Different organisms have different "habitats." These are all examples of habitats: The tops of banana trees in a rainforest The moist area inside a log on a forest floor The sand on the bottom of a shallow area of the ocean Which survival need best defines "habitat"? oxygen or carbon dioxide someplace to live food water
Answer:
Oxygen/Carbon dioxide
Explanation:
The basic description of living things are organisms which have a cell system to produce energy with either primarily via respiratory exchange abilities, by the existence .
The primal survival need for a possessing a habitat would have to be oxygen/carbon dioxide present,

Qualitative or Quantitative?
Answer:
Quantitative
Explanation:
Quantitative statements involve numbers. (Ex: The house has 4 bedrooms.)Qualitative statements describe characteristics. (Ex: The house is blue.)Suppose you know the number of protons in an atom. What other information would you need in order to determine the mass of the atom? Explain your reasoning. Help Plz
Answer:
Number of neutrons
Explanation:
The mass of an atom is roughly the sum of the number of protons and neutrons it has. If you have the number of protons, all you would need is the number of neutrons to determine the mass.

1. Explain how this chemical reaction represents the law of conservation of matter.
Answer:
This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
Which of these statements contains an inference? Question 10 options: After three substances were mixed with a blue liquid, the well plate got warmer. No chemical reaction occured in well #5. Upon mixing, the liquids had a milky appearance. The substance was heated and a clear liquid formed.
Answer:
None
Explanation:
In reporting experimental procedures/analyses, the inference is made after multiple observations have been summed up, to find the nearest possible outcome that explains the phenomenon.
If all options are listed in the question, nothing was inferred after the procedure and observation.
An example of inference would be "CO23- present" or "Chloride formation"
I hope this explanation is clear.
A teacher is preparing the materials list for an activity that all 6th graders will
complete. Each student will create a scale model of the planets in Earth's solar
system. A student will need 2,250 mg of clay to create a model of Mercury.
What two conversion factors will the teacher need to use in determining how
many kilograms of clay to order?
Answer:
There are 1000 mg in 1. g
There are 1000 g in 1 kg
Each students needs 2,250 mg of clay
Explanation:
In order to determine the amount of how many kilograms to order, the teacher will need to find out the total mass of clay required by the students and then the teacher will have to convert the total mass to the units required for the purchase.
The teacher would have to find out how many milligrams make one kilogram as follows
1 kg = 1000 g
1 g = 1000 mg
Therefore, 2,250 mg = 2250/1000 g = 2.25 g
2.25 g = 2.25/1000 kg = 0.00225 kg.
A metal cube has a mass of 20 g and a volume of 5 ml. What is the density? Is the cube made of pure aluminum? Explain your answer in the "other" area. * A.2.7 g/mL B.4 g/mL C.100 g/ml D.Yes it is aluminum E.No it is not aluminum Other:__________________________________________________________
Explanation:
Given that,
Mass of metal cube, m = 20 g
Volume of cube, V =5 mL
We need to find the density of the cube. Mass per unit volume equals density.
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{20\ g}{5\ mL}\\\\d=4\ g/mL[/tex]
So, the density of the cube is 4 g/ml.
We know that the density of Aluminium is 4 g/mL.
So, the cube is not Aluminium cube.
The density of Aluminium is 2.7 g/mL. The cube is not the Aluminium cube.So, option B and E is correct
Mass of metal cube, m = 20 g
Volume of cube, V =5 mL
The formula for density is as follows:-
[tex]Density=\frac{Mass}{Volume} \\\\[/tex]......(1)
Substitute 20 g for mass, and 5 ml for volume in the above equation as follows:-
[tex]Density=\frac{20\ g}{5\ mL} \\\\=4\ g/mL[/tex]
So, the density of the cube is 4 g/ml.
We know that the density of Aluminium is 2.7 g/mL. So, the cube is not the Aluminium cube. So option B and E are correct.

a fruit salad bowl is classified as which of the following
Answer:
its a heterogeneous mixture.
Explanation:
The heterogeneous mixture has a non-uniform composition and has two or more phases. It can be separated out physically.
A homogeneous mixture is a solid, liquid or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixture has components in which proportions vary throughout the sample.
Examples of Heterogeneous Mixtures
Sugar and sand form a heterogeneous mixture. If you look closely, you can identify tiny sugar crystals and particles of sand. Ice cubes in cola form a heterogeneous mixture. The ice and soda are in two distinct phases of matter (solid and liquid).

Periodic Table: Which families are highly reactive? Which family is unreactive?
The families that have the highest reactivities are the a lkali metals and earth alkali metals . These are located far left on the periodic table. They are highly reactive because they have an shell with only 1 electron and need to complete the shell to become stable. The family that is unreactive is inert elements or noble gases.
The alkali metals (lithium family) are highly reactive while the noble gases (helium family) are highly unreactive.
What are alkali metals?The alkali metals are the elements of group 1 in the modern periodic table which are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
All alkali metal has their outermost electron in the s-orbital with the outer configuration ns¹. The alkali metals easily lose the outermost electrons to form cations with charge + 1. Therefore they are highly reactive and are stored under oil to stop the reaction with air.
The noble gases have completely filled electronic configurations. The noble gases have a general outer configuration ns²np⁶ so they have completely filled valence shell therefore, they do not feel any attraction for other atoms. Therefore, noble gases exist in monoatomic form. Therefore, noble gases are highly unreactive and also known as inert gases.

A "carat" is a unit of mass defined as exactly ⅕ of a gram. There are exactly 5 carats in a gram. How many carats would a 1.0 mL diamond have?
Answer:
17.55 carats
Explanation:
First, there is a need to know the mass of 1.0 mL of diamonds. The density of diamond is 3.51 g/mL and density is the ratio of mass and that of volume. Hence;
mass of diamond = density of diamond x volume.
Since the volume of the diamond is 1.0 mL and the density is 3.51 g/mL,
mass of 1.0 mL of diamond = 3.51 x 1.0 = 3.51 g.
1 g = 5 carats, therefore 3.51 g would be;
3.51 x 5 = 17.55 carats.
Hence, there would be 17.55 carats of diamond in 1.0 mL of diamond.

The expression “like a ton of bricks” means “very hard.” Would being hit by an actual ton of bricks hurt if it happened on the moon? A. Yes, it would hurt because the bricks would still have the same weight B. No, it would not hurt as much because the bricks would have less weight C. Yes, it would hurt because the bricks would still have the same mass D. No, it would not hurt as much because the bricks would have less mass.
Answer:
The correct option is;
C. Yes, it would hurt because the bricks would still have the same mass
Explanation:
Given that the expression "like a ton of brick" refers to the tendency of an object being crushed by another object, which is due to the impact of the force, and from Newton's law a force is proportional to the rate of change of momentum produced, therefor if the brick of the same mass is given the same velocity as it had on the Earth while the person remains stationary, it will hurt if the brick hits the person.
Convert 0.95 kilograms into centigrams. (1 g = 100 cg; 1 kg = 1000 g)
Answer:
95,000 centigrams
Explanation:
There is 1000 CG in 0.01 kilograms
so you do 1000*95 which equals 95,000 centigrams.
If the mass of an object stays the same but its volume decreases, will the density increase or decrease?
Answer:
Increase
Explanation:
Density = Mass ÷ Volume
Let the mass be 100 for instance and the original volume to be 4.
100 ÷ 4 = 25
The new volume let it be 2.
100 ÷ 2 = 50
50 is more than 25 so the density increases
