Answer:
C. Cancer cells lack contact inhibition
Explanation:
b. are typified by tweezers or forceps
c. have load at one end of the lever, fulcrum at the other, and effort applied somewhere in the middle
d. in the body can operate at a mechanical advantage or mechanical disadvantage, depending on specific location
Answer: d. in the body can operate at a mechanical advantage or mechanical disadvantage, depending on specific location.
Explanation:
A first-class lever is defined as the force in which fulcrum is present in the center and the load and effort on each side of the fulcrum. First class lever moves over a large distance to move the load to a smaller distance.
First-class lever can be operated at mechanical advantage or disadvantage that it can aid in work by changing the direction of the force and by increasing the efficiency. As the the fulcrum is between the load and the effort so the length of the effort arm divided by the length of the effort arm.
If the fulcrum is closer to the effort, it will operated at mechanical disadvantage and vice versa.
Example of first class levers includes scissors, a claw hammer, a see-saw and a weighing balance.
Hence, the correct option is D.
Answer:
The hydrogen bonds between water molecules absorb the heat when they break and release heat when they form, which minimizes temperature changes. Water helps maintain a moderate temperature of organisms and environments. Water takes a long time to heat up, and holds its temperature longer when heat is not applied. 3.

Secondary consumers must eat more often or consume more prey to obtain the same amount of energy as primary consumers.
Secondary consumers usually eat a smaller quantity of food than primary consumers because they obtain their energy from consuming other organisms rather than directly from photosynthesis.
This means that a significant amount of energy is lost as it is transferred up the food chain. For example, only around 10% of the energy stored in plants is transferred to herbivores, and only around 10% of that energy is transferred to carnivores.
This means that the higher up the food chain an organism is, the less energy is available to it.
Therefore, secondary consumers must eat more often or consume more prey to obtain the same amount of energy as primary consumers.
