Which of the following is a reason why microbes were found to be problematic? they were found everywhere. they could cause infection. they killed specific bacteria. they did not respond to antibiotics.

I believe the answer is B.

Explanation:

Microbes could cause infectious diseases like for Ex: Flu and measles or heart diseases.

Hope my answer has helped you! :)

Microbes are found to be problematic for two reasons that they cause infection and sometime these organisms does not respond to antibiotics.

Explanation:

The microbes can cause infections in humans is a problem. Fungi, helminths and protozoans are the major cause of infectious diseases. Resistance to an antibiotic occurs when an ability to defeat drugs created to kill them are developed in a microbe. When a microbe becomes resistant, the antibiotics cannot fight against them and hence they multiply.  

Antibiotic resistance is an urgent threat to the health of the public. They become a threat, when a microbe become resistant to antibiotic and it will be very difficult to destroy them. The resistance to antibiotics can cause serious issues like disability or even cause death.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
