Answer:
b) dumping used oil into street drains
Explanation:
protons, neutrons and electrons
Answer:
shortest wavelength of visible light: Violet
Energy that can be felt as heat but can't be seen: Infrared radiation
Short invisible rays that can cause damage to the eyes: Ultraviolet light
visible light with the longest wavelength: red 700
Explanation:
Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
The question is stated incorrectly. The correct question is as follows;
The site of intercellular communication between a neuron and another cell is the.
Answer:
Synapse.
Explanation:
Neurons have dendrites, cell body and axons. Millions of neurons are present in the nervous system. Different types of neuron are sensory neuron, motor neuron and interneuron.
Synapse may be defined as the gap between the two consecutive neurons. The junction between the two neurons that helps in the intercellular communication. The neurotransmitters are diffused directly and transmit information through these synapse.
Thus, the correct answer is synapse.
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.
