100 POINTS+BRAINLIEST: 8th grade science- can someone please explain why water is found in organisms more than DNA, if every single living thing has DNA and water??
is the "correct answer" wrong?
Answer:
Hey there!
You are right by saying that "every living thing has DNA" but water is is the most abundant molecule in cells, accounting for 70% or more of total cell mass.
Water is found in every single cell and that too 70%
Hope it helped you! ^^
Answer:
Water is found in every organism more than DNA. I say this because most organisms have bodies that are filled to 90% with water.

Why are there craters on the Moon? (i can't find science or Selenography)
Answer:
Craters on the Moon are caused by asteroids and meteorites colliding with the lunar surface. The Moon's surface is covered with thousands of craters. Unlike the Earth, the Moon has no atmosphere to protect itself from impacting bodies.
Explanation:
Answer:
There are craters in the moon caused by asteroids and meteorites colliding with the moons surface
Explanation:
Unlike Earth it doesnt actually have a atmosphere to protect itself from being struck by the asteroids and or meteorites since our atmosphere pushes back anything entering if it can reach the inside of the object it could break it apart from the inside which is why many rockets are set up with protective layers to avoid being split apart during re entering.

Explanation:

What are igneous rocks?
Igneous rocks are one of the three main rock types the other two including sedimentary and metamorphic rocks.These rocks are formed by cooling and solidification of lava or magma.
The magma is derived from partial melts in the planet's mantle or crust.Melting is caused by increase in temperature or decrease in pressure or even change in composition.Solidification occurs either below surface which is called as intrusive rocks or on the surface as extrusive rocks.
They are classified according to their texture,mode of occurrence,chemical composition,geometry and mineralogy of rock.The two important variables for classification are mineral composition and cooling history.

What is the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis according to the balanced equation: 2H2O yields 2H2 + O2
Taking into account the reaction stoichiometry, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.
Reaction stoichiometryIn first place, the balanced reaction is:
2 H₂O → 2 H₂ + O₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
H₂O: 2 molesH₂: 2 molesO₂: 1 moleThe molar mass of the compounds is:
H₂O: 18 g/moleH₂: 2 g/moleO₂: 32 g/moleThen, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
H₂O: 2 moles ×18 g/mole= 36 gramsH₂: 2 moles ×2 g/mole= 4 gramsO₂: 1 mole ×32 g/mole= 32 gramsDefinition of theorical yieldThe theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.
Theorical yield of O₂The following rule of three can be applied: if by reaction stoichiometry 36 grams of water form 32 grams of oxygen, 29.2 grams of water form how much mass of oxygen?
[tex]mass of oxygen=\frac{29.2 grams of waterx32 grams of oxygen}{36 grams of water}[/tex]
mass of oxygen= 25.956 grams
Finally, the theoretical yield of oxygen when 29.2 g of water are decomposed by electrolysis is 25.956 grams.

What effect does this arrangement have on the tidal range?
A. The tide is larger than normal because the gravitational forces of the sun and moon pull in the
same direction.
B. The tide is larger than normal because the gravitational forces of the sun and moon pull in
opposite directions.
C. The tide is smaller than normal because the gravitational forces of the sun and moon pull in
the same direction.
D. The tide is smaller than normal because the gravitational forces of the sun and moon pull in
opposite directions.
Answer:
A. because this is a spring tide.
Explanation: The sun and the moon are working together, their gravitational forces pull on the tides more. Your question said "The tide is larger than normal because the gravitational forces of the sun and moon pull in the same direction". They are working together to cause higher than normal tides.

100 POINTS+BRAINLIEST: How do you balance a chemical equation step by step? Please explain in simple language, give definitions to complex words and provide some rules to remember when balancing the equations. Use C3H8+O2—> H2O+CO2 as an example. THANKS SO MUCH!!!
Answer:
list all the elements.
you need to find a number to multiply both sides to get the same result.
example: I said on the left side: 5×O2 which is 10. on the right side I do the same to get 10.
In order to do this I said: 4×H2O which is 8 H2,and 4 O.
I then said 3×CO2 which gives 3 C and 6 O2. 6+4=10.
Now Oxygen(O) is balanced. Do the same for the rest of the elements.
Explanation:
pls mark as brainliest thanks!
Let's use
C3H8+O2—»H2O+CO2Calculate atoms on both sides
On reactant side
C=3H=8O=2On product
H=2O=3C=1Now balance both sides by making atoms equal
The balanced one is
C3H8+5O2—»3H_2O+4CO_2Explain what a trait is in your own words.

help meeee
i don’t want the sample response!
Once again rocks and/or minerals
How could you determine whether
an unknown substance is a mineral?
Answer:
you can classify a mineral by its appearance and other properties. The presence of a mineral is defined by the color and luster, and the color of the powdered mineral is described by the band. Every mineral has a distinctive density. To compare the hardness of rocks, the Mohs Hardness Scale is used.
Explanation:
Answer:
Luster, hardness , colour , clevage and magnetism
Explanation:
1. Luster makes sure the light is reflected by the mineral.
2. On the 10-point Mohs scale, which is basically a scratch test, hardness is measured. Take an unidentified mineral and scrape it like a fingernail with an object of known hardness.
3. Zurite, for instance, is often a deep blue, and malachite is gray.
4. In minerals that appear to divide along one or more flat surfaces or planes, cleavage may be observed.
5. Magnetite, for instance, has a heavy pull that even weak magnets can draw. But there is only a poor attraction to other minerals, particularly chromite (a black oxide) and pyrrhotite (a bronze sulfide.)

We mixed baking soda with vinegar and drew on a piece of paper when it was done bubbling, then took a sponge and covered the paper in grape juice.
Answer: ph scale
Explanation:
When baking soda is mixed with vinegar, bubbling is observed. This is because of a chemical reaction which involves the evolution of carbon dioxide gas. This reaction is used as an indicator of carbon dioxide.
What is an Indicator?An indicator in chemistry is any substance that gives a visible sign or indication of a chemical species by a change in color. An indicator is generally used to identify an acid or an alkali present in a solution.
Indicators are weak acids or alkalis that show a change in color as the concentration of hydrogen ions in solution changes. Commonly used chemical indicators include Litmus, turmeric, Methyl Orange, phenolphthalein, etc.
When baking soda is mixed with vinegar evolution of gas bubbles is observed. This gas when passed through lime water, the solution turns milky which confirms the presence of carbon dioxide in solution.
Therefore, chemical indicators can be used in identification of a chemical species.
