Answer 1

Answer:

The smallest structural unit of an organism that is capable of independent functioning, consisting of one or more nuclei, cytoplasm, and various organelles, all surrounded by a semipermeable cell membrane. A small enclosed cavity or space.

Momentum in simple terms can be defined as mass in motion. If the definition is for your assignment or work: It is the product of mass and velocity which refers to the quantity of motion that an object has. Momentum = mass * velocity.

Myopia is a condition in which visual images come to a focus in front of the retina of the eye, resulting in defective vision of distant objects.

Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. ... The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties.

Answer 2

Answer:

• Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature.
• Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.
• In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If m is an object's mass and v is its velocity
• Myopia, or short-sightedness, occurs when the eyeball is too long so it affects how the cornea and lens focus. This means objects in the distance appear blurry because light rays are focusing at the front of the retina rather than directly on its surface. ... The eye condition is also more common in some demographics.
• Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. ... The first part of his theory states that all matter is made of atoms, which are indivisible. The second part of the theory says all atoms of a given element are identical in mass and properties.
