The correct option is a.pharynx.

The gastrointestinal system includes the organs and glands involved in the digestion and absorption of food. It includes the oesophagus, stomach, small intestines, large intestine, liver and pancreas. The food is broken down into smaller particles in the stomach.

The food is then acted upon by various enzymes to reduce them into simplest forms which facilitate their absorption.

The pharynx serves as a common passage for food and air. It is a part of the digestive system and conducting zone of the respiratory system. The human pharynx has three parts-nasopharynx, oropharynx and laryngopharynx. It is also important in vocalisation.

Anika [276]

A solid minute object that is said to come together for the formation of the planet and are believed to produce cosmic dust are called planetesimal.

The options that best describes the planetesimals are:

Option A. They are the origins of planets.

Option B. They formed from gas and dust.

Option D. They are believed to have developed in debris disks.

The descriptions can be explained as:

It is believed that planets formation occurred through planetesimals. The formation happened from gas, dust particles and debris.

By the process of accretion, the discs coalesced and became bigger and solid over time. This bigger mass started attracting other matters towards each other because of gravitational force.

This pull resulted in either breaking or creation a bigger mass of pieces known as planetesimals. The collision continued to become bigger and solid planets we know today.

Therefore, options A, B and D are correct.
