Earth’s surface is broken into large pieces that are slowly shifting. This gradual process, known as plate tectonics, accounts for movement of entire continents over time. During the past century, geologists have found multiple lines of evidence that support the theory of plate tectonics, including the mechanism that drives the plates’ motion—sea floor spreading. As a result, sections of Earth’s crust are constantly being pulled apart or pushed together. This movement creates many of Earth’s landforms, such as mountains, rift valleys, and volcanoes.
According to the theory of plate tectonics, 250 million years ago all of Earth’s landmasses were clustered into one supercontinent, known as Pangea. Based on the past and current movements of Earth’s plates, predict how the location of the continents might shift during the next 250 million years. Do you think they’ll spread out, cluster together, or move in a combination of the two? What types of landforms do you anticipate forming as a result? What effect, if any, do you anticipate this movement will have on life on Earth?
Solution 1
Explanation:
They will be combine together and form a large same land as before some thousand years ago. This will somehow destroy the then population but will start a new civilization with new innovations and ammenities.

Answer:
A. Selective pressure in the form of a new predator
Explanation:
A. Selective pressure in the form of a new predator
A. Selective pressure in the form of a new predator is the most likely factor that caused the noncroaking male population to increase after 2004.
What is noncroaking males?
Noncroaking males refer to male bullfrogs that do not produce croaking sounds as a form of communication or mating behavior.
The migration of a bat species that preyed on male frogs likely created a selective pressure on the population, favoring those males that did not croak and thereby avoiding detection by the predator. This would result in a higher proportion of noncroaking males in the population over time as they have a higher likelihood of survival and reproduction.
The increase in the noncroaking male population after the arrival of the bat predator in 2005 could be due to adaptation of the male frogs to the new selective pressure in the form of the predator.
It is possible that the noncroaking males were able to avoid detection by the bat predator better than the croaking males, leading to a higher survival rate and ultimately a higher population.
Additionally, it is possible that the croaking males were more likely to be predated upon, leading to a decrease in their population and an increase in the noncroaking male population.
However, it is also possible that other factors, such as changes in the environment or competition with other species, could have contributed to the observed changes in the bullfrog population over time.

Explanation:
Cystic Fibrosis, also called CF, is an inherited life-threatening disorder which causes immense damage to the lungs and digestive system. Cystic fibrosis changes the cells that produce mucus, sweat, and digestive juices. By changing these cells, it causes these fluids to become thick & sticky. They then plug up tubes, ducts, and passageways.

d. 260/1545
e. (500+515)/1545
f. 1545/260
g. 1545/270
From these results one can conclude that:_______.
a. the two genes are linked
b. the two genes are not linked
c. if the genes are linked, they are separated far enough apart to appear to assort independently
Answer:
1) option a is correct. (260+270)/1545
(Note about this option: In the statement, it is written as (260+270) 1545. Lacks the division symbol, / )
2) From these results one can conclude that the two genes are linked (option a)
Explanation:
To know if two genes are linked, we must observe the progeny distribution. If heterozygous individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, phenotypes appearing in different proportions, we can assume linked genes in the double heterozygote parent.
We might verify which are the recombinant gametes produced by the di-hybrid, and we will be able to recognize them by looking at the phenotypes with lower frequencies in the progeny. Phenotypes with the highest frequencies represent the parental gametes.
To calculate the recombination frequency, we will use the following formula: P = Recombinant number / Total of individuals.
In the present example:
Parental) YySs x yyss
Gametes) YS parental type ys, ys, ys, ys
ys parental type
Ys recombinant type
yS recombinante type
The total number of individuals in the offspring: 1545
Phenotypic class Number of offspring
- 500 Y-S- (parental)
- 515 yyss (parental)
- 260 Y-ss (recombinant)
- 270 yyS- (recombinant)
According to this information, the phenotypic frequencies of the progeny differ from the phenotypic ratio 1:1:1:1. We can assume then, that these genes are linked.
The recombination frequency is:
P = Recombinant number / Total of individuals
P = 260 + 270 / 1545
P = 530/1545
P = 0.343
The genetic distance between genes is 0.343 x 100= 34.4 MU.
