Answer:
The correct answer is - contractile vacuoles: osmoregulation by contraction and expansion,
other vacuoles: storage of nutrients, water, and waste also help in maintaining shape.
Explanation:
Contractile vacuoles are the characteristic features of the protozoan, unicellular algae that helps in expelling water by the process of osmoregulation by expansion and contraction.
Other vacuoles are primarily the storage unit of the cell as they store excess nutrition, waste or water in it. It also helps in maintaining the shape of the cells.
Thus, the correct answer is - contractile vacuoles: osmoregulation by contraction and expansion,
other vacuoles: storage of nutrients, water, and waste also help in maintaining shape.
Ecotones contain a greater diversity of species than either of the two separate ecosystems because they contain animal and plant species from both adjacent ecosystems. For e.g. the mangrove forests represent an ecotone between marine and terrestrial ecosystems.
An ecosystem is a geographic place in which plant life, animals, and different organisms, as well as climate and landscapes, work collectively to shape a bubble of life. four - 12+ Biology, Earth science, Ecology, Geography, Human Geography, Meteorology, Physical Geography.
Ecosystems are the inspiration of the 'Biosphere' and hold the natural stability of the earth. for instance, permit's take the connection between sheep and lion inside the atmosphere; for its survival, the lion eats the sheep. And every dating like this has an effect on other creatures and flora residing within the equal vicinity.

Answer:
DNA is divided into codons which are 3 bases long. Each codon codes for a specific amino acid or signals transcription to stop or start. Inserting or deleting one base pair changes how the DNA is read, so it will often alter the amino acids the DNA sequence produces. As a result, the protein made from the gene may not function properly.
Example:
AAT CGC CGA TGA
Delete the T from the first codon
AAC GCC GAT GA
The entire sequence is read differently ^
