Summary Introduction

Introduction:

Respiratory system consists of organs that take part in the process of respiration. Respiration is a process, in which food is broken down into simpler components releasing energy. Respiratory system consists of organs that participate in the exchange of gases.

Answer to Problem 1TYU

Correct answer:

The tracheal system of an insect is not associated with a blood supply. Therefore, option (C) is correct.

Explanation of Solution

Reasons for the correct statement:

Tracheal system of an insect consists of spiracles, which is a series of holes or openings. These spiracles are responsible for respiration in insects. Spiracles do not have any blood supply.

Option (C) is given as “the tracheal system of an insect”.

As “the tracheal system is not associated with blood supply”, it is the right answer.

Hence, option (C) is correct.

Reasons for the incorrect statements:

Option (A) is given as “the lungs of a vertebrate”.

The lungs of a vertebrate are connected with blood capillaries. These capillaries bring deoxygenated blood to the lungs and carry away oxygenated blood. So, it is a wrong answer.

Option (B) is given as “the gills of a fish”.

Gills of a fish have gill lamellae and it contains blood within itself. The blood in gill lamellae flows in the opposite direction of the water. So, it is a wrong answer.

Option (D) is given as “the skin of an earthworm”.

Moist skin of earthworm is responsible for respiration and it is associated with blood vessels. So, it is a wrong answer.

Hence, options (A), (B), and (D) are incorrect.

Conclusion

Respiratory systems are those systems, which perform the basic function of respiration. They are somehow related to blood supply either directly or indirectly, but the tracheal system of insects is not associated with blood supply.

. Consider a base substitution mutation that occurred in a DNA sequence that resulted in a change in the encoded protein from the amino acid glutamic acid to aspartic acid. Normally the glutamic acid amino acid is located on the outside of the soluble protein but not near an active site. O-H¨ A. What type of mutation occurred? O-H B. What 2 types of chemical bonds are found in the R-groups of each amino acid? The R groups are shaded. CH2 CH2 CH2 H2N-C-COOH H2N-C-COOH 1 H Glutamic acid H Aspartic acid C. What 2 types of bonds could each R-group of each of these amino acids form with other molecules? D. Consider the chemical properties of the two amino acids and the location of the amino acid in the protein. Explain what effect this mutation will have on this protein's function and why.
engineered constructs that consist of hollow fibers are acting as synthetic capillaries, around which cells have been loaded. The cellular space around a single fiber can be modeled as if it were a Krogh tissue cylinder. Each fiber has an outside “capillary” radius of 100 µm and the “tissue” radius can be taken as 200 µm. The following values apply to the device:R0 = 20 µM/secaO2 = 1.35 µM/mmHgDO2,T = 1.67 x 10-5 cm2/secPO2,m = 4 x 10-3 cm/secInstead of blood inside the fibers, the oxygen transport and tissue consumption are being investigated by usingan aqueous solution saturated with pure oxygen. As a result, there is no mass transfer resistance in the synthetic“capillary”, only that due to the membrane itself. Rather than accounting for pO2 variations along the length ofthe fiber, use an average value in the “capillary” of 130 mmHg.Is the tissue fully oxygenated?

In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5.
