Answer 1

Answer:

Several variables might affect the germination, these variables include light, temperature, water, soil type, and air quality. ... Remember, that the hypothesis should be a complete sentence that can be tested.

Answer 2

Answer:

Based on the effect of different soil pH on the growth of vegetative traits, reproductive investment and pollen allergenicity of A. artemisiifolia was tested in pots in growth chambers under controlled conditions of light (12 h dark/12 h light, 150 μmol m−2s−1; humidity: 65%) at 25°C for 3 months and half (104 growing days), from 9th April to 22th July, 2015. A randomized complete block design experiment with five replicates (number of individuals was limited by the limited space inside the growth chamber) was carried out to examine the effect of soil pH on plant growth.
