<span>A method of deducing the correct species
assignment of a living thing is known as dichotomous key, which is also called
identification key. It works by requiring a user to choose two alternatives at
each step and the choice of one alternatives give the name of the organism or
direct further down in the key. However, a common error in using dichotomous
key is the assumption that the correct name or identification of the organism
is even included in the set of key. Therefore, this method alone is not reliable
to identify specific species.</span>
Answer:
D. Agronomist
Explanation:
Agronomists are professionals that study how to make soils more productive (in terms of food) around the world. Soil pH is an index that calculates the acidity/alkalinity of the soil, which is indicated on a 14-point scale (pH equal to 7 = neutral; pH below 7 = acidic, pH higher than 7 = alkaline). In this regard, it is well known that the pH of the soils drastically affects plant development, and thereby a proper soil pH is fundamental to ensure optimal plant growth (required for nutrient intake). For this purpose, agronomists are in charge of studying and researching the pH of the soils in order to increase crop yields. Nowadays, the pH of the soils can be easily measured by digital soil pH pocket testers that utilize a pH electrode in order to calculate the pH value.
Answer:
c
Explanation:
Im pretty sure, so sorry if I'm wrong though.
Answer: .OH, O2-, H2O2
Explanation:
Reactive oxygen species (ROS) are chemically reactive and unstable species containing oxygen. ROS are formed when oxygen is partially reduced, thus they are all radicals with very high reactivity, attacking membrane proteins such as ion channels etc
Examples include peroxides (H2O2), superoxide (O2-), hydroxyl radical (.OH)
