Why do birth control pills contain estrogen apex?

They increase the levels of estrogen in the body because this hormone is not related to the keeping of pregnancy, progesterone does.  The hormones prevent a woman's ovary from releasing an egg during her menstrual cycle. They upset the natural progress of natural hormonal release and repress the hormones FSH (Follicle Stimulating Hormone) and LH (Luteinizing hormone) required for ovulation.

electronic measurement tools display data on a screen after waiting for several minutes.

while some business owners prefer manual record keeping systems, most businesses use an electronic record keeping system - making it easier to capture information, generate reports and meet tax and legal reporting requirements.

explanation:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
