Answer:
Some enzymes require the addition of another non-protein molecule to function as an enzyme. These are known as cofactors, and without these enzymes remain within the inactive.

Answer:
menisci
Explanation:
Some synovial joints such as that of knees have crescent-shaped pads. These pads are made up of fibrocartilage and are present between the articular surfaces of the bones. These cartilaginous pads are attached to the fibrous capsule and are called articular discs or menisci.
The function of the menisci is to serve in shock absorption and minimize the wear and tear of the joint. Meniscus also allows the articulating bony surfaces to fit properly and facilitate an adaptable surface for combined movements. Meniscus serves to distribute the weight over a greater contact surface and thereby makes the joint stable. It also spreads the synovial lubricant across the articular surfaces of the joint.
Answer:
The correct option is BLOOD CALCIUM LEVEL.
Explanation:
The options attached to this question are given below:
A. Filtration membrane integrity
B. Systemic blood pressure
C. Blood calcium level
D. Renal artery/arteriole diameters
Kidney is an excretory organ, which functions by filtering waste products out of the blood. The rate at which the kidneys filter the blood depend on some factors; such factors include: water intake, systemic blood pressure, vasoconstriction, dehydration, filtration membrane integrity etc.
Blood calcium level does not have any effect on the rate at which the kidneys filter the blood.
Apples are drawn to a massive object, like the earth, and fall down under a gravitational constant. On the other hand, planets revolve around a more massive object under the same premise. It’s the same idea, just one follows a linear path, and the other has a uniform circular motion path because other forces are acting on it. In other words, the planets ARE still falling, but the sun is also pulled by them so they just keep dancing.
C. Precipitation fits the definition for “falling rain or snow”
