Answer is: number of neutrons is different.
Isotopes are chemical elements with same atomic number, but different mass number (different number of neutrons).
For example, hydrogen (H), besides deuterium (mass number 2) and tritium (mass number 3), has isotope protium (mass number 1).
Atomic number is unique and defines an element. Isotopes of an element have same atomic number (same number of protons in nucleus).
Atomic number (Z) is total number of protons and mass number (A) is total number of protons and neutrons in a nucleus.
Isotopes are variants of an element that have the same number of protons but different numbers of neutrons in their atomic nuclei. This difference in neutron count gives each isotope a unique mass number.
1. Mass Spectrometry: Mass spectrometry is a technique commonly used to identify and measure the abundance of isotopes in a sample. It works by ionizing atoms or molecules and then separating them based on their mass-to-charge ratio.
2. Nuclear Magnetic Resonance (NMR) Spectroscopy: NMR spectroscopy is another powerful tool for distinguishing isotopes. It exploits the magnetic properties of atomic nuclei to determine their local environment within a molecule.
3. Radioactive Decay: Some isotopes are radioactive, meaning they undergo spontaneous decay over time, transforming into other elements or isotopes.

Answer:
it is also know as biological diversity
Explanation:
it refers to the varieties or various forms of plants and animals species
It is totally not batholith, It is written in the section that it is Extrusive.
The phenomenon that naturally warms the earth's lower atmosphere and surface is called the greenhouse effect.
Put me as Brainliest!!!
The three primary sources of carbon dioxide (CO2) in the atmosphere are the respiration of organisms, the burning of fossil fuels, and deforestation or land use changes.
Carbon dioxide (CO2) is a type of gas that naturally exists in the atmosphere. It is primarily released from three key sources, which include:
The three primary sources of carbon dioxide (CO2) in the atmosphere are the respiration of organisms, the burning of fossil fuels, and deforestation or land use changes.
The three primary sources of carbon dioxide (CO2) in the atmosphere are the respiration of organisms, the burning of fossil fuels, and deforestation or land use changes.
Yet due to human activities like industrialization and deforestation, the amounts of CO2 in the atmosphere have been increasing at an unprecedented rate, leading to global climate change.

Answer:
37.18°C.
Explanation:
where, Q is amount of heat absorbed by water (Q = 5.75 x 10⁵ J).
m is the mass of water (m = 2190 g).
c is the specific heat capacity of liquid water = 4.18 J/g°C.
ΔT is the temperature difference = (final T - initial T = 100.0°C - initial T).
∴ Q = m.c.ΔT = 5.75 x 10⁵ J.
5.75 x 10⁵ J = (2190 g)(4.18 J/g°C)(100.0°C - initial T)
∴ (100.0°C - initial T) = (5.75 x 10⁵ J)/(2190 g)(4.18 J/g°C) = 62.81°C.
∴ initial T = (100.0°C - 62.81°C) = 37.18°C.
