Answer:

The correct option is : B. Acids and bases will neutralize each other.

Explanation:

Acid is a proton donor and electron-pair acceptor. Whereas, a base is a hydroxide ion donor and electron-pair donor.

The addition of an acid or a base can affect the pH of a solution. Acids lower the pH of a solution, whereas bases increase the pH of a solution.

The pH of an acidic solution < 7 and pH of a basic solution > 7.

When equal amounts of acid and base is mixed together, the solution gets neutralized. This is known as Neutralization reaction. The pH of such a solution is neutral (pH= 7).

Sexual reproduction produces genetically different offsprings which do possess variations, hence better chance to survive in the environment.

Option C

<h3><u>Explanation:</u></h3>

Sexual reproduction is the process of reproduction where there's a fusion of gametes from a male and female of the same species, resulting in a zygote and eventually an offspring. Sexual reproduction is very advanced type of reproduction which is very expensive for an organism. Much of the energy of the organism is spent to produce gametes and other necessary processes for reproduction.

Gametes of the sexual reproduction is produced mainly by means of meiotic cell division. This involves crossing over and chaismata formation which helps in genetic variations in the offspring. These variations help the species to survive unknown changes in environment, and helps to adapt quickly lessening the chances of extinction. So sexual reproduction has modified various times in different groups of species.

Regarding cellular phones, the __________ is a code used to reset a forgotten pin.
tekilochka [14]

Regarding cellular phones, the <u>electronic serial number (ESN)</u> is a code used to reset a forgotten pin.

  • An electronic serial number (ESN) is the distinctive identification number that the manufacturer embeds or inscribes on the wireless phone's microchip.
  • The ESN is automatically sent to the base station each time a call is placed so that the mobile switching office of the wireless carrier can verify the legitimacy of the call. In the field, the ESN cannot be easily changed.
  • The mobile identification number (MIN), which is used by wireless carriers to identify phones on their network, is different from the ESN.
  • To aid in preventing fraud, MINs and ESNs can be electronically checked.
