Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.

Which phrase does not describe a way the human body responds to fight disease?
(1) destruction of infectious agents by white blood cells
(2) production of antibodies by white blood cells
(3) increased production of white blood cells
(4) production of pathogens by white blood cells
Explanation:
Answer is option 4, PRODUCTION OF PATHOGENS BY WHITE BLOODS CELLS.
During the fight against diseases by human, the white blood cells otherwise called leukocytes are involved in the protection of the body against infectious agents and pathogens, do not produce more pathogens rather antibodies to fight against the invading pathogens.
There is increased production of white blood cells during infection by pathogens, the infectious agents are destroyed by the white blood cells and the production of antibodies against the pathogens.
Hello. You forgot to report that this question is about the "Eagle eye" article
Answer:
I had already heard about all the ecosystem services mentioned in the article and according to how the use of nature and exploitation has been taking over our society, all services receive my concern.
Explanation:
The "The Character of Ecosystem Services" section presents a series of ecosystem services that nature offers us and that are fundamental for the survival of human beings on earth. These services are: Production of Ecosystem Goods, Generation and Maintenance of Biodiversity, Climate and Life, Mitigation of Floods and Droughts, Services Supplied by Soil, Pollination, Natural Pest Control Services, Seed Dispersal, Aesthetic Beauty and Intellectual and Spiritual Stimulation.
These services are highly publicized in the media and there is no need for a long and time-consuming research to understand their importance in our lives and how we humans have failed to maintain them and caused them to be unavailable, through degrading exploitation and rampant pollution that has caused damage to nature and threatened our existence in the future. For this reason, all these services deserve our concern, in addition to deserving that all human beings change their habits to guarantee their existence and availability.
