Answer:
oxytocin
Explanation:
The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal
Absence of oxygen means anaerobic respiration ; which has 2 different pathways.
First Pathway ; Alcoholic fermentation which takes place in yeast.
Pyruvate is decarboxylated into ethanal releasing co2 as waste product.
Ethanal is toxic , so its reduced by help of NADH to ethanol in presence of alcohol dehydrogenase enzyme , and Free NAD is released to continue glycolysis.
2) The second pathway is Lactic fermentation which takes place in mammalian muscles.
Pyruvate accepts hydrogen and is converted to lactate by the help of enzyme lactate dehydrogenase , again free NAD is released to continue glycolysis.
Hope I made it clear enough :)
Answer:
Paramecium.
Explanation:
Ciliates are group of protozoans organisms that are characterized by special organelles called cilia.
Cilia is used for loccomotion in ciliates and can also be use to move food into the body. The cilia can be use for swimming, crawling, for attachment and sensation. Some ciliates are free living while some are parasitic. They are found in the aquatic habitats both fresh water and ocean.
Saccharides are the monomers which are combined to form carbohydrates.
Depending on the type of carbohydrate, the monomer components can be monosaccharides, disaccharide, polysaccharide, etc.
E.g: Sucrose is a carbohydrate (specifically a dissacharide) that is made of glucose and fructose monosaccharides.
Another example is cellulose, which is a carbohydrate (specifically a polysaccharide) that is made of beta glucose monosaccharide components combined together.
Answer:
Reservoirs
Explanation:
Glaciers serve as reservoirs in the water cycle since they can store water for long periods of time. A biogeochemical or nutrient cycle is composed of
- reservoirs, in which the biogeochemical or nutrient is stored, and
- the several processes by which the biogeochemical or nutrient is cycled between its reservoirs.
