There are two types of rabbits: those that strictly eat grass and those that strictly eat berries and flowers. A drought occurs
one year, and the plants have difficulty producing any extras (flowers, berries, etc.). They can only try and keep themselves green. Natural selection is against which rabbit?a. Those that strictly eat berries and flowers.b. Those that strictly eat grassc. Those that strictly eat grass and berriesd. Those that strictly eat grass and flowers
Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
In the given example of rabbits, those that strictly eat grass will even survive after drought because plants will try to keep themselves green and there will be no production of berries and flowers hence these rabbits will shift their food source to green plants and will be favored
But those rabbits those that strictly eat berries and flowers will not be able to survive because they were strictly dependent on berries and flowers for their food as a result they will be unfit and natural selection will be against those rabbits
Natural selection is the process whereby organisms adapted better to their environment which lead to survive and produce more offspring.
* *Natural selection was expounded by Charles Darwin .
Natural selection is now days believed to be the main process through which evolution occurs.
* It leads to survival of fittest and extinct the other which are not fit with environment.
*As here in the case of rabbits, those that strictly eat grass will even survive after drought.
But the rabbits that strictly eat berries and flowers will not be able to survive because they were strictly dependent on berries and flowers for their food.
There
are many ways to estimate ground squirrel numbers. The most common
and popular monitoring technique is the combination of electronically
recorded stress calls and visual counts where ground squirrels
respond physically, vocally or both. You simply count the number of
squirrels in a 100m by 100m area that respond to a hand-held
imitation ground squirrel call tool.
500-million-year-old fossil found in BC is ancient ancestor of spiders and scorpions. Palaeontologists in British Columbia have found a fossil of the oldest known ancestor of scorpions and spiders.
