Answer:
Animals most likely pollinate by accident.
Explanation:
Deer for example, they may graze in the grass. The pollen/seeds could catch onto their fur--and later fall off into a different area when they walk away. They could also eat a plant, and the seeds end up in their feces. Bees for another example don't necessarily <em>mean</em> to pollinate, they just happen to pick up pollen/seeds when they land on a flower for honey.

During translation, a ribosome reads a sequence of mRNA (messenger RNA) in groups of 3 bases called codons. The ribosome then calls for a tRNA (transfer RNA) molecule with another group of 3 bases that correspond to the codon. This group of bases is called an anticodon. The ribosome strings the anticodons together to create an amino acid chain, and then final processing occurs to create the desired protein. In a way, the ribosome is translating the language the mRNA is using into a language that the tRNA can understand, hence why translation is used.
Answer:
Flatworms are small, literally flat worms, which 'breathe' through diffusion across the outer membrane (Figure 2). The flat shape of these organisms increases the surface area for diffusion, ensuring that each cell within the body is close to the outer membrane surface and has access to oxygen.

Answer:
A. Water is denser and more viscous than air.
B. Water contains much less O2 than air per unit volume.
E. Diffusion occurs more slowly in water than in air.
Explanation:
The gas exchange for aquatic animals is more difficult than for terrestrial animal because of several reasons like water is denser and vicious than air so the diffusion of oxygen in air is much faster than the diffusion of oxygen in the water.
The concentration of oxygen in the air is much higher than the concentration in the water. In air the concentration of oxygen in 21% but in water, it is a tiny fraction of 1 percent oxygen. The oxygen holding capacity of warm water becomes less in cold water. So the right answer is A, B, and E.
Number 2 because they are still developing
