<span>The ribosomal RNA is especially useful for the study of phylogenetic relationships because ribosomal RNA are highly conserved.

It is very less that is why it is easy to compare. Ribosomal ribonucleic acid is the RNA component of ribosome which is essential for protein synthesis to all living organisms.

rRNA is widely used for the purpose of working out evolutionary relationships which are among organisms. </span>

When a neuron responds to a particular neurotransmitter by opening gated ion channels, the neurotransmitter is serving as which
GrogVix [38]

The question is incomplete as it does not have the options which are:

A) relay molecule

B) transducer

C) signal molecule

D) response molecule

Answer:

C) signal molecule

Explanation:

The transmission of signals in the neurons takes place in the form of electrical energy and chemical energy. The signals get transmitted in the form of electrical signals inside the neurons but when the signals have to be passed on to the next neuron on the pathway then the electrical signals get converted into the chemical signals.

The electrical signals cause the release of the chemical signals molecules called neurotransmitter from the synaptic vesicles in the presynaptic neuron and also opens the gated ion channels at the terminal. The neurotransmitter thus acts as a signal molecule in the transmission of a signal through neurons.

Thus,  C) signal molecule  is the correct answer.

Which statement describes the reaction for cellular respiration? The equation is carbon dioxide + water Right-arrow glucose + ox
ziro4ka [17]

Answer:

glucose + oxygen Right-arrow carbon dioxide + water and energy is produced in the form of ATP. This is the correct equation.

Explanation:

In cellular respiration -

If oxygen is present glucose molecules breakdown release energy in the form of ATP.

Here 1 glucose molecule in the presence of 6 oxygen molecules gives 6 carbon dioxide and 6 water molecules And 36 ATP as energy.

aerobic cellular respiration is very efficient in energy production as it gives high energy.
