The plant would shrivel up and die. The central vacuole holds water maintaining turgor pressure in the plant, and without the vacuole, the plant would shrivel.
Answer:
the difference between rocks and minerals .A mineral is a naturally not occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids.
Explanation:
Answer:
2. Circular, looped, folded, single stranded DNA known as the bacterial chromosome
Explanation:
The bacterial chromosome of a prokaryotic cell, does not occur in the typical X chromosome found in eukaryotic cells, but it is a long folded and looped molecule composed of double-stranded supercoiled DNA. In this case, DNA occurs freely and covalently closed in a circular shape in the cytoplasm and it does not bind with proteins.
<h2>Answer:</h2>
The pH of the pond water and survival rate of animal species living in the pond has a direct relationship with each other. Animal species can survive at a specific level of pH"Optimum pH" at which these species can show their maximum activity.
If we decrease the pH the pond water will become more acidic and it will become challenging for species to survive in the acidic environment and if we increase the pH the water becomes more alkaline and again it affects the marine life. So, the pH of pond water should be in normal ranges.
Explanation:
Bohr model is able to explain the electromagnetic spectrum produced by different atoms of different elements. This is because an electron around the nucleus of an atom occupies distinct orbital levels around the nucleus and not in between. When an electron absorbs a specific wavelength of electromagnetic spectrum it 'hops' to an upper electron energy level equivalent to this wavelength of radiation. When the atom 'hops' to a lower orbital level it releases ta specific wavelength of radiation that is equivalent to the difference in the energy levels. This was unaccounted for in the Rutherford's planetary model.
The electron cloud model is thought to be an improvement on the Bohr model because it accounts for the Heisenberg Uncertainty Principle which stipulates that it is impossible to ascertain the momentum and location of an electron at the same time (because merely viewing an electron using light -or any kind of radiation - will change its direction and velocity). This model explains the likely position of an electron using probabilistic equations. The electron cloud model can therefore be used to explain bonding between atoms.
