Answer:

The major oxygen reserves present on earth are:

  1. Atmosphere: Around 21 percent of the oxygen by volume is present as free oxygen. Other oxygen-containing molecules include ozone, water vapors, carbon dioxide, oxides of sulfur and nitrogen.
  2. Biosphere: Around 22 percent of the oxygen by volume is present as the composition of organic matter and water molecules.
  3. Hydrosphere: Around 33 percent of the oxygen by volume is present in the hydrosphere. It is present in the form of dissolved oxygen, components of water molecules and carbonic acids.
  4. Lithosphere: Around 47 percent of the oxygen by volume is present as oxide minerals such as silica minerals et cetera.

Explain Gynecomastia in males.
PolarNik [594]

Gynecomastia is an increase in the size of the mammary gland in men. The condition can occur in one or both breasts. It starts as a small mass under the nipple, which can be sensitive. One breast can be bigger than the other. Its cause is an imbalance between the stimulatory effects of estrogen (female sex hormones) and the inhibitory effects of androgens (male sex hormones) in the breast tissue, when the first ones increase, or the second ones descend.

Gynecomastia is a problem relatively common in the population, and there are three prevalence peaks throughout life:

Newborns: Between 60 and 90% of newborns have gynecomastia, produced by the passage of maternal estrogens through the placenta. It is a transient gynecomastia that disappears in about 2-3 weeks.

Puberty: Gynecomastia in puberty affects mainly young people aged between 10 and 14 years, and is due to the transient and physiological increase in estrogen that occurs at this age.

Elderly: Is due to an increase in fatty tissue with a greater peripheral aromatization ( a process that occurs in adipose tissue and that involves the conversion of androgens into estrogens), a decrease in the production of testosterone by the testes and the use of drugs.

The biofilm can present one of the most important species of microorganisms, depending on the duration and its location. Gram-positive, Gram-negative and yeast. In addition, the cellular elements may be attached to the biofilm, such as platelets, for example, when the biofilm is installed on the blood-soaked surface.Several factors contribute to the formation of biofilms.

In addition, the cellular elements may be attached to the biofilm, such as platelets, for example, when the biofilm is installed on the blood-soaked surface.Several factors contribute to the formation of biofilms, depends primarily on the number and type of cells present in the liquid to which the surface is exposed and the rate of flow of this liquid across the surface. The physical chemical properties of the surface, the nutritional composition and ambient temperature will also interfere with this speed. The presence of antimicrobials in the medium may affect the formation of biofilms.
