The right answer is A) Uses H2S for an energy source.
Beggiatoa is a bacterium that lives in sulphide-rich environments. They use H2S as a source of energy.
Purple sulfur bacteria, are also bacteria that depend on the presence of H2S but do not use it for the purpose of producing energy. They use it as the ultimate electron acceptor in its respiratory chain (instead of oxygen), since they are anaerobic bacteria.
Answer: Transfer RNA delivers specific amino acids to the ribosome, matching messenger RNA codons.
Explanation:
b. multicellular
c. motile
d. heterotrophs
Answer:
a. Eukaryotes, and b. multicellular.
Explanation:
Eukaryotic organisms are those organisms that have cells with membrane bound organells, such as nucleus, mitochondria, and glogi body.
Both plants and animals are multicellular (made up of more than one cell) eukaryotic organisms that belong to domain Eukarya.
However, plants are phototrophic organisms that make their own food, while animals are heterotropic that depend on other organisms for food. An another difference between plants and animals is motility as plants are generally non-motile, while animals are motile.
Thus, options (a) and (b) are the correct answers.
In agriculture, fertilizers are commonly used. But when they reach the bay, they could be cause of escessive nutrients. Algae use the presence of increased nutrients and enhance their own growth. It is known that they produce an oxygen in the photosynthesis, so it is not a problem while they are still alive. But when these organisms die, their decomposition begins. For the process of decomposition, the oxygen is needed and ultimately it will be depleted from a body of water. This will lead to the death of aquatic animals that depend on oxygen.
Answer:
Hypotonic solution.
Explanation:
Hypotonic solution is defined as a solution which has lower solute concentration with comparison to another solution of a cell.
The plant cell is takes up water from the outside of the cell where high water concentration is present so water is moves in of the cell with the help of osmosis process and start to become swell, but with the help cell wall which is present on cell prevents it from bursting when the plant cell is present in this solution (hypotonic solution).
So, if the plant cell is placed in a hypotonic solution it to become firmer and more rigid.
Answer:
A hypotonic solution
