Answer:
Pertussis.
Explanation:
Vaccine is given as the preventable measure for the particular disease. Vaccine may contain the weakened or killed antigen, the epitope part of any antigen and the particular DNA or protein.
Pertussis is also known as whooping cough that affects the respiratory system of an individual and can cause pneumonia as well. The vaccine for the pertussis is available in the hospitals for the prevention of pertussis in the future generation.
Thus, the correct answer is pertussis.
The solutions will try and equilibrate. This means the higher solution will enter the cell via osmosis. The cell will then burst (lysis) or, if it is a plant cell, will become turgid.
Answer:
<em>Well, Animals in temperate deciduous forests have to adapt to changing seasons. They must be able to cope with cold winters and hot summers. Some animals hibernate or migrate during the winter to escape the cold. This is an essential adaptation because black bears often live in hollowed trees. Hope That Helps!</em>

Answer:
15. Current increases
16. 4 Amp
17. Current decreases
18. A direct relationship
19. voltage affects current
20. Current is unchanged
Explanation:
First you need to know about Ohm's Law. Ohm's law can be summarized in the formula:
where:
V = Voltage
I = Current
R = Resistance
As you can see, when you increase the voltage, the current increases as well. When you decrease the resistance, current increases as well. This means that voltage has a direct relationship with current, and current has an indirect relationship with resistance.
Voltage is the potential, or electrical potential energy that pushes the current along a circuit. THe current is the flow of energy, so it is actually the rate of electrical energy that goes through a point in a circuit over a period of time. The resistance is the resistive force, that the current goes through as it goes through a circuit.
Let's apply that to question 16:
Our given:
V = 6V
R = 1.5Ω
In question 17,just to show you, we can solve it and compare:
<u>6 V battery and 3Ω resistance:</u>
<u>3 V battery and 3Ω resistance:</u>
Current decreases from 2A to 1A.
Let's try it on Question 20:
<u>12V and 5Ω</u>
<u>6V and 2.5Ω</u>
There is no difference.
