Which of these provides evidence of the common ancestry of all life?
A.Ubiquitous use of catalysts by living systems
B.Near universality of the genetic code
C.Structure of the nucleus
D.The flow of genetic information from DNA to RNA to protein
E. The directionality of protein synthesis

Answer:d

Explanation:

The organism is made of genetic material that it inherits from the parent cell. The universality of the genetic code provides evidence of the common ancestry of all life. Thus, option B is correct.

A genetic code is a triplet of nucleotides that are also defined as codons that characterizes a specific amino acid produced through the process of translation. It consists of the DNA or RNA as the base that forms the codons.

The codons have been unambiguous for a type of amino acid it codes, universal for all living organisms irrespective of the kingdom, and redundant. They are crucial evidence that supports the common originality theory of organisms.

Therefore, option B. the universality of the genetic code is evidence that supports the theory of common ancestry.

A population of rabbits lives in a grassy field that is lush and green in summer and covered in snow in winter. At the start of the summer, 75% of the population are white rabbits, and the remaining 25% of the population are brown rabbits. In rabbits, white (W) is dominant over brown (w). During the summer, the field where they live experiences a drought. The summer drought lasts for two years, through many generations of rabbits.
Which prediction BEST estimates the expected percent of white and brown rabbits in the population at the end of the drought?

A researcher in 2024 studies the evolutionary relationships between influenza viruses by comparing the genomic sequences of the viruses found in pigs, ducks, and humans in a given year.

What information supports the hypothesis that cross-species transfer leads to more severe disease in the new host

Some male birds are very colorful and stand out visually in comparison the their drab counterparts. They also may make loud
vocalizations during courtship. These visual and auditory signals may make then more likely to attract predators and be killed.
Evaluate the statements to find the best description for the evolution of male coloration and vocalization in birds.
-0,)
A)
Colorful and vocal birds may be eaten by predators with greater frequency,
so this is a poor adaptation.
B)
Colorful and vocal male birds may attract the most mates and pass on
their genes. This is an adaptive trait.
Colorful and vocal birds mimic their drab counterparts when predators are
nearby, so predators are just as likely to eat any member of the population.
O
D)
Colorful and vocal birds will only mate with colorful and vocal females,
meaning these groups will become a different species from their drab
counterparts.

Question 4 (2 points)
Move the growth rate r slider to its lowest value of 0.1, then gradually increase it. What happens to the population size as you increase the growth rate (the r slider)?



Question 4 options:

As the growth rate increases, the population size moves up and down rapidly.


As the growth rate increases, the population size stays the same.


As the growth rate increases, the population size decreases more rapidly. The slope flattens out.

Question 13 options:

The population would continue to grow at the same rate until it hit 200 and then it would grow at a slower rate until it reached 350 kudu


The population would continue to grow until it hit the new carrying capacity.


It would provide more space for the trophy hunters to move in and hunt the kudu.

Question 14 (2 points)
Reset the carrying capacity back to 200. Trophy hunters move into the area, leading to an increased death rate, which decreases the growth rate r to 0.15. How would this impact the population size? (Hint: Look at when the population reaches its carrying capacity, look at the T value)

Question 14 options:

The kudu would grow at a very slow rate for 30 years and then the growth rate would slow down.


It would take about 25 more years for the kudu to reach their carrying capacity.


The population would reach its peak in the first 10 years
