Parasitism refers to the relationship between two organisms or species in which one organism lives in or on the body of the other.
The organism which lives on the body of the other is termed as the parasite while the other organism is termed as the host.
The parasites derive their nutrition from the host but they do not kill their host at once.
Examples may include tapeworm, hookworm, Plasmodium,flukes, fleas et cetera.
The tapeworm are the flat segmented flatworm that live as parasite in the intestine of the mammals. They derive their nutrition from the partly digested food of the host. It deprived the host of nutrients.
B. color, capacitance
C. resistance, current
D. distance, circumference
Answer:
Length and speed.
Explanation:
According to Faraday's law, the voltage induced in the conductor is equal to the product of magnetic field, length and speed of the conductor.
The formula to find the induced voltage in the conductor is:
ξ = Blv
Here, ξ= emf induced, B is magnetic field, l is the conductor length and v is the conductor speed.
From the above formula, it is clear that voltage of a conductor depends upon the length and speed of the conductor.
Thus, the correct answer is option (A)

Answer: "The synovial fluid in my joint capsule acts as a lubricant and helps the movement of the joint's articulating surfaces."
Explanation:
Synovial fluid is also called Synovia. It is produced by the synovial membrane. It is a thick liquid found in the cavities of synovial joints. It's function is to reduce friction by acting as a natural lubricant between the articular cartilage of synovial joints and allows ease of movement, they act as shock absorber and nourishment in the joints. Each of the joints contain synovial fluid.
