Answer: Tt
Why? Heterozygous mean two different genotypes, meaning you need both dominant and recessive. So Tt
Hope this helps :D
Answer:
a. A natural geological challenge that exists in my environment is a fault zone known as the San Andreas Fault. It's a major geological landmark where two tectonic plates meet in California. People in my area are prepared for the event of an earthquake by packing emergency clothes, food, water, shelter, etc. in the event of a major earthquake. Scientists believe that California is past due for a major earthquake in the 6.0-8.0 range that could happen any day now. Hope this helps :)
Explanation:
Answer:
CCK
Explanation:
Cholecystokinin (CCK) acts by generating gallbladder contractions and relaxing the Oddi sphincter together with the action of secretin (another hormone secreted by the gut) that stimulates bile production and decreases acid secretion in the stomach.
When stomach acid is high, it stimulates the secretion of another hormone, secretin, which causes decreased gastrointestinal motility. This has the effect of stopping the transfer of stomach contents to the duodenum, preventing the stomach from emptying too quickly. Secretin in conjunction with CCK will also act on the stomach glands, inhibiting acid secretion.
That's intimidating, lol!
Okay so choice A says that #8 is heterozygous for the trait which means for example it would have the genotype Aa. She's a female witht he dominant trait. This is a possibility.
Choice B says #10 is heterozygous, but if it has the recessive trait it would have to have the geotype aa which is homozygous so this one is wrong.
Choice C says #13 is homozygous dominant which means the genotype will be AA. The individual can still have the dominant trait without having the AA genotype (it can also be Aa) so this one is wrong.
Choice D says that #3 is homozygous dominant but like with choice C, the chart doesn't specify the genotypes of each so it'd be a guess to say that #3 is homozygous. This is wrong.
This means that choice A is true!
