Why is a freshwater aquarium dangerous habitat for saltwater fish?
A fish that lives in salt water will have somewhat salty water inside itself. Put it in the freshwater, and the freshwater will, through osmosis, enter the fish, causing its cells to swell, and the fish will die.
Which of the following is the reason why plants wilt if they are watered with a salt solution?
If you water a plant with salt water, it will wilt, and will eventually die. This is due to the fact that the salt water is a hypertonic solution when compared to the plant cells, and water inside the plant cells will diffuse by osmosis out of the cells in order to reduce the concentration of the salt solution.
Which of these is a characteristic of body cells that require large amounts of energy quizlet?
Which of these is a characteristic of body cells that require large amounts of energy? They have a large number of mitochondria. Which group of organelles is directly responsible for the production of new molecules within a cell?
Which of these best explains why energy is needed for active transport quizlet?
Active transport requires energy as it is working against a concentration gradient and needs energy to rotate the protein transporting the solute. The energy is produced in respiration and comes from the mitochondria. The higher the rte of respiration, the higher the rate of active transport.
Why would it be dangerous for a saltwater fish to be in freshwater quizlet?
Fresh water does not have enough salt concentration to satisfy the survival of saltwater fish. Therefore the fish’s hypertonic cells will become hypotonic which will not mix well with the body structure of salt water fish, and they will die.
What will happen to the freshwater fish if you place it in sea water and why quizlet?
What will happen to the freshwater fish if you place it in sea water and why? Eventually, the freshwater fish will die. Water will leave its cells causing crenation. sodium ions out of the cell and potassium ions into the cell.
Why do plants wilt quizlet?
What is the usual cause of a plant wilting? Lack of water to a plant will decrease turgor pressure within the plant cells thus resulting in wilting. Thus, water moves passively into the root cells by osmosis.
Why do plants wilt?
On a hot, dry day (or after several days with no rain or watering), transpiration causes more water to be lost than is coming in, and the water balance within the plant can get thrown off. The dehydrated collapsing cells in the leaves and stems can no longer remain erect, and the plant begins to wilt.
Which of these characteristics of body cells that require large amounts of energy?
Mitochondria are found in the cells of nearly every eukaryotic organism, including plants and animals. Cells that require a lot of energy, such as muscle cells, can contain hundreds or thousands of mitochondria.
Why is water so important to cells?
Water is an essential constituent of the protoplasm of living cells because it is directly involved in countless biochemical reactions like photosynthesis and respiration. Without it cells couldn’t move waste and by-products, take in nutrients, perform intracelluar transportation, functioning and signalling.
What best explains why energy is needed for active transport?
Active transport requires energy because it is not a passive process. The molecule has to go against the concentration gradient. Hence it requires energy to be carried by the carrier proteins.
Which of these explains why energy is needed for active transport?
This process is a form of active transport that moves three sodium ions to the outside of a cell for every two potassium ions that it moves into the cell. Which of these best explains why energy is needed for active transport? The energy in the bonds of glucose molecules is transferred to the phosphate bonds in ATP.
How do freshwater and saltwater fish survive in their corresponding waters?
How freshwater and saltwater fish survive in their corresponding waters. Seawater is hypertonic to the fish living in it, which means that the salt content of the surrounding water is higher than the content inside the fish. As a result, they lose the water inside their body to the surrounding seawater due to osmosis.
Why do saltwater fish die in freshwater?
Saltwater fish have a different body chemistry than their freshwater counterparts. Their bodies have hypertonic cells, which keep more salt inside the cells (than outside of them). Therefore, putting them in freshwater will make the water rush into their cells and and eventually kill them.
How do Fish absorb and excrete water?
Fish osmoregulate through their gills, kidneys and intestines. Fish that live in salty marine waters absorb most of the water they take in and expend energy to excrete the excess salt through their kidneys and gills. Freshwater fish excrete large amounts of water and retain most of the ions, as well as urea.
Why is fresh water hypotonic to fish?
On the other hand, fresh water is hypotonic to the fish that live in it, i.e., the salt content in their body is higher than the salt content of the water surrounding them. Due to osmosis, therefore, water continuously flows into their body (i.e., the area of high solute concentration, salt being the solute, in this case).
