Question: Jezelyn needs to create a project that shows reproductive isolation in action and decides to make a video. Which of the following would make the best project?

a video that shows a large river that has penguin populations on both sides

a video that shows penguin species that have different mating dances a video that shows

a penguin that is laying eggs a video that shows penguins in a tidal pool and an open ocean

The right option is a video that shows penguin species that have different mating dances.

Explanation:

Reproductive isolation is the inability of animals of closely-related species to interbreed with one another successfully as a result of various differences which can be ecological, behavioral, psychological, or genetic. From the question given above, the difference in the mating dances of the penguin species will not allow the animals to unite and mate. This condition describes reproductive isolation. Reproductive isolation is caused by mating differences, sterility or environmental barriers that eventually lead to the adaptive splitting into two species. However, reproductive isolation is not sufficient but internal barriers to gene flow are required for speciation to evolve.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
