Some microbes can kill or inhibit the growth of other microbes led to the development of the first antibiotic.

Answer: Option A

<u>Explanation:</u>

Antibiotics are the substance that restricts the bacteria growth and replication. These are designed against microbes and it targets bacterial infections in or on a human body. Bacteria's comes under the microbe category that cause harm to the human body.  

The substance that targets, restricts and kills microbial cells includes antibiotics, antiseptics and antiviral. The antibiotics that we use today can be produced in labs and they can be found in nature also. Hence, antibiotics are the one that kills or restricts the microbe's growth.

Either Solute or solvent may have hydrogen bond in it but another one has opposite. So, in situation of un-like characteristics, they can't dissolve by any means!

Hope this helps!

Two identical metal spheres a and b are connected by a plastic rod. both are initially neutral. 1.0×1012 electrons are added to
Ann [662]
The plastic rod is made of insulator (plastic), so it does not allow charges moving from one sphere to another. This means that all the electrons given to sphere A will remain on sphere A.

The number of electrons initially given to sphere A is N=1.0 \cdot 10^{12}, and since the charge of 1 electron is e=-1.6 \cdot 10^{-19} C, the net charge left on sphere A after the removal of the rod will be
Q=N e = 1.0 \cdot 10^{12}(-1.6 \cdot 10^{-19} C)=-1.6.0 \cdot 10^{-7} C

A student uses a microwave oven to heat a meal. The wavelength of the radiation is 8.97 cm. What is the energy of one photon of
krek1111 [17]

Answer:

The energy of one photon is 2.21x10⁻²⁴ J. Multiplied by 10²⁵ is 22.10 J.

         

Explanation:  

The energy (E) of a photon is:

E = h\frac{c}{\lambda}

Where:

h: is the Planck's constant = 6.62x10⁻³⁴ J.s

λ: is the wavelength of the radiation = 8.97 cm

c: is the speed of light = 3.00x10⁸ m/s

E = h\frac{c}{\lambda} = 6.62 \cdot 10^{-34} J.s\frac{3.00\cdot 10^{8} m/s}{8.97 \cdot 10^{-2} m} = 2.21 \cdot 10^{-24} J

Hence, the energy of one photon is 2.21x10⁻²⁴ J.

Now, if we multiply the answer by 10²⁵ we have:

E = 2.21 \cdot 10^{-24} J \cdot 10^{25} = 22.10 J

I hope it helps you!
