Answer:
The correct answer is option C. the movement of water from the central vacuoles of the cells into the solution.
Explanation:
In the given question onion cell was initially in 1% NaCl solution later student increase the concentration of the NaCl in the solution which makes the solution hypertonic.
A hypertonic cell is a solution with less water or more solute. Increasing salt concentration makes solute concentration high than inside the cell. Cell shrink in this case due to the osmosis or water movement from the high concentration region of water to the low concentration of water region.

write any two method for identification of fossils?
Answers
Fossils of animals are classified, as are living specimens, by observing the body structures and functions. While there are a few unique challenges in classifying fossils, the basic scheme of organization is the same. Going one step at a time can make fossil identification possible for anyone.
Traces of the dead bodies present on the sedimentary rocks are fossils identification parts. By the physical appearance as well we can see the fossils and the types.
What are the ways by which fossils form ?Molds and the casts are the ways by through the fossils are formed out.
Something becomes fossil then it is mineralized or later becomes is made of the minerals. This is usually meaning an increase in the weight. A fossil bone is just heavier than the normal bone that is noticeably so. So if object is heavy then it just might be the fossil. Sediment might fill mould and later form cast fossil.
Have an eye that looks for the detail Look for the regular lines along with the marks or the patterns on the pebbles just like ridges or the growth lines in the shell. Looking for the tiny pieces that are among the beach pebbles and not only the big stones. Often the crinoid stems or the belemnites can also be small as the little fingernail.

describe the main difference between a bright field, compound light microscope and a dissecting microscope
Answers
Answer:
Please find the main difference in details between these two microscopes below
Explanation:
Compound microscopes and dissecting microscopes are two types of light microscopes. This means that both types of microscope uses light as a source of view. However, they are used for different purposes despite this similarity.
- The compound microscope is used to view the internal features of a small specimen by looking through it. This is due to the high magnifying power of its objective lenses (40x - 1000x).
- On the other hand, dissecting microscopes are used only to view the surface of a large specimen owing to its low magnifying power. It can be used to view a three dimensional object.

Glaciers bring quantities of minerals that choke plant life as the water runs off melting ice.
Glaciers has no effect on plant life other than helping distribute necessary water.
Glacial flooding is destructive to plant life as silt builds in rivers.
Answers
Answer:
Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.
Explanation:
Glaciers are natural reservoirs of water and minerals that may persist to dry conditions during the summer season. Ice melting provides water and minerals during the warm season, which is therefore critical for plants living in dry summer environments. Moreover, it is well-known that the 'melt-water' (i.e., water released by the melting of glacial ice) also affects downstream stream water temperatures, creating a microhabitat that may be beneficial to the life of plant species.

An Allele which express itself during gamete formation is termed as:
Answers
Answer:
the ability of one allele to express its phenotype at the expense of an alternate allele; the major form of interaction between alleles; generally the dominant allele will make a gene product that the recessive can not; therefore the dominant allele will express itself whenever it is present.
Explanation:
Answer:
Alleles occur in pairs. Out of two alleles, only one allele expresses itself in the hybrid and prevents the expression of the other allele. The allele which expresses itself in the hybrid is called dominant allele and the other allele which is unable to express in the hybrid is termed as recessive allele.
