What are three ways energy is used by the organisms?

Answers

Answer:

Organisms use energy to survive, grow, respond to stimuli, reproduce

Explanation:

Three ways energy is used by the organism are food, nutrients, and sunlight.

What are living organisms?

Living organisms are those organisms that grow, adapt, and reproduce their young ones. Organisms need energy for their biological purposes. Organisms get energy from plants and other animals. This energy is used in the form of glucose.

Cellular functions require energy, which living things must obtain from food, nutrition, or sunshine. Energy is used in a cell for the transport, synthesis, and breakdown of nutrients and molecules.

Glucose and ATP are the two types of molecules that organisms primarily use for chemical energy. In the entire biological universe, both molecules are used as fuel.

Therefore, the energy is used by the organisms in three ways that are food, nutrients, and sunlight.

A cell’s digestive enzymes are enclosed in a membrane-bound organelle. How can these molecules function in the cell?

Answers

Answer:

A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.

Explanation:

Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily

-Calculate the fluid pressure at Piston A.
-Calculate the force exerted on Piston B.
-Which principle is being applied? What does the principle state?
Show all your work!

Answers

Answer:

80N

Explanation:

in both sides, pressure is the alwyays the same whatever the area is..

First we calculate the pressure at piston A:

P= F÷a

given that,

#F= 20N

#a=1m^2

P= 20÷1

P= 20 Pa.

At piston B:

pressure is the same = 20Pa

Area= 4m^2

P=F/a

F= P×a

F= 20 × 4

F= 80N

Answer:

C. Guanine

Explanation:

A pairs together with T, or U in RNA,

and C and G always pair together.

Answer:

The answer is C. Guanine

Explanation:

Pyrimidines always bond with purines.  Since Cytosine is a pyrimidine, it must bind with a purine, which can either be Adenine or Guanine.  However, Adenine has only 2 places for hydrogen bonding while Guanine has 3.  Since Cytosine also has 3, it would bind to Guanine.  GCAT is a useful acronym for remembering which binds to which.
