The correct answer is - A and B.
The nuclear energy can been seen at either way, and that is why it has both its supporters and its critics.
The nuclear energy is cheaper, cleaner, and nuclear centrals can produce much more and much more efficiently as well, so it can easily be seen why it can be extremely useful in a world where the energy demand is ever-growing.
On the other side, there's a huge risk with the nuclear centrals because if there's some problem, it can all turn into a catastrophe that will affect huge area. The consequences of a nuclear reactor exploding or leaking are long term, and takes lot of time that the area can be used for anything. Lots of human lives can be lost, and affected for numerous generations, as well as destroying the natural environment in a brutal way.
Answer:
This project is feasible because plants that don't have photorespiration are photosynthetically more efficient and have higher productivity compared to plants that undergo photorespiration
Explanation:
C4 plants are photosynthetically more efficient compared to C3 plants because these plants (C4) don't have photorespiration, which is a process that decreases the photosynthetic activity. Photorespiration is the process by which the Rubisco enzyme, which is involved in the first step of carbon fixation, adds oxygen to Ribulose 1,5-bisphosphate (RuBP), an organic compound involved in photosynthesis. This process (photorespiration) is known to waste energy generated by photosynthesis, thereby making photosynthesis less efficient. It is for that reason that C4 plants have high productivity. Some examples of C4 economically important crops include maize, sorghum, sugarcane, etc.
Hibernation helps animals survive the changing seasons. Foods that bears eat, such as berries and flowers, are much less available during cold winter months. When they hibernate, bears enter a deep sleep. ... While they sleep, the bears can survive because their bodies live off of their stored fat or food.
During hibernation, the animal’s body temperature, heart rate and breathing rate all drop to significantly lower levels. Animals do this to survive the winter because the weather is cold and food is scarce. It is advantageous because these animals can quite literally shut themselves off for weeks at a time rather than try and survive through harsh weather conditions.
While many people think bears are hibernators, they actually participate in a similar, though not exact, practice. Instead of hibernating, bears fall into a deep sleep called torpor. During torpor, heart rate and breathing rate decreases, body temperature reduces slightly and bears do not eat or release bodily waste. Bears can sleep more than 100 days without eating, drinking, or passing waste!
Bears sleep in dens that they make themselves, as well as in hollow trees, caves and dens built by other bears. A den can be built in 3–7 days, however, the timing of den building varies from bear to bear. While some bears build their dens months before hibernation season, others choose to excavate their dens.
These animals can dramatically drop their body temperature to below freezing—salty body fluids work to prevent tissue crystallization in particularly cold temperatures.
So really, animals that are true hibernators don’t actually sleep through the entire winter.
The urea produced by their fat metabolism is broken down and the nitrogen is re-used by the bear to rebuild protein.
To establish causation sociology, there are three key factors namely correlation, time order and ruling out alternative explanations. correlation gives the difference between the alternatives to be considered, time order gives the occurrence of events chronologically, finally, the ruling out alternative explanation gives one the chance to get the best alternative
Answer: A. Pyruvic acid, the product of glycolysis, is the starting block for both the Krebs cycle and fermentation.
Explanation: Glycolysis is a metabolic pathway that oxidize glucose producing pyruvic acid and few ATP molecules. If the cellular microenvironment is aerobic, pyruvic acid is converted in Acetyl coA and enters into Krebs cycle and later into electron transport chain, which produce large amounts of ATP. If the cellular microenvironment is anaerobic, fermentation occurs and pyruvic acid is converted in lactic acid, ethanol, etc, producing only few ATP.
