4. Use your knowledge about the relationship between nutrients and photosynthesis to explain the trends you observed in the data
Step2247 [10]

Answer:

The trends go up in the presence of nutrients.

Explanation:

There is a great relationship between nutrients and photosynthesis because photosynthesis can't occur without without the availability of nutrients. Plants uses carbon from the atmosphere which is a nutrient whereas other nutrients such as nitrogen, phosphorus, potassium etc from the soil with the help of the roots. If these nutrients are available in the surrounding, the plant produced more food during photosynthesis because these nutrients are the food of plants so the trends go up in the presence of nutrients and lowers down in the absence or lower concentration of nutrients.

Looking at the chemical reaction provided here, propose a different method that could be used to measure amylase activity: Starc
Anna007 [38]

Answer:

Starch + H2O = maltose

This reaction gives the Starch and H2O as the reactants and Maltose as the product.

Amylase is an enzyme which helps in the digestion of Starch molecules and its activity can however be measured through careful monitoring of the disappearance of amylase substrate which is in this case, starch.

When heart muscles cells are deprived of oxygen, the heart still pumps. what must the heart cells be able to do? transform lacta
katrin2010 [14]
The heart cells must be able to continue aerobic metabolism when skeletal muscle cannot. Aerobic metabolism is a part of cellular respiration and involves body cells making energy through glycolysis, the citric acid cycle, and the electron transport/oxidative. It is done in the heart at a rate below 85% of maximum heart rate and does not use vigorous muscle contraction. fatty acids , ketone bodies and carbohydrates are the primary substrates of the heart metabolized to generate ATP. The metabolic demands of the heart are the largest than any other organ in the body, and normal cardiac metabolism is required to fuel contractile function and viability.

Which of the reactions of photosynthesis require pigments absorbing solar energy?
ss7ja [257]

Answer:

During photosynthesis, a green pigment called chlorophyll is required to absorb solar energy. The reaction in photosynthesis that requires pigments to absorb solar energy is called LIGHT REACTION.

Explanation:

Light reaction is considered to be the first stage or phase during photosynthesis and the key elements that is needed for the reaction to take place is- sunlight and chlorophyll.  Chlorophyll is a pigment that makes the leaves of the plant appear green. There is also another important function of chlorophyll that is to trap solar energy during the process of photosynthesis to convert the trapped solar energy into chemical energy- ATP molecules. These ATP molecules then form glucose- food for the plant.
