What do you already know about photosynthesis and cellular reputation? (At least three sentences) BRAINLIEST INVOLVED AND
Vilka [71]

I'm not sure what YOU already know about photosynthesis and cellular respiration.... however, you SHOULD know that the two are beautifully linked to one another!

Photosynthesis equation:

6CO2+6H2O -> C6H12O6+H2O

Cellular respiration

C6H12O6+H2O -> 6CO2+6H2O

Notice something? The substrates of one equation are the products of the other! We rely on plants for their photosynthetic reactions - and plants benefit from us (not really because there is already a TON of CO2 in the atmosphere) from our cellular respiration

***we like their oxygen and they like our carbon dioxide!

:) I hope that helps! Let me know if you need any more elaboration!

What two substances are we concerned about over-nourishing our water sources and ultimately leading to eutrophication?
expeople1 [14]

The correct answer is - nitrogen and phosphorus.

The nitrogen and the phosphorus are the two substances that cause most of the eutrophication. It is good for the organisms that live in the water when these two substances are available as they are very important nutrients, but if the optimal amount is surpassed than it can be devastating. When there's high quantities of nitrogen and phosphorus in the water it makes it much more rich in nutrients that it should be. That kind of situation is the best for the algae, which start growing all over the place, quickly covering the water and becoming the dominant life form. As that happens, the organisms that use photosynthesis will die out because the Sun will be blocked, and the algae  will also contribute to a big reduction of the oxygen in the water too. The end result being totally destroyed ecosystem that has been overtaken by algae.

Which molecules does a cell need from food to make these membrane
Yuliya22 [10]

Answer: The organic molecules required for building cellular material and tissues must come from food. Carbohydrates or sugars are the primary source of organic carbons in the animal body. During digestion, digestible carbohydrates are ultimately broken down into glucose and used to provide energy through metabolic pathways.

Hope this helps...... Stay  safe and have a Merry Christmas!!!!!!!! :D

What was the actual proportion of the basis for equal amounts of DNA
Stells [14]

Answer:

Equal amounts of DNA contain equal proportions of nitrogenous bases.

Explanation:

According to Chargaff's rule, the nitrogenous base pairs (Purines and pyrimidines) have an equal ratio (1:1) in the DNA of all the organisms. More precisely, the amount of adenine is equal to thymine and the amount of guanine is equal to cytosine in the DNA of all the organism. A-T base pair has two H-bonds while G-C base pair has three H-bonds.
