Answer:

Reactions require an input of energy to initiate the reaction; this is called the activation energy (EA).

Activation energy is the amount of energy required to reach the transition state.

The source of the activation energy needed to push reactions forward is typically heat energy from the surroundings.

For cellular reactions to occur fast enough over short time scales, their activation energies are lowered by molecules called catalysts.

Enzymes are catalysts

Answer:

Stem cells have the ability to divide through mitosis and produce unspecified cells. Stem cells can be developed into a required tissue because of their ability of differentiation.

Explanation:

A stem cell is a cell that is in an undifferentiated state. This means that it has not specialized in a specific type that carries out a specific function of that tissue, which does not imply that stem cells do not have their own function. The concept of stem cell is due to the ability to originate specialized cells from one or more tissues, depending on the degree of potency or plasticity it has. They are found in all multicellular living organisms. Their main characteristic is that by reproducing through the process of mitosis (they divide into two cells) they can form more stem cells or differentiate, that is, they become specialized cells, in such a way that they are essential for the renewal of cells in different tissues. and to repair them.

Soap molecules have a hydrophilic head and a hydrophobic tail. What happens when you put soap in water?

Kisachek [45]

I believe the correct answer from the choices listed above is option D. When you put soap in water, the hydrophobic tails cluster together and exclude water and the hydrophilic heads interact with water. Hope this answers the question. Have a nice day.

Hi ! I've been asked to think about a scientific innovation that I need to create and that doesn't exist yet ( it can also be so

harkovskaia [24]

Maybe you can do something like a self operating beaker that does all the measuring, pouring, and mixing for you. If that’s not interesting enough you can make it talk too, like a robot. Hope this helps!
