Answer:
B. In fishes, blood passes through the gills, returns to the heart, and then is pumped to the systemic tissues.
Explanation:
In fish, blood does not pass through the gills, returns to the heart and is then pumped into the systemic tissues.
Most fish breathe through gills. Water continually enters the fish's mouth, bathes the gills and exits through the openings on either side of the head. Most fish breathe through gills, also known as gills. Water continually enters the fish's mouth, bathes the gills and exits through the openings on either side of the head.
The heart of the fish has two cavities, an atrium and a ventricle - and through it only unoxygenated blood circulates. After passing through the heart, unoxygenated blood goes to an artery and into the gills where it receives oxygen gas. This now oxygenated blood is distributed to all organs of the animal's body.
Answer:terrestrial planet
Explanation:
Answer:
If a whole specie of organisms has to survive, they should must possess the ability to reproduce and adopt to environmental conditions in better way.
For example: If a disaster occurs or a condition of unfavorable weather occurs, the specie will survive even if only few members remain alive. Because those members will reproduce and regrow the community.
The reason is this that reproduction is not important for the survival of one organism, like organism will still survive even if he do not reproduce, but if a whole specie has to survive and continue, reproduction is most important trait.

Answer:
c. Proteins
Explanation:
A stretch of DNA that code for specific proteins is said to be a gene. A gene is transcribed into mRNA. The mRNA has a nucleotide sequence complementary to the corresponding gene. The nucleotide sequence of mRNA is read in the form of genetic codes during the process of protein synthesis to specify the amino acid sequence of proteins. Therefore, genes carry the genetic information for the assembly of proteins and the processes of transcription and translation deliver the stored genetic information.
