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.
1. red blood cells
2. diploid is a type of cell with two sets of chromosomes (usually from the mother and farther)
haploid is a sex cell, so it is a cell with a single set of chromosomes (egg and sperm cells)
Answer:
<em>The total amount of energy transferred during photosynthesis for this ecosystem equals</em><em> 260,000 kcal/m2/yr.</em>
Explanation:
To answer this question, we need to know that
- gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesis
- net primary productivity (NPP) = difference between GPP and respiration rate
So, to calculate GPP we need to sum NPP to Respiration rate. This if,
NPP = 165,000 kcal/m2/yr
R = 95,000 kcal/m2/yr
NPP = GPP – Respiration
Then,
GPP = NPP + R
GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr
GPP = 260,000 kcal/m2/yr
