B. Cells are found in all organisms
C. Cells are sometimes specialized for particular functions
D. All of the above
Answer: B
Explanation:
Ammonia is so toxic that it can be transported and excreted only in large volumes of very dilute solution. As a result most terrestrial animals simply don't have access to sufficient water to routine excrete ammonia.
The main advantage of urea is its very low toxicity. Animals can transport urea in the circulatory system and store it safely in high concentrations. Also much less water is loss when a given quantity of nitrogen is excreted in a concentrated solution of urea than would be in a dilute solution of ammonia.
Seedless plants genetically alternate between generations.
<h3>What is the reproduction cycle of seedless plants like?</h3>
All seedless vascular plants have very similar life cycles. As in bryophytes, their life cycle has two alternating generations:
- the gametophyte
- and the sporophyte.
- The sporophyte is always the dominant and free-living generation.
With this information, we can conclude that seedless plants genetically alternate between generations.
