I believe the answer is B. They were no longer able to acquire the necessary characteristics for survival in a changing environment. I think it is B. because trilobites mostly went extinct because of the event that wiped out 95% of Earth's species. So they didn't have the characteristics to survive. Hope I helped!
You have already worked out that the white flower must have genotype pp (two recessive white alleles) and that the purple flower could be homozygous (PP) or heterozygous (Pp).
<span>Now you need to draw Punnet squares for both possibilities and show that the way to determine the genotype is the proportion of purple offspring. If the genotype is PP, then all the progeny will inherit one P and one p, making 100% purple flowers. If the purple flower is Pp, then half will inherit P and half will inherit p, making for half white and half purple flowers in the next generation.</span>
Answer:
The organism that can live deep beneath the earth surface despite intense pressure heat lack of water and sunlight might be Nematodes.
Explanation:
- Nematodes are able to cope extreme heat or extreme cold and dehydration. They have adopted by learning technique that allows them to survive. They can transform into a hardy form called the dauer stage.
- They can survive harsh conditions for longer durations at this stage. And again awaken themselves when conditions are favourable again.
- They can be found in hot springs, deserts, high up mountains and in the deepest oceans.
Define
n = number of seeds planted.
k = number of seeds that successfully become plants.
The probability of making a profit is
p =50% = 0.5
Therefore the probability of not makng a profit is
q = 1 - p = 0.5
According to the binomial distribution, the probability of k successes out of n trials is

Create a table as shown below by using the graphing calculator.
n k P(k of n)
---- ----- ------------
4 2 0.375
8 4 0.273
10 5 0.246
12 6 0.226
16 8 0.196
20 10 0.176
50 25 0.0.112
100 50 0.08
A graph of this table shows that the probability of success i below 0.5 (50%) for all practical values of n (the number of seeds planted).
