A cell which contains cytoplasm, cell membrane and a nucleus
Explanation:
The watermelon fruit when is covered by the molds, a type of fungus which can grow on the moistened substances. The molds can be characterized by their black, green and white spores.
The molds grow on the moistened surface by growing their hyphae which can form mycelium. These hyphae continuously produce enzymes which can breakdown the organic matter present in the watermelon.
Therefore, the matter and energy of the watermelon are transferred to the molds as it forms the next trophic level in the food chain.
The correct answers are:
1.) Older crust is melted at subduction zones;
2.) Oceanic crust is created at mid-ocean ridges;
The places were the tectonic plates are moving away from one another open up a gap between them, making the crust much thinner, thus enabling the magma from the mantle to easily penetrate upwards and rise towards the ocean floor. When the magma reaches the ocean floor it is cooling off very quickly, creating new crust, and giving rise to the mid-ocean ridges.
On the other side, on the convergent plate boundaries, where one plate subducts bellow the other, the crust from one of the plates goes bellow the other one. As it goes bellow it, it reaches the mantle. Because the mantle is very hot and has high pressures, the crust is melted.
