It’s an abiotic factor because it’s not living.
The correct answer is "C."
mRNA stands for messenger Ribonucleic acid. The role of mRNA is to carry genetic information for the synthesis of protein from the nucleus after transcription.
After the transcription process is over, the mRNA leaves the nucleus and heads to the ribosomes in the cytoplasm where translation of this information takes place.
The ribosomes are the work bench of the cell. They receive the mRNA with its coded information, read it and translate it and with the help of tRNA (transfer RNA), amino acids are fetched from the cytoplasm and linked together to form the exact protein that was coded for on the mRNA.
Answer:
It processes the environment and sends out signals.
Explanation:
Sense receptors can sense any changes in internal or external conditions which disturb the homeostasis. The sensory information is sent to the central nervous system which in turn process the information and commands the respective body parts to perform actions to restore the homeostasis.
Example: The information about increased demand of oxygen during exercise is sent to the brain which in turn commands parts of breathing system and cardiovascular system to increase the breathing rate and heartbeat rate respectively to compensate for increased oxygen supply.
Answer:
According to collision- coalescence theory, formation of raindrop from cloud droplets occurs when cloud droplets collide and coalesce or stick together.
Explanation:
- The only significant difference between a raindrop and a cloud droplet is that a raindrop consist of a velocity that is non-negligible during the fall.
- Larger droplets having higher terminal velocities fall faster and collide with smaller droplets. Often the cloud droplets stick together and coalesce to form a larger droplet.
- This starts a chain reaction where these bigger droplets fall even rapidly, collide with the other droplets in their path and merge with these droplets.
Answer:
true
Explanation:
blood from heart to body, blood from body to other arteries back to heart and then pumps back into your body again, repeating the process over and over again
