Answer: The brain is an organ, and a very unusual and complex one at that. It plays a role in every one of our functions, controlling many organs, our thoughts, memory, speech, and movements.
Explanation:
An atom's electrons have a great effect on how ''chemically reactive atom is".
An atom is a small particle that can exist or be combined with other atoms which forms a molecule. An atom is a chemical element.
Hope this helps :)
Answer:
the volume of CHCI3 = 7.87 ml
the volume of CHBr3 = 12.13 ml
Explanation:
From the given information:
We all know that 1 g/cm^3 = 1 g/ml
The density of boron = 2.34 g/ml
The Volume of the liquid mixture = 20 ml
Recall that:
Density = mass/volume
Mass = Density × Volume
Mass = 2.34 g/ml × 20 ml
Mass = 46.8 g
Suppose the volume of CHCI3 be Y and the Volume of CHBr3 be 20 - Y
Then :
Y (1.492) + 20-Y(2.890) = 46.8
1.492Y + 57.8 - 2.890Y = 46.8
- 1.398 Y = -11
Y = -11/ - 1.398
Y = 7.87 ml
Therefore, the volume of CHCI3 7.87 ml
the volume of CHBr3 = 20 - Y
= 20 - 7.87
= 12.13 ml
Answer:
This type of mutation occurs when one or more base pairs are added to the gene sequence: insertion
This type of mutation occurs when one or more base pairs take the place of other base pairs in the gene sequence: substitution
I think the definition of planetary differentiation is the separation of materials based on density. It involves separating out different constituents of a planetary body as a result of their physical or chemical characteristics, such that each body develops into compositionary distinct layers; such that the denser materials of a planet sink at the center while less dense materials rise to the surface.
