If you were making a product of artificial "Grow-Lites" for plants, what color light should

Biology
1 answer:
UNO [17]3 years ago
8 0

Answer:

<u>-blue and red light</u>

Explanation:

Plants produce sugars or carbohydrates during the process of photosynthesis. They absorb light energy from the electromagnetic spectrum with pigments within the thylakoid membrane, like chlorophyll a, chlorophyll b.

Chlorophylls are made of ringed molecules chlorine, a hydrogenated form of porphyrin with a magnesium ion bonded to four atoms of nitrogen. Chlorophyll a shows the most absorption of red light  (642 nm) and blue light (372 nm); while chlorophyll b shows the most absorption at 626 nm and 392 nm.  

Different types of chlorophyll sidechains change the molecules' absorption ranges; A's methyl group is bound at carbon 7,  B's aldehyde (CHO) ring is bound at carbon 7.  Both absorb light from orange-red and violet-blue wavelengths. As such, the best light wavelengths for photosynthesis are within the blue and red wavelengths (425–450 nm) and (600–700 nm).

Describe what happens to an enzyme after it has catalysed a reaction
victus00 [196]
Well during an enzyme catalyzed reaction the enzyme bonds with a specific substrate at the active site. This is called an enzyme-substrate complex. The substrate is converted into a specific product, but the enzyme remains unchanged. Enzymes accelerate reactions by factors of at least a million.Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over

Fishes are poor bioindicators of the environmental health of an aquatic system.
SVETLANKA909090 [29]

Answer:

b. False

Explanation:

Bioindicators are species, species groups or biological communities whose presence, abundance and conditions are biological indicative of a particular environmental condition. Bioindicators are important to correlate with a particular anthropogenic factor or a potentially impacting natural factor, representing an important tool in assessing the ecological integrity (health status of an area, defined by comparing the structure and function of a biological community between a impacted area and reference areas).

Contamination of aquatic environments and water for public use becomes a growing problem as human population growth expands, as does the demand for sufficient and quality water. Fish are very sensitive to contamination of aquatic environments and are therefore strong bioindicators of the environmental health of an aquatic system.
