Active transport requires energy because unlike osmosis and diffusion which are passive transport methods which sees where the particles are moving along the concentration gradient, in active transport, the particles are moving against the concentration gradient and as such energy through ATP is needed for the particles to be transported.
The kinetic energy of 6250 J equals 6250 J work-done in stopping the object in motion.
The given parameters;
- <em>Kinetic energy, K.E = 6250 J</em>
According to work-energy theorem, the work done in stopping a moving object is equal to the kinetic energy of the moving object.
Kinetic energy is the energy possessed by an object by virtue of its state of motion.
Work-done in stopping the object in motion = K.E = 6250 J.
Thus, we can conclude that the kinetic energy of 6250 J equals 6250 work-done in stopping the object in motion.

Answer:
New discoveries in the treatment of cancer do not only centre on conventional medicine. In our haste to get to grips with a cure for cancer, natural products may be overlooked and dismissed in the fight against such an aggressive disease.
In December, the Academy of General Dentistry reported that a new study had found that simply swishing green tea around the mouth halts the growth of new oral cancer cells and breaks down and kills existing oral cancer cells. The antioxidants (polyphenols) in the tea work to remove the free radicals or oxidants and prevent gene mutations, and as an added bonus, the polyphenols can kill cancerous cells without harming normal cells and inhibiting their growth. Similarly, a chemical found in tomatoes may prevent or treat oral cancer and one derived from soybeans has been found to shrink abnormal growths that lead to cancer. While these are not cures, their activity may in the future lead to therapies that compliment conventional treatment modalities.
Perhaps combining ancient remedies with Western scientific advances is the way forward to finding an effective cure for cancer. Combrestatin – a cancer-fighting drug made from the bark of an African tree – is performing with dramatic effects in tests. The active ingredient extracted from the bark attacks the blood vessels that grow with tumors, while leaving normal blood vessels alone.
1 hour I think.. correct me if im wrong <3
