The main difference between the Bohr model of the atom and the wave-mechanical model of the atom lies in the level of certainty of where the electrons are located is true.
<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.
It would be A detritivore
Answer:
In chemistry, a radical is an atom, molecule, or ion that has an unpaired valence electron. ... In living organisms, the radicals super oxide and nitric oxide and their reaction products regulate many processes
Explanation:
Explanation:
The given reaction is as follows.
![Ca + Cl_{2} \rightarrow CaCl_{2}](https://tex.z-dn.net/?f=Ca%20%2B%20Cl_%7B2%7D%20%5Crightarrow%20CaCl_%7B2%7D)
The number of elements on reactant side are as follows.
The number of elements on product side are as follows.
Therefore, the equation is completely balanced.
Thus, we can conclude that only one formula units of calcium chloride must be part of the products.
