The genes that control a trait come in pairs. The purpose of genes? is to store information
Answer:
One molecule of glucose has 6 atoms, as you can see in carbon's index. ( C6 ). In 20 molecules there will be 6⋅20 carbon atoms.
Explanation:
Answer:
The rock is heavier than water and when put into water it will sink.
Explanation:
Given data:
Mass of rock = 2.7 g
Volume = 1.1 cm³
Type of rock = ?
Solution:
From given data we can calculate the density of rock.
If the density of rock is higher than the density of water it means the rock is heavier than water.
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
d = m/v
d = 2.7 g/ 1.1 cm³
d = 2.5 g/cm³
density of water is 1 g/cm³. The rock is heavier than water and when put into water it will sink.
The working equation for this problem is average atomic mass
is equal to the summation of the product of relative abundance and mass of
isotope. In this problem, just subtract the % abundance of Ag-107 to 100. Thus
the % abundance of Ag-109 is 48.16.
