Some bacterial cells live in very cold environments (such as the arctic ocean), but they still require membrane fluidity like th

eir cousins from more tropical climates. How would the membrane structure of a bacterial cell from a cold climate be different from the membrane structure of a bacterial cell from a very warm climate? Choose one:

Answer and explanation;

-Arctic microbes would have membranes with more unsaturated fatty acids; increasing the unsaturated fatty acid ratio would make it harder for the fatty acids to pack together. This will keep the membrane fluid at lower temperatures, which will benefit organisms that live in very cold climates.

-Microorganisms are adapted for optimum functioning in their normal physiological environments. Any extreme change in environmental conditions from the optimum inflicts a stress on an organism. For this reason they must accommodate a variety of changing conditions and stresses in their environment in order to survive and multiply.

The genes for miniature wings (m) and garnet eyes (g) are approximately 8 map units apart on chromosome 1 in Drosophila. Phenoty
Anestetic [448]

The following phenotypic classes reflect offspring that were generated as a result of a crossover event

  • wild type
  • miniature wings
  • garnet eyes

Explanation:

When the miniature wings and garnet eyes links up with the 8 map unit that are present between them. After that the presence of two recombinant classes must complement together and make 8% of total i.e. they contribute 4% each. together the parental classes make up to 92% by contributing 46% one.

This can be understood through a phenotypic ratio calculation, which can be expected from it.

wild type: 4% x 800 = 32

miniature wings: 46% x 800 = 368

garnet eyes: 46% x 800 = 368

miniature wings, garnet eyes: 4% x 800 = 368

A. it makes up the outer layer of the brain 
B. it's composed of an axon. 
C. it transmits nerve signals from one area of the CNS to another. 
<span>D. it's composed of dendrites

The correct answers are A and D

The gray matter of the brain is made out of nerve cell bodies, dendrites, and unmyelinated axons. The outer layer of the brain's cortex is made out of the gray matter and the inner layers are made out of white matter.
The white matter is made out of </span>myelinated axons that transmit nerve signals throughout the nervous system. The white matter is white because the myelin that surrounds the axons is white.
