Answer: B - mosses and lichens that can grow on Rocky surfaces
Explanation: Primary succession usually starts or begins on rock outcrops. It could include bare surfaces, volcanic mountains or an area (water surfaces) with no soil.
In primary succession, pioneer organisms including algae, lichen, mosses and fungi usually are the pioneer species. Other abiotic factors like wind and water play roles of normalizing the habitat.
Light. That's the chemical equation for photosynthesis
The nurse should ensure that the absorption of the child
into his body would be reduced. The nurse should also increase the elimination
or excretion of the toxic being taken by the child and he should provide the
supportive care.
1) False. Scientists may predict something but realize a difference soon after before the test, so they could definitely change the hypothesis if they want. It’s only AFTER the experiment they cannot. Because a hypothesis is like a “guess” as to what’s going to happen, right?
2) False. A hypothesis can’t be “valid” because it’s literally a prediction.
3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS
4) True. The conclusion must be based on data because it’s the observation that was seen.
Hope this helps!! I could have answered in short form but I just wanted to make them understandable:)
