Answer
Leech is parasite depend on blood sucking for feeding purpose. when attach to human body then it is difficult to detach them. however pouring salt on them is helpfull in detaching from the body. when salt is poured on their body surface, due to osmosis water come out from their body ,pH of their blood chane and all their metabolic process inside body is unbalanced or functionally abnormal as a result leech detach from the body.
Telomeres are regions that make up the end of each chromosome. These 5 nucleotide repeats help preserve the integrity of the DNA during replication. However, in each division, the telomeres shrink. Some scientists have seen in this mechanism a biological clock governing the aging of cells. Until now no one has shown a link between the two phenomena.
The size of the telomeres (the number of repetitions) varies from one individual to another at birth. At each replication cycle, the chromosomes shorten. This is because the enzyme responsible for its replication cannot copy the end of the chromosomes. It is estimated that 100 nucleotides decrease the size of telomeres by division in humans. When the telomeres become too short and before the genes are affected, or the chromosomes merge with each other, the cells stop their division and enter into senescence.
A single enzyme is able to extend the telomeres, telomerase. This enzyme is not active in somatic cells. However, there are somatic cells that are immortal, these are the cancer cells. They have lost control of their cell cycle and can divide indefinitely. This ability to multiply without limit is accompanied by the activation of telomerase.
Answer:
Car 1 will roll down the ramp and exert a force on car 2. The force experienced by car 2 is measured indirectly using t<u>he distance it travels or its speed
.</u>
. If the force increases, car 2 will travel <u>slower or farther</u> The independent variable, or what’s being manipulated in the experiment, is <u>the starting height of car 1 or the type of bumper attached to car 2
</u>
he dependent variable, or what’s responding, is <u>the distance car 2 travels or the speed of car 1
</u>
The height and starting position on the ramp are constants in this experiment.

Answer:
Yes
Explanation:
Hormone is responsible to mediate change in the cell by binding to the hormonal receptor present on the cell. So hormone only acts on the cells which have the specific receptor for that hormone.
One cell can have many receptors for a single hormone which defines the sensitivity of cell for the hormone which is responsible for generating appropriated cellular response in the cell.
So the number of receptors on the cell can contribute to different responses of cells having the same hormonal receptor. Every cell also have unique transduction pathway which is also responsible for different response of cell.
