Question
Chapter 10.5, Problem 2C
Summary Introduction
To determine: The way by which meiosis and fertilization maintain the normal chromosome number when a sexually reproducing organism like protists is haploid throughout most of its life cycle.
Introduction: In the process of cell division, the chromatin present in the nucleus shrinks and forms a thread like structure called the chromosomes. Cells divide either by mitosis or meiosis processes. A protist is a eukaryotic organism that is distinct from animal, plant or

- 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?arrow_forwardMolecular Biology Please help with question. thank you You are studying the expression of the lac operon.

A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane.
