Answer: Microglia is a type of gllial cells that monitor health of neurons and can transform into special type of microphage to protect endangered neurons.
Explanation:
Gllial cells are cells found in the nervous system, they surrond the neurons and provide support and insulate them.
Types of gllial cells include, microglia, Schwann cells, satellite cells, ependymal cells, astrocytes and oligodentrocytes.
Microglia is a type of gllial cells than can change to special macrophages found mainly in the central nervous system. The maintain the health of the nervous system and protect endangered neurons. They also removed damaged neurons.

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:
The correct answer is (b) 1%
Explanation:
Represented in an ecological energy pyramid, the seals would be in the third position from the bottom as <em>secondary consumers</em>.
In this example, the <em>base of the pyramid </em>will be represented by the coconut palms, the primary producers, also known as autotrophs, which create their food by <em>taking their energy from non-living sources</em> of energy, like the sun.
The second level consists of primary consumers. Herbivores feed solely on <em>primary producers</em>, in this case, the coconut crabs.
The third level would be the secondary consumers, usually carnivores and omnivores, in this case, the seals.
In this example, as seals would be the secondary consumers located at the third level of the pyramid from the bottom, they will receive about 1% of energy.
I hope it helps!
