Answer: decreases

Explanation:

The surface area to the volume ratio will decrease as the volume of the cell increases or the cell gets larger. Therefore, if the volume of the cell increases beyond the certain limit the cell will not be able to imbibe nutrients as not enough material can pass through the cell membrane to accommodate the increase in volume of the cell.

Organization is one of the characteristics of life. Explain how your observations under the magnifying glass support this idea.
seraphim [82]

Answer:

All living things are made up of cells. Cells are building blocks of life. Cells are the simplest level of organization. The structure of multicellular organisms are made up of many parts that are required for survival of organisms. The level of organization in multicellular organisms includes: cells, tissues, organs and organ system. The organization is necessary for the body of the organisms to function properly as a characteristic feature of living being.

Magnifying glass is a convex lens that is fitted in a microscope can be used to magnify the image of object under observation. A magnifying glass in a microscope can be used to magnify minute cells and small living creatures. All cells aggregate to form tissues. It can be used to see the arrangement of cells in a tissue specimen and small organelles like chloroplast, mitochondria, nucleus and others.

Therefore, observations under the magnifying glass support  the idea of organization is one of the characteristics of life.

What advantage might chromosome banding patterns have in the analysis and diagnosis of chromosomal problems or abnormalities?
Shtirlitz [24]
<span> Chromosomal banding pattern is the pattern of colors formed when the chromosome is exposed to certain specific dyes.

These dyes do a color reaction with a special repetitive sequence of base pairs.

When the normal pattern is not obtained
there may be two reasons
1. Chromosomal injury
2. Chromosomal aberration.

In injury certain part is either deleted or shifted to somewhere else

in aberration chromosome is normal but its sequence is got changed.

So its certain that is has got great diagnostic value.
But it fails
in case of point mutation or certain others.

This banding pattern is also helpful in preliminary diagnosis of a suspect in any crime but most of the judiciaries do not assure of its results. </span>
