Explain how each of the following factors affect the rate of photosynthesis 1) temperature 2) inorganic ions
​

Answers

Answer 1
The main variables which affect photosynthesis are light, water, CO2 concentration and temperature.
On a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg Mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis, though these are rarely covered in discussion of this topic.
The thing is that photosynthesis will be held back by whichever factor is in shortest supply.
As I sit in my study in England, the sun is shining brightly, but the temperature outside is only 5ºC. I suspect the rate of photosynthesis is limited by temperature today.
Yesterday was a dull day, but in the middle of the day it was not cold and I suspect there wasn't enough light for photosynthesis. If I had turned the security lights on my house on, the plants in my garden might (possibly) have photosynthesised faster.
In summer, some farmers growing crops in glasshouses actually increase the amount of carbon dioxide in the air as all their plants have plenty of water and light and the temperature is near the best possible for photosynthesis.
A good way to investigate this might be with the help of algae and you can use the 'Immobilised Algae' practical for this.
Although water is needed as a raw material for photosynthesis, don't bother trying to investigate water as a variable - plants normally wilt and wither long before water restricts photosynthesis at the biochemical level. They need water to support the plant to face the sun as well as a raw material of photosynthesis.
The simplest equation for photosynthesis:-
Carbon dioxide + water -----(in light, with chlorophyll and enzymes)----> sugar + oxygen
Temperature speeds up all chemical reactions - photosynthesis is no exception.
Enzymes work better in warm conditions (up to about 50ºC when enzymes start to be destroyed by heat).
The idea to get across is that different conditions will be most important on different occasions. This morning, my garden could do with more warmth - yesterday, it could do with more light / sun!

Answers

Answer:

C!!

Explanation:

It's not B because it's located in the great plains. Not D because in 50 years, 70% of the aquifer will be gone. Not A because water use isn't regulated.

Ogallala Aquifer is the rock holding the groundwater in the Great Plains of America. The Ogallala Aquifer is running out of water.  Thus, option C is correct.

What is Ogallala Aquifer?

Ogallala Aquifer is an underground layer of water that is held by the rocks, pebbles, and gravel that make the water well above the surface. It is not beneath the East Coast but is situated on the Great Plains of the United States.

It has been reported that the water usage of the Ogallala Aquifer is not regulated and hence it does not have enough water to last up to 6,000 years. At approx 70%, the water of the aquifer will be soon gone resulting in the deprivation of the water.

Therefore, option C. the Ogallala Aquifer is running out of water is correct.

Where do the thickest deposits of terrigenous sediment typically form?
A. deep-ocean trenches, such as the Mariana Trench
B. mid-ocean ridges
C. abyssal plains
D. continental margins near the mouths of rivers

Answers

Answer: D. continental margins near the mouths of rivers

Explanation:

Terrigenous sediments are those that are formed via processes on land as opposed to in water. They result mostly from the erosion of rocks and yet make up 20% of all ocean sediments.

Continental margins near the mouths of rivers contain the thickest deposits of this sediments as they are closest to land which is the source. It is made more convenient by the presence of rivers bringing the sediments to them when the rocks are eroded.
