<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.
Answer:
the answer is ClF3 on edge
Explanation:
Answer:
B) There are weak interactions between the CO2 molecules.
Explanation:
Carbon dioxide is composed of one carbon atom that is structured between two atoms of oxygen, they are bonded with double bond and the CO2 is symmetrical because of the arrangement of the bond between them.It is less electronegative than Oxgen, this gives Oxgen the ability to attract the electron to themselves, and there is no intermolecular existing within carbon dioxide other bands waal forces.Compounds that are gases under the condition of room temperatures, and pressure usually have have small molecules. and their molecules is usually have van der Waals forces acting between them and theses forces are weak.This allows carbon dioxide molecules to be able to move freely as a gas.
