A star is formed within the clouds of dust. These clouds of dust are scattered throughout the galaxy. These dust clouds are called as nebula. The turbulence inside the dust clouds rise to form knots. These knots along with sufficient mass causes gas and dust to collapse with the help of gravitational force. These sequence of steps leads to form a star.

The fact that monotremes, such as the platypus, lay eggs "indicates that they are more closely related to reptiles than to other mammals".
<u>Option: D</u>
<u>Explanation:</u>
The explanation that unusual, egg-laying mammals still exist today might be because of their descendants have taken to the water. The oviparous mammals, the word itself suggest something unique — the monotremes, such as the platypus, understood as eccentric relatives of the majority of the mammals that carry young living.
Other traits, apart from laying eggs, make them look more like reptiles than our family. They have a reptilian gait with legs on the sides instead of under the body, and a single opening for urine, feces and sex instead of multiple outlets.
Answer: Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.
Explanation:
1. Structural proteins, maintain cell shape, akin to a skeleton, and compose structural parts of the body, like cartilage and bone in vertebrates.
2. Storage proteins house critical elements that your body needs.
3. Hormonal proteins basically act as your body's chemical "messengers."
4. Enzymes, which are biological catalysts needed for chemical reactions.
