Answer: 6,000/30 = 200, so 200 molecules are required.
Explanation:
First answer is correct. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.
In homo sapiens(humans), males are the heterogametic sex meaning their sex chromosomes are not the same(=XY) while females are homogametic(=XX).
Sex linked traits or x linked traits are traits whose genes are present on the X chromosome. So if there is a recessive mutation in those genes, males will express that recessive trait. Basically males express everything that’s on their X chromosome because they only have 1, but females have 2 which helps “hide” the mutation and to not express the particular recessive trait.
That is why sex linked traits are more evident in males in the population and an example of that would be colorblindness.
Hope this helps:)
Answer:
Explanation:
Approximately 70% of Earth's surface is covered in ocean water. When water at the ocean's surface is heated by the Sun it gains energy. With enough energy, the molecules of liquid water change into water vapor and move into the air. This process is called evaporation.
The correct answer is option B- sea anemone
Sea anemone belongs to group of marine animals, predator in nature. They belong to the phylum Cnidaria
Sea anemone has a foot like structure at the bottom which helps in attachment with rocks or anchor in sand but most of the species come near to the surface and float at the surface of water.
The most important and interesting factor about anemone is the presence of small tentacles around the mouth used to capture the prey.
