For each molecule of glucose consumed, the Krebs cycle occurs: D. twice
1 glucose --> 2 pyruvate, each one entering the Krebs as acetyl-CoA
Answer:
A Wheat Harvest System Simulation Model (WHSSM) was developed and used to study the effect of different climatic conditions on returns in three main wheat growing regions in Australia. The study was carried out using 15 years (1991–2005) historical weather data for Goondiwindi, Scaddan and Tamworth. It is found that the weather conditions during the harvest period could have a significant influence on the predicted returns. For the given farm setups, the optimum harvest moisture contents for different climatic regions were quite different. For the given control parameters, the optimum harvest moisture contents for Goondiwindi, Scaddan and Tamworth were 14, 15 and 17%, respectively. Growers in a dry and warm location (e.g. Goondiwindi) would be able to delay their harvests to a later date. They would also be able to gain a better return than growers in wet and cool regions (e.g. Tamworth or Scaddan). This paper highlights the importance of optimising the integration between agricultural machinery used, crop performance and perceived weather risk.

Answer:
answer is B
Explanation:
The answer is a negative feedback loop. Negative feedback is used to counteract an effect and achieve back a homeostatic balance. An example of a negative feedback loop is in thermoregulation. When temperatures are too high, the hypothalamus induces body responses such as vasodilation and sweating that enable the loss of excess heat.
Answer:
D. First law of thermodynamics
Explanation:
The first law of thermodynamics refers that energy can be tranferred or changed form one form to another but it can neither be destroyed nor be created. hence, it is also known as law of conservation of energy.
The equation ΔU = Q − W describes the first law of thermodynamics.
Where
- U is the internl energy of the system.
- ΔU is the change in U.
- Q refers to the total heat supplied into the system (include both addition and release of energy in the system).
- W is the net work done by the system.
Hence, the correct option is D.
