False , because its backwards
There will be more energy 'locked away' in a massive lorry that is moving at 20 m/s than in a motorbike travelling at the same speed.
Also the faster it goes the more kinetic energy the lorry will have.
A lorry moving at high speed will have much more kinetic energy than a lorry moving at low speed.
Therefore a fast moving car or lorry will cause more damage in an accident than a slow moving one because this kinetic energy has to be turned into other forms including sound, heat and stress on the other vehicles.
The kinetic energy of an object therefore depends on two things:
(a) the mass of the object (m)
(b) its speed (v)
The formula for kinetic energy of an object of mass m travelling at speed v is:
<span>Kinetic energy (k.e) = 練v<span>2</span></span>

Answer:
Molecules carrying amino acids are positioned in the ribosome’s two docking sites.
Explanation:
A ribosome is a molecular machine that coordinates protein assembly.
- A ribosome brings together correctly the mRNA, which needs to be translated, and the tRNA, which assists in the translation process, to come together correctly.
- During translation, tRNA molecules carrying amino acids are positioned in the ribosome’s two docking sites.
- After the translation, the tRNA disassemble and is being reused many times.
Answer:
Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.
Explanation:
Answer: No, mRNA ( messenger RNA) model does not closely resemble the DNA strand from which it is transcribed.
This is because mRNA strand is complementary to the strand of DNA template that is used in its synthesis during the process called transcription. The polarity of DNA template is 3' to 5' whereas that of mRNA transcribed is 5' to 3' that is both the strands have antiparallel polarity.
This is the reason template DNA is referred antisense. mRNA strand more closely resembles the sense strand ( which is complementary strand of DNA template in a double helix).
