It depends because there is many facts that can support many things of the safety of genetically and I do think that it is necessary to support the reason with evidence

i think sorry if i'm wrong.
Answer:
Tympanic membrane. (Ans. A)
Explanation:
Tympanic membrane: It is known as thin semitransparent eardrum, which is formed boundary between the external and middle ear. It's diameter is about 0.3-0.4 inch, and cone shaped membrane. Tympanic membrane is found in humans, and other tetrapods.
Its playing an important role in to transfer sounds which is present in the air to the ossicles inside the middle ear, then to the oval window of the fluid-filled cochlea.
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.
