White Dwarf "Star" correct answers Result of the death of a low mass star The exposed core of a low mass star; -hot -dense -mostly carbon If there is no new energy production in a white dwarf, what prevents gravity from crushing it? correct answers Electron degeneracy pressure White dwarf "stars"- electron degeneracy pressure correct answers Electron degeneracy pressure will only hold up a star to about 1.4 solar masses, above that gravity will begin to win, resulting in the st...

White dwarfs: properties - Remaining cores of dead, low mass stars Electron degeneracy pressure supports them against gravity Slowly fade with time Sirius and its hot WD companion White dwarfs with same mass as Sun are about same size as Earth; slowly cooling Typical density 10^6 gram / cubic cm Higher mass white dwarfs are smaller Cannot be more massive than 1.4MSun, the Chandrasekhar limit WDs in binaries: nova, supernova Type I - Mass falls toward white dwarf from binary companion ...

dark energy + evidence correct answers a mysterious repulsive force that appears to be causing the expansion of the universe to accelerate Type Ia supernovae as standard candles; Hbl law says they should be moving faster there; inverse square law for light dictates that dimmer = farther; calculated dstncs to things are even farther than their redshift predicts; they are being pushed away dark matter + evidence correct answers matter (gravity, attractive force) that does not give off electr...

Briefly explain how the base pairs A-T and C-G bond to each other and why the interactions they form are important to DNA unwinding. Base pairs form hydrogen bonds to each other. G and C form 3 hydrogen bonds, while A and T form 2 hydrogen bonds. These hydrogen bonds are weak electrostatic interactions that are able to hold the DNA together but are easily broken for the DNA to unwind. Why are telomerase inhibitors an attractive prospect for cancer therapies? >90% of cancer cells expres...

The original paper (Berezin, 1997) delves into critical inquiries concerning quantum black holes, their mass spectrum, the dynamics of self-gravitating spherically symmetric dust shells, and their relationship with Hawking's radiation. Nonetheless, upon a thorough examination of the paper, it became evident that specific queries or aspects required expanded responses. Presented below are seven questions that I aim to address comprehensively. 1. Detailed investigation into the symmet...

True or false? The genetic code is degenerate, meaning that a codon can specify more than one amino acid. Ans: False The degeneracy of the genetic code means that an amino acid may be coded for by more than one codon. However, a single codon can only ever specify one amino acid. A DNA sequence produces a mutant protein in which several amino acids in the middle of the protein differ from the normal protein. What kind of mutation could have occurred? Ans: An addition and a deletion muta...

1. What is the ultimate source of all genetic variation? - a. Mutation 2. Which of the following is the best example of the degeneracy of the genetic code? - a. GGG, GGC, GGU and GGA all code for the amino acid glycine. 3. On average, how much of your genetic material do you share with a full sibling? - b. 50% 4. Why did the traits Mendel examined in his pea plant subjects segregate into such predictable frequencies? - a. They were either on different chromosomes or far enough apart on...
