Cold and extremely down climate is experienced in these locations, this is due to the lack of exposure to the sun's rays. The North and South Pole of the earth are also responsible for many meteorological and astronomical occurrences that protects earth and its inhabitants from the harsh exposure to the sun's rays.
Phloem is the food conducting tissue that has a two-way flow.
Explanation:
Plants prepare food on their own and plants also have conductive cells that carry out transportation process. Plants are divided into two types based on their conductive system i.) vascular plants ii.) non vascular plants.
Vascular plants are those plants which have special conductive cells called phloem and xylem.
Xylem transports water from roots of the plants to other parts of plants and also provides mechanical support to plant. It is uni-directional.
Phloem is the food conducting tissue that transports food to plant and also have bi-directional movement.
Answer:
Physical Weathering
Explanation:
As per the given conditions in the question, the primary effect is <u>mechanical action</u> which is also known as a <u>physical weathering</u>. During mechanical action, a rock is disintegrated into the smaller pieces. In the given statement, <u>the root of tree would grow in the crack and try to develop a strong network to get nutrients necessary for tha tree growth</u>. Thus, the <u>root would exert a pressure</u> in the crack to make more space for its growth and development (root network). This is primarily a mechanical action and an example of physical weathering.

For the answer to the question above, I think that <span>Mendeleev's eka-aluminum is what we know today as <u><em>GALLIUM</em></u></span><u><em>.</em></u>
or the era of Mendeleev is <u><em>Aluminum</em></u> which is that <span>it would <u><em>be a soft metal with a low melting point.</em></u></span>
I hope my answer helped you. Have a nice day!
