Electrolytic cell is the type of a cell in which current drive a non-spontaneous redox reaction. Redox reactions are reactions in which the oxidation number of the reactants are changed. To change oxidation number, electrons must either be added to or removed from the reactants. However, to observe the law of conservation of mass, all the electrons removed from one reactant or atom must be added to another one, therefore, the number of species lost by one substance is equal to the number of electrons gained by the other.
Answer:
- law of superposition - Relative Dating
- important method for geologists - Absolute Dating, Relative Dating
- places historical events in their correct order - Relative Dating
- establishes how many years ago a given event took place - Absolute Dating
- radioactive decayused on rock strata - Absolute Dating
Explanation:
Absolute dating is an important process used by geologists. This process allows geoologists to determine the timing of a given factor in the environment. In other words, absolute dating allows a numerical age to be estimated for that factor or the age interval between factors, but without putting the factors' formation events in order. It is generally used to date chemical and physical elements present in artifacts and rocks.
Relative dating is also an important process for geologists, but it does provide a relative order of past events and does not provide a numerical age, like absolute dating. It is generally used to date rocks, surface deposits and fossils, often using the law of superposition as a basis.
Answer: 23
Explanation: One pair of the 23 chromosomes, known as sex chromosomes, determines at conception whether a fertilized egg will develop into a male or female. Today, human females have one pair of identical X chromosomes.
between 5.6 and 13 cm long
The appropriate response is a pigment component. Pigment are in charge of a large portion of the lovely hues we find in the plant world. Colors have frequently been produced using both creature sources and plant separates. A portion of the colors found in creatures has likewise as of late been found in plants.
