1. What is energy?
eduard
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.

Elena-2011 [213]
B. Mutations cause a person's body cells to divide uncontrollably. There isn't a signal for cells to stop dividing, so this can cause cancer because cancer cells won't stop dividing without this signal.

Why do plants have a cell wall and animals cells don’t?
algol [13]
Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury. Other than that, it helps to keep the plant turgid so that it can stay firm and upright. Because when it enters a high water potential solution, as water moves in, the water exerts turgor pressure on the cell wall and the cell wall thus exerts an opposing pressure to keep water out. Hence cell wall is needed for the plant.

On the other hand, animal cells do not need to keep the structures, as they have the skeletal system to protect the organs and cushion them against any
external injuries.

I hope that helped

Approximately 90% of human cancer cells exhibit significant levels of telomerase. Does this mean that telomerase is an oncogene?
alukav5142 [94]

Answer:

No, telomerase is not an oncogene. It prevents the senescence that would occur due to shortened telomeres, but the cell proliferation might still be mitogen-dependent.

Explanation

telomerase is not responsible for causing  deregulation while oncogenes cause deregulation .

Telomeres length shorten after the cell division which stops them to divide again and cell die.

Telomerase prevents this decline in some kinds of cells, including stem cells, by lengthening telomeres, and the hope was that activating the enzyme could  prevent senescence.
