Answer:
High-energy phosphorylated intermediates that serve as phosphate donors to ADP are generated as a result of electron-transfer reactions.
Explanation:
Peter Mitchell proposed Chemiosmotic hypothesis which state that the driving of the synthesis of ATP is accomplished by a proton-motive force. He propose that whenever electron is moved along the electron transfer chain then proton will be moved accross the inner part of mitochondria membrane. As a result of this there would be increase in PH of the mitochondria matrix and reduced PH of the intermembrane space.
Some Evidence about Chemiosmotic hypothesis hypothesis;
1)transportation of electron brings about the generatation of a proton gradient. there is difference in the PH on the outside and inside the mitochondria.
2)To synthesis ATP, a proton gradient is required only and other means by which PH gradient is generated
Therefore,High-energy phosphorylated intermediates that serve as phosphate donors to ADP are generated as a result of electron-transfer reactions is not Micheal Mitchell statement.
Answer:
C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation
Explanation:
Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.
The answer is; B is younger than D
In sedimentary rocks, the bottom layers are older that overlaying layers. This is because sediments are placed on top of each other by surface runoffs to ocean beds. Therefore, the first sediments to be deposited will always be towards the bottom as more and newer ones are brought in and deposited.
<h2>Exponential Population Growth</h2>
Explanation:
The model of exponential population growth predicts that the per capita population growth rate, r :
d. does not change as the population gets larger.
A population shows exponential growth if there is no limitation on growth. All members have abundant resource availability and the population displays its intrinsic rate of increase.This is also known as geometric growth .In geometric growth, rate of increase is expressed as a constant fraction or an exponent by which a particular population is multiplied.
Answer:
The population with the greatest genetic variation may have:
- The greatest number of alleles per gene
- The largest gene pool
Explanation:
A higher number of alleles will produce a higher total number of protein forms per gene. Moreover, the largest gene pool will synthesize the largest content of proteins, thereby increasing variation
