The answer is D. Iron
Explanation:
Answer: Option D iron
Explanation: its right if you go to k12
The two categorical ways of thinking about the matter are discussed in the passage are physical and chemical.
The matter has been the unit, from which everything is made up of. The passage asks about the matter has been the part of each and every physical and chemical reaction.
All the matter has an atom as its smallest building block. The elements listed in the periodic table also matter. The smallest and the biggest entity has consisted of matter.
The physical categorial way of thinking of matter involves the properties that can be sensed by the five human senses. The things that can be seen, heard, tasted, touched, and felt are all matters.
The chemical properties of the matter that result in the formation of a new matter that is irreversible in nature.

Answer:
There's no passage but I can say that matter are that ''thing'' which extend through all Universe, matter is everything. It can be seen or felt as liquid, gas or solid. This changes of its state depend on the amount of energy that is involved.
So, here is used categorical thinking because is a abstract concept that is hard to understand sometimes. It's abstract when we say that matter is all, not just what we see, but even what we don't see like ''Dark Matter'', which is the majority in the Universe.
Surface fire
Answer:
The correc answer is C. greenhouse gases.
Explanation:
The atmosphere is a layer of gases that surrounds our planet and is one of the essential elements for life on it.
The atmosphere protects us from harmful solar radiation from the Sun. The Sun, in addition to light and heat (infrared radiation), emits other radiation such as gamma rays, X-rays and ultraviolet rays that are harmful to life. These harmful radiations are absorbed by the atmosphere.
The atmosphere also protects us from the impacts of meteorites. These are from outer space are attracted by gravity and fall on the earth's surface. Upon coming into contact with the gases of the atmosphere, at high speed, the friction causes them to heat up so much that they become incandescent and end up disintegrating, avoiding reaching the ground. Only the largest (rare) can pass through the atmosphere and reach the ground.
Something similar happens that with meteorites occurs with the dangerous particles of space.
Greenhouse gases contribute, to a greater or lesser extent, to the increase of the greenhouse effect, since they are capable of absorbing the heat energy carried by long-wave radiations that are reflected by the Earth's surface.This phenomenon prevents the solar energy constantly received by the Earth from returning immediately to space and causing the temperature of the air near the ground to rise. Then there are changes in the climate such as sea level rise, changes in rainfall, disappearance of forests, extinction of organisms and problems for agriculture.
So the correc answer is C. greenhouse gases.
Answer:
Example:
0.0001 = 1 x 10-4
you can you 0 for applying weight or volume
Answer:
Expressed in kilograms, the mass of 0.098kg should still have two important digits. 0 is essential because if you don't use the zero after the decimal point then you will be using the incorrect measurement.
Hope this helps.
