What is body condition scoring for? - correct answer Objective score system to determine body condition, evaluate overall muscle mass, and fat coverage of ribs, spine, hips What characteristics would indicate your dog is at a healthy weight? - correct answer Ribs are easily felt Stomach doesn't sag Waist is easily seen from above What characteristics would indicate your dog is overweight? - correct answer ribs are difficult to feel under fat stomach sags and you can grab a handful of fa...

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 ...

The radiation in the belts poses a threat to astronauts and electronic equipment in the area. Temperature data is part of what satellite subsystem?

8. How is a nova different from a type Ia supernova? How does it differ from a type II supernova? - A nova is a smaller energy explosion on the surface of a white dwarf in a close binary system, where fresh material from a donor star is deposited on the surface of the white dwarf until it ignites. A type Ia supernova has a similar configuration, but in this case, the material deposited on the surface of the white dwarf is sufficient to push the white dwarf past the Chandresekhar limit....

define one genetic map unit ~ the physical distance between two genes that results in a 1% frequency of recombination In birds, sex is determined by ZW chromosome inheritance. Males are ZZ and females are ZW. Within pigeon populations there is a recessive, Z-linked allele that is lethal in embryos. What is the expected sex ratio in the offspring of a cross between a male that is heterozygous for the lethal allele and a wildtype female? ~ 2:1 male to female A recessive allele on the X c...
