This is false. There are many factors, like climate, fires, pollution, etc.
Answer:
To predict the results of the offspring from a cross between brown heterozygous rabbit and a white homozygous rabbit, a punnet square can be drawn as follows:
b b
B Bb Bb
b bb bb
The results from the punnet square show that there is 2:2 ratio that the offspring will be brown coloured or white coloured. The genotype of the rabbits will either be heterozygous brown i.e Bb or homozygous white bb.
there is a 50% chance that the offspring will be brown rabbit and there is also a 50% chance that the offspring can be a white rabbit.
The spiders have became resistant to the pesticide.
Answer: absolute certainty is often difficult to achieve. Scientific uncertainty generally means that there is a range of possible values within which the true value of the measurement lies.
