Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.

The inter neuron helps in communication between motor or sensory neuron and the nervous system.

babymother [125]

Answer;

-Glycogen

The organic molecule called glycogen is formed of branched chains of sugar units.

Explanation;

-Glycogen is a branched polysaccharide of glucose that serves as a form of energy storage in humans, animals, fungi, and bacteria.

-In humans, glycogen is made and stored in liver and muscle cells. Muscle cell glycogen is broken down into glucose, and liver glycogen is broken down into glucose as a circulating energy source glucose for use by the body.

-Glycogen is accumulated in response to insulin and broken down into glucose in response to glucagon. It plays a major role in maintaining the blood-glucose levels, which is vital since some organs in the body such as the brain purely depend on glucose for energy.

Other options, like option A, cannot be true because many complex organisms have fewer chromosomes than other organisms. For example, there are many simple plants which have more number of chromosomes than the complex humans.
