Answer:
Nitrogenous bases contain the genetic information, their amount is variable among different species, and the arrangement of these bases is also variable among different species
Explanation:
Both Watson-Crick and Pauling's DNA models considered that DNA nitrogenous bases (i.e., Adenine, Cytosine, Thymine and Guanine) contain the genetic information that determines the characteristics of living organisms. Moreover, both DNA models also considered that nitrogenous base composition varies between species, as well as the arrangement of these bases in the DNA chain also varies between species. Based on these features, Linus Pauling considered that a model where nitrogenous bases would be arranged on the outside of the DNA molecule would be easier for the DNA molecule to be replicated, transcribed, or repaired. Although incorrect, Pauling's DNA triple helix model was fundamental to develop the helical (double-stranded) structure of DNA, which was finally discovered by Watson and Crick in 1953.
Answer:
Explanation:
Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (lithosphere), or evaporating into the air (atmosphere). Humans (biosphere) harness energy from the water (hydrosphere) by having it spin turbines (lithosphere) to produce electricity.
Answer: cyclic
Explanation:
This pattern often fits in with daily body rhythms or with the sleep and wake cycle.
For example, Cortisol hormone accumulates early in the day, reduces towards the afternoon, and rises towards the end of sleep and maximizes during the morning hours.
Thyroid stimulating hormone (TSH) rises to the maximum point during sleep and reaches its low point three hours after the individual wakes up.
Growth hormone (GH) levels rise 90 minutes after sleep begins.
Beacuse to be male you have to inherit the Y chromosome from your dad as the mother would be XX and father XY. so males can only inherit these conditions from their mothers beacuse the alleles for theses conditions are found on the X chromosome
