in experiment 1, which of the following factors was systematically changed so that its effects could be observed? A.light intens

Stels [109]

Explanation:

A.light intensity

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

At the compensation point, the rate of CO2 production by respiration matches the rate of CO2 utilization in photosynthesis- there is no net CO2 production . Since photosynthesis is rate limited, the rate of energy intake can be reduced in order to reach the compensation point; lowering the light intensity would slow the rate of photolysis and thus photosynthesis. Similarly, an increase in light intensity

increases the rate of photosynthesis- the CO2 level would be reduced as more inorganic CO2 is fixed, together with producing O2 as waste.
would increase the temperature of the environment- light energy is converted to heat energy which increases temperature.
lead to higher levels of humidity- the heightened temperature increases the rate of evaporation of water from tissues, and thus increases the humidity (water vapor content of the surrounding air)

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

Dton

Dafna11 [192]

Answer:

polypeptides

Explanation:

Amino acids generally represent the building blocks of proteins. In order words, proteins are polymers of amino acids.

The amino acids in proteins are linked together by peptide bonds. A peptide bond is formed between two amino acids when the amine group of one of the amino acids combines with the carboxylic group of the other with the elimination of water. When the reaction involves multiple amino acids, multiple peptide or polypeptide, also known as protein is formed.

One of the most important scientific discoveries was penicillin. Research the discovery of penicillin, what produces this drug,

artcher [175]

Answer:

It is essentially a broth culture filtrate of the penicillium mould.

Explanation:

Alexander Fleming invented penicillin an antibiotic in 1928. These have been rated as the most important scientific discovery, being among the first antibiotics to be effective against bacterial infection.

Penicillin belongs to different families that are selective against a large variety of bacteria.

In fact, this antibiotic was discovered by fleming and accident in which he left a platter containing staphylococci open and was contaminated by green mould. There was an area of inhibited bacterial growth around the mould from which he inferred that the mould produced a material that inhibited bacterial growth. This was found to be a penicillium mould through further study.

I assume penicillin is the most significant discovery so far because it was the first antibiotic ever discovered against bacterial infection in the absence of any drug.
