Answer: The drive theory of motivation.
Explanation:
The drive threory of motivation is based on the principle that organisms have certain psycological or physiological needs (in this case, hunger). When those needs are not satisfied, a tension in the organism is produced, and with it a drive to seek the satisfaction of that need.
Because the substance the rat recieves is nonnutritive (it doesn't reduce the rat's hunger), we can clearly see that the rat isn't performing the response because of this drive, seeking for the satisfaction of its hunger, but is motivated by another feeling. Therefore, this observation is problematic for the drive theory of motivation.
You can put wind energy propellers on the front of your car. This would be effective, as the high speed of the car would increase the rate of energy produced.
You could also have a metal rod slightly scraping the ground, and take the heat generated by friction to produce energy.
Hope this helps!
The answer is phagocytosis.
<span>Phagocytosis is a process which amoeba uses to swallow up large fragments of matter, such as mineral particles, dead cells. These swallowed fragments form a phagosome. The phagosome fuses with a lysosome and forms a phagolysosome inside which enzymes break down those fragments.
Phagocytosis is a specific form of endocytosis.</span>
The answer is 4 diploid cells.
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces <em>two haploid cells</em>.<span> Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. This is achieved through suppression of DNA replication between two meiotic divisions.
If there were no </span><span>suppression of DNA replication, then meiosis I would produce <em>two diploid cells</em>, and after meiosis II there will be four diploid cells.</span>
