Answer: The correct answer is Option B.
Explanation:
Prokaryotic cells are defined as the cells which does not contain any membrane bound organelles nor they contain nucleus. They are single-celled organisms. For Example: Bacteria, archaea
Eukaryotic cells are defined as the cells which contain membrane-bound organelles. These cells also contain nucleus and also they have DNA which is contained in the nucleus. They can be single-celled or multi-celled organisms. For Example: Animal cells, Plant cells.
Archaea and cyanobacteria are the examples of prokaryotic cells and thus, will not contain nucleus or any membrane-bound organelles.
Hence, the correct answer is Option B.
The cells contain a nucleus and membrane-bound organelles is eukaryotic.
Option B is correct.
Eukaryotic cells are the most complex cells and contain a nucleus and membrane-bound organelles. Prokaryotic cells, archaea, and cyanobacteria do not have a nucleus or membrane-bound organelles.
The cells that contain a nucleus and membrane-bound organelles are eukaryotic cells \Prokaryotic cells including bacteria and archaea lack a nucleus and membrane-bound organelles. Cyanobacteria are a type of prokaryotic bacteria, so they also lack a nucleus and membrane-bound organelles.
Therefore option B is correct

b. because the warmer air allows the particles to be free from gravitational forces
c. because the heat liberates the potential energy inside each molecule eliminate
d. because the warmer air is less dense and particles can move more
Answer: Option (a) is the correct answer.
Explanation:
When temperature of surrounding atmosphere around the tire increases then it will lead to increase in the kinetic energy of molecules.
Due to increase in kinetic energy of molecules there will be more number of collisions between the air molecules that are present inside the bicycle tire.
Hence, it means heat has been transferred from the surrounding atmosphere to the molecules inside the tire.
Thus, we can conclude that the air molecules inside a bicycle tire speed up as the temperature gets warmer because the heat is transferred to the molecules and gives them more kinetic energy.
The process in which a substance changes from a gaseous state to a liquid state is condensation
hope this helps!!!
Answer:
Condensation is the change of state from a gas to a liquid
An atom of titanium with atomic number 22 and mass number 49 contains 22 protons, 27 neutrons, and 22 electrons.
An atom of titanium has an atomic number of 22 and a mass number of 49. The atomic number represents the number of protons in an atom, so there are 22 protons in this titanium atom. The mass number of an atom is the sum of its protons and neutrons.
Since the atomic mass is 49, and the atomic number is 22, we can subtract the atomic number from the atomic mass to find the number of neutrons. In this case, there are 27 neutrons in the titanium atom. If the titanium atom is neutral, it means it has an equal number of protons and electrons. Since there are 22 protons, there are also 22 electrons in the atom.
