I think the correct answer from the choices listed above is option C. There would be 150 sodium ions that will be transported across the cell membrane.  Each ATP molecule aids in moving 3 Na+ across the membrane. So, 50 times 3 is equal to 150.

Heredity is defined as
AnnyKZ [126]

Answer:

B.

the passage of genetic instructions from one generation to the next generation.

These are called genes. One mate reporduces with another made and the genetic buildup merges 50 % and 50% with genetics(if it's meiosis), or DNA codes from the parents to the offspring that then possess some of the genes. That shows heridity.

3. Rationality- he does not believe in superstitions and think that everything has a scientific explanation 
4. Critical Mindedness & Correct Judgement- he does not easily jump to conclusions but tries to verify his results by (if possible) repeating the experiment 
5. Intellectual Honesty- does not alter his observations and writes the correct observations he has seen

How many stereoisomers are possible for 1 2-dichlorocyclopentane?
slega [8]
<span>There are only three stereoisomers of 1,2-dimethylcyclopentane. As there are only two chiral carbons, so the maximum number of stereoisomers is 4, but two are the same meso-compound which means that there are only 3.</span>

A 100.0mL bubble of hot gases at 225 C and 1.80 atm escapes from an active volcano, what is the new volume of the bubble outside
Inessa05 [86]
<h3>Answer:</h3>

112.08 mL

<h3>Explanation:</h3>

From the question we are given;

  • Initial volume, V1 = 100.0 mL
  • Initial temperature, T1 = 225°C, but K = °C + 273.15

thus, T1 = 498.15 K

  • Initial pressure, P1 = 1.80 atm
  • Final temperature , T2 = -25°C

                                     = 248.15 K

  • Final pressure, P2 = 0.80 atm

We are required to calculate the new volume of the gases;

  • According to the combined gas law equation;

\frac{P1V1}{T1}=\frac{P2V2}{T2}

Rearranging the formula;

V2=\frac{P1V1T2}{T1P2}

Therefore;

V2=\frac{(1.80atm)(100mL)(248.15K)}{(498.15K)(0.80atm)}

V2=112.08mL

Therefore, the new volume of the gas is 112.08 mL
