Capsid is the component of a virus that is lacking in its cell
A capsid is the protein shell that surrounds a virus. Capsids functions by protecting the nucleic acids of a virus while interacting with the host environment. Capsids are made up of many oligomeric structural subunits that contains the protein; protomers. Capsids are generally grouped based on their structure. The common ones are helical and icosahedral.
Answer:
it is a catecholamine that stimulates alpha1 adrenergic receptors and, slightly, beta1 adrenergic receptors, without beta2 effect. It is the vasoconstrictor drug par excellence.
Answer:
a. food pellet
Explanation:
In classical conditioning, an unconditioned stimulus is the stimulus that naturally elicits an unconditioned response. The unconditioned stimulus is usually paired with a neutral stimulus, and after pairing with a neutral stimulus, the neutral stimulus becomes a conditioned stimulus that elicits a conditioned response alone.
In the experiment described above in the question, <em>the unconditioned stimulus is the food pellet,</em> which naturally elicits the response of the rat to wait at the far left corner of the cage. The neutral stimulus which is paired with the food pellet is the vanilla scent, which now becomes the conditioned response, when paired alone.
Limited installation sites best describes a drawback in the scientists' plan because tidal energy is not present everywhere.
<h3>
Describes a drawback in the scientists' plan?</h3>
The big disadvantage of tidal power is that there are limited installation sites for it. It is expensive as well as the turbines can adversely impact the surrounding ecosystem.
So we can conclude that limited installation sites best describes a drawback in the scientists' plan because tidal energy is not present everywhere.
