Answer:
The correct answer will be option-D.
Explanation:
Fungi forms symbiotic or mutual relationship with higher plants known as mycorrhizae.
These mycorrhizae could be present on the tree parts like stem which form the ectomycorrhizae and some live inside the plant parts like in the roots and known as endo-mycorrhizae.
The fungi provide useful nutrient like they absorb phosphorus from the soil and provide it to the plants and in return plant give shelter to these fungi.
Thus, option-D is the correct answer.
The answer is that the equatorial regions receive sun rays closest to the vertical (direct rays) because of their position relative to the equator where the tilting of the earth only mildly affects the climate. The climate along the equator changes very little through out the year and has summer like conditions for most of the year.
However the other regions may receive direct sun rays but for far more limited periods. In the months of July and August (summer months), the northern hemisphere is tilted towards the sun and receives the most direct rays. The opposite occurs in December and January when it is tilted away from the sun and thus winter sets in, whereas the southern hemisphere is at this time tilted toward the sun and receives the most direct sun rays.
DNA is a negatively-charged molecule. Also cell membranes are negatively charged. The problem would be how to push this charges together? I<span>f you put some CaCl2 into the mixture, the CaCl2 will "split" giving 2Cl- and Ca2+. This last ion will be attracted by the negatively charged DNA and will "cover" it, hiding its negative charge. Hope this answers the question.</span>
Biologists do not fully understand DNA because there are constant changes and new discoveries developing.
I think the answer is F<span>ossil shells on top of mountains</span>
