Answer:
<u>Part A</u> : 70 secondary oocytes will be formed.
<u>Part B</u> : 70 first polar bodies will be formed.
<u>Part C</u> : 70 ootids will be formed.
Explanation:
During oogenesis growth maturation of a single oogonium produces one primary oogonium.
the primary oogonium then undergoes meiosis -1 and produces one secondary oocyte and first polar body.
The secondary oocyte then undergoes meiosis - 2 and forms an ootid and second polar body.
The ootid then differentiates into the ovum.
As in the above scenario , 70 primary oocytes are present , they undergo meiosis-1 and produces 70 secondary oocytes and 70 first polar bodies. Hence answers of part A and B is 70.
As 70 secondary oocytes are formed , they undergo meiosis -2 and forms 70 ootids which then differentiate in 70 ovums.
Answer:
Cell division
Explanation:
Cells division leads to two daughter with the same genetic material as their "mother" cell.
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.

Answer:
e.) the biodiversity of the pond has decreased
Explanation:
Biodiversity or biological diversity refers to the variety of living organisms in a particular area. It can be a measure of number of species of living organisms in that area. The more the number of species, the higher the diversity and vice versa.
<em>Adjacent development close to the pond can be viewed as habitat disturbance. Habitat disturbance affects biodiversity in a number of ways including:</em>
- <em>A shift in the species composition of the habitat</em>
- <em>Outright extinction of certain species from the population</em>
<em>Overall, the species diversity become reduced as a result of a shift in species composition of extinction of some species. Hence, the best indicator of habitat disturbance is a decrease in biodiversity of the habitat.</em>
The correct option is e.
