Answer:
The correct answer is "#2 and #3 only"
Explanation:
A and a are alleles, and R and r are alleles. Alleles of a gene are found at the same locus on homologous chromosomes. Every pair of the alleles depicts the genotype of a particular gene. Homozygous genotype occurs when two similar alleles at same locus and heterozygous in case of two nonidentical alleles. Due to the alleles there occurs a change in the appearance. An alleles create differences in gene.
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
