However, when feelings of intense fear and distress are overwhelming and prevent us from doing everyday things, an anxiety disorder may be the cause. Anxiety disorders are the most common mental health concern in the United States. An estimated 40 million adults in the U.S., or 18%, have an anxiety disorder. Approximately 8% of children and teenagers experience the negative impact of an anxiety disorder at school and at home.
Sexual Reproduction: Sexual reproduction promotes genetic variation by producing different gene combinations. Meiosis is the process by which sex cells or gametes are created. Genetic variation occurs as alleles in gametes are separated and randomly united upon fertilization. The genetic recombination of genes also occurs during crossing over or the swapping of gene segments in homologous chromosomes during meiosis.
Best Answer: First of all the process of Meiosis in the development of gametes for sexual reproduction inceases variation by producing genetically non identical gametes. Sexual reproduction occurs by random fusion of gametes also increasing variation.Meiosis is a type of division to produce haploid gametes for sexual reproduction and takes place in the seminifrous tubules in the testes of male (humans) and in the ovaries of females.In plants the male sex cell (pollen) is produced in the anthers and the female sex cells (ovules) takes place in the ovary.Meiosis I halves the number or chromosomes. (a reduction division) Meiosis II doubles the number of cells to give four haploid gametes.n plants the male sex cell (pollen) is produced in the anthers and the female sex cells (ovules) takes place in the ovary.
