6. which of the following does not have an endosymbiotic origin? a. ribosome b. mitochondria c. chloroplast d. nuclear envelope e. all of the above have endosymbiotic origins
Answers
The correct answer is d. nuclear envelope. The nuclear envelope does not have an endosymbiotic origin.
The nuclear envelope does not have an endosymbiotic origin. It is formed from the invagination of the cell membrane during the process of nuclear formation, which is distinct from endosymbiosis. On the other hand, the other options (a. ribosome, b. mitochondria, c. chloroplast) do have an endosymbiotic origin. Mitochondria and chloroplasts are believed to have originated from ancient endosymbiotic events where free-living bacteria were engulfed by ancestral eukaryotic cells, eventually leading to a symbiotic relationship. Ribosomes, while not organelles, have an endosymbiotic origin as well, as they are thought to have evolved from ancient free-living bacteria that were engulfed by early cells.In conclusion, while the ribosome, mitochondria, and chloroplast have endosymbiotic origins, the nuclear envelope does not.

Answers
The hypothesis of Alexander Fleming was that Penicillium produced a chemical called penicillin that affects the growth of bacteria. He tested this hypothesis in the following way:To test his hypothesis, Alexander Fleming took a culture of staphylococci bacteria and grew it in a Petri dish.
Once the bacteria had grown, he applied a bit of mold from a contaminated laboratory dish to the dish with the bacteria. After a while, he found that the bacteria in the area surrounding the mold was dead and did not grow again. However, the bacteria in other areas of the dish where there was no mold continued to grow as usual. After many trials, he concluded that the mold had released a substance that stopped the growth of the bacteria and named it penicillin.
Thus, Alexander Fleming tested his hypothesis by growing staphylococci bacteria in a Petri dish and applying mold from a contaminated laboratory dish to the dish with the bacteria. The bacteria in the area surrounding the mold died while the bacteria in other areas continued to grow.

Answers
The glomerulus is a unique high-pressure capillary bed in the kidneys. This filtration bed is considered high pressure due to the type of vessels feeding and draining it. The afferent arteriole feeding the glomerulus is larger in diameter than the efferent arteriole draining the bed.
This anatomical characteristic makes the blood entering the bed to be under high pressure and leaves the bed under lower pressure. This pressure differential between the two arterioles forces fluids and solutes through the walls of the capillaries and into the urinary tubules for further filtration. Therefore, the larger diameter of the afferent arteriole provides a higher volume of blood under higher pressure to the glomerulus, increasing the efficiency of the filtration. The smaller diameter of the efferent arteriole slows the blood flow, increasing the pressure inside the capillaries and maintaining the high pressure in the bed. This anatomical feature provides a unique and efficient filtration mechanism to the kidneys.

Body Surface Area -adapted from the Redlarski’s paper (link)
Body surface area (BSA) plays a key role in several medical fields, including cancer chemother-
apy, transplantology, burn treatment and toxicology. BSA is often a major factor in the
determination of the course of treatment and drug dosage. A series of formulae to simplify
the process have been developed. Because easy-to-identify, yet general, body coefficient re-
sults of those formulae vary considerably, the question arises as to whether the choice of a
particular formula is valid and safe for patients. These empirical formulae are derived by
observing/fitting the experimental data and do not have a rigid model or reason explain-
ing their validity. In this problem, you will build a physics model to create your own BSA
equation other than using an empircal formula.
(a) Use a cylinder of height H and radius r as a approximation of the shape of a human.
Calculate the human’s body surface area(BSA), volume(V), and mass(M) in terms of
r and H. You may assume the density of human is 1000 kg/m3.
(b) Rewrite the surface area in in terms of height and mass.
(c) According to the equation you derived above, what is your body surface area? Is it the
same as the result calculated by using the empirical fomulae: BSA = √M H/C with
BSA in m2, M in kg, H in cm, and C=60 is a constant in this paper? If not, what is the percentage differences?
Note: percentage difference for two values E1 and E2 are |E1−E2|
(E1+E2)/2 ×100%.
(d) Considering the formula BSA = √MH/C with fixed H, plot a graph with BSA on
the y-axis and M on the x-axis. Explain what the trend/curve means.
(e) Considering the formula BSA = √MH/C with fixed BSA, plot a graph with H on
the y-axis and M on the x-axis. Explain what the trend/curve means.
(e) Considering the formula BSA = √MH/C with fixed BSA, plot a graph with H on

Answers
a)Using a cylinder of height H and radius r as an approximation of the shape of a human, the surface area, volume, and mass are calculated in terms of r and H as follows:
Surface area (S) of a cylinder is 2πrh + 2πr², where h is the height, and r is the radius of the cylinder. In this case, the height of the cylinder is equivalent to the height of the human body. Hence;S = 2πrH + 2πr²Mass (M) of a cylinder is given by M = ρV, where ρ is the density of the cylinder, and V is the volume. Hence, the mass of a cylinder in terms of its radius and height isM = πr²HρVolume (V) of a cylinder is given by V = πr²H. Hence, the volume of a cylinder in terms of its radius and height isV = πr²H(b)The body surface area (BSA) of a human can be rewritten in terms of the height (H) and mass (M) as follows:
BSA = √(M/H C)We can rewrite it as H = M/ (BSA² C)Thus, H can be expressed as a function of M and BSA asH = M/(BSA² C)(c)If r = 0.15 m and H = 1.70 m, then using the equation, S = 2πrH + 2πr², the body surface area is given as:
S = 2π (0.15)(1.70) + 2π (0.15)² = 1.77 m²Using the empirical formula, BSA = √(MH/C) with M = 60 kg and H = 170 cm, we get BSA = 1.85 m²The percentage difference is given by;|E1 − E2| / (E1 + E2) / 2 × 100%where E1 = 1.77 m² and E2 = 1.85 m²Thus;|1.77 – 1.85| / (1.77 + 1.85) / 2 × 100% = 4.2%(d)Considering the formula BSA = √(MH/C) with fixed H, a graph with BSA on the y-axis and M on the x-axis can be plotted.The trend shows a non-linear increase in BSA as the mass increases.
(e)Considering the formula BSA = √(MH/C) with fixed BSA, a graph with H on the y-axis and M on the x-axis can be plotted.The trend shows a linear increase in height as the mass increases.

The statement "It releases hormones, all of which are lipids, directly into the bloodstream" is false because not all hormones are lipids. In fact, there are several types of hormones, including peptide hormones, steroid hormones, and amino acid derivatives.
The statement "It releases hormones, all of which are lipids, directly into the bloodstream" is false. This is the answer to the question which of the following statements about the endocrine system is false.The endocrine system is a complex network of glands and organs that secretes hormones. Hormones are molecules that act as chemical messengers and are released by the endocrine glands into the bloodstream, where they travel to distant target cells to exert their effects.The endocrine system is regulated by negative feedback mechanisms, meaning that the production and secretion of hormones are controlled by the levels of hormones in the blood. This is to ensure that the hormone levels remain within a normal range, which is essential for maintaining homeostasis.The endocrine system affects only cells with appropriate receptors, which are proteins on the surface of target cells that recognize and bind to specific hormones. This ensures that the hormones act only on the cells that need them.The endocrine system releases secretions, which are hormones, directly into the bloodstream, not body fluids. This allows the hormones to travel throughout the body and reach their target cells.The statement "It releases hormones, all of which are lipids, directly into the bloodstream" is false because not all hormones are lipids. In fact, there are several types of hormones, including peptide hormones, steroid hormones, and amino acid derivatives.
