These are adenine and guanine.
Purines adenine and guanine are double ringed structures that make up DNA. Purines have a characteristic double-ring structure composed of carbon, nitrogen and hydrogen atoms.
Each of purine's rings contain two nitrogen atoms making up a total of four within the double ringed structure. The remaining five positions within the rings are occupied by carbon atoms. The purine ring is encircled by hydrogen atoms which can be replaced by other atoms or groups of atoms to form different purines.
Answer:
the wind carries abrasive materials
Explanation:
such as sand and salt over time theses small particles slowly strip way at the land form sculpting it by eroding the softer layers first
Answer:
Option B is the correct answer.
Explanation:
Let us consider 40 meter above ground as origin.
Initial velocity = 17 m/s
Final velocity = 24 m/s
Acceleration = 9.81 m/s
We have equation of motion v² = u² + 2as
Substituting
24² = 17² + 2 x 9.81 x s
s = 14.63 m
Distance traveled by rock = 14.63 m down.
Height of rock from ground = 40 - 14.63 = 25.37 m = 25.4 m
Option B is the correct answer.
Answer:
PLEASE MARK ME BRAINLIEST!!!
Explanation:
Given initial velocity of ambulance
v0=18m/s , acceleration a=5m/s2
To find distance, x=?
First we need to calculate the time for which it acquires 30\,m/s. For that use equation
v=v0+at
30=18+5×t
⇒t=30−185=125seconds
Distance travelled by the ambulance
x=v0t+12at2
x=(18×125)+12×5×(125)2
x=43.2+2.5×5.76=43.2+14.4
x=57.6m
Therefore the ambulance has to travel 57.6 m to match the velocity of car.
The answer is False, most asteroid can be found between Mars and Jupiter, commonly known as the asteroid belt. Asteroid found outside our our Solar System is called the "Kuiper Belt". further still there is more asteroid surrounding us called "Oort Cloud"
