Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in living organisms.[1][2][3]
The discoverer of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.
Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded beyond inheritance to studying the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the context of a population. Genetics has given rise to a number of subfields, including epigenetics and population genetics. Organisms studied within the broad field span the domains of life (archaea, bacteria, and eukarya).
Genetic processes work in combination with an organism's environment and experiences to influence development and behavior, often referred to as nature versus nurture. The intracellular or extracellular environment of a cell or organism may switch gene transcription on or off. A classic example is two seeds of genetically identical corn, one placed in a temperate climate and one in an arid climate. While the average height of the two corn stalks may be genetically determined to be equal, the one in the arid climate only grows to half the height of the one in the temperate climate due to lack of water and nutrients in its environment.

Answer:
If a solution has a higher concentration of hydronium ions than pure water, it has a pH lower than 7. A solution with a pH lower than 7 is called an acid. As the hydronium ion concentration increases, the pH value decreases. Therefore, the more acidic a solution is, the lower its pH value is.
Explanation:
It is the most common sexually transmitted disease,
especially among college women. Yes it is painful because it produces painful
sores. Many parents believe that their daughters would become more sexually
active if they took this vaccine. Because
of the women with disabilities are more likely than other women to experience
discrimination, emphasis on physical
attractiveness.
It acts as a framework inside the endoplasmic reticulum and keeps it from collapsing . it helps keep the organelles in place and directs their movement as needed . it keeps the DNA safely enclosed in the nucleus and holds the nucleus together . it provides anchoring places for the cell cytoplasm and help it move molecules . maybe that help :)
