They mess up local ecosystem and if not eradicated they can take over the ecosystem. Example: pythons in the Florida Everglades. These snakes were released in the wild and they not only survived but flourished in this environment eating small animals in the glades and if that animal say frog gets eraticated the species above the food chain will die off from that area so on and so on

VARVARA [1.3K]

The right answer is A.

Insecticides are active substances or phytosanitary preparations with the property of killing insects, their larvae and / or their eggs. They are part of the family of pesticides, themselves included in the family of biocides, both of which are regulated in Europe by specific directives.

Some pestiids such as organoclorides are broad-spectrum, ie they act on several insects at the same time (whether they are good or bad).

An example of a false negative is taking an HIV test and having the test come back negative to say the patient is clean, but in reality they have HIV. Another example of a false negative is a woman taking a pregnancy test saying "not pregnant" (i.e. test is negative), but she actually is pregnant. Between those two examples, it is better to have a false negative pregnancy test because it is non life threatening.

A false positive example would be getting bad news you have cancer, when you actually don't have cancer. Another false positive example is a test saying you have a cold virus, when in actuality you don't. The first example mentioned would have the patient likely go through intense chemo treatments which would greatly affect their livelihood. The second example is a more harmless false positive as it would involve at most a flu shot if anything.

An ecosystem has 150 organisms of 15 different species. What is the biodiversity index of this ecosystem?
iren2701 [21]

Answer:

0.1

Explanation:

To calculate this, scientists use a formula called the biodiversity index in order to describe how much are the species of a given area diverse. It is calculated by taking the number of species in the area and divided by the total number of individuals in that area. This gives us the biodiversity index.

In this example, there are 15 species in an area and we divide that by 150 organisms to get a 0.1 biodiversity index.
