Answer:
Out of, shrink
Explanation:
Water would move outside the cell due to osmosis. Osmosis is the movement of a solvent, water, in this case through a membrane from a region of high concetration to a region with less concentration .
The water molecules would move through the semi-pearmeable membrane from the region of high concentration (the bag) to a region with less concentration (the cup), thus, <u>equalizing the water concentration inside and outside the bag</u>. Since there is a higher concentration of salt outside, water will move out of the bag to equalize the concentration.
The result of this water movement would be an incurred bag or cell, hence, the cell would shrink.
Answer:
B. Many members of a key species, and the ecosystem will no longer be stable.
Explanation:
An ecosystem that contains a high degree of biodiversity will have numerous organisms of different species. According to the question, sharks are stated to feed on a wide variety of prey. This means that sharks can feed on any other species of organisms at lower trophic levels.
In a situation whereby an ecosystem contains a low degree of biodiversity i.e. low variety of species, the sharks will have to consume a large numbers of a key species, which will cause the ecosystem to lose stability.
Answer:
Igneous rock.
Explanation:
Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground.
The answer is bonds between atoms break and new bonds form. In order for a chemical change to happen, a new substance/substances (products) have to form that have different properties from the reactants. The bonds in the reactants break and new bonds form in the products.
