Explanation:
Intercellular communication is defined as the process of communication that occurs between the two cells of the same organism.
Now, these two cells relate which each other when a signal reception receives a single molecule at a distance that could be short or long which in turn produces a cellular response.
Thus, looking at the options, the correct answer is Option D.
Answer:
This is required answer.
Explanation:
Given that,
Thermal energy chemical change lab report
We know that,
Thermal energy :
When we rise a temperature of any substance then the molecules of substance moves fastly then the heat produced. It is called thermal energy.
Chemical change in the thermal energy :
When we heat a substance then the thermal energy increases and the molecules of substance moves fastly. That means the chemical bonds are break in reactants due to energy.
In products, The new chemical bonds are create due to energy.
For example ; The coal is burned then produced heats water and change it into steam.
Hence, This is required answer.
Answer:
B
Explanation:
I know im right I forgot some of the lessons cause this was still in grade 3 now Im grade 6....
Tin to Fluorine mass ratios:
1) For compound A:
38.5/12.3
= 3.13
2) For compound B:
56.5/36.2
= 1.56
The lowest whole number mass ratio is 2. It cannot be 1 because it is less than that required for compound B.
