The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.

Asha walks 15 m west, then 20 m north, then 15 m east. Calculate the distance and displacement
covered by Asha.(a) (Numbering problem)_
Answer:
Asha traveled a distance of 50 m
The displacement is 20 m north.
Explanation:
Distance and Displacement
A moving object constantly travels for some distances at defined periods of time. The total moved distance is the sum of each individual distance the object traveled. It can be written as:
dtotal=d1+d2+d3+...+dn
This sum is obtained independently of the direction the object moves.
The displacement only takes into consideration the initial and final positions of the object while moving. The displacement, unlike distance, is a vectorial magnitude and can even have magnitude zero if the object starts and ends the movement at the same point.
Asha walks 15 m west, 20 m north, and 15 m east. The total distance is
dt=15 m + 20 m + 15 m = 50 m
Asha traveled a distance of 50 m
Note the final position is 20 m above the initial position since she goes 15 m west and 15 m east. Thus the displacement is 20 m north.

A parallel circuit is shown in the diagram above. In this case the current supplied by the battery splits up, and the amount going through each resistor depends on the resistance. If the values of the three resistors are: R1 = 82, R2=82, and R3 = 42, the total resistance is found by: 1/R = 1/8+1/8+ 1/4 = 1/2. This gives R = 22. With a 10 V battery, by V = 1 R the total current in the circuit is: I = V/R = 10/2 = 5 A. The individual currents can also be found using I = V/R. The voltage across each resistor is 10 V, so the resistance across R1 : 2.5A 1.25V 2.5V 1.25A

Cannon ball of mass 3.5kg is fired at a speed of 22m/s2
Answer:
77N
Explanation:
Since we are not told what to find, we can as well look for the net force acting on the ball.
According Newton's second law;
F = mass × acceleration
Given
Mass = 3.5kg
Acceleration = 22m/s²
Net force F = 3.5×22
F = 35/10×22
F = 7/2×22
F = 7×11
F =77N
Hence the magnitude of force required is 77N
Birdman is flying horizontally at a
speed of 40 m/s and a height of 58
m. Birdman releases a turd directly
above the start of the field. How far
from the start of the field should the
robot hold the bucket to catch the
turd?
Answer:
The robot should hold the bucket at 137.6 m from the start of the field
Explanation:
Horizontal Motion
When an object is launched horizontally with a speed v from a height h, it describes a curved path exclusively ruled by gravity until it eventually hits the ground.
The range or maximum horizontal distance d traveled by the object can be calculated as follows:
[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]
Birdman flies horizontally at a speed of v=40 m/s and a height of h=58 m. He releases a turd above the start of the field. If the robot was exactly down Birdman, then it won't catch the turd with the bucket because it would land farther away by a distance equal to the range. Thus:
[tex]\displaystyle d=40\cdot\sqrt{\frac {2*58}{9.8}}[/tex]
[tex]\displaystyle d=40\cdot\sqrt{11.84}[/tex]
d = 137.6 m
The robot should hold the bucket at 137.6 m from the start of the field

According to Kepler's second law of planetary motion,
O a. planets maintain constant speed around the Sun.
Ob. the area swept out by the orbit per time unit keeps changing.
O c. the speed of a planet is greatest when it is closest to the Sun.
O d. planets maintain constant acceleration around the Sun.
Answer:
c. the speed of a planet is greatest when it is closest to the Sun.
Explanation:
Johannes Kepler was an astronomer who discovered that planets had elliptical orbits in the early 1600s (between 1609 and 1619).
The three (3) laws published by Kepler include;
I. The first law of planetary motion by Kepler states that, all the planets move in elliptical orbits around the Sun at a focus.
II. According to Kepler's second law of planetary motion, the speed of a planet is greatest when it is closest to the Sun.
Thus, the nearer (closer) a planet is to the Sun, the stronger would be the gravitational pull of the sun on the planet and consequently, the faster is the speed of the planet in terms motion.
III. The square of any planetary body's orbital period (P) is directly proportional to the cube of its orbit's semi-major axis.
Answer:
A planet moves faster when it is closer to the Sun.

A loudspeaker produces a sound wave of frequency 50hz.
The amplitude of sound wave is increased.
What is heard?
A) a louder sound of higher pitch.
B) a louder sound of the same pitch.
C) a sound of higher pitch but the same loudness.
D) a sound of the same pitch and loudness as before
Answer:
B) a louder sound of the same pitch.
Explanation:
Given that the loudspeaker produces a sound wave of frequency 50hz and the amplitude of the sound wave is increased.
As loudness of the sound depends on the amplitude of the sound while pitch depends on the frequency of the sound.
On increasing the amplitude of the sound there is no effect on the frequency of the sound, so, the loudness of the sound will increase while the pitch remains unchanged.
Therefore, on increasing the amplitude of the soundwave a louder sound of the same pitch is heard.
Hence, option (B) is correct.

because of friction? A. energy is not always conserved
B. not all potential energy is converted to kinetic energy
C.all an object's kinetic energy turns into potential energy
D all of an object's potential energy turns into kinetic energy
Answer:
i think its B.NOT all potential energy is converted to kinetic energy
Answer:
Maybe, B. Not all potential energy is converted to kinetic energy.
Explanation:
Even if air resistance slows down the ball, the potential energy is the same. But if air resistance is in the way, not all of the potential energy can be converted to kinetic energy. Some of the energy has to be used to push the air molecules out of the way.

Mr. D's dog Gromit jumped out of a second story window (through the screen) and fell to the ground below. The window is 15 feet high, the acceleration of gravity is 9 m/s', and there are 3.28 feet in each meter. What was the final velocity of this crazed dog? (True story, don't worry he's fine and now he knows about gravity)
Answer:
Vf = 9.46 m/s
Explanation:
In order to find the final velocity of the dog we can use third equation of motion:
2gh = Vf² - Vi²
where,
g = acceleration due to gravity = 9.8 m/s²
h = height of window = (15 ft)(1 m/3.28 ft) = 4.57 m
Vf = Final Velocity of Dog = ?
Vi = Initial Velocity of Dog = 0 m/s
Therefore,
(2)(9.8 m/s²)(4.57 m) = Vf² - (0 m/s)²
Vf = √(89.572 m²/s²)
Vf = 9.46 m/s
explain the universal law of gravity and it's calculate from as well as the value of g
Answer:
According to the Newton's law of gravitational every object in the universe attracts every other objects with a force which is called gravitational force.This gravitational force is (i) directly proportional to the product of their masses and (ii) inversely proportional to the square of the distance between their centres.
Explanation:
Newton's law of gravitational is called the universal law because it is applicable to all the bodies either terrestrial or celestial having any shape,size,mass or at any distance apart with any medium between them,at any time(past,present or future).
