folds." These folds are thick and stretches towards the "lumen." They function as speed bump control by slowing down the food passage and increasing the surface area necessary for <em>absorption</em>. After being absorbed, they will then be moved forward toward the large intestine.
So, this explains the answer.
Answer:
False
Explanation:
Prokaryotic cells lack a membrane enclosed nucleus and organelles.
Answer:
To conclude, you cannot prove a hypothesis because you can never generalise the results to the whole population and foresee the results will always be the same in the future. You can however, reject the null hypothesis consistently, through statistical hypothesis testing so that the theory becomes highly likely to be true, but not proven.
Explanation:
Answer:
flexion - depression
extension - elevation
adduction - medial rotation
abduction - lateral rotation
Explanation:
Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.
Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.
Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.
Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.
