Answer:
A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.
Explanation:
Answer:
Molecules.
Explanation:
Molecules are the items that attach on the inside of the mineral to give the mineral its shape. The molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that, these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
The options are all related, and the answer is D) All of the Above.
The synergistic effects of exposure to multiple toxins are more difficult to quantify and study. As a result, there is not sufficient research on how much a system can take when exposed to multiple pollutants. This lack of research also means that we often do not even know what the effect of these interactions between multiple toxins are.
As a result of these gaps in our knowledge of the interactions between toxins, it is difficult to evaluate the threshold for pollutants, since a system will rarely feature only one pollutant in isolation.
