Answer:
Eventually, as stars age, they evolve away from the main sequence to become red giants or supergiants. The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.

Answer:
The organisms reproduce in two ways:
Asexual Reproduction– In this process, only a single parent is involved and no gamete formation takes place.
Sexual Reproduction– In this process, two parents are involved and gamete formation takes place. Meiosis is an important step in sexual reproduction.
Key Points on How do organisms reproduce
- Reproduction is the process of producing new individuals of the same kind.
- Organisms reproduce in two ways- asexually and sexually.
- Asexual reproduction does not involve the fusion of male and female gametes. This takes place in bacteria, amoeba, hydra, etc.
- Sexual reproduction involves the fusion of male and female gametes and can be seen in humans and many animals.
- Fission, budding, vegetative propagation, fragmentation are some different types of asexual reproduction. It does not require any reproductive organs.
- Sexual reproduction involves the reproductive organs of male and female.
