how does skin protect the body from pathogens?
A it produces whit blood cells that reconize and eat pathogens.
b it transsfers pathogens to lymph and blood plasma
c it traps pathogens in oil and seat produced by glands.
d. it has hairs that sweep pathogens away from the body
Answer:
C: It traps pathogens in oil and sweat
Explanation:
The skin has oil and sweat which kills pathogens as they are like a waterbarrier.
The skin protects the body from pathogens by trapping pathogens in oil and sweat produced by glands. Thus, the correct option for this question is C.
What are Pathogens?Pathogens may be defined as those living organisms which are capable of inducing diseases in other living organisms including humans. Some examples of pathogens include bacteria, fungi, protozoa, etc.
Skin is considered the first line of defense against pathogens in humans. This is because skin significantly consists of sebaceous and sweat glands that consistently secrete oils and sweat that trap the pathogens and eliminate them from entering the body.
Therefore, the skin protects the body from pathogens by trapping pathogens in oil and sweat produced by glands. Thus, the correct option for this question is C.

What is the total number of electrons in an atom of an element with an atomic number of 18 and a mass number
of 40?
a. 58
c. 22
b. 18
d. 40
Answer:
18
Explanation:
In neutral atom protons and electrons are equal in number as it atomic number or proton number is 18 so electrons are also 18
The total number of electrons in an atom of an element with an atomic number of 18 and a mass number of 40 is 18.
What are the difference between atomic number and atomic mass ?Atomic mass can be defined as the total number of neutrons and protons located in nucleus of an element while atomic number is the number of protons present in the nucleus of element.
Atomic mass can be defined as the average weight of an element where as the atomic number is the total number of protons present in the nucleus; Atomic mass have the symbol A while atomic number have the symbol the letter Z.
Different isotopes of an element are differentiated by atomic mass is while isotopes share the same atomic number, in neutral atom protons and electrons are equal to atomic number or proton number is 18 and electrons are also 18
