Answer:
Food chains are a pictorial description of an ecosystem: what eats what. This helps scientists track the web of interdependence. If one important component in a chain is removed or affected, we can make predictions about how this might impact the entire ecosystem. We can track the effects of disruptions on a system.
The correct answer is the second option. Animals have two major types: vertebrates and invertebrates. Vertebrates are animals that have backbone while the invertebrates do not have one. Examples for vertebrates are birds and mammals while the latter are insects and squid.
Answer:
B. Position B
Explanation:
The values for dependent variable are plotted on the y-axis (vertical) on a scatter plot. Therefore, the label for the dependent variable would be written along the vertical axis for the scatter plot, at position B.
The label for independent variable would be written along the horizontal axis for the scatter plot, at position C.
The answer is "B. Position B"
<span>Since muscle contraction depends on interactions between actin, myosion and some intermediate molecules, the primary protein structure of such proteins and their spatial conformation are fundamental for their functioning. For example, actin and myosin, both filamentous proteins that slide past each other or troponin/tropomyosin interactions that blocks the binding of myosin to actin.</span>
