The cells of multicellular organisms, like you and me, become specialized for particular tasks and communicate with one another

to maintain homeostasis. Cells, tissues and organs all help to maintain the organism's internal environment. But what about a unicellular organism? Does it maintain homeostasis? If yes, what part of the cell plays a part in this process? A) Yes, the DNA directs what happens inside the cell at all times. B) No. Because these cells live in water, internal balance is automatic. C) Yes, the cell membrane along with the nucleus helps maintain internal balance. D) No. Internal balance in unicellular organisms is based on osmosis of water into and out of the cell.

A person tries to heat up her bath water by adding 5.0 l of water at 80c to 60 l of water at 30c. what is the final temperature
Sophie [7]
We can calculate the final temperature from this formula :

when Tf = (V1* T1) +(V2* T2) / (V1+ V2)

when V1 is the first volume of water = 5 L 

and V2 is the second  volume of water = 60 L

and T1 is the first temperature of water in Kelvin = 80 °C +273 = 353 K

and T2 is the second temperature of water in Kelvin =  30°C + 273= 303 K

and Tf is the final temperature of water in Kelvin 

so, by substitution:

Tf = (5 L * 353 K ) + ( 60 L * 303 K) / ( 5 L + 60 L)

     = 1765 + 18180 / 65 L

     = 306 K
     = 306 -273 = 33° C

Kipish [7]

Answer:

P= 138.6 atm or 1.4x10²

Explanation:

You will need to use PV=nRT to solve for P, pressure

Where the R constant is  0.08206 L atm mol^-1 K^-1

V is 1.2 L

T is temperature in kelvin, 273.15+25= 298.15

n is 6.8 mol

P*1.2=6.8*0.08206*298.15 ---> P*1.2=166.3700852 ---> P=166.3700852/1.2

P=138.6 atm

or 1.4x10²

Does gravity affect atoms?
stealth61 [152]
Gravity affects atoms the same way it affects all other matter. Every atom creates its own gravitational field which attracts all other matter in the universe. If you put a lot of atoms together, like in a planet or a star, all of the little gravitational fields add together, creating a much stronger pull.
