Answer:
Salt triggers osmosis by attracting the water and causing it to move toward it, across the membrane. Salt is a solute. When you add water to a solute, it diffuses, spreading out the concentration of salt, creating a solution. If the concentration of salt inside a cell is the same as the concentration of salt outside the cell, the water level will stay the same, creating an isotonic solution. Cells will not gain or lose water if placed in an isotonic solution. The raisin would swell. (please mark brainliest)
Explanation:
Answer:
The correct answer will be option D (they are complementary).
Explanation:
Complementary DNA or cDNA is an edited DNA molecule synthesized from a single-stranded RNA called mRNA. The reaction of cDNA formation from mRNA is catalyzed by an enzyme called "reverse transcriptase".
The cDNA strands formed is also known as a complementary copy of mRNA as it contains no introns or non-coding sequence in its sequence similar to mRNA. cDNA is used in recombinant DNA technology to clone eukaryotic genes in prokaryotes.
Thus, option D (they are complementary) is the correct answer.
Answer:
the insects will probably die because their habitat will be taken over but the birds will thrive because there is more food. they may even overpopulate.
That would be B.
One strand will be newly made the other will be old/parent strand.
Answer:
This question lacks options, options are:
A.Carrying capacity will increase B.Carrying capacity will decrease C.Carrying capacity will remain unchanged. The correct answer is B.
Explanation:
Ecologists define 'carrying capacity' as the population of a certain species that a defined habitat can support indefinitely, without permanently damaging the ecosystem on which they are dependent,that is, the ecological carrying capacity of an ecosystem is the maximum growth limit of a biological population that the environment can support in a given period, without negative effects on that population or on the environment.
