The correct option is INTRODUCTION OF EXOTIC SPECIES;
Exotic species refers to an introduced specie of an animal which is alien to the ecosystem in which it found itself and which has been transported to that ecosystem either intentionally or by accident. Exotic species normally have varieties of effects on the ecosystem to which they are introduced, sometimes the effect will be good and sometimes the effects could be devastating depending on the particular situation.
Factors which promote diversity include: larger size of the ecosystem, longer growing seasons and climatic stability.<span />
The correct answers are a, c, d.
There are three types of capillaries: continuous, sinusoidal (or discontinuous) and fenestrated. Continuous capillaries are the most common type and they form tight junctions. Sinusoidal capillaries form an incomplete lining with several gaps, which allow red and white blood cells and some serum proteins to pass. These capillaries are mainly found in the bone marrow, lymph nodes and adrenal glands. Finally, fenestrated capillaries facilitate the movement of smaller molecules and plasma proteins and are mainly found in the small intestine. The majority of the fluid transport happens through the fenestrated capillaries.
Answer:
the shadows are called umbra and penumbra
Answer:
The lower limit is 0.65°C
The upper limit is 1.05°C
the average is 0.85°C
The difference between the average and the lower limit is:
0.85°C - 0.65°C = 0.20°C
the difference between th average and the upper limit is:
0.85°C - 1.05°C = -0.20°C
Then we can write the change in temperature as:
T = 0.85°C ± 0.20°C
Now we want to find the error bar.
The error bar would be the total distance between the lowest value and the largest value.
Then the error bar is:
1.05°C - 0.65°C = 0.40°C
notice that the error bar is twice the error, which makes a lot of sense because the error (± 0.20°C) goes up and down.
Then the error bar in this measure has a magnitude of 0.40°C.
