I) Alleles is the alternative form of a gene or in other terms the variant form of a gene. If there are two alleles at a locus p and q are used to represent their frequencies. Frequencies of all alleles in a population will add up to 1.
Therefore, in this case if red allele CW is p=0.7, then the frequency of the white allele in this population (q) is 0.3.
ii) From the punnet square the expected genotypes frequencies in the offspring generation will be 0.49 CRCR (red flowers, o.42 CRCW (pink flowers) and 0.09 CWCW (white flowers).
Answer:Sclerenchyma
Explanation:Sclerenchyma is thick walled dead lignified cells, they are hard and elastic. The sclerenchyma cells are divided into two groups namely fibers and sclereids. Sclerenchymatous fibers are branched/unbranched, long, hard, pointed cells with tapering ends, thick walls, and narrow lumen.
The three correct answers are;
B. forming waxy leaf coverings
D. storing energy in fat cells
E. forming cell membranes
Lipids are a large group of biological molecules that include phospholipids, fats, oils, waxes and some steroids. Almost all lipids are hydrophobic (i.e. insoluble in water). Lipids play many important different functions in a cell. Lipids are vital component of all cellular membranes. They store energy in the form of fats in the body. Waxy coverings on some leaves are composed of lipids. Lipids are also essential for heat insulation, cellular communication and protection.
