Answer:
concentration of calcium ion mEq/L = 1.21 x 2 = 2.42mEq/L
Explanation:
given
- concentration of calcium ion in blood = 1.21 mmol/L
- Concentration in mEq/L = Concentration in mmol/L x valence of the ion
- The valence electron is the number of electron present in the outermost shell. Calcium belongs to the group2 elements also known as the alkaline earth metal, and their valence electron is 2.
- Hence, concentration of calcium ion mEq/L = 1.21 x 2 = 2.42mEq/L
where mEq/L = milliequivalent per liter
Answer:
A lipid is any of various organic compounds that are insoluble in water. They include fats, waxes, oils, hormones, and certain components of membranes and function as energy-storage molecules and chemical messengers.
Answer: Well, populations never evolved than one human might have gone extinct due to many different viruses and sicknesses but other animals might not be extinct.

The correct answer will be option-D
Explanation:
Arid areas are the regions of the world which can be marked with the lack of water conditions, high light intensity and very low rainfall.
Water is one of the primary requirement of the plant without which no plant can survive but the adaptability to the environment allows the existence of the life on earth.
There are known species of plants which are adaptive to such arid conditions.
If a farmer is interested in growing plants in such arid conditions hen he should select the plants which could better be adapted to survive in the arid conditions either by avoiding arid condition like storing water, low transpiration, extensive root system and many others.
Thus, Option-D is the correct answer.
