Answer: The Organismal Theory teaches that the basic unit of life is the organism.
Explanation: The Cell Theory teaches that the cell is the basic unit of life while the Organismal Theory teaches that the basic unit of life is the organism itself.
B. New oceanic crust is formed at seamounts and spreads outward in all directions.
C. New oceanic crust is formed at deep-sea trenches, pushed away from the trench, and destroyed at midocean ridges.
D. New oceanic crust is formed in the middle of tectonic plates and then spreads outward in bands.
The answer is B. This occurs at mid-ocean ridges, where two tectonic plates are moving away from each other. As they move in opposite directions, the magma from the mantle below rises to fill the void/space left above. As the magma rises, it cools and forms a new crust. This volcanic activity continues as long as the tectonic plates are moving away from each other and new crust is formed spreading outwards from the ridge, with time.
The correct answer is option B that is neutrons.
The atomic mass refers to the mass of an atom of a chemical element articulated in atomic mass units. It is about the same to the number of protons and neutrons in the atom (the mass number) or to the average number permitting for the relative abundances of distinct isotopes.
The atomic mass of a single atom of an element is determined by supplementing the mass of protons and neutrons.
Atomic mass is calculated by the sum of number of protons and the number of
Further explanation:
The smallest particle that is the building block of matter is known as an atom. Most of the space in an atom is empty and its mass is concentrated inside a small region called the nucleus.
Protons, electrons, and neutrons are the three subatomic particles that are present in the atom. The sum of protons and neutrons are called nucleons because these are located in the nucleus of the atom. Electrons revolve around the nucleus in fixed orbital path. The positively charged subatomic particle is called proton. Neutron is a subatomic particle that has no charge. Electron is the negatively charged subatomic particle. The number of electrons is equal to the number of protons in a neutral atom.
An atom is written as , where A is the atomic mass or mass number, Z is the atomic number, and X is the letter symbol of the element.
The total positive charge is known as the atomic number. It is represented by Z and is also equal to the number of protons present in the nucleus of the atom.
Atomic mass is the total number of nucleons within the atomic nucleus. It is also known as the mass number. Protons and neutrons together are known as nucleons because these are located in the nucleus of the atom. So atomic mass is the sum of number of protons and neutrons in the nucleus of an atom. Hence option (B) is correct.
