Answer:
mRNA or messenger RNA goes to ribosomes to dictate the genetic information that it contains .
Explanation:
Ribosomes act as work benches during protein biosynthesis.mRNA also called messenger RNA binds with the smaller subunit of ribosome at the time of translation.
The bound subunit of ribosome reads the genetic information as codons containing three concecuetive nucleotides present in mRNA thus helping tRNA to bring the particular amino acid specific for that codon at the A site or attachment site of ribosome.
Thereafter ribosome moves to the next codon to bring another amino acid and so forth.
Thus mRNA helps ribosome to brings the amino acids at the translation site.
True. Many innovators
and inventors have used new scientific methods to develop and improve
communication and transportation devices in many ways. They were able to either make them faster or
more fuel efficient. They have also
given rise to new ways to communicate such as the internet and have developed
devices that make it easier for people to come together.
Answer:
A
Explanation:
Living organisms adapt to their moves and positions in response to the environmental changes for their protection or to their advantage. When an entity reacts to the changes in its surroundings, it is referred to as stimulus while the reaction to the stimulus is referred to as a response. Common stimuli are sound, light, air, heat, smell, taste, water and gravity.
Think of burning your finger of fracturing your bone without any pain sensation. It may certainly sound like a superpower or an ideal situation, however, when it comes to the standpoint of survival, it can be disastrous.
It is a characteristic behaviour of living entities to respond to stimuli with the intervention of the Nervous System. It is an organ system ascribed to send signals from the spinal cord and the brain throughout the body and then back from all the body parts to the brain. Neuron acts as the mediator and is the basic signalling unit of the Nervous system.
Pain is the body’s way of letting us know that something is not right. It can prevent further injuries or push us to seek medical attention. Moreover, all of this is possible because humans can respond and react to stimuli due to control and coordination among the various organs and organ systems.
Control and Coordination in simple multicellular organisms take place through only the Nervous system which coordinates activities of our body. It is the control system for all our actions, thinking, and behaviour.
The relationship between the food we eat and the energy in our bodies is that food is converted to energy and without food we will not have energy, I think hopes this helped you out a little.
