Physical sci
What is considered a base
Anything with a ph scale higher than 7 (8 - 14)
What is different in animal cells compared to plant cells
Vacuole size, lack of cell wall, rounded in shape, and lacks chlorophyll
is an experiment always gonna be correct the first time?
Obviously not which is why multiple people have to test it multiple times
Is it possible for sedimentary rocks to become metamorphic?
Obviously yes because with enough pressure any rock type can become metamorphic
What atom has the atomic number of 1
Hydrogen
Metals
Is it eukaryotes or prokaryotes that have the nucleus?
It’s eukaryotes that have the nucleus
Is it important to use scientific method?
Obviously it is because that’s quite literally the foundation of science as a whole
How are igneous rocks formed?
Magma cooling on the outside of a volcano hardening into a rock
How do you figure out the amount of electrons?
You have to see how many protons are on the element by subtracting half of the atomic mass because protons and neutrons make it up and the remaining number rounded to the closest number is how many protons and electrons are on an element
What is considered alkaline?
Any liquid with a ph of 7 or higher
What is the job of the ribosomes?
To produce proteins to send to the Golgi apparatus that ships the proteins out to the entire cell
What could be considered a dependent variable
How test scores are affected by how long someone sleeps
Where are sedimentary rocks usually formed?
Most likely in bodies of water being pushed and grinded against other rocks that weather it down
If hydrogen has the atomic number of 1 what element has the atomic number of 5?
Boron
Would milk be considered an acid?
Yes because it has a PH level less than 7
It obviously is important since it helps keep the organelles in place and makes the cell functional
How many times is the ideal amount to test an experiment?
3 to 6 times
If an igneous rock were to be buried deep underground then compressed what would it turn into?
A metamorphic rock
What is the atomic symbol of gold?
Au
Is drain cleaner a high alkaline or low alkaline solution?
High alkaline because most cleaning products have a ph of 10 or more
Name 5 organelles that work in unison to function in a cell
Nucleus, smooth and rough endoplasmatic riticulums, mitochondria, and ribosomes
If you were to do an experiment you saw online, and get a different result from the experiment would it or would it not be reliable
No! Because the poster could’ve changed what they did midway through and just keep the previous instructions or just blatantly lie
What are 3 different ways rocks are able to be weathered down
Physical weathering, chemical weathering, and biological weathering
If an atom with 30 electrons has 2 electrons in the first shell 8 electrons in the second how many are in the third and fourth shells?
18 in the third and 2 in the fourth
