Ans. Yeast, Penicillium, Aspergillus.
Fungi that produce medically significant compounds are considered as medicinal fungi, such as Penecillium. These medically significant compounds include anti-cancer drugs, antibiotics, cholesterol inhibitors, hormone analogs, and immunosupressents.
Various yeast strains are used to synthesize recombinant insulin (insulin analog).Penicillium provides antibiotic penicillin that kills various gram-positive bacteria. Aspergillus is used in medicine as it provides cholesterol inhibitors, such as statins.
Thus, options). 'yeast', 'penicillium', and 'aspergillus' are correct.
Gametes
Spores
Gametophyte
sporophyte i just got it correct on my quiz
b) a place on the ocean floor where a volcano is gradually forming
c) a place where water heated by magma rises from the ocean floor
d) a crack through which magma reaches the ocean floor creating new crust
Answer:
Option (C)
Explanation:
The hydrothermal vents are the narrow cracks or passage at the ocean floor through which the hot water comes out.The water when percolates beneath the ocean floor through the cracks, then it gets heated up reacting with the hot molten magma and again comes out through those narrow openings. These narrow openings through which the liquid or a gas is allowed to pass is known as the hydrothermal vents.
They are commonly found near the volcanoes and the mid oceanic ridge. It plays an important role in controlling the ocean water chemistry.
Hence, the correct answer is option (C).
b. They burst as one to move from outside to inside the cells as a result of osmosis
c. No change occurs as water freely diffuses back-and-forth across the cells membrane
d. DeSales expand energy pumping water out in response to the great external salt concentration
Answer:
The correct answer would be a. They shrink as water moves from inside to outside the cells as a result of osmosis.
Osmosis refers to the movement of water from the region of high solvent or water concentration to the region of low solvent or water concentration.
In this condition, the concentration of water in a concentrated salt (hypertonic) solution would be less as compared to that of a red blood cell.
Thus, the water from inside the cell will move outside the cell. Consequently, the cell would shrink in size.
If we place human red blood cells in a concentrated salt solution, then they shrink as water moves from inside to outside the cells as a result of osmosis.
Further Explanation:
Osmosis refers to the spontaneous movement of the solvent particles via a semi-permeable membrane from a lower to the higher region of concentration, in the direction which tends to maintain equilibrium onto both sides.
For a cell to survive, the ion concentrations outside and inside the cell should be the same. Also, the water concentration is limited because a higher concentration of water can burst and swell the cell. Osmosis is crucial in the biological systems as the membranes are semi-permeable. Also, focus on maintaining the equilibrium on both sides and prevent the bursting of the cell. If a blood cell is placed in a beaker that is filled with the concentrated salt solution then the solvent present in the cell moves outside to the cell to maintain the homeostasis of the cell this phenomenon is mainly known as exo-osmosis.
