Answer:
Mutation, fertilization, meiosis are different mechanisms by which changes can occur in the genome.
Explanation:
There are several process which is responsible for causing change in the genome of the species which results in the evolution of that species. Some of these processes are:
1. Mutation: In mutation, some nucleotide sequences get change and this change can occur due to frameshift, addition, deletion or any other process. This change in nucleotide can be seen in phenotype and helps in the evolution of the species.
2. Fertilization: During fertilization mixing of the genome of two individual takes place which results in producing a genetically distinct offspring which contains variation. So as the offspring is genetically different it can contain new alleles that can help the individual to survive in the changing environment.
Transfer = 10/100 of total energy.
<u>Explanation:</u>
Energy and matter is transferred from one organism to another by the process of food chain and food web. In food chain the organism of higher trophic level feeds on the organisms of lower trophic level. On feeding only 10% of the energy gets transferred to the organism of higher trophic level while the rest are being used in the metabolic processes and are produced as heat. This is called as ten percent energy transfer rule.
The mathematical representation of the transfer of energy is given as
Transfer = 10/100 of total energy.
Answer:
the Golgi apparatus
Explanation:
Golgi apparatus also called Golgi body is an organelle found he cytoplasm of most eukaryotic cells, which is responsible for storing maromulecules in membrane-bound vesicles like parcels, such as the proteins produced in the endoplasmic reticulum, and transporting them to their various specific destinations. This organelle helps the cell mainly in intracellular transport.
It can be compared to the shipping center of a company that package parcels with the right address on them, and delivering them to their various destinations where they are needed.
Answer:
Because the algea was not strong enough yet to live on its own and had to stay close a water source, where it could get water and sunlight without doing any work.
