) Imagine that you are studying a newly discovered bacteria from a hot spring in Yellowstone National Park. You examine the nitr

ogenous bases of this organism, and find that 10% of the nitrogenous bases in its DNA are adenine. What percentage of nucleotides are cytosine

Answer:

Cytosine- 40%

Explanation:

DNA is the genetic material in virtually all living organisms. It is a molecule made up of long chains of nucleotides, which are its building block. Four types of nucleotides make up the DNA molecule viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).

According to Erwin Chargaff in his rule regarding DNA composition, he stated that in a DNA molecule, the amount of adenine must equal thymine while that of guanine must equal cytosine. In a nutshell, the total of all the base pair must equally be 100% i.e. (A + T) + (G + C) = 100%.

In this case where a newly discovered bacteria from a hot spring in Yellowstone National Park was found to contain 10% of adenine in its DNA. Since Adenine is 10%, Thymine base must also be 10% in accordance to Chargaff's rule.

Hence, 10% + 10% + (G + C) = 100%.

20% + G + C = 100%

G + C = 100 - 20

G + C = 80%

Since, G and C must be equal, then G = C = 80% ÷ 2 = 40%. This means that the percentage of cytosine will be 40%.

I will try my best to answer your question

Shearing forces-rationale: friction, impaired circulation, localized pressure, and shearing forces are all risk factors of pressure ulcer development; trapeze use reduces shearing forces. shearing forces (opposing forces that cause layers of skin to move over each other, stretching and tearing capillaries and, eventually, resulting in necrosis) can occur as clients slide down in bed or are pulled up in bed. subcutaneous skin layers adhere to the sheets while deeper layers, muscle, and bone slide in the direction of movement. to reduce shearing forces, the nurse should instruct the client to use an overbed trapeze, place a draw sheet under the client to move him up in bed, and keep the head of the bed no higher than 30 degrees.client needs category: physiological integrityclient needs subcategory: basic care and comfortcognitive level: applicationreference: taylor, c., et al. fundamentals of nursing: the art and science of nursing care, 6th ed. philadelphia: lippincott williams & wilkins, 2008, p. 1196.

Facilitated diffusion- molecules helped by protein; move insoluble molecules

across plasma membrane

Passive diffusion- molecules move in and out freely from high to low concentration

Phagocytosis- cell engulfs microorganisms in cell "eating"

Active transport- molecules "pumped" in or out from low to high concentration

Passive diffusion- oxygen, carbon dioxide

Active transport- transports sodium, potassium

Pinocytosis- transports glucose, amino acids
