Some good mutations would be like if there is a moth that is normally brown because that are how the trees are, then the trees change colors because of lets say pollution, the same mutation could happen to the moth will happen to it.
<span>a) Table salt: it is a compound. A compound is a combination of atoms in fixed proportions.Table salt is NaCl, which means that table salt is a compound of 1 atom of Na and 1 atom of Cl and not other thing. b) Blood: is an homogeneous mixture: it is a mixture of many compounds which can not be easily distinguished or separated, you need microscopes or very special physical methods to distinguish or separate the different compounds of blood. d) Steel: it is a special king of homogeneous mixture (it is called an alloy) which, as in the case of blood, cannot be distinguished or separated easily. d) Planet earth: it is a heterogeneous mixture. You can easily distinguish many of the compounds of the planet Earth: water, oxygen, carbon,...</span><span />
The amount of heat absorbed or released by the system can be determined by the equation:
U = mCpΔT
where:
m = mass of material
Cp = specific heat capacity of material; in this case, Cpwater = 4.186 J/(g-°C)
ΔT = change in temperature of material
U = 18(4.186)(20-(-10)) = 2260.44 Joules or B.
A positive term means energy was absorbed.
Landslides and slumps are forms of mass movements. Types of erosion both move, in different ways. In slumps, land breaks off in one piece, or chunk. Landslides are when rocks and dirt rapidly move down a slide.
Answer:
Explanation:
First you should calculate the volume of a big sphere,so:
Then you calculate the volume of a small spehre, so:
Finally you subtract the two quantities:
