Scientists rely on concepts when researching crop production and medicine. biology physics geology astronomy

A). Biology.

Explanation:

As per the question, scientists depend on 'biology' concepts at the time of researching on medicine and the crop production as the biological concepts assist the researchers to test the validity of their experiments and their results. The medicinal researches as well as agriculture both are either directly or indirectly associated to the biological systems or its derivatives. Thus, 'biotechnology' is used for modification and advancement in their respective fields and hence, option A is the correct answer.

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
