Answer:
It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. Plants need to cool themselves for several reasons. ... Transpiration is an evaporative cooling system that brings down the temperature of plants, but since it leads to water loss, it must be accurately regulated.
Explanation:
Answer: Option C) The arrangement of atoms allows precise hydrogen bonding.
Explanation:
The individual hydrogen bonds between the base pairs confer stability to double helix of DNA.
The bases atoms take SPECIFIC POSITIONS or better still ARRANGEMENT, with Guanine pairing with Cytosine base atoms by three hydrogen bonds, while Adenine pair Thymine base atoms by two hydrogen bonds.
So, the arrangement of base atoms allows precise hydrogen bonding and hence STABILITY of DNA double helix.
<span>Lateral roots that extend out are called called tap roots.
The first root which develops from a radicle and becomes dominant is called a taproot. Roots that develop from other roots are generally termed as lateral roots; >Roots that arise from other plant organs rather than the root, are called adventitious roots.</span>
You don't need to push the wheelbarrow down the beach. Instead, fill it up with sand.
