Answer:
Hydrochloric acid Prepares protein for digestion (denaturation) Activates enzymes and “Disinfection”
Pepsin (an enzyme) Begins protein digestion
Gastric lipase Some lipid digestion
Gastrin (hormone) Stimulates gastric secretion and movement
Intrinsic factor (a glycoprotein) Needed for absorption of vitamin B12
Explanation:
Answer:
Atelectasis occurs from a blocked airway (obstructive) or pressure from outside the lung (nonobstructive). General anesthesia is a common cause of atelectasis. It changes your regular pattern of breathing and affects the exchange of lung gases, which can cause the air sacs (alveoli) to deflate.
Answer:
Monohybrid cross:
Monohybrid cross may be defined as the cross done by taking single trait at a time. The ratio of the monohybrid cross by the pure parent breed result in the formation of 3:1 phenotype in the second generation.The genotype ratio is 1:2:1.
Test cross:
Test cross may be defined as the cross between the unknown genotype and the recessive parents. This cross is done to determine whether the genotype is heterozygous or the homozygous dominant trait. The ration of the cross may vary depending on the genotype of the organism.
The correct answers A false
Answer:
Certain fossils, called index fossils, help geologists match rock layers. To be useful as an index fossil, a fossil must be widely distributed and represent a type of organism that existed for a brief time period. Index fossils are useful because they tell the relative ages of the rock layers in which they occur.
