<h2>Answer:</h2>
The correct answer is option D which is substances will pass in and out of the cell in an uncontrolled manner.
<h3>Explanation:</h3>
- Cell membrane is outer organelle in the cell, it is responsible for the transport of materials into and out to the cell through osmosis and active transport.
- In the absence of the cell membrane, there will not be control of transport of a materials to the cell.
- Energy production is the task of mitochondria and food storage is the function of vacuoles.
- Photosynthesis takes place on the chloroplasts.
Ba stays as Ba+2 and Cl stays as Cl-
The pole varies in position on a yearly basis due to secular variation (or drift in Earth's magnetic field). Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Hello
We know that polar molecules' attraction is stronger than that of non polar ones; this can be a good basis for us to check the substances' polarity. Knowing that polar forces are stronger, we can eliminate all options referring to them as being the weaker force; that is, options C and A. Next, we know that stronger forces will result in lower volatility so we can eliminate option D. The answer is B, assuming the compound has an odor.
Answer:
See explanation.
Explanation:
Hello,
In this case, we could have two possible solutions:
A) If you are asking for the molar mass, you should use the atomic mass of each element forming the compound, that is copper, sulfur and four times oxygen, so you can compute it as shown below:
That is the mass of copper (II) sulfate contained in 1 mol of substance.
B) On the other hand, if you need to compute the moles, forming a 1.0-M solution of copper (II) sulfate, you need the volume of the solution in litres as an additional data considering the formula of molarity:
So you can solve for the moles of the solute:
Nonetheless, we do not know the volume of the solution, so the moles of copper (II) sulfate could not be determined. Anyway, for an assumed volume of 1.5 L of solution, we could obtain:
But this is just a supposition.
Regards.
