2 ) is light
3) yes
4) energy that runs off of batteries
Indirectly to the fact that it does not need energy to transport water from a concentration gradient.
Answer:
The correct answer is : B) Wavelength of light is the only variable that has been changed between groups.
Explanation:
In this three plants in three different conditions shows three different outcomes so their is sufficient replication to draw a conclusion. The wavelength of the light affects the growth of the plant. UV light has very low wavelengths below 400 nm than the photons required similarly Infrared light has higher wavelengths that is low energy light, UV can cause wilting and leaf burn.
So, the wavelengths of the light and growth of plant are related and this experiment only wavelengths of the lights are changed.
Thus, the correct answer is : B) Wavelength of light is the only variable that has been changed between groups.
Answer:
The correct option is H) these acids change the environment.
Explanation:
Soil can be described as the part of the environment where plants grow. In primary succession, life stars arising in an area which has no soil and only rocks, This is possible because lichens are the organisms which can grow on the rocks. Lichens secrete certain acids which break down these rocks and hence soil begins to form when these rocks break. This makes it possible for other plant species to grow on these lands.
Explanation:
When you make the cross. You get
HH HH Hh Hh.
So the genotypic ratio - 2:2 which is also 1:1.
The phenotypic ratio - 4. Since Hh and HH are horned organisms. So they only differ in their genotypic make up.
