Answer:
In the decolorization step alcohol is used which destain the gram-negative bacteria but not gram-positive because alcohol degrades the LPS cell wall of gram-negative bacteria which allow the crystal violet to moves out of the cell.
So if we use too little alcohol then the alcohol will not able to decolorize all the gram-negative bacteria and most of the cell in the culture will appear violet or purple because crystal violet retained in the cell wall of bacteria.
So the sample of gram-negative bacteria will appear as gram-positive bacteria under the microscope.
Answer:
<u>Abiotic</u>: Clouds, rocks, wind, temperature, ocean currents, sunlight, topograhy, precipitation, air quality, soil, water, humidity, climate.
<u>Biotic</u>: Grass, wolves, fish, microbes, insects, trees, birds, moss, animals, bacteria, organic matter, plants.
Explanation:
Biotic factors are things that are or were once living. Abiotic factors are things that are not and never were living.
Answer:
here's your answer
Explanation:
the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.
Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves
=frequency of dominant allele
=0.0004
will be 0.02;frequency of recessive allele will be 0.02
