True or false? A mating between a tetraploid individual and a diploid individual produces biologically fit offspring.
Katyanochek1 [597]

A cross between a diploid individual and a tetraploid individual produces triploid offspring.  There are many species of plants that are triploid, but those come from crosses between two triploid individuals. In those cases, the chromosomes from one parent match up with the chromosomes from the other parent just fine. The same is not true with a cross of a tetraploid and a diploid.  In that case, one third of the chromosomes are unmatch, causing many offspring to die, to be sterile, or to be generally unfit.  Long story short, the answer you seek is False.

A major disturbance that the ecosystem was able to recover completely from. ____________________________________________________
icang [17]

Complete Question:

I made the grass diseased. This caused all of the populations above it (rabbit, snake, and hawk) to rapidly decrease over the 12 month period

(a) A major disturbance that the ecosystem was able to recover completely from __________

(b) A major disturbance that caused the ecosystem to stabilize at a new equilibrium ____________

(c) A major disturbance that caused the ecosystem to completely collapse __________

ANSWER:

(a) reducing the hawks to nearly zero

(b) removing all of the hawks

(c) removing all the diseased.

Explanation:

(a) reducing the hawks to nearly zero will cause low depletion of the producer (plants) and this will allow the plant to grow (without visible depletion) over a period of time.

(b) for the ecosystem to stabilize at a new equilibrium, the tertiary consumer (hawks) will be totally removed from the ecosystem. Since there's no tertiary consumer to checkmate the density of other components of the food chain, it will make it form a balanced ecosystem.

(c) for ecosystem to collapse, it's important to note that the removal of the producer (plants) will be bring about the loss of the ecosystem. Since, their is no manufacturer of food, the primary consumer (rabbit) in the food chain will be starved and overtime the rabbits will be wiped out and this will caused the loss of secondary and tertiary consumer in the long run.
