The plant pigments extracted in the virtual lab that were water soluble were determined to be chlorophyll.
<h3>What is Chlorophyll?</h3>
This is a green pigment used by plants to produce food through the process of photosynthesis.
The pigment is used to convert light energy into chemical energy thereby making it the most appropriate choice.

Answer:
D. frictional, structural, and cyclical unemploment.
Explanation:
Types of Unemployment
There are three basic types of unemployment which are the cyclical, frictional, and structural.
Cyclical Unemployment
Is due to the highs and lows of the economy, as in cycles e.g in times of recession, the job lost is know as cyclical unemployment.
Frictional Unemployment
It results from the actual turnover in the labor market and the time taken to get a new job. E.g. when a worker change his/her job, it requires time to get a name job and learn more of the job in details for him/her to be called up for interview and get hired. This process is termed frictionally unemployed.
Structural Unemployment
Originates from a lack for demand for a specific class of worker due to the worker lacking the appropriate skills needed by the employee as this can cause the worker to lose the job. Another example is sourcing for a reduced cost of labour abroad.

Answer:
Phospholipids are able to form cell membranes because the phosphate group head is hydrophilic (water-loving) while the fatty acid tails are hydrophobic (water-hating). They automatically arrange themselves in a certain pattern in water because of these properties, and form cell membranes.
Explanation:
Answer:
genomic imprinting
Explanation:
Genomic imprinting is a mechanism for regulating gene expression that allows expression of only one of the parental alleles, although both alleles are functional. Unlike most genes in which expression is biallelic, genes that are subjected to this mechanism (imprinted genes) have monoalelic expression; By definition, in an imprinted loci, only one allele is active (maternal or paternal), and the inactive is epigenetically marked by histonic modification and / or methylation of cytosines.
Genomic imprinting can cause some disturbances, among them Prader-Willi syndrome, which is a genetic disorder that involves a partial deletion of chromosome 15q on the paternal chromosome.
