Changing their properties by breaking bonds or forming bonds.
The answer is B. A eukaryotic cell's nucleus contains the DNA or the genetic material of the cell. The DNA has the necessary information for the cell's construction and the control of the synthesis tasks done by the cell. The nucleus is protected by the nuclear membrane. It surrounds the nucleus with a membrane with many pores.

Answer:
Among Sponges and Cnidarians, the difference among given facts is in "Have a network of nerve cells".
Explanation:
Both Sponges and Cnidarians have pores, they reproduce by buddings, and they live in freshwater. The major difference in both organisms is that: cnidarians have very simple nervous system made of sensory nerves that are arranged in the form of neural network. On the other hand, sponges are simple multicellular organisms without any neural network at all. In fact, they are the only multicellular organisms (animals) without a nervous system.
Answer:
Toucans disperse seeds of key forest species such as juçara palms by eating the fruit and defecating the seeds in new locations, sometimes more than a kilometer away. If there are no toucans, is the genetic diversity of palms likely to increase or decrease within forest fragments (and why)?
The genetic diversity of palm will totally decrease as a result of absence of Toucans dispersal of palms seeds which would not allow the seeds to be randomly grown anywhere. Dispersal has great impact on biodiversity of fruits because it enables the distribution of seeds to be grown everywhere
