Answer: Option (D) is the correct answer.
Explanation:
Non-metals are electron deficient in nature so, in order to complete their octet they need to gain electrons from metals or electron rich atoms.
Whereas metals are electron rich in nature so, in order to gain stability metals lose their valence electrons.
For example, atomic number of potassium is 19 and its electronic distribution is 2, 8, 8, 1. Whereas atomic number of chlorine is 17 and its electronic distribution is 2, 8, 7.
Therefore, sodium in order to gain stability will lose its valence electron to chlorine atom. Hence, an ionic bond will be formed resulting in the formation of KCl.
Thus, we can conclude that non-metals seek to gain electrons to have full outermost shells, while metals seek to lose electrons to have full outermost shells.
Mitosis produces cells that are genetically identical to the parent cell.
Meiosis includes two distinct processes that contribute to the generation of
genetic variation: crossing over shuffles alleles on the same chromosome
into new combinations, whereas the random distribution of maternal and
paternal chromosomes shuffles alleles on different chromosomes into new

D. greenhouse gases is the answer
A cochlear implant is an electronic device that bypasses the damaged portions of the ear and directly stimulates the auditory nerve.
<h3>Which is an electronic device that bypasses the damaged portions of the ear and directly stimulates the auditory nerve?</h3>
- A small, sophisticated electronic device called a cochlear implant can help people who are completely deaf or very hard of hearing hear sound.
- A second section of the implant is surgically implanted beneath the skin, while the outer portion lies behind the ear. Bypassing the ear's damaged areas, it instead stimulates the auditory nerve directly.
- A cochlear implant is a neuroprosthesis that enables someone with moderate to severe sensorineural hearing loss to hear sound. It is surgically implanted.
- With the help of therapy, cochlear implants may improve speech understanding in both quiet and noisy environments.
- Deaf people with cochlear implants can hear and understand speech. These gadgets do not, however, enable regular hearing. They are instruments that enable the processing and transmission of sound and speech to the brain.

F - Mammals are endothermic in that we produce our own heat internally from the food we eat and the oxygen we breathe.
