A cell is placed in a water solution with the same salt concentration as the cell. The cell is placed in a _____.

Answers

Answer 1

Answer:

The right answer is an isotonic solution.

An isotonic solution is a system in which the osmotic concentration is the same as the solute concentration of a cell. In this case, the cell does not swell or shrink because there is no gradient of water concentration across the cell membrane.

The water molecules diffuse across the plasma membrane in both directions, and the rate of water diffusion is the same in each direction of this cell without gaining or losing water.

Answer 2

Answer: Isotonic solution. Since it has the same salt concentration as the cell the solution is neither hypotonic or hypertonic.

B) varied diet and prolific reproduction

C) prolific reproduction and strong hind legs

D) strong hind legs and venom glands

Answers

The right option is A) venom glands and varied diet

The venom glands and varied diet are most responsible for the success of the cane toad as an invasive species in Australia.

The cane toad is a big terrestrial toad usually used as pest control against the cane beetle. The cane toads have a toxic skin and venom glands behind their eyes that secrete toxins.

B) The Euglena cells die because they are completely autotrophic in nature and are unable to create food in the absence of sunlight. C) The Euglena cells, which are both autotrophic and heterotrophic, remain alive even in the absence of sunlight because they

Answers

The conclusion of this experiment would be the Euglena cells, which are both autotrophic and heterotrophic remain alive even in the absence of sunlight because they are able to feed on the organic materials that are present in the pond water. The correct option among all the options that are given in the question is the third option or option "C".

The phenomenon of fusion is likely to occur when, after a period of geographic isolation, two populations meet?their chromosomes are no longer homologous enough to permit meiosis. the hybrid zone is inhospitable to hybrid survival. an increasing number of viable, fertile hybrids is produced over the course of generations a constant number of viable, fertile hybrids is produced over the course of generations. a decreasing number of viable, fertile hybrids is produced over the course of generations.

Answers

The right answer for the question that is being asked and shown above is that: "a decreasing number of viable, fertile hybrids is produced over the course of generations." The phenomenon of fusion is likely to occur when, after a period of geographic isolation, two populations meet is that a decreasing number of viable, fertile hybrids is produced over the course of generations.
