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.

Answer:
The correct answer will be option-B.
Explanation:
The plant tissues are composed of three types of cells: parenchyma, collenchyma and sclerenchyma.
The parenchyma and collenchyma remain alive at their maturity but sclerenchyma loses their protoplasm and become dead. These cells deposit lignin in their secondary walls and form hard tissues of the plant-like hard shell of a coconut. Sclerenchyma provides mechanical strength to the plant.
Thus, Option-B is the correct answer.
Answer;
-Sodium
Because Andy has high blood pressure and heart disease, he must lower his intake of Sodium.
Explanation;
-Eating substances rich in sodium such as salt raises the amount of sodium in the bloodstream and wrecks the delicate balance, reducing the ability of the kidneys to remove the water.The result is a higher blood pressure due to the extra fluid and extra strain on the delicate blood vessels leading to the kidneys.
-Therefore, for an individual with high blood pressure and heart disease like the case of Andy, he or she must lower the intake of sodium.
