Well, you just have to look for the one that does not have any positive/benefit.
1. is not the answer, since vaccines prevent countless people from disease and death.
2. is not the answer since animal abuse is not okay and the statement shows that science has become more efficient, therefore helping society become more efficient
3. is definitely not a positive effect that biotech has had on society. antibiotic-resistant bacteria endangers everyone. Therefore, this is the answer :)
4. is not the answer because helping people with diabetes be able to afford their medication is very helpful.
Create your conversion factors.
You know that 1 micrometer = 1/1000000 m
Then,
[1 micrometer]^2 =[1/1000000 m]^2 =>
=> 1 = [1000000]^2 micrometer^2 / m^2
Now multiply the given area times your conversion factor:
1.50 (micrometer)^2 * [1/1000000]^2 micrometer^2 / m^2 = 1.50*10^(-12) m^2
Answer: 1.50*10^(-12) m^2
Metallic bonding
The particles in a metal are held together by metallic bonds.
High melting and boiling points
Metallic bonds are strong and a lot of energy is needed to break them. This is why metals have high melting points and boiling points.
Conducting electricity
Metals contain electrons that are free to move in the metal structure, carrying charge from place to place and allowing metals to conduct electricity well.
Metallic bonding - Higher tier
Metallic bonding is the strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons.
No mutations that neither benefit nor harm the organism has no effect on the organism's survival.
Explanation:
The neutral mutations do not cause any effect on the organism they occur. They are called silent point mutations because they do not code for the amino acid change in the proteins.
They have no effect on the organism's survival neither beneficial nor harmful effect.
The neutral mutations do not affect the process of Natural selection.
Answer:
The wavelength of the light passing through it. (Ans B).
Explanation:
The refractive index of a substance is defined as the ratio of the speed of the light present in the vacuum to the speed in the medium. Refractive index of a substance is called as a dimensionless number that helps to describe how fast light will travel through the substance. It is described as:
N = C/V,
Where C is known for the speed of the light in vacuum, and V is known as the phase velocity of light which is found in medium.
