Answer:

After DNA replication, each chromosome now consists of two physically attached sister chromatids. After chromosome condensation, the chromosomes condense to form compact structures (still made up of two chromatids). ... The two copies of a chromosome are called sister chromatids

In 1859, a small colony of 24 rabbits was brought to Australia. By 1928 it was estimated that there were 500 million rabbits in
Tpy6a [65]

The rabbits had no natural predators  in Australia.

Explanation:

  • 'The rabbits were affected by many limiting factors.' This could not be a possibility because the limiting factors have a negative impact on growth rate of population. The limiting factors hinder the growth of population so if there were too many limiting factors affecting the rabbit, then the growth in population was not possible.
  • The rabbits reproduced by asexual reproduction. Rabbits are mammals and it is a known fact that they reproduce sexually. Thus this option is not possible.
  • The rabbits were unable to adapt to the environment If the rabbits were not adapted to the environment then they must not have survived efficiently in Australia. Hence, this is not a possibility.
  • Thus, the only possibility that remains is that , The rabbits had no natural predators in Australia' Otherwise, the predators would have preyed upon the Rabbits and there population must not have increased in this rate.

Diffusing molecules move ________ until they are ________. Through channels of active transport proteins; evenly distributed up
koban [17]

Answer;

-Down the concentration gradients; evenly distributed

Diffusing molecules move down the concentration gradients until they are evenly distributed.

Explanation;

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.

-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.
