Answer:
color
Soil can be described based on its color (yellow brown red), how light or dark it is, and how intense the color is.
Texture
Ranges from bolder size pieces to very fine clay
Structure
Describes the shape of soil clumps and how the soil particles are held together. It can look grainy, blocky, or prism shaped.
Consistency
Hardness or softness of soil measuered by its consitstency varies with moisture for example some soils have soft, slippery consiststency when there moist.
Infiltration
How fast water enters soil
Soil moisture
Amount of water in soil pours is its moisture contents scientits detemine weight loss by drying samples in a oven at 100c the weight difference is the amount mouisture in the soil

Answer:
![10\,cos\,2x](https://tex.z-dn.net/?f=10%5C%2Ccos%5C%2C2x)
Explanation:
To differentiate: ![10\,sinx\,\,cos x](https://tex.z-dn.net/?f=10%5C%2Csinx%5C%2C%5C%2Ccos%20x)
Solution:
Use product rule:
and the following formulae:
![(sinx)'=cosx\,,\,(cosx)'=-sinx](https://tex.z-dn.net/?f=%28sinx%29%27%3Dcosx%5C%2C%2C%5C%2C%28cosx%29%27%3D-sinx)
![(10\,sinx\,\,cos x)'=10[(sinx)'cosx+(sinx)(cosx)']\\\\=10[cosx\,cosx-sinx\,sinx]\\\\=10[cos^2x-sin^2x]](https://tex.z-dn.net/?f=%2810%5C%2Csinx%5C%2C%5C%2Ccos%20x%29%27%3D10%5B%28sinx%29%27cosx%2B%28sinx%29%28cosx%29%27%5D%5C%5C%5C%5C%3D10%5Bcosx%5C%2Ccosx-sinx%5C%2Csinx%5D%5C%5C%5C%5C%3D10%5Bcos%5E2x-sin%5E2x%5D)
Use ![cos^2x-sin^2x=cos2x](https://tex.z-dn.net/?f=cos%5E2x-sin%5E2x%3Dcos2x)
![(10\,sinx\,cosx)'=10\,cos2x](https://tex.z-dn.net/?f=%2810%5C%2Csinx%5C%2Ccosx%29%27%3D10%5C%2Ccos2x)
<u>Answer</u>: A) Africa and South America only
As shown in the map, the fossil evidence suggests that Cynognathus lived on the modern day continents of South America and Africa. Thus, from this distribution and the fragmentation of the ancient landmass into today's continents, result in the distribution of Cynognathus offspring species also only within the continents of Africa and South America.
The Answer is B- the land heats and cools more quickly than the water
