Answer:
Option A, It makes them less dense than water, thus aiding in buoyancy
Explanation:
Lipids stored with in the body of planktons make them capable to float in water against the buoyancy force of water in the down ward direction by reducing the overall density of the planktons. Hence, option A is correct
An experiment is a procedure designed to test a hypothesis as part of the scientific method. The two key variables in any experiment are the independent and dependent variables. The independent variable is controlled or changed to test its effects on the dependent variable.
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.
The independent variable are the different types of sugar solutions: maltose, glucose, and sucrose.
<h3>What are variables in an experiment?</h3>
A variable is any factor in an experiment that can be manipulated, controlled for, or measured.
There are three types of variables in an experiment:
- Dependent variable
- Independent variable
- Constant variable
An independent variable is the variable that stands alone and is not affected by other factors in the experiment. Changes in this variable results in changes in the dependent variable.
In the given experiment, the independent variable are the different types of sugars.
In conclusion, changes done to the independent variable results in changes in the dependent variable.
