I believe that the answer is B. a fertilized egg splits in two but I could be wrong
The correct answer is air pollution
Through suppression of the aconitase enzyme in the tricarboxylic acid cycle, aconitase, fluoroacetate is extremely hazardous to humans and other mammals.
'Lethal synthesis' of an isomer of fluor citrate is the cause. fluoroacetate is present in many different plant species, and ruminant animals can die from ingesting them consists of aconitase.
With the chemical formula FCH 2 CO 2 Na, sodium fluoroacetate is an organofluoride. The taste of this colorless salt, which is utilized as a metabolic toxin, is comparable to that of sodium chloride. Potassium and sodium salts are both derived from fluor acetic acid. In 1942, a report on the efficiency of sodium fluoroacetate as a rodenticide was published.

Answer:
The options are
tapping the base of the pipette on the table
using subtraction to determine the volume dispensed
making sure that you read the volume with the liquid inside the pipette at eye level
reading only the final volume of liquid after dispensing
ensuring that air bubbles are not in the column of liquid inside the pipette
The answer is
using subtraction to determine the volume dispensed
making sure that you read the volume with the liquid inside the pipette at eye level
ensuring that air bubbles are not in the column of liquid inside the pipette.
Explanation:
A pipette is an instrument used in the laboratory for transporting and movement of liquid substances for various experiments. It is usually graduated to ensure accurate measurements of the liquid substance.
To ensure accurate reading of volume from a graduated pipette, precautions listed should be taken:
Using subtraction to determine the volume dispensed
Making sure that you read the volume with the liquid inside the pipette at eye level
Ensuring that air bubbles are not in the column of liquid inside the pipette.
As the left ventricle contracts, oxygenated blood leaves the heart through the aortic valve, into the aorta. The blood to lower limb flows through descending aorta, which continues down to Left Common Femoral Artery, which continues down to Left Superficial Femoral Artery, which continues down to Left Popliteal Artery. The Left Popliteal Artery gives 2 divisions.
1. Left Tibioperoneal Artery (which continues down to the Left Posterior Tibial Artery which supplies back of the foot.)
2. Left Anterior Tibial Artery (which continues down to Left Dorsalis Pedis Artery which continues down to <em>Left First Dorsal Metatarsal Artery</em> which supplies the big toe/first digit of foot.)
