Answer: Even though there are smalll amounts of these gases, they can have a major effect on Earth. For example, increased amounts of carbon dioxide are having a major effect on global warming. :)
Answer:
New crust, sometimes islands/mountains
Explanation:
Divergent boundaries are when two tectonic places are moving away from each other. In the current configuration of Earth, that happens in the ocean.
When plates move away from each other, they leave a gap. That gap is filled with lava that solidifies quickly and forms now crust. If the ocean floor is relatively shallow, and the lava pressure is big enough, that can lead to the formation of new islands, mountains/volcanoes on top of the gap. That's basically how the Galapagos islands were created.
Correct answer is B.
Explanation:
In their nucleus cells contain DNA. The DNA has information about size, shape and function of each cell. When the cell reaches it's full size it stops growing and starts doing whatever it's function is. If more cells are needed then the cell replicates. This explanation excludes answers A and C.
Male and female sexual cells are used to conceive a baby. These cells combine to form a new type of cells. In the first few weeks all types of cells are created. Then the creation of new types of cells stops and existing cells multiply in order to achieve needed number of cells. This explanation excludes answer D.
When we compare an adult person and a baby we can see that, for example, an adult has bigger bones than a baby. This was result of increasing number of existing types of cells without creating any new type.
B & C in my opinion. If it asks for one— B. is what I would choose.
Yes, things such as polluting the air with fossil fuels (not natural) and things like building factories or something as simple as throwing garbage in the oceans have a major affect. everything is like a butterfly effect, one small action can have a drastic outcome. people now a days are inventing numerous amounts of things and damaging our ecosystems. as the years go on and things like this keep happening, our world will start to get hit with those outcomes. right now we are experiencing them, with hot temperatures and less fish in the ocean and polar ice caps melting.
