To determine: The reason for the increase in atrial pressure just to the right of C point in the Wigger’s diagram of cardiac output.
Introduction: The atrial pressure describes the average pressure in the arteries of an individual during one cardiac cycle.
To determine: The reason for the decrease in atrial pressure during the initial part of ventricular contraction and then increases.
Introduction: The flow of blood through the heart is governed by the same principle that governs the flow of liquids and gases. The blood flow proceeds from the regions of high pressure to the regions of low pressure.
To determine: The reason for the decrease in atrial pressure to the right of D point.
Introduction: The human heart is made of four chambers: left atrium, left ventricle, right atrium, and right ventricle. The main function of the heart is to pump blood throughout the body via the circulatory system.

- Which of the following statements about hydration is true? Absence of thirst is a reliable indication that an individual is adequately hydrated. All of these statements are true. Although a popular way to monitor hydration status, weighing yourself before and after intensive physical activity is not a reliable method to monitor hydration. Urine that is the color of apple juice indicates dehydration. I don't know yetarrow_forwardThree of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes.

- Genes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be. What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle? What classes would be least frequent if locus f is in the middle? What classes would be least frequent if locus w is in the middle?arrow_forward1. In the following illustration of a phospholipid... (Chemistry Primer and Video 2-2, 2-3 and 2-5) a.
