Explanation:
If water were a nonpolar molecule how would its properties be different A. Water would be able to climb inside plants. ... Water would stick together much more strongly.
Answer:
The molecules of cold water are moving slower and are a little closer together. If students do not notice a difference, move the slider all the way to the left again and then quickly to the right.
Explanation:
Answer:
C. 3, 2, 1
Explanation:
During a single PCR cycle, the very first step is the heat separation of the double stranded DNA. Primer binds only single stranded DNA/RNA because it has complimentary bases which match single strand of DNA/RNA that is why it is necessary to unwind both the strands of DNA by providing temperature.
As soon as the DNA strands have separated by increasing the temperature to ~ 95 °C, in the next step the primer binds the portion of DNA which is complimentary to the bases of the primer. In order for primer to bind DNA, the temperature is lowered to ~ 72 °C and the process is called as annealing.
Once primer has bound to the DNA, the next step is polymerization i.e. nucleotides which are the monomer units of DNA are added one by one with the help of enzyme named as Taq polymerase. This is how the strand extends ahead of primer and exact copies of the given DNA are produced.
Note: PCR may be considered as in vitro DNA synthesis or replication.
Answer:
C) Acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
Explanation:
Acceleration is defined as the rate of change of velocity per unit of time and velocity is defined as the speed of something in a given direction. The car is on a circular track, so it is constantly changing direction and therefore is constantly changing in velocity and accelerating. With this, we can eliminate choices A, B, and D since they either state that the car is not accelerating or not changing in velocity, leaving us with choice C) Acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
please lmk if i made any mistakes, hope this helps you :)
