Answer:
The statement is false.
Explanation:
At the base of the oxyntic gland, in addition to the parietal cells, the chief cells (peptic cells) are located, mainly in the lower half of the gastric glands, these cells have large basophilic zymogen granules, more prominent in the apical region and responsible of the secretion of pepsinogen proteolytic enzymes, a relatively constant fraction of pepsinogen I released by the chief cells is absorbed by the blood instead of passing into the gastric lumen. The stomach acid transforms pepsinogen into pepsin, which breaks down proteins in food during digestion.
Question options:
a. state-dependent memory
b. trait-dependent memory
c. context-dependent memory
d. the double blind
Answer:
a. state-dependent memory
Explanation:
State-dependent memory is the phenomenon in which memory recovery is most efficient when an individual is in the same state of consciousness as they were when the memory was formed. The state of consciousness produced by psychoactive drugs ( caffeine or alcohol).
Answer: A. Directional selection
Explanation: Good luck! :D
Answer:
If one parent has blood type B and the other parent has blood type O, the percentage of the blood type of the offspring will depend on the genotype of the parent with blood type B.
Explanation:
Knowing the blood type of the offspring of the cross between parents with blood type B and O raises two possible scenarios, depending on whether the genotype of the parent (type B) is B|B or B|O.
Blood type is an inherited trait and is characterized by the presence or absence of surface antigens A and B in the red blood cells, which genetically behave as co-dominant traits.
- <em>Blood type A</em><em> contains antigen A and its genotype can be A|A or A|O.
</em>
- <em>Blood type B </em><em>contains the B antigen, whose genotype can be B|B or B|O.
</em>
- <em>Blood type AB </em><em>contains both antigens and a single A|B genotypic expression.
</em>
- <em>Type O blood lacks surface antigens, and is the recessive trait so its genotype is O|O.</em>
<u>Scenario 1: Parent with genotype B|B.</u>
In this case, knowing that the genotype for type O is always O|O, all offspring would be of blood type B, genotype B|O.
B|B X O|O
Alleles B B
O B|O B|O
O B|O B|O
100% of the offspring would be of blood type B.
<u>Scenario 2: Parent with genotype B|O.</u>
In this case, 50% of the offspring will have blood type O and 50% B.
B|O X O|O
Alleles B O
O B|O O|O
O B|O O|O
In no scenario would offspring of blood type A be possible.
Answer:
Advantage: Quick Reproduction, Requires no mate, only 1 parent needed
Disadvantage: Can not adapt to change, no genetic diversity, DNA is exactly the same as parent
Explanation:
Advantage: Genetic Diversity, Can adapt to change, Genes are changing each generation
Disadvantage: Slow Reproduction and 2 parents are needed (male and female)
