Genetics have determined that the majority of individuals in an isolated island population have blood type B. Type A blood is found to be more common in the mainland population from which the island was settled. How could a geneticist best explain the dominance of blood type B in the island population?
Answer:
Genetic drift reduced the frequency of type A allele
Explanation:
Genetic drift can be defined as random fluctuations in the number and frequency of different gene variants (i.e., alleles) in a population due to random sampling. Genetic drift may be caused by founder effects when a small number of individuals becomes isolated from a larger population, thereby leading to the loss of genetic variation. In consequence, genetic drift is predicted to be strong on an isolated island population because the genetic pool of individuals living on the island is generally smaller in diversity compared to the original population due to random chance. In this case, it is expected that genetic drift reduces the frequency of type A individuals.

Which statement best predicts why a cell's progression through the cell cycle might be halted by the G1/S checkpoint?
Answer:
The missing options are:
A. Spindle fibers have not correctly attached to chromosomes.
B. Damage occurred to DNA when it was being copied in G1.
C. There are not enough nucleotides available to construct new DNA.
D. Proteins necessary for M phase of the cell cycle have not been produced.
The correct option is C.There are not enough nucleotides available to construct new DNA.
Explanation:
During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.

" Imagine that you are studying a population of butterflies which have 2 alleles for wing color: Blue (B) which is completely dominant over orange (b). They are in frequencies p= 0.9 and q= 0.1. What is the frequency of genotypes produced in this population, assuming HWE? "
Answer:
BB = 81%, bb = 1%, Bb = 18%
Explanation:
p + q = 1
p^2 + 2pq + q^2 = 1
p is dominant and q is recessive so p = B and q = b
0.9^2 + 2(0.9 * 0.1) + 0.1^2 = 1
BB = p^2 = 0.9^2 =0.81
bb = q^2 = 0.1^2 = 0.01
Bb = 2pq = 2*0.9*0.1 = 0.18

Which describes Aristotle's and Ptolemy's models of the solar system? Select the two correct answers.
A. Sun at center
B. geocentric
C. circular motions of planets
D. elliptical motions of planets
Answer: B. geocentric and
C. circular motions of planets
Explanation:
Aristotle's model: He thought that earth was center universe. And this universe made up only four elements.
Ptolemy's model: He thought that earth was center of universe and all celestial objects including sun, planets and moon were orbiting the around the earth. And earth did not move at all.
Aristotle's and Ptolemy's models of the solar system suggest the geocentric and circular motions of planets.
Ptolemy model of the solar system was a geocentric model. Ptolemy thought that the universe was a set of nested spheres surrounding the Earth.
Aristotle's model shows the planets moving around the Earth in an orderly manner, in uniform circular motion, neither speeding up nor slowing down.

7. In an abandoned field, the gradual replacement of grasses by shrubs and then by trees is known as A) predation B) saprophytism C) ecological succession D) transfer of energy
Answer:
C. Ecological Succession.
Explanation:
A is incorrect because predation is the act of an animal preying on another animal for food which has nothing to do with grass and trees. B is incorrect because saprophytism is the ability of certain plants to live in dead or decaying organic matter. For example, imagine mushrooms growing on decaying trees. That still doesn't explain what the REPLACEMENT of grasses, bushes, and trees are called. D is incorrect because that is energy transferring to another, that answer wouldn't make sense. From what I know, ecological succession is the process of change in the species structure of an ecological community over time. So, if there is an abandoned field but grasses and trees are slowly popping up there over time (There's a lot more to it) then C, ecological succession is your answer.

Two samples of radioactive material from the same rock is prepared for testing. Sample A is cut into a 2 inch cube. Sample B is crushed into a fine powder. Compared to the half-life of the material in Sample A, the half-life of the material in the powdered Sample B is:
Answer:
The same
Explanation:
Half life is the time taken for the number of atoms in a radioactive sample to decrease to half of the initial number of atoms. It is also the time taken for the activity of a radioactive sample to decrease to half of its original value.
If samples A and B were obtained from the same rock, then they contain the same number of atoms having the same initial activity even though the samples were not prepared in the same way for analysis.
Hence, samples A and B have the same half life.

HELP QUICK . Come up with an explanation as to why there is some advantage to a dark mouse in a lighter habitat
but not lighter mice in darker environments ?
The darker mouse could hide in the shadows easier where hunters won't look and a lighter mouse in. darker habitat would stand out more than anything around it and result in it being easy prey.
I hope this helps ^^
The advantage to a dark mouse in a lighter habitat but not lighter mice in darker environments is predators could more easily spot the dark mice on light sand.
What are the characteristics of predators?Predators are organisms that hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey. Predators can be carnivores and omnivores.
There are four commonly recognized types of predation: (1) carnivory, (2) herbivory, (3) parasitism, and (4) mutualism. Each type of predation can by categorized based on whether or not it results in the death of the prey.
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants.

To manage the grizzly bear population better, the government of Alberta introduced a hunting lottery that awards a limited number of grizzly bear hunting licenses. Predict the year that this regulation was introduced.
Answer:
The correct answer is - 1990.
Explanation:
From the graph and year - population size table it is clearly understood that the population of grizzly bear is reduced by 39 number from year 1988 to 1989.
But after 1989 from 1990 onwards population of grizzly bear is consistently rising.
Now, let us analyse the data given in question number 2 .
No. of grizzly bear deaths in Alberta from 1976 to 1988 = 581
No. of grizzly bear deaths in Alberta from 1988 to 2000 = 281
From the above data we can clearly say now that the grizzly bear population deaths starts increasing from 1990.
So, the prediction made in question no. 1 that " the government of Alberta introduced the hunting lottery award in 1990 because in 1989 it decreases and then it starts to go up again in 1990",
