Hey there!
Here are your answers:
<u><em>1. The proper answer to this question is "the Sun".</em></u>
Reason:
<u><em>The Sun is the ultimate source of energy for organisms it allows plants to use photosynthesis </em></u><span><u><em>to convert light energy into energy for that organisms and other organisms.</em></u>
<em>Therefore the answer is the Sun.</em>
Here is your second answer:
<u><em>2. The proper answer to this question is "</em></u></span><u><em>photosynthesis".</em></u>
Reason:
<u><em>Photosynthesis is the process that plants use to change (convert) light energy into energy (that other organisms can use). For example a apple tree uses </em></u><span><u><em>photosynthesis to make apples for humans, and other organisms to consume for energy.</em></u>
<em>Therefore the answer is </em></span><span><em>photosynthesis!</em>
<em>To sum up the answers are:</em>

The right answer is D.
The absorption of molecules at the level of the skin is carried out by passive diffusion for the molecules of low molecular weight (lower than 400 Da), the skin being covered with a lipoprotein film rich in water by its stratum corneum, rendering it little-permeable.
This absorption may be variable according to factors related to the skin such as stratum corneum's thickness, the state of hydration, the presence of cutaneous lesions or individual variations.
External factors may also modulate percutaneous absorption such as contact time, iontophoresis or the presence of specific adjuvants.
Answer:
True
Explanation:
Sewage contains many substances in it like suspended solids, organic and inorganic impurities, nutrients, saprotrophic and disease causing bacteria and other microbes. Hence it is said to be a complex mixture.
