The standard unit of measurement is meter; hence the answer is meter. The distance between two cities is usually measured in kilometer but the standard unit is meter.

36 inches make one yard. One Feet is made up of 12 inches. One-inch equals to 25.4 mm.

One Nautical mile consists of 1.852 Kilometers. This unit is often used in air and water navigations.

Such huge distances are measured in Light years. One light year is the distance travelled by light in one year.

Atom is the basic unit of life. A molecule is a compound made up of 2 or more atoms held by chemical bonds. The mixture is a combination of pure substances in a ratio. Ion is either positively or negatively charged.

Dalton’s atomic theory couldn’t explain gaseous volumes, because as per his view, different elements have different mass but this isn’t true. This is explained by Gay lussac’s law. This is one of the major limitations of Dalton’s atomic theory.

According to Dalton’s Atomic Theory, All atoms of a given element have identical properties, including identical mass. The reason behind this is that they belong to the same element (here “they” is about atoms).

The axonal membrane of the neuron or nerve cell is semi-permeable in nature. At resting membrane potential, the membrane is permeable to potassium ions but nearly impermeable to sodium ions.

A nerve impulse is also known as an action potential. It changes the resting membrane potential as it reverses the polarity of the axonal membrane. It becomes permeable to sodium ions and leads to its rapid influx.

A synapse is present between two adjacent neurons. The pre-synaptic membrane of one neuron, the post-synaptic membrane of the next neuron and the synaptic cleft make up the synapse.
