Well the three products of photosynthesis are sugar, ATP, and oxygen. Hope this helps to a degree.
Answer:
Option (D)
Explanation:
Buffers are the chemicals (acid or base) that maintain the level of pH in the living organisms. Different types of buffers that are present in many organisms are bicarbonates ad bi-phosphates.
The phosphate buffer is comprised of inorganic phosphate (HPO₄²⁻) which can bind with free hydrogen when the level of pH is low or in a highly acidic condition. In case of an excessive pH condition or in a basic condition, the phosphates act as a buffer by releasing the hydrogen ions.
Thus, the correct answer is an option (D).
Answer:
This is an interesting thought experiment.
I am going to assume we are still human with similar heads/faces and digestive systems to what we have currently.
It would depend on what kind of tooth you picked.
With all incisor teeth we would be unable to grind up tough food and would have to swallow everything just as is on the end of the fork when you put it in your mouth (assuming you eat with a fork).
With all molar teeth we would not be able to bite through food very well. So cutting up food before you put in your mouth would become important.
The next issues are digestion. Chewing and breaking the food into small pieces is important in freeing up nutrients from food and making it digestable.
With a good knife and and a blender we could likely get around the digestive issues associated with not chewing our food or trying to eat large mouth fulls of food at once.
If you had a good sharp stone and another grinding pair of stones you could also achieve the desired consistency for food to provide energy and nutrients.
If you didn’t have tools it would be very hard get enough good food into your body. People still starve in 2017- there would be plenty more staving if you had to eat like this.
I also do not think that we would be able to produce speech as we do currently. We still would be able to speak but the sounds would be different.
The face would change. Particularly if we had molars everywhere.
Interesting idea. This would likely be evolutionary difficult/impossible.
Explanation:
Answer: 4%
Out of 5000kcal, the owl loses 2300kcal which mean it could only process 2700kcal. Out of 2700kcal processed, 2500 kcal is used for cellular respiration so there is 200 kcal used to make body cells. The production efficiency would be: 200kcal/5000kcal= 4%
