The five earth's spheres are biosphere, hydrosphere, atmosphere, geosphere and lithosphere.
An organism like polar bear might react with each of the sphere in the following way: The bear has its habitat on the land (lithosphere), he eat grasses and other small animals found in the biosphere. It drinks water, which is part of the hydrosphere. It breaths in oxygen and breath out carbon dioxide into the atmosphere. Its wastes is a source of food to decomposers, ( in the geosphere) which breaks it down for plants' use
The gametes that are produced contain half the actual number of chromosomes that are found in the organism.
Option C
<h3><u>
Explanation:</u></h3>
The gametes are the units of sexual reproduction. These gametes are formed from the gamete mother cell by the process of meiosis. Meiosis actually convert a diploid cell into a haploid cell by reducing the chromosome number to half. So the genetic information of the gamete is also half to that of the other cells of that organism.
When two gametes fuse, they actually complete the full set of chromosomes and form a new organism which contains the characters according to the dominant and recessive basis. So offsprings are not completely similar to any of the parents.

The visible light spectrum. Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. ... When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer.
