Bony fish belong to Class Osteichthyes, while cartilaginous fish belong to Class Chondrichthyes. Bony fish have a bony skeleton, while cartilaginous fish have one composed mostly of cartilage. Bony fish have body coverings of scales, while cartilaginous fish are covered with dendritical projections (think shark skin).
Bony fish are found in fresh and salt water; cartilaginous fish are found only in salt water. Bony fish have gills covered by an operculum; cartilaginous fish have gill slits. Bony have no eyelids; the cartilaginous fish do. Bony fish have an air-filled swim bladder; cartilaginous fish have an oil-filled liver to keep them bouyant. Hope this helps! Whew!
One natural disaster has the ability to wipe out large crops and buildings that were used to fuel Earth's economy. It can also lead to a lack of biodiversity of an area that experienced the disaster.
For example, a tsunami can destroy buildings and kill an abundance of wildlife.

The complementary sequence of nucleotides found on the other strand of DNA is <u>ACGAAT</u> when one strand in a segment of a gene has the base sequence TGCTTA.
<u>Explanation:</u>
Deoxyribonucleic acid is the one which carries the genetic information from the parent to the offspring. During DNA replication one strand of DNA replicates to produce another strand.
The DNA molecule have a anti-parallel structure and the two strands run in opposite direction. If in one strand in a segment of a gene has the base sequence TGCTTA the complementary sequence of nucleotides found on the other strand of DNA will be ACGAAT.
Answer:
How does carbon dioxide affect orca?
Image result for Carbon dioxide Direct effect on orca
Once those waters return to the ocean floor, they can take with them large amounts of carbon dioxide, sequestering the gas away for hundreds or thousands of years
