Medications can be tested on cell cultures instead of being injected into patients unnecessarily.
Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells.
So abiotic means nonliving, so the only abiotic option is B. the gravel on the bottom of the aquarium.
Answer:
Output force is 4.8 N
Explanation:
A pulley is a simple machine made of a grooved wheel with a rope or cable wrapped around it. Pulleys are used in the transmission of energy or motion.
The input force is also known as the applied force while the output force is the force exerted on an object by a simple machine.
The mechanical advantage of a pulley is the ratio of the output force to the input force.
Mechanical advantage = output force / input force
Substituting:
0.48 = output force / 10
Output force = 4.8 N
Answer:
D) resource partitioning.
Explanation:
Resource partitioning explains how species that are similar (in this case the two-spot and the three-spot avenger beetles) use their resources together (coexist). They live in the same community and use the same resources, but they don't push one another to extinction through competition. They use the same limiting resource at different time and thus, compete less with one another.
