The visible light microspectrophotometer is a convenient tool with which to compare the color of fibers because:
a. very small samples can be compared
b. fibers can be studied right on a microscope slide
c. fibers are not destroyed
d. all of the above

d. All of the above

Explanation:

A microspectrophotometer is an instrument used to measure the spectra of microscopic samples, thus,  it is used for color comparison between samples.

It  is able to measure very small samples , as small as  1 x 1 micrometers. That is, smaller than the diameter of a human hair, therefore it is suitable for the analysis of many other types of fibers that can be mounted on  microscope slides.

The microspectrophotometer allows to acquire extremely small sample spectra without destroying them at all

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.

explanation:

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
