Answer:
In this case, the option D "Try repositioning the hearing aid or remove it and turn down the volume" is correct
Explanation:
Hearing Aid:
It is such a device that is used by the people who have some hearing problem.
It is a simple electronic device that has a Microphone that receive the sound from other person which is send to the Amplifier that amplifies the sound and send to the speaker so that the person with the hearing aid can listen the sound easily.
- The option A is not correct as whistling sound give us a clue that batteries are not depleted.
- We can't turn up the volume as doctor can still listen the whistling sound but the 70-year old is not listening his sound so there is noise is in hearing aid.
- We can't use pen and pencil as it will difficult to write for a 70 year old person and will make conversation difficult.
- We can change the position as mentioned in option D or remove the hearing aid turn the volume down so that the old man can listen clearly.
In this question there are many possibilities available. First one can be the presence of only a few organelles in prokaryotes than in eukaryotes.
The most important one however is the form of DNA which circular in prokaryotes and found in chromosomes for eukaryotes
Answer:
Four daughter cells are produced each with 40 chromosomes. The daughter cells would exhibit genetic variations and would not be genetically identical to each other.
Explanation:
Meiosis is a cell division that forms four daughter cells from one parent cell as two sequential division meiosis I and meiosis II do not include any DNA replication between them. Crossing over during prophase-I of meiosis-I includes the exchange of genetic segments and occurs between the homologous chromosomes. It produces new gene combinations in the daughter cells which were otherwise not present in the parent cell.
Since there is no DNA replication between meiosis I and meiosis II, the daughter cells have half the number of the chromosomes compared to the parent cell. This occurs as homologous chromosomes move towards the opposite pole during anaphase I.
Therefore, a parent cell with 80 chromosomes will make a total of 4 daughter cells by meiosis. Each daughter cell would have 40 chromosomes. These daughter cells would have some new gene combinations and would be genetically dissimilar among themselves.
The birds, because we can see from the food web that the bird eats both grain, a producer, and grasshoppers, a consumer.
1. four, bond
2. Cohesion
3. Adhesion is correct ... looked in my bio book sorry
