The smaller flashlight has less inertia than the larger flashlight, so it takes
less force to change the motion of the smaller flashlight.
Inertia is defined as the property of an object to resist changes in its velocity
when in motion. A larger or bigger body has more mass and inertia as it
requires more force to change the direction of the object.
The smaller flashlight has less inertia than the larger flashlight and hence
requires less force to change its motion due to its smaller size.

The correct answers are I and IV
There are three main effects of complement :
1. Lysis of cells such as bacteria and tumor cells.
2. Generation of mediators that participate in inflammation and attract neutrophils to the site of infection, an event called chemotaxis.
3. Opsonization i.e. enhancement of phagocytosis.
Lysis of pathogens by complement involves the insertion of a special substance called the membrane attack complex into the cell membrane of the pathogen which disrupts or punctures the membrane as a result of which water and electrolytes enter the pathogen and it dies.
Generation of mediators known as C5a and C567 complex attract neutrophils.
Answer:
e. bacteria producing vitamin K
Explanation:
Microbial antagonism basically refers as microbes versus microbes i-e the indigenous microflora serve a beneficial role by preventing other microbes from becoming established in or colonizing a particular anatomic location in the body.
As all the options mentioned, refers to the microbial antagonism except option E as the normal microbes protect the host by :
1) Producing acids.
2) Bactreocin production
3) By occupying the niches that the pathogens may occupy.
But the microbes cant compete with other microbes by producing vitamins and growth factors that can be utilized by the host.
Hence option E is the right answer.
On my work the answer was D ..
