Question number 2 the dna the answer is number 4 the last one
Answer:
d) Increasing the pH makes it easier for lactase to function correctly.
Explanation:
Answer:
Cell membranes are selectively permeable which means it allow certain molecules to move across it into and out of the cell. Cells need to be able to transport these substances to live and grow.
Transport of ions, water maintains the osmotic pressure of the cell. Transport of sugars like glucose is necessary to generate energy for the metabolic activities of the cell. Gases like CO2 are waste products of metabolic reaction which are removed by the cell through the cell membrane. Amino acids are required to make proteins.
Transport across cell can occur through active and passive transport and transport of these substance are necessary for a cell to live and function properly.
Parasitism
Parasitism can be defined
as a relationship between species in which one organism (parasite) lives on or
in another organism which is the host, causing it some harm without immediately
killing it. Thus, parasitism is a kinds of close, symbiosis and persistent
biological interactions.
Answer:
What will happen to the population of mice that it will keep growing at a tremendous rate without a fear of being caught by a predatory. This will increase the population curve of mice but will decrease the population curve of the cat at similar speed.
What else can happen is that cats will no longer be depending on Mice for their food and they will be finding some alternate food host.
What else can happen is the trait of tailless cannot be favored by environment as proposed by Lamarack in his theory of evolution that if organism acquires some favorable trait during his life then it is possible that he will pass this trait to offspring. Though this trait is not naturally induced therefore, there are no chances that tailless mice can born and nature choose it as a favorable trait.
In 1880 August weismenn did experiment of similar nature, he cut off the tails of 20 successive generations of mice abut not a single tailless mouse was born. Therefore, he proved that until nature selects some traits, they are not that easily passed from one generation to another if induced by human.
Conclusion: <em>Therefore, after 50 generation mice will be just like parent mice with tails however they will have good population and less predators.</em>
Hope it help!
