Answer:

Answer the following multiple choice question by selecting the correct option.
Context: Neurogenesis At one time, scientists believed that people were born with all the neurons they would ever have. Research performed during the last few decades indicates that neurogenesis, the birth of new neurons, continues into adulthood. Neurogenesis was first discovered in songbirds that produce new neurons while learning songs. For mammals, new neurons also play an important role in learning: about 1,000 new neurons develop in the hippocampus (a brain structure involved in learning and memory) each day. While most of the new neurons will die, researchers found that an increase in the number of surviving new neurons in the hippocampus correlated with how well rats learned a new task. Interestingly, both exercise and some antidepressant medications also promote neurogenesis in the hippocampus. Stress has the opposite effect. While neurogenesis is quite limited compared to regeneration in other tissues, research in this area may lead to new treatments for disorders such as Alzheimer’s, stroke, and epilepsy. How do scientists identify new neurons? A researcher can inject a compound called bromodeoxyuridine (BrdU) into the brain of an animal. While all cells will be exposed to BrdU, BrdU will only be incorporated into the DNA of newly generated cells that are in S phase. A technique called immunohistochemistry can be used to attach a fluorescent label to the incorporated BrdU, and a researcher can use fluorescent microscopy to visualize the presence of BrdU, and thus new neurons, in brain tissue (Figure 16.20).

Answer the following multiple choice question by selecting the correct option.
Context: Plant Parasites Protist parasites of terrestrial plants include agents that destroy food crops. The oomycete Plasmopara viticola parasitizes grape plants, causing a disease called downy mildew (Figure 13.18a). Grape plants infected with P. viticola appear stunted and have discolored withered leaves. The spread of downy mildew caused the near collapse of the French wine industry in the nineteenth century.

Question: A basketball team won 40 games in their last competition. In the next competition, they won 5/8 times as many games as they won in their first competition. In the third competition, they won the same number of games as the sum of the first and second competition winnings. Calculate the total number of wins they had in the three competitions.

Answer the following multiple choice question by selecting the correct option.
Context: If they won 40 games in the first competition, they won 5/8*40 = <<5/8*40=25>>25 games in their second season.
In the third competition, they won games equal to the sum of the games they won in the last two competitions, which is 25+40 = <<25+40=65>>65 games.
Since the total number of games they won in the first two competitions is 65, and they won 65 more in the third competition, they won a total of 65+65 = <<65+65=130>>130 in all competitions.
#### 130

Answer the following multiple choice question by selecting the correct option.
Context: Jeff donated 30/100*300 = <<30/100*300=90>>90 pencils.
He remained with 300-90 = <<300-90=210>>210 pencils.
Vicki had twice as many pencils as Jeff, meaning he had 2*300 = <<2*300=600>>600 pencils.
When Vicki donated 3/4 of his pencils, he gave away 3/4*600= <<3/4*600=450>>450 pencils.
Vicki remained with 600-450=<<600-450=150>>150 pencils.

Answer the following multiple choice question by selecting the correct option.
Context: The Voyager 1 spacecraft visited Saturn in 1980. Voyager 2 followed in 1981. These probes sent back detailed pictures of Saturn, its rings, and some of its moons ( Figure below ). From the Voyager data, we learned what Saturn’s rings are made of. They are particles of water and ice with a little bit of dust. There are several gaps in the rings. These gaps were cleared out by moons within the rings. Gravity attracts dust and gas to the moon from the ring. This leaves a gap in the rings. Other gaps in the rings are caused by the competing forces of Saturn and its moons outside the rings.

Answer the following multiple choice question by selecting the correct option.
Context: The first 10 primes are: 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
So, we need to find approximate value Q of 2*3*5*7*11*13*17*19*23*29.
# of different approximations are possible. For example:
2*5=10
3*17=~50 (actually more than 50);
7*13=~100 (actually less than 100);
11*19=~200 (actually more than 200)
23*29=667
2*3*5*7*11*13*17*19=~10*50*100*200*667=10^7*667=6.67*10^9.

Answer the following multiple choice question by selecting the correct option.
Context: Explanation:
Clearly, we have :
B-3 = E ...(i)
B + 3 = D ...(ii)
A+B = D + E+10 ...(iii)
B = C + 2 ...(iv)
A+B + C + D + E= 133 ...(v)
From (i) and (ii), we have : 2 B = D + E ...(vi)
From (iii) and (vi), we have : A = B + 10 ...(vii)
Using (iv), (vi) and (vii) in (v), we get:
(B + 10) + B + (B - 2) + 2B = 133 => 5B = 125=> B = 25.

Question: The average weight of 8 persons increases by 1.5kg when a person weighting 65kg is replaced by a new person. What could be the weight of the new person?
A: 67kg
B: 77kg
C: 87kg
D: 97kg
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Explanation:
Let the average weight of 8 persons be ‘x’
years and the age of the new person be ‘y’ years
so, (8x – 65 + y) / 8 = x+1.5
so, y = 77kgs
65 + 8X1.5 = 77kgs
Answer B

A: 23years
B: 24years
C: 25years
D: 26years
Answer:
|
Answer the following multiple choice question by selecting the correct option.
Context: Explanation:
Ayush's present age = 5 years.
His mother's present age = (5 + 20) years = 25 years.
Ayush's father's present age = (25 + 5) years = 30 years.
Ayush's father's age at the time of Ayush's birth = (30 - 5) years = 25 years.
Therefore Ayush's father's age at the time of marriage = (25 - 2) years = 23 years.
Answer: A) 23 year

Answer:

Answer the following multiple choice question by selecting the correct option.
Context: When skater 2 runs into skater 1, he’s going faster than skater 1 so he has more momentum. Momentum is a property of a moving object that makes it hard to stop. It’s a product of the object’s mass and velocity. At the moment of the collision, skater 2 transfers some of his momentum to skater 1, who shoots forward when skater 2 runs into him. Whenever an action and reaction such as this occur, momentum is transferred from one object to the other. However, the combined momentum of the objects remains the same. In other words, momentum is conserved. This is the law of conservation of momentum .

Answer the following multiple choice question by selecting the correct option.
Context: Atoms cannot only gain extra electrons. They can also lose electrons. In either case, they become ions . Ions are atoms that have a positive or negative charge because they have unequal numbers of protons and electrons. If atoms lose electrons, they become positive ions, or cations. If atoms gain electrons, they become negative ions, or anions. Consider the example of fluorine (see Figure below ). A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.

Answer the following multiple choice question by selecting the correct option.
Context: First add up James' purchases that is $3 + $2 = $<<3+2=5>>5.
So, the amount of sales tax is $5 * .2 = $<<5*.2=1>>1.
Hence, James spent a total of $5 + $1 = $<<5+1=6>>6.

Answer the following multiple choice question by selecting the correct option.
Context: Earth itself acts like a gigantic gyroscope. Its angular momentum is along its axis and points at Polaris, the North Star. But Earth is slowly precessing (once in about 26,000 years) due to the torque of the Sun and the Moon on its nonspherical shape.
