Answer:
Bb and Bb
Explanation:
This is the only combination of the four that will produce both mice with black fur and mice with white fur. Option A will only give black fur, option B will only give white fur, and option C will only give black fur since parent 1 will only give the dominant B allele to the offspring. With Bb and Bb, the genotypes of the resulting offspring could be BB, Bb (which will result in black fur) or bb (which will result in white fur).
Answer:
These are some of the disadvantages of sexual reproduction: time and energy are needed to find a mate.
hope this helps!
This process is called passive transport or facilitated diffusion, and does not require energy. The solute can move ''uphill'', from regions of lower to higher concentration. This process is also called active transport, and requires some form of chemical energy.

Answer:
Organisms better adapted to the environment
Explanation:
According to the evolutionary theory proposed by Charles Darwin in "The Origin of Species" (1859), the fittest organisms are those that are better suited to the environment (i.e., have a higher fitness). These organisms have more chances to survive and reproduce, and thereby they have also more chances to leave their genes in the next generation. This process is the central concept of evolution, and it is called natural selection. In consequence, evolution produces phenotypic changes or 'adaptations' that are inherited by organisms over generations, and certain traits are lost during this process.
