The answer is: All of the cells of the sea star have the same exact DNA (I think)
Explanation:
Newton’s first law had to do with inertia, which is a property that explains that something in motion will continue in motion unless stopped by a force of some sort.
“An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.”
Answer:
A barometer
Explanation:
It is commonly used to measure atmospheric pressure
Answer:
Through this experiment we study the process of photosynthesis.
• In the begining the leaf disks's tissue has oxygen, this allows them to float.
• Then, in the experiment we infiltrate the leaf disks with a solution that has bicarbonate, and as a result their density changes (it increases) and so the leaf disks sink.
• Once the disks are on the bottom and we direct the light to them the process of photosynthesis starts, being the bicarbonate the source of carbon for the process.
• As we know a product of the photosynthesis proces is oxygen, so when it is released into the leaf disks the overall density changes again and the disks rise.
So as we can see, in this experiment the purpose of the bicarbonate is being the source of carbon for the process of photosynthesis that occurs in the leaf disks.
Answer:
A, Temperature, pH, salinity, precipitation and humidity
Explanation:
Water includes all of these options. Also, water doesn't include wind which is in all three of the other options, so this is the only option that would work. Hope this helps :)
