Answer:
This is due to bio magnification.
Explanation:
When there is a gradual increase in concentration toxins(pesticides) in the tissues of organisms progressively in the food chain,the term for describing this is called -bio magnification.
The progressive multiplication in the concentration of these toxins may be due to non-biodegradable nature of the toxins,which are absorbed into the tissues of mostly the producers from the environment faster than they could metabolized by the body.
.Therefore these could not be removed by the producers, during excretion and respiration,and hence build up progressively upwards in the consumers.
A typical example is the phytoplankton which absorb toxins from sea water and accumulate this in the body.The build could not be ,metabolize by the body system,and is transferred to the zooplankton along the food chains when they feed on the phytoplanktons- this is Bio magnification.The main focus of conservation is to
a. wisely manage natural resources for people's use
b. set aside land and protect it from human activities
c. demand government action to pass environmental laws
d. prevent wild species from becoming endangered
e. limit society's demand for natural resources
Answer:
A.) Wisely manage natural resources for people's use
Explanation:
Because conservation is like preservation but conservation wants to seek sustainable use of nature by humans for activities such as, hunting, logging, and even mining.

what are several defenses that keep pathogens from getting inside the body
Answer:
The body has two lines of natural defense to protect against infection. The first are physical barriers, such as the skin, body secretions and mucous membranes. The second line of defense is the immune system. Specialized immune cells coordinate and execute attacks to kill germs that make it past the body's physical barriers.
Which renewable resource is not at risk?
1) Fisheries
2) Petroleum
3) Forest
4) Ground water
Answer:
C, forest.
Explanation:
Trees are easily replaceable. With the other options, those are all considered non renewable energy sources. Those take millions of years to form. When we look at fishery, people can do what's called "overfishing" when they fish too much faster than fish can reproduce. Therefore making C your best answer choice.

Answer:
The answer is A by repeating the experiment several times
Explanation:
i did it on edu
By repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).
What is an experiment?An experiment is defined as a procedure which is carried out to support or disprove a hypothesis. It determines the efficacy or potential of something previously unusable. It provides insight into cause and effect by demonstrating what results when a particular factor is manipulated.
An experiment is defined as a type of empirical study that involves manipulation of an independent variable, measurement of a dependent variable, and control of extraneous variables. This extraneous variable is any variable other than the independent and dependent variables.
The best approach when conducting a scientific experiment is to test repeatedly and make sure the experiment can be repeated.
Thus, by repeating an experiment many times, scientists increase confidence in the results. So, the correct option is (A).
