Answer:
Speciation occurred as species got separated by seas and oceans.
Explanation:
The breakup of Pangaea into Laurasia and Gondwanaland resulted in clade dispersal, isolation of clades, and change in the climate. It also influences patterns of diversity. Only those animals that survived the mass extinction that was able to adapt to the new climate conditions. Speciation occurred as species got separated by seas and oceans.

The breakup of Pangaea into Laurasia and Gondwanaland resulted in climate change. Only the animals that were able to adapt to the new climate conditions survived the mass extinction.
Explanation:
Scientists have studied a fruit fly, Drosophila, to better understand early embryonic development and have discovered that the cell cycle changes as embryonic development proceeds Model A represents the first 13 cell cycles after fertilization, which only includes two phases. Model B represents cell cycles 14 through 16, which are more complex and include a G2 phase.
What of the following explains the advantage of a G2 phase during embryonic development?
A Cells can undergo the cell cycle more quickly with a G2 phase.
B Cells can replicate more DNA with a G2 phase.
C Cells are checked for DNA damage before entering mitosis with a G2 phase
D Cells are able to produce two new daughter cells with a G2 phase.
Donna is writing a program for her book store that will help her monitor inventory. She has many different kinds of books (fiction, non-fiction, textbooks, cookbooks, etc.) that all require different types of data. She has noticed, however, that several pieces of data are the same no matter which type of book she is selling: title and price. She creates some procedures that report the title and price of a book that she can use with any kind of book she sells. This is an example of what computing principle?
Answer:
Abstraction.
Explanation:
This is an abstraction because Donna generalized a concept — reporting the title or price of a book — to apply to all types of books. Noticing repeated details or common features and removing them is a key element of abstraction.

1. Describe major depressive disorder and discuss at least eight of its symptoms. 2. How does major depressive disorder differ from bipolar disorder?
Answer:
1. Major depressive disorder or MDD, is described as experiencing sadness over a long period of time. Some symptoms of major depressive disorder include loss of interest, change in eating habits, suicidal thoughts, feeling sadness or guilt, constant tiredness, change in your appetite, unable to concentrate, or poor decision making.
2. The most obvious difference between major depressive disorder and bipolar disorder is that bipolar disorder comes with mania or a "high" period. The "high" period will include you feeling energized and having high self confidence, and after that period, you will go back to being depressed. With major depressive disorder, there is no good period, you experience constant feelings of sadness.

d.
When is the bug's velocity:
i. 0
> 0
<0
e.
When is the bug's acceleration:
i. 0
> 0
<0
f.
At what time does the bug pass over its starting point?
Answer:
a. The bug is moving at a constant speed of -2 m/s
b. The total distance traveled by the bug is 17 meters
c. The distance the bug end up from its starting point is 3 meters
d. i. The bugs velocity is 0 when t = 0, 5, or 10 seconds,
ii. The bugs velocity is > 0 at 5 ≤ t ≤ 10
iii. The bugs velocity is < 0 at 0 ≤ t ≤ 5
e. i. The bug's acceleration is 0 at 2 ≤ t ≤ 4
ii. The bug's acceleration is > 0 at 4 ≤ t ≤ 6 and 8 ≤ t ≤ 9
iii. The bug's acceleration is > 0 at 0 ≤ t ≤ 2 and 9 ≤ t ≤ 10
f. The time the bug passes the starting point is approximately 8.83 seconds
Explanation:
a. When 2 ≤ t ≤ 4, the bug is moving at a constant speed of -2 m/s
b. The total distance the bug traveled is given by the area under the velocity-time graph which consist of two trapezoid and a triangle and is therefore is given as follows;
The area of the first (negative) trapezoid = -2 × (2 + 5)/2 = -7
The area of the second trapezoid = 2 × (3.5 + 5)/2 = 8.5
The area of the triangle = 1/2 × 1.5 × 2 = 1.5
The sum of the magnitude of the areas = The total distance traveled by the bug = [tex]\left | -7 \right |[/tex] + 8.5 + 1.5 = 17
The total distance traveled by the bug = 17 meters
c. The distance the bug end up from its starting point is given by the sum of the displacement (total displacement) of the bug
The total displacement of the bug = -7 + 8.5 + 1.5 = 3
The distance the bug end up from its starting point = The total displacement of the bug = 3 meters
d. i. The bugs velocity is 0 when the graph crosses the time, 't', axis, which is at points for time, t = 0 seconds, t = 5 seconds, and t = 10 seconds
ii. The bugs velocity is > 0 between the times, 5 ≤ t ≤ 10
iii. The bugs velocity is < 0 between the times, 0 ≤ t ≤ 5
e. i. The bug's acceleration is 0 between the times, 2 ≤ t ≤ 4
ii. The bug's acceleration is > 0 between the times, 4 ≤ t ≤ 6 and 8 ≤ t ≤ 9
iii. The bug's acceleration is > 0 between the times, 0 ≤ t ≤ 2 and 9 ≤ t ≤ 10
f. The bug passes the starting point at the time, 8 + t, where 't', is given by the area of a trapezoid as follows;
2 = t × (2 + 2 + t)/2
∴ 4 = 4·t + t²
t² + 4·t - 4 = 0
(t + (2 + 2·√2))·(t - (2·√2 - 2))
∴ t = 2·√2 - 2
The time the bug passes the starting point = 8 + 2·√2 - 2 = 6 + 2·√2 ≈ 8.83
The time the bug passes the starting point ≈ 8.83 seconds

Use this knowledge to explain the decision to use atomic bombs on Japan. For this assignment you will write three well-developed paragraphs on the following:
What were the reasons the bomb should have been used on Japan?
What were the reasons the bomb should not have been used on Japan?
Should the atomic bomb have been used on Japan? Why or why not? Support your claim with evidence from the lesson.
Well, I'm not going to write your paragraphs for you because I wouldn't feel good about that. Too close to cheating. I will give you some of my notes though! I feel that these points are a good starting place for you to base your paragraphs on.
Reasons the bomb should have been used:
• Force them to surrender
• Ultimately save many lives by swiftly ending the war
• As a demonstration of American strength
• Holding true to the promise that if Japan didn’t surrender, they would face annihilation.
• As recompence for the bombing at Pearl Harbor.
Reasons the bomb should not have been used:
• It would kill a ton of people.
• The negative effects would be long lasting.
• The radiation alone killed as many people as the initial bombing
• Many of the lives lost would be those of innocent people. Children, women, the disabled and the elderly.
• 200,000 casualties

I believe it is Initiative vs. Guilt which deals with the important events of Exploration at the age of 3 to 6 years. Children need to begin asserting control and power over the environment. Success in this stage leads to a sense of purpose. Children who try to exert too much power experience disapproval, resulting in a sense of guilt.
An oil refinery can refine about 20 gallons of gasoline from one barrel of crude oil. If an automobile has a fuel economy of 25 miles per gallon, calculate the maximum number of miles an automobile could theoretically travel using the quantity of gasoline that could have been refined from the crude oil that escaped from the well in May of 2010.
Answer:
20(1,800,000)/25= 1,440,00
Explanation:
The maximum number of miles an automobile could theoretically travel is; 500x
How to create functions?At 20 gallons per barrel, x barrels produces 20x gallons. Thus;
G(x) = 20x
An automobile has a fuel economy of 25 miles per gallon. Thus;
M(g) = 25g
Where g is the number of gallons that will allow the automobile to drive 25 miles per gallon. Thus;
Maximum number of miles it can travel is;

A polar bear is standing at the bottom of a snow pile, waiting for her cub to slide down. If the angle of elevation from the bottom of the snow pile to the top is 46°, and the height of the snow pile is 9 ft, find the distance between the polar bear and the top of the snow pile.
Answer:
Distance between polar bear and top of pile = 12.51 ft (approx.)
Explanation:
Given:
Angle of elevation = 46°
Height of the snow pile = 9 ft
Find:
Distance between polar bear and top of pile
Computation:
Using trigonometry function
Sin 46° = Height of the snow pile / Distance between polar bear and top of pile
Sin 46° = 9 / Distance between polar bear and top of pile
Distance between polar bear and top of pile = 9 / 0.7193
Distance between polar bear and top of pile = 12.51 ft (approx.)

In the book all the pretty horses how does the death of Blevins help John Grady grow as a character?
Answer:
The main character of All the Pretty Horses, John Grady Cole certainly does not begin McCarthy's novel as a prototypical Western hero. At sixteen, his dream is to run the ranch on which he's lived his whole life. ... With no recourse, John Grady becomes a character in search of a story, a hero in search of a novel.
Refer to the passage.
"It is estimated that a total of seventy thousand private tube-wells were sunk during the 1969–1970 crop season in India, which brings about 1.4 million hectares of additional land under controlled irrigation, thereby greatly expanding the food production potential. It is estimated that at present less than half of the irrigation potential of India has been developed.
If the high-yielding dwarf wheat and rice varieties are the catalysts that have ignited the green revolution, then chemical fertilizer is the fuel that has powered its forward thrust. The responsiveness of the high-yielding varieties has greatly increased fertilizer consumption. The new varieties not only respond to much heavier dosages of fertilizer than the old ones but are also much more efficient in its use. The old tall-strawed varieties would produce only ten kilos of additional grain for each kilo of nitrogen applied, while the new varieties can produce twenty to twenty-five kilos or more of additional grain per kilo of nitrogen applied. Consumption of nitrogen fertilizer in India has increased from fifty-eight thousand metric tons of nutrients in 1950–1951 to 538 thousand and 1.2 million metric tons in 1964–1965 and 1969–1970 crop cycles, respectively; and about sixty percent of this amount was produced domestically.”
Norman Borlaug, accepting the 1970 Nobel Peace Prize for his role in reducing hunger in India and Pakistan
How is the position of farmers growing high-yield crops different from that of farmers growing traditional crops?
Farmers growing high-yield crops use less land, causing them to follow a higher-density settlement pattern.
Farmers growing high-yield crops are more likely to be self-sufficient and thus require less support from the rest of society.
Farmers growing high-yield crops require a larger amount of water and are therefore restricted to land within the irrigated zone.
Farmers growing high-yield crops require investment capital to fulfill their potential, but they can achieve profits and escape poverty.
Farmers who grow high-yield crops require investment capital in order to profit and escape poverty, distinguishing them from traditional crop-growing farmers. Thus, option D is correct.
Who is Norman Borlaug?Norman Borlaug was awarded the Nobel Peace Prize for his outstanding contribution in relieving hunger and poverty in India and Pakistan. He wrote about crop varieties with high yields.
For growing high-yield crops the money as an investment is required by the farmers as the seeds and the fertilizers are needed. Though it requires investment the profits and high that can make the farmers escape poverty.
Therefore, option D. high yield crops require investment is correct.

The angle that is formed from the foot of a polar bear foot to the top of the an igloo is 17°. If the polar bar is standing 131 feet from the base of the igloo, how tall is the igloo?
Answer:
Let AB be the igloo
C be the polar bear
According to the given information:
· ∠ABC = 90° (The igloo and the ground)
· ∠ACB = 17° (The foot of the polar bear to the top of the igloo)
· BC would be the distance between the polar bear and the igloo, BC = 131 ft
The height of the igloo is:
tan 17° = AB / BC
AB = tan 17° × BC
AB = tan 17° × 131
AB = 40.05 ft

this is the answer of your question
A plant that grows on other plants, but provides its own food, is called an epiphyte. The correct option is B.
What are epiphytes?Epiphytes, sometimes known as "air plants," are plants that coexist peacefully and safely on top of other plants (usually trees). They get their nutrients and other essentials from the nearby dust, water, air, and debris.
Most epiphytes can be hydrated by misting them or soaking the base where they are growing. Since almost all epiphytes naturally develop in warm, tropical climates, they require a warm setting.
A plant known as an epiphyte is one that develops on the surface of another plant, such as a tree. Instead of getting its water and nutrients from the tree, it takes them from the air and its surroundings. The epiphyte's presence has no impact on the tree.
Therefore, the correct option is B) epiphyte.
