単位の換算:1 に等しい係数を、元の単位が消えるように書いて掛けます:3 ft × 12 in/1 ft = 36 in。メートル法の長さ:1 km = 1000 m、1 m = 100 cm = 1000 mm、1 cm = 10 mm。米国の慣用単位:1 ft = 12 in、1 yd = 3 ft、1 mi = 5280 ft、1 gal = 4 qt、1 qt = 2 pt、1 pt = 2 cups、1 ton = 2000 lb。時間:1 h = 60 min、1 min = 60 s、1 day = 24 h、1 week = 7 days。小さい単位で表すと、数は大きくなります。
In this method, called somatic cell nuclear transfer, the clone gets its nuclear DNA from the donor of the body cell. Only the small amount of mitochondrial DNA came from the egg.
答え
B · The sheep that gave the body cell nucleus
16.看護学校入学試験のための生物
答え: D · The zygote's mitochondria come from the egg
これが答えになる理由
The egg provides the cytoplasm of the zygote, including its mitochondria. Sperm mitochondria do not normally survive in the embryo, so mitochondrial DNA is inherited from the mother.
答え
D · The zygote's mitochondria come from the egg
17.看護学校入学試験のための化学
答え: C · Mass number stays the same and atomic number rises by 1
これが答えになる理由
In beta decay a neutron becomes a proton, so the atomic number rises by 1. The total of protons plus neutrons is unchanged, so the mass number stays the same.
答え
C · Mass number stays the same and atomic number rises by 1
18.看護学校入学試験のための化学
答え: C · At low temperatures the reaction is too slow to be useful
これが答えになる理由
Lowering the temperature favours ammonia at equilibrium, but makes the reaction very slow. A compromise temperature with an iron catalyst gives an acceptable yield quickly. High pressure is also used to favour ammonia.
答え
C · At low temperatures the reaction is too slow to be useful
