Marine debris is defined as any man-made solid material that goes into waterways either directly or indirectly. Eighty percent of the marine debris comes from the land-based sources. Examples of marine debris are soda cans, plastic bag, cigarette waste. Anything that ends up in a water body that has a potential in harming the marine life is a marine debris.
Answer:
2. Hip bones
Explanation:
More than 40 million years ago, whales had ancestors who walked on land. Even now, they have a feature they inherited from them - hip bones. Scientists used to think that they are vestigial, i.e. that they lost their function. However, recently they discovered that these bones help whales (and other marine mammals who have them, such as dolphins) maneuver better mating.
Whales developed the rest of the listed features later, when they became marine animals. This is why they are incorrect.
Answer:
the is no anser bicos the is not a question
Answer:
The G-note's wavelength is longer.
Explanation:
As we know that
The relationship between frequency, wavelength and the speed given as
Speed = Frequency x Wavelength
V= f λ
For constant speed, if wavelength increase then the frequency of the sound get reduce.
The wavelength of the A-note sound waves is smaller than the G -notes sound waves.
Therefore the answer of the given question will be A.
The answer is A.They contain different genes
