Answer:
Animals at the top of the food chain are too hard to be caught and eaten, while plants and smaller animals are eaten easily.
Explanation:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
D) species
To figure this out think of the order in which you classify organisms in. Domain, kingdom, phylum, class, order, family, genus, species (in the order from most diverse to least)
The isopropanol will extract the DNA from the strawberries.
Explanation:
Strawberries help in DNA extraction as it has enzymes and pulverizes easily which breaks the cell wall and has large number of DNA in it. The isopropanol helps in precipitating the DNA.
In an experiment of DNA isolation, a squashed and refrigerated strawberry was added in a isopropanol solution after filtering it. It can be seen DNAs are starting to isolate from the strawberry extract in the form of fluffy bubbles.
