Answer:
The force of surface tension in the lungs is so great that without something to reduce the surface tension, the airways would collapse after exhalation, making re-inflation during inhalation much more difficult and less effective. Collapse of the lungs is called alectasis.
Explanation:
Answer:
The benefits and harms of learning about my DNA are mostly in medical, personal, civil and criminal fields.
Explanation:
a) Pros: learning about my genome sequence could provide new information on the genetic basis of poorly understood diseases with the potential to provide new therapies, immediate benefits based on the current understanding of genetic and health. Being aware of elevated risks for known diseases could allow me to make proactive decisions about my health such as visiting the doctor frequently for more check ups, screening. Choosing one type of prescription drug over another based on my metabolism, changing my diet or exercise plan, informing reproductive decisions, moreover, I would personalize my health care precisely.
b) Cons: the potential harms are the privacy invation, database exposure , which could lead to serious implications for the criminal justice system, which generally seeks to increase the availability of DNA samples from the population. It would create genetic discrimination, meaning that would be harder to find jobs, contract insurance, even though we have a Genetic Information Nondiscrimination Act.
Answer:
Fast-Twitch Fibers: baseball pitching
Slow-Twitch Fibers: long distance swimming, long distance running
Answer:c. each of two alleles for a given trait segregate into different gametes.
a. it possible to determine the genotype of an individual of unknown genotype who exhibits the dominant version of a trait
Explanation:
The law of segregation of genes is examplifed with MEIOSIS 1 ,where sister chromatides ( alleles of a gene on the same locus) separated and behave independently of each other by positoning themselves on different spindles at Metaphase 1 for crossing over and independent assortment.
They migrated independently at Anaphase 1 to reach the equators which afrer telephase 1 and Telophase 2 i are located in different gametes.
Therefore the alleles of the genes behaved independently of each other,carting different genetic components to gametes.
