Your answer is B.
Sharks belong to a class of fish called "chondrichthyes" (means "cartilage fish") characterized by being jawed fish with skeletons made of cartilage instead of bone.
Sharks and fish with bones (osteichthyes) both have gill slits, scales and paired appendages. So, that would rule out the other answer choices.
Hope that helps!
Answer:
secondary succession
Explanation:
secondary succession occurs after a major natural disturbance in the environment, but the soil is still there afterwards so its faster then primary.
Answer:
The two forms interbreed and their offspring survive and reproduce well.
Explanation:
When talking about classification of species, one of the first features observed is the species fitness, which describes the reproductive success or their ability to leave to their successive generations the most copies of their genotype. When different species that were recently divided into 2, by geographic isolation, for instance, usually there is no genetic compatibility, and if its possible to produce offspring, there might be some development issues like infertility.
Explanation:
A Venn diagram is a diagram used to compare and show the similarity between more than two variables.
In the given question, the Venn diagram of carbohydrates and proteins has not been provided but the similarities and unique feature between them can be explained.
The similar features are:
1. Both are considered macromolecules.
2. Both are biomolecules used as energy molecules by body
3. Both perform various roles in the body like involved in the structural entity.
4. Both can be involved in body repair.
Unique features of Proteins and Carbohydrates:
1. Proteins act as cellular signalling molecules can act as an enzyme.
2. Carbohydrates act as a storage molecule by an organism like in the form of glycogen in animals and starch in plants.
