Based on the diagram, what conclusion can you make about the shark’s growth and development?A) Sharks undergo a metamorphosis in their life cycle.
B) Sharks have an immature, inactive stage.
C) Sharks have a simple life cycle.
D) Sharks form lungs later in life.
E) A newborn shark looks different from an adult shark.
Answers
Answer: Option C
Explanation:
Sharks have a very simple life cycle. The eggs are produced from a pregnant shark.
The baby sharks comes out of the eggs and then they start growing into young ones.
These young ones divide and forms an adult shark. This is very normal and simple as like that of other organism, there is no intermediate stage in the life cycle of the shark.

Answers
What happens to the oil when you first pour it in? It flows into the water, but then seperates.
Why does this happen? oil is lighter than water and the molecules of the oil are attracted to the other oil molecules, not water, the water molecules the same
What kinds of animals would be most affected by an oil spill at the beginning? animals that live their lives near the surface of the ocean. Why? because now the water that was clear and free-flowing is now dark and sticky. oil also changes the way how some animals survive so make their ways less effective. one example are birds like pelicans
Use a spoon to stir the oil for 30 seconds.
Answer the following questions:
What natural action stirs the real ocean? ocean currents caused by wind and the earth's roation
What happened to the oil? went back to the top
Even if you can’t see it, is all the oil still in your ocean? yes
Which animals in the ocean become affected after wave and currentaction causes some of the oil to settle to the bottom, or be absorbedinto the water? bottom-feeders
Add a splash of dish detergent to the mixture and stir.
Answer the following questions:
What happened to the oil? it mixed with the water Is it all still in the ocean? yes
Sometimes cleanup efforts involve dumping a soap mixture over a spill area. Why is this done? to bond the oil to the detergent and the detergent to the water. so they can grab all the oil
What might be a negative effect of dumping the soap? soap has chemicals that could upset the ballance of the ecosystem and kil some animals/plants

Final answer:
All lipids are hydrophobic, meaning they do not dissolve in water. This results from their predominantly nonpolar carbon-carbon and carbon-hydrogen bonds.
Explanation:
All lipids, which are a type of macromolecule, share one fundamental attribute: they are hydrophobic, meaning they do not dissolve in water. Instead, lipids tend to cluster together when in a water-based environment. This hydrophobic quality results from the predominantly nonpolar carbon-carbon and carbon-hydrogen bonds that make up most of a lipid's structure. Other examples of lipids include fats, oils, and waxes.
