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.
Answer:
the population starts to slowly decline
Explanation:
The population will decline drastically because there is not enough resources to sustain the population or increase the population.
Mutations are sudden spontaneous random changes that occur in the genetic make up of an organisms. A substitution mutation is a type of mutation that exchanges one base for another, for example a change in a single base such as switching an A to a G). Substitution could cause a change of codon to one that encodes a different amino acid and cause a small change in the protein produced. In the above sequence AAT-CCG-GTG in substitution of a single base
Scientists predict that banning the use of chlorofluorocarbons will gradually restore the ozone layer.
this would be Prokaryotes because bacteria are single celled organisms
