Explanation:
Worms are invertebrate animals with bilateral symmetry. Worms have a definite anterior (head) end and a posterior (tail) end. The ventral surface of worms and other organisms is the bottom side of the body, often closest to the ground. The dorsal surface is located on the upper part of the body facing the sky. The lateral surfaces are found on the left and right sides of the body. Figure 3.35 compares bilateral symmetry in a whale shark and a swimming plychaete worm. Organs for sensing light, touch, and smell are concentrated in the heads of worms. They can detect the kinds of environment they encounter by moving in the anterior direction
Answer:
abiogenesis
Explanation:
a (not) biogenesis (coming from other life forms)
Biogenesis would mean that it's coming from other life forms,
Natural selection is a part of evolution (what is there to select?)
Variation is also a part of evolution (not related)
<span>The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which stored in the bonds of glucose.
</span><span>Photosynthesis transforms light into chemical energy that is stored in the form of ATP inside plants. Therefore, it is an energy storage process.
Bye!

Because it is polar and it is to large to cross the membrane and because the concentration gradients are to strong so they have to be diffused.
