The combined mass of rock 1 and 2 = 19.28 + 25.3
= 44.58
Difference between rock 3 and combined rocks
= 46.3 - 44.58
= 1.72 grams
therefore, the third rock was 1.72 grams greater than the combined mass of the other two rocks.
<em>the function of epidermis is to protect the leaf
make it air tight
prevent water loss as it is waxy
also it is transparent and allows all light to enter...
chloroplast is required for carrying out process of photosynthesis...
as epidermis is not specialized to carry out photosynthesis... so it does not have any chloroplast...</em>
The set of Wavelength is absorbed by pigment. So in a typical leaf some pigment can’t be visible.
Explanation:
There are mainly three types of key pigments in photosynthesis. These three key pigments are Chlorophyll a, Chlorophyll b, and β-carotene. Those set of wavelengths which is not absorbed by pigment and finally it is reflected and that reflected light is what we see as a color.
The reason behind color of plant looking green because it contains huge amount of chlorophyll a and b molecule. It reflects the green light.
D because it makes more sense
