What is the approximate hydronium ion concentration and hydroxide ion concentration in a cup of tea?
Natasha2012 [34]

The hydronium ion is an oxonium ion whose chemical formula is H3O + or H + (aq). It is found in the solid, gaseous or liquid state (protonation of a molecule of water).


The concentration of hydronium ion is directly linked to the pH of the tea (or any solution) by this equation.:

C° (hydronium) = 10^(-pH)


if the pH of the tea is 6 for example, than:

C° (hydronium) = 10^(-pH) = 10^(-6).

Genetic variation helps populations adapt to a changing
timama [110]

Answer:

Please find the explanation below

Explanation:

Sexual reproduction is the kind of reproduction that requires two organisms (male and female) to form an offspring. The male organism produces gametes called SPERM while the female organism produces gametes called EGG. These two gametes come together in a process called FERTILIZATION to produce a zygote, which develops into an offspring.

In sexual reproduction, gametes are produced by organisms involved via a process called MEIOSIS. Meiosis, however, reduces the chromosome number of the gametes by half. However, one process unique to only meiosis and sexual reproduction is called CROSSING OVER.

Crossing over is the process whereby chromosome segments is exchanged between non-sister chromatids of homologous chromosome. This process causes a recombination of chromosomes (alleles) in such a way that the gametes will be genetically different from the parent organisms (genetic variation). According to this question, sexual reproduction leads to more genetic variation than asexual reproduction due to the process of CROSSING OVER that occurs in sexual reproduction.
