Suppose you were interested in the effect of breastfeeding versus formula feeding on the composition of gut flora in newborns. As part of your experiment, stool samples from healthy babies in the study get plated on various agar media. You notice that greater numbers of colonies are recovered when samples are plated on blood agar compared to nutrient agar (NA). After some diligent subculturing, you isolate several bacterial species capable of slow growth on the blood but not on the NA. You correctly surmise that these organisms: ______________
a. are opportunistic blood pathogens.
b. have extensive and complex nutritional requirements not met by NA are inhibited by the ingredients in NA.
c. should be classified as beta-hemolytic.
d. grow because the blood agar suppresses the growth of faster-growing bacteria.

the process of activating photoreceptors by altering the photopigments is known as __________.
The process of activating photoreceptors by altering the photopigments is known as PHOTOTRANSDUCTION. It involves the mechanism by which light can be converted into electrical signals.
Phototransduction refers to the mechanism by which light can be converted into electrical signals.
Visual phototransduction occurs in the part of the eye known as the retina, in specific cells called photoreceptors and ganglion cells.
Photoreceptor cells include rod cells and cone cells, which are sensitive to light.

The one advantage of using this technology in a coal-burning power plant is that it does not emit greenhouse gases. Therefore, option C is correct.
How does electrical energy formed from moving water?Electrical energy can be generated from moving water through a process called hydroelectric power generation. Hydroelectric power plants use the kinetic energy of moving water to spin turbines, which in turn generate electricity.
Hydroelectric power generation is a renewable source of energy that produces no carbon emissions or air pollution. It is one of the most widely used forms of renewable energy, providing electricity to millions of people worldwide.
However, the construction of dams and reservoirs can have significant environmental impacts on the surrounding ecosystems and habitats. Hence, option C is correct.

If red blood cells are placed in distilled water and examined under a microscope
no cells are seen.
Explain why no red blood cells would be seen
Answer:
The distilled water made the red blood cells burst.
Explanation:
Distilled water is a hypotonic solution containing ZERO salt content. It is 100% water, making the red blood cells (RBC) take in water that causes the RBC to swell, then burst.

How do organisms depend on and compete for biotic and abiotic factors?
Your answer should include at least 6 sentences to explain the claim, evidence and reasoning.
Answer:
Organisms depend on and compete for both biotic and abiotic factors in an ecosystem. A few abiotic factors are sunlight, water, and territory. Plants compete for sunlight and water, and they depend on those factors for their survival. Biotic factors would include plants, bacteria, and other animals. Consumers of these biotic factors compete for them because they depend on them for their survival.

Which situation would increase the fluidity of a
phospholipid bilayer?
A. decreasing the temperature
B. increasing the number of proteins
C. increasing the number of cholesterol molecules
D. increasing the number of unsaturated fatty acids
Answer:
C
Explanation:
Cholesterol molecules stay in between fatty acid tails preventing them from sticking together
The situation that would increase the fluidity of the phospholipid bilayer is increasing the number of cholesterol molecules. The correct option is C.
What is a phospholipid bilayer?A phospholipid bilayer is a layer around a cell. The cell membrane is composed of a bilayer of phospholipids. It contains fatty acids and alcohol.
Bilayers of phospholipids are essential parts of cell membranes. The lipid bilayer serves as a physical barrier to the entry and exit of molecules and ions from the cell. However, allowing the selective transit of specific substances into and out of cells is a crucial role of the cell membrane.
Cholesterol is present between fatty acid molecules and prevents them from sticking to each other.
Therefore, the correct option is C. increasing the number of cholesterol molecules.
