Flagella provide motility to a sperm cell, cilia act as sensory "antennae" in many cells and microvilli Increase a cell surface area
<h3>What is flagella, cilia and microvilli?</h3>
Flagella is a hair-like structure used by cells for locomotion or movement. The sperm makes use of flagella for locomotion.
Cilia is a hair-like structure that is found on the surface of organisms which are sensitive to touch.
Microvilli is a hair-like structure that is richly fortified with blood vessels found in areas for absorption. This is because it increases the surface area.

Answer:
Ligament
Explanation:
The ligament is a primary connective tissue which connects one bone to another bone in the skeletal system of humans. The ligaments are present is the ankles, knee, elbows and shoulders and in other joints.
The ligaments if broken cannot be regenerated and provides many functions like it provides guidance, input to the nervous system and provides stability to the bones and facilitates the movement.
Thus, Ligament is the correct answer.
1) yeast use anaerobic fermentation, because they do not need oxygen
2) aerobic respiration occurs in people
The answer to this question would be Rh incompatibility.
Rh or rhesus is a kind of antigen that can be found in human. Rh negative means that the mother doesn't have Rh antigen in her cell, so Rh antigen might be considered as "foreign body" and might activate white blood cell upon contact. If the father of the child has Rh positive gene, the child might become Rh positive and the child antigen can activate immune reaction and eliminated by mother white blood cells.
Rh incompatibility should be more severe in the second child since the mother white blood cells are more prepared than the first child(already sensitized).
