Biodiversity is the variety of plants, animals and ecosystems in the world, it is a measure of our planet's health. Overexploitation of species, habitat destruction, and the introduction of invasive species are threatening Earth's biodiversity.
Students are investigating the distribution of dandelions using quadrats. The students could during their investigation is they can do the pH test and the effect if it is happening or not.
<h3>What is pH?</h3>
pH is the measurement of the acidity or alkalinity of a substance. PH is a scale that marks from 0 to 12. The substance above 7 is acidic and the substance that is basic comes after 7. 7 is the number for neutral, which is pure water. The pH test is very easy to conduct.
To be sure that pH of the soil will not affect the distribution of dandelions. They first test the pH of the soil.

Answer:
<h3>
Hey!</h3>
¨Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. ¨
<h3>Good luck! </h3><h3>Follow me plz, thx :)</h3>
The correct answer is option D, that is, C30H52O26.
The majority of macromolecules are formed as single building blocks or subunits, known as monomers. The monomers attach to each other through covalent bonds to produce bigger molecules called polymers. In performing so, the monomers discharge molecules of water as byproducts. This kind of reaction is called dehydration synthesis.
In a dehydration synthesis reaction among the two un-ionized monomers, like monosaccharide sugars, the hydrogen of one monomer merges with the hydroxyl group of another monomer, discharging a water molecule in the process.
The withdrawal of a hydrogen from one monomer and the withdrawal of a hydroxyl from the other monomer permits the monomers to share electrons and produce a covalent bond. Therefore, the monomers, which are combined together are being dehydrated to permit for the production of a larger molecule.
