The lower case letter represents the recessive allele.
Atmospheric oxygen DID increase after the evolution of photosynthetic prokaryotes. So It is true.
Answer:
B, 2.22×10^22 molecules
Explanation:
Given PV=nRT, n=PV/RT
n=103.7×1.0/8.314×(65+273.15)
= 0.0368858... moles
Given n= number of particles/avogadros number
number of particles=n×avogadros number
number of particles = 0.03688...×6.02x10^23
= 2.22×10^22 molecules
Answer:
You can view more details on each measurement unit: molecular weight of NaCl or grams This compound is also known as Sodium Chloride. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles NaCl, or 58.44277 grams.
Answer:
The energy needed to split an atom into separate protons, neutrons, and electrons
Explanation:
The equation E = MC^2 is developed by Einstein’s Special Relativity Theory
where,
E = Energy
M = mass
C = speed of the light
The energy should be measured in Joules i.e J
The mass should be measured in Kilogram i.e Kg
And, the speed of the light should be measured in meters per second i.e ms-1
The C should be squared
Now the energy is required to divided into three particles i.e protons, electrons and neutrons
It also needs to allocate the nucleus into distinct protons and neutrons that we called binding energy of nuclear
And if the energy is required to take off an electron from an atom we called the energy of ionization
And if the energy is required to add an electron to an atom so we called it affinity of electron
