Answer:
c. protein from RNA
Explanation:
Translation is a process that occurs in the ribosomes where tRNA is used to read the mRNA strand and translate the codons into complementary amino acids.
n a cross between two heterozygous individuals, the offspring would be expected to show a 3 : 1 ratio. For example, in Case 1, three-fourths of the individuals would have red (wild-type) eyes, and one-fourth would have sepia eyes.
If there are 44 offspring, how many are expected to have red eyes?
We expect three-fourths to have red eyes.
<span>34</span> of 44 = 33
If there are 44 offspring, how many are expected to have sepia eyes?
<span>14</span> of 44 = 11
Now you are ready to calculate chi-square.
Answer:
C. The differences between the observed and expected counts are too large to be attributed to chance.
Explanation:
The p-value of the statistic represents the chance that the observed count is based on luck or chance. When p value too high, the research can't be used since the chance that its not represent real condition are too high. Most researchers use 5% (0.05) as the cutoff of something called statistically significant. In this research, the p-value is 0.04 or 4%, so it is statistically significant.
<u>Answer</u>: predator and prey
<u>Explanation</u>:
The described graph illustrates the cycle of a predator and prey population. The population curves for predator and prey are not synchronized with each other and their amplitudes differ.
Changes in the prey population will not result in immediate or exactly identical changes in the predator population.
In the attached image, the red line represents the prey population and the blue the predator population. As it can be observed, when the prey population increases in size, the predator population size increases too.
However, this increase is not of the same size and is delayed in time. The predator population will continue to increase even though the prey population has started to decrease.
This has to do with the fact that the adult predators mated and gave birth when the food availability was still high. However, these new young individuals will not survive and reproduce due to decreasing prey. As the prey continues to decrease, more and more predators will perish.
The same cycle will then repeat over and over again.
