Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.

Answer:
In the electromagnetic spectrum, the visible spectrum is the part, which is perceptible to the human eye. The electromagnetic spectrum in this array of wavelengths is known as simply light or the visible light. A general human eye will react towards the wavelengths in the range between 380 to 740 nm. A human eye sees the sky as blue that comes in the wavelength 490 nm because of the scattering of the visible light by the particles in the atmosphere. This concludes that 490 nm is the sole wavelength, which is reaching the eye.
Hi there!
Meiosis is a type of reproduction where two divisions occur. It is when gametes, sex cells, divide. In prophase of meiosis, it is similar to that of mitosis, as in the spindle fibers develop as well as centrioles. First, homologous (pairs) of chromosomes line up in the center of the cell. Next, spindle fibers pull the pairs apart, leaving one chromosome of each pair on each side. Then, the nuclear material divides as the spindle fibers and centrioles go away. Lastly, the cytoplasm divides, leaving two cells. Meiosis two starts out with prophase again. In prophase, the DNA condenses and forms short chromosomes as well as spindle fibers and centrioles developing. Next, the chromosomes (there is only one chromosome, made up of two sister chromatids) line up in the center of the cell. Next, the spindle fibers pull the chromosomes apart, pulling one chromatid to each side of the cell. Then, the nuclear material divides and the spindle fibers and centrioles disappear. Lastly, the cytoplasm divides, leaving four cell in total.
Hope this helps!! :)

B is the correct answer here.
The hexose (glucose) is the end product of the light-independent reactions of photosynthesis.
I hope that you find it useful.
