Assume that a 100 base pair DNA ladder contains 45 cytosines. How many guanines are there?
Answer:
45 guanines
Explanation:
In a DNA strand, each nitrogen base only pairs with one other specific base.
Adenine pairs with thymine, and cytosine pairs with guanine.
This means that the amount of adenine is always equal to the amount of thymine, and the amount of cytosine is always equal to the amount of guanine.
So, if the DNA ladder has 45 cytosines, there will be 45 guanines.
Your friend says she does not need a flu shot this year because she got one last year. How do you respond?
A. You are incorrect because the flu virus grows and develops fast enough that your resistance to previous strains may not protect you against more recent strains.”
B. You are incorrect because the flu virus mutates fast enough that your resistance to previous strains may not protect you against more recent strains.”
C. “You are correct because viruses do not grow and develop, so there is only one strain of the flu virus.”
D. You are correct because viruses do not mutate, so there is only one strain of the flu virus.
Answer:
B
Explanation:
The answer to this question is B, because even if she got the shot last year, the flu virus grows and mutates fast enough that she may not be resistant to any new strains.
B. You are incorrect because the flu virus mutates fast enough that your resistance to previous strains may not protect you against more recent strains.
Flu ShotInfluenza vaccines, usually known as flu jabs or flu shots, are antiviral vaccines that protect against influenza virus infection. As the influenza virus evolves rapidly, new vaccine versions are generated twice a year.The flu vaccination trains your body to detect an antigen (protein) on the surface of the virus by using a deactivated or weakened version of the virus.B. It' s not correct to say that one does not need a flu shot this year because she got one last year as the flu virus mutates fast enough that the resistance to previous strains may not protect her against more recent strains.For more information:

Why are there craters on the surface of the moon?(1 point)
Craters formed when acidic water dissolved the surface of the moon.
Craters developed from deep waterspouts in oceans on the moon.
Craters were created when sinkholes formed after rainstorms on the moon.
Craters resulted when meteoroids crashed into the surface of the moon.
Answer:
Craters resulted when meteoroids crashed into the surface of the moon.
Explanation:
Craters resulted when meteoroids crashed into the surface of the moon. The correct option is D.
What are carters?On many solid planets and moons, craters are the most common surface features.
Craters cover both Mercury and the Moon. Numerous circular holes cover this area of the Moon. Each of these craters was formed when an asteroid or comet collided with the Moon's surface.
A crater is a bowl-shaped depression or hollowed-out area caused by a meteorite impact, volcanic activity, or an explosion. Impact craters are craters formed by a meteorite colliding with the Earth.
Scientists can study a planet's history using impact craters even when the records are buried beneath the surface.
Buried material is ejected during impact, while outward pressure pushes the rock at the crater's edge upward, forming a rim.
Thus, the correct option is D.

Which of the following is a result of two continental crusts buckling and cracking? *
The result of two continental crusts buckling and cracking is San Andres Fault.
The San Andrés fault is a geological fault that is about 1,300 km long. This fault is located in the western part of the United States, specifically in the state of California, and reaches a part of Mexico.
The San Andrés fault arose as a result of the tectonic encounter between the North American Plate and the Pacific plate and their relative horizontal displacement.
A characteristic aspect of this fault is the great crack and buckle that is produced through a long territory. In addition, the earthquakes of 1857, 1906, 1989, 1940, among others.
According to the above, the correct answer is option D because it mentions the correct geological event, while the other options mention phenomena that are not related to the meeting of two continental plates.
