What is the difference between Active and Passive Transport?
tester [92]

Answer:

Active transport moves molecules and ions from lower concentration to higher concentration, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.

Explanation:

Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.

Help, I don't get this
Evgen [1.6K]

Answer:

Letter A represents the greatest potential energy.

Letter C represents the least potential energy.

Letter C represents the greatest kinetic energy.

Letter A represents the least kinetic energy.

Letters A and C represent an equal amount of both potential and kinetic energy.

Explanation:

Potential energy is a put away energy that relies on the overall situation of different pieces of a framework. A spring has progressively potential energy when it is packed or extended. A steel ball has more potential energy raised over the ground than it has in the wake of tumbling to the Earth. In the raised position it can do more work. Potential energy is a property of a framework and not of an individual body or molecule; the framework made out of the Earth and the raised ball, for instance, has progressively potential energy as the two are more distant isolated.\

Kinetic energy is a type of energy that an article or a molecule has by reason of its movement. In the event that work, which moves energy, is done on an item by applying a net power, the article accelerates and along these lines increases kinetic energy. Kinetic energy is a property of a moving item or molecule and depends on its movement as well as on its mass. The sort of movement might be interpretation (or movement along a way starting with one spot then onto the next), turn about a pivot, vibration, or any blend of movements.

In this lab, we'll be using PCR to make many copies of a small region of your personal DNA genome. It is a very bad idea to touc
Luden [163]
Sounds like a trick question.

Maybe not. contamination is easy, but gloves are a barrier between other organic material on yourself (such as what you ate for lunch) and what you are testing.

Other than the fact your DNA will be different than another person’s DNA, if we assume you are theoretically free of debris of any kind, then your DNA would test the same always.

Note: any contamination after purifying extract for a small sequence can give false positives. There are repeat sequences possible that would interfere if you are testing a small enough sequence.

I hope that helps!
