In addition to the transmission electron microscope (TEM), there is another type of electron microscope that is frequently used for specific purposes when studying cells and tissues, and even whole organisms. This microscope is called a scanning electron microscope (SEM). Use your lab manual, its support resources, and/or the Internet to investigate the use of scanning electron microscopy for biological applications. After gathering this information, please answer the following question. When would it be appropriate to use the SEM rather than the TEM
Answer:
The basic difference between SEM and TEM is that TEM generates an image with the assistance of radiation that goes through the specimen, while the images generated by the SEM take place with the assistance of electrons getting released from the surface of the specimen.
SEM is primarily used to examine the composition of the surface, with the help of SEM one can study the microbes present in the ecological niche like in the lining of the gut and human skin. Due to its great depth, it is considered the electron microscope analog of a stereo light microscope. It helps in providing complete images of the cells present on the surface, which are not easy to get with the help of TEM. Due to its enhanced functionality, it can also be used for size determination and particle counting, and also for process control.

Please explain how shade-adapted plants tend to differ from sun-adapted plants, using the terms: specific leaf area, dark respiration, root mass fraction, leaf lifespan.
Answer:
Thickness and number of chlorophyll.
Explanation:
Shade-adapted plants differ from sun-adapted plants due to many characteristics such as thickness and number of chlorophyll. Sun leaves are more in thickness than shade leaves because they develop longer palisade cells. Shade leaves generally have more chlorophyll as compared to sun-adapted plants. Specific leaf area and root mass fraction of Shade-adapted plants are higher as compared sun-adapted plants due to large number of chlorophyll to harvest more sunlight for photosynthesis. Dark respiration is higher in sun-adapted plants when there is darkness as compared to shade-adapted plants which produce food in no direct sunlight.

Hyperglycemia (elevated blood sugar levels), such as would happen in diabetics, can damage the glomeruli.
a. True
b. False
Answer:
True
Explanation:
Hyperglycemia which means high Glucose level in the blood as a result of lack of insulin can damage the glomeruli. This interfere with the function of the glomeruli. Normally glomeruli fiters blood and remove nutrients to form urine but hyperglycemia will affect it's negatively and will make protein to leak from the blood into the urine. This can also lead to glomeruli called glomerulosclerosis.
What is the rapid change in a membrane's potential caused by the depolarization of a neuron?
Answer:
During depolarization, the membrane potential rapidly shifts from negative to positive. As the sodium ions rush back into the cell, they add positive charge to the cell interior, and change the membrane potential from negative to positive.

• Write the biofuel and biogas chemical formulas. Explain why biofuel and biogas are still considered energy-dense molecules. Compare the chemical makeup of each component to carbon dioxide, which is produced when glucose is completely oxidised.
Answer:
diesel fuel is C12H23 whereas Methane is CH4.
Explanation:
The chemical formula for common diesel fuel is C12H23 while o the other hand, the formal of biogas such as Methane which is CH4. Both are organic compounds due to the presence of hydrogen and carbon. Biofuel and biogas are still considered energy-dense molecules because they have more mass and produced large amount of energy from it. The main difference between Carbondioxide gas and biofuel is that there is no hydrogen present in the formula of carbondioxide gas.
Rheumatoid arthritis is commonly associated with the presence of rheumatoid factor autoantibodies in the bloodstream. This indicates that rheumatoid arthritis is likely to be a. an infective process. b. caused by bacterial infection. c. an autoimmune process. d. because of an enzymatic defect.
Answer:
The correct answer is - c. an autoimmune process
Explanation:
Rheumatoid arthritis is a disease or condition that affects the joints mainly by swollen, and painful joints. It is an autoimmune disease as the person's own immune system attacks the body.
The presence of rheumatoid factor autoantibodies states that it is an autoimmune process. There are other autoantibodies also associated with this type of arthritis that are rheumatoid factors (RF), anti‐keratin antibodies (AKA), anti‐filaggrin antibodies (AFA), and anti‐perinuclear factor (APF).
The antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline, chloramphenicol disk. Interpret the result.
Answer:
See Explanation
Explanation:
We define antibiotic susceptibility testing as an evaluation of the ability of antibiotics to inhibit bacterial growth. This test is necessary because certain bacteria may have developed resistance to certain antibiotics.
Hence, if the antibiotic susceptibility testing result of Staphylococcus aureus showed absence of growth on the zones of penicillin, ampicillin, tetracycline and chloramphenicol disk, then it implies that these antibiotics are all largely effective against Staphylococcus aureus and could be used for treatment of Staphylococcus aureus infection.
Alleles are described as ____________________. homologous chromosomes homologous chromosomes alternate versions of a gene alternate versions of a gene alternate phenotypes alternate phenotypes environmental factors that affect gene expression
Answer:
The correct answer is - alternate versions of a gene.
Explanation:
In a cell, if there are two copies of each chromosome, these are called homologous chromosomes, one come from the father and the other comes from the mother, which helps in promoting the variety and stability of a species.
Different or alternate versions of genes are possible that can result in two phenotypes for the same trait, these alternate versions called alleles. Alleles can be dominant and recessive.

what impact are these practices expected to have on soil pH and why?
Inherent factors that affect soil pH include climate, mineral content, and soil texture. Natural soil pH reflects the combined effects of the soil-forming factors (parent material, time, relief or topography, climate, and organisms). The pH of newly formed soils is determined by the minerals in the parent material.

Answer:
Lipase is an enzyme that helps in the catalysis of the hydrolysis of fats and other carboxylic acid esters. Lipases act/functions according to the substrate molecule constituent and how similar the chemical linkages are.
Lipase action on fats and carboxylic esters which are different molecules but with similar chemical constituents and bonds explains enzyme action only some unique bonds in a compound.

All of these children (including the fraternal twin sisters in the front row)
are the biological children of the two parents in the middle of the picture.
Based on everything that you have learned in this unit, explain why these
brothers and sisters do not look exactly alike. Include the processes of cell
division and the rules of genetics in your answer.
Answer:
Explanation:
Because in the fetus stages of fraternal twins two different eggs get fertilized. Therefore, genetics won't be the same for both twins. But if they were identical twins the fertilized egg was to divide and the two zygotes would've carried the same genetics of each other.
Neosporin is an antibacterial ointment used in the prevention and fighting of infection and in speeding the healing of wounds. Determine if this would be considered part of the first line of defense and which barrier category it would belong to. Explain your answers.
Answer:
Explanation:
The use of ointment for bacterial treatment does not fall into the first line of defence.
The first line of defence are physical (skin,tears, mucus) and chemical barriers( white blood cells also called neutrophils) which are prepared to defend the body against infection. The skin which is one of the first line of defence is a barrier that prevents entry of microorganisms the body. When the first mechanism is not effective especially for pathogens then the second mechanism is activated to get rid of the microorganism.
The use of ointment does not belong to any barrier or defence mechanism this is because it is not a natural way of getting rid of microorganisms within the body system.
