The bacterial species Staphylococcus aureus is found on the skin and in the nasal passages of about 20% of the human population.

In healthy individuals, S. aureus is benign (does not cause harm) in these locations. However, if it is introduced into the bloodstream through, for example, a wound, it can make a person gravely ill. Thus, the ecological relationship of S. aureus with a human:______________

Answer:

The ecological relationship of Staphylococcus aureus with a human can be  mutualistic or antagonistic.

Explanation:

Mutualism is a type of ecological interaction. It occurs between 2 individuals in which each individual has a net benefit.

Antagonism is the opposite of Mutualism. It also occurs between two individuals but in this case one specie is getting the advantage at the  expense of the other specie.

A particular type of cell doubles in number every hour. Write the function that can be used to find the number of cells present
Orlov [11]

The function to represent the number of cells present at the end of h hours if there are initially 4 of these cells is n= 4(2)ˣ

Given,

A particular type of cell doubles in number every hour.

So, to determine which function can be used to find the number of cells present at the end of h hours if there are initially 4 of these cells.

The number of cells denoted with n.

Therefore, the number of bacteria after every hour will form a geometric series.

<h3>What is Geometric Progression?</h3>

Geometric Progression or geometric Sum of G.P. is refer to as if each term is a multiple of the next term then this sequence.  

aₙ =arˣ

Where a is the first term which is 4.

And r is the common ratio r = 2.

Therefore,

The number of cells present at the end of h hours if there are initially 4 of these cells is,

n = arˣ

n = 4(2)ˣ

Hence, the function represents the number of cells present at the end of h hours if there are initially 4 of these cells is n = 4(2)ˣ.
