Answer:
The correct answer is OPTION B (b. Yes—the initial infection might be acute but the virus can later become latent by becoming integrated into the host cell genome).
Explanation:
The hepatitis B virus has an unusual feature similar to retroviruses. This makes it deadly and difficult to treat when it is at an advanced stage. It basically attacks the liver and can cause both an acute and persistent infection.
In the acute stage, the cells are newly attacked and the body is fighting it off, the symptoms might start showing depending on how long it has invaded the body. These symptoms include dark urine, vomiting, yellowing of the skin and eyes (jaundice), the liver can still fail at this stage causing death.
At the persistent stage, which is already chronic, the invaded cells have been weakened, the symptoms are slow to resolve therefore it is in a prolonged stage which can lead to liver cancer and eventual death.

Answer: Studying botany helps companies develop more abundant food crops for less investment
Explanation:
The reasons for studying botany that is most directly related to increased profits was that "Studying botany helps companies develop more abundant food crops for less investment".
Since more food crops are gotten for less investment, it ultimately means that there'll be a reduction in the cost which will hence lead to an increase in revenue and therefore there'll be an increase in profit.
The biological macro molecule is CARBOHYDRATE.
Carbohydrates are made up of just three elements, which are carbon, hydrogen and oxygen, all joined together in a ringed structure. The number of carbon a carbohydrate has determined the class of carbohydrate under which it is grouped. The particular one we are given in this question has five carbon, so it is a pentose sugar.
Carbohydrate are the major source of energy in the living cells.
Observational learning is also known as social learning theory.
<h3>What is observational learning?</h3>
Observational learning is to the process of learning by the watching the behaviors of the others. The targeted to the behavior is watched, memorized, and then it is mimicked. Also known as the shaping and modeling, observational learning is to the most common in to the children as they imitate by the behaviors of adults.
Observational learning, also this is called social learning theory, occurs when an observer's behavior of changes after viewing the behaviour of any components. An observer's of the behavior can be defined and affected by the + or - consequences--called by the vicarious and reinforcement or vicarious of the punishment-- of a model's behaviour.
