Identify and investigate the properties of minerals. Identify and classify a variety of rocks.
based on physical characteristics from their origin, and explain how they are related using the
rock cycle. (i.e. Sedimentary, igneous, and metamorphic rocks)
Answer:
Igneous rocks are classified on the basis of their composition and their texture. Magma, and the igneous rock it becomes, has a range of chemical compositions. For example, basalt is a mafic lava flow rock which originates from melting of the upper mantle.
Explanation:
Answer:
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.

What gases was not present in earths earth atmosphere
Answer:
Primitive Earth (Before life) contained no or very little Oxygen (element#8)
According to scientific theory:
Earth had no oxygen to begin with. It had a lot of carbon dioxide, though. Somehow (We still do not know how they started growing) single-celled Carbon Dioxide-breathing bacteria slowly, over thousands to millions of years, turned most carbon dioxide into oxygen, supporting new types of life.

Which pH indicates a basic solution?
1.
1
2.
5
3.
7
4.
12
Answer:
7
A pH value greater than 7 indicates a basic solution. The more the pH value exceeds 7, the more basic is the solution.
7 is the answer.
If the pH is 1, that means the substance is sour or acidic.
If it has a pH of 5, then it is not that acidic.
If something has a pH of 12, then it is almost completely basic.
If something has a pH of 7, then it is basic.
Hope it helps! :)

Differentiate betweeli population density and
population distribution.
Answer:
The main difference between population density and population distribution is that the population density is the number of individuals per unit land whereas the population distribution is the spreading of people over an area of land. Furthermore, population density is unable to describe where the population actually lives, unlike population distribution.
Population density and population distribution are two measurements of population used in a variety of applications in ecology.
Explanation:
. How much time does it take a person to walk 12 km north at a velocity of 6.5 km/h
Answer:
It will take 1.85 hours to walk 12 km north.
Answer:
Explanation:
v=[tex]\frac{d}{t}[/tex]
and the d here is the distance which is equal 12 km
the time is still unknown
and we know the velocity which is 6.5 km/h
and according to the triangle of the velocity "search that up "
t =[tex]\frac{d}{v}[/tex]= [tex]\frac{12}{6.5}[/tex]≈1.8 hours

How is the plasma membrane of a cell like dialysis tubing?
Like a cell membrane, dialysis tubing has a semi-permeable membrane, which allows small molecule to permeate through the membrane. Thus, the dialysis tubing mimics the diffusion and osmosis processes of the cell membrane (Alberts, 2002). ... Instead, facilitated diffusion would be needed to transport the glucose.
A family paid $ 28,000 as a down payment for a home. If this represents 14% of the price of the home, find the price of the home.
Answer:
175000.00
GBP
16
%
=
28000
so we can also say
100
%
=
x
Then from here the rule says that you do
100
×
28000
16
So if we do that we get a result of
175000
That is the price of the home.
x
=
175000.00
GBP
Explanation:
So we must begin with a rule that is commonly used to work this out.
Hope this worked out <3ASAP PLEASE
