Answer:
be heritable and be an advantage to offspring
The answer is tunicates. Tunicates are commonly known as sea squirts and are in the Chordata phylum, even though they don't have a back bone. Which is really weird. But they just got put into the same category as humans. This is because they have a notocord and a back bone when they are larvae. But they lose all these when they become adults.
Ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
<span>As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.</span>
Answer:
The correct sequence is 21543.
Explanation:
The procedure by which the signaling molecules known as neurotransmitters are discharged by the neuron's axon terminal and combines and reacts with the receptors present on the dendrites of another neuron or postsynaptic neuron is termed as neurotransmission.
The following are the steps followed in the process of neurotransmission:
a. Exocytosis of neurotransmitter gets stimulated by calcium.
b. The diffusion of neurotransmitter takes place across the synaptic cleft.
c. The binding of neurotransmitters takes place with the receptor.
d. After the binding opening of ion channels takes place.
e. The permeability of the postsynaptic membrane gets changed.
