  • Law of Uniformity: When crossing two pure breeds (homozygous individuals with different alleles for a trait), all first filial (F1) generation descendants are genetically uniform and phenotypically identical, expressing the dominant trait if one exists.
  • Law of Segregation: The two hereditary factors (alleles) for each character do not fuse but remain differentiated throughout an individual’

Understanding Amino Acids and Protein Structure

Properties of Amino Acids

Stereoisomerism occurs because the alpha carbon is asymmetric. Stereoisomers are considered two different optical activities. Amino acids can be isomers L, while D isomers are also present. These isomers can influence antibiotic-bacterial properties. The existence of polar groups in amino acids enables hydrogen bonding, which affects their melting points, boiling temperatures, and solubility.

Peptide Bonds

A peptide bond is the union between the carboxyl group of one amino

David Hume’s Empiricism: Causality, Ideas, and Critique

Why is the principle of causality not knowledge derived from relations of ideas? This knowledge is not a truth achieved by reason either intuitively or demonstratively. Reason cannot intuitively link cause and effect, as they are distinct and separable ideas. Furthermore, this knowledge cannot be reached via demonstration because the opposite (i.e., an effect not following its supposed cause) does not involve any logical contradiction or absurdity. The
