So the independent variable is the thing that is changed in an experiment and you want to change the amount of rainfall the cactus gets as the hypothesis is about rainfall so the answer would be c). Hope this helps :)
Answer:
it's D
Explanation:
When weather conditions are ideal, some ferns, algae, moss and even fungi, release spores into the air, often carried by the wind, by insects or birds until they land. Spores contain both male and female reproductive organs, which allows these plants to replicate themselves in a form of cloning.
An air mass that originates in the Pacific ocean, west of Brazil, is most likely WARM AND WET.
A. warm and wet
<u>Explanation:</u>
The pacific ocean has the tropical maritime air mass so it is warm and wet. they affect the United States originate over the Caribbean sea, Mexico, pacific and the western Brazil.
So the air masses in the pacific ocean, western Brazil are wet and warm.the air masses have the fairly uniform temperature and the moisture content in the horizontal direction.
Air masses are characterized by their temperature and the humidity properties. The air mass where the originate is based on the surface properties.
Answer:
They are nonlobed, simple leaves and are attached oppositely on the branch.
Explanation:
A dichotomous key is a tool you use in biology to know the identity of things in nature such as trees,flowers, fish or even rocks. This key has choices that follow each other in a progressive manner, where one choice led to the other until you identify the item.In this case, to identify Dogwood, you follow the below steps;
1b. Broad leaf = Step 2
2b. Simple leaf = Step 7
7a. Leaf bases attached opposite each other on branch = Step 8
8b. Leaves not lobed = Step 9
9b. Leaves not heart shaped = Dogwood
The key is (1b,2b,7a,8b,9b)
