Answer:
<em>The correct option is C) direction of force</em>
Explanation:
In the terms of physics, force can be described as a push or pull on an object which allows the object to either move forward or backwards or in other directions.
When Dr. Jeff uses the fire extinguisher of the skateboard to move forward, he will require the same force to move backward but in the opposite direction. Hence, for moving backwards, the only thing required by Dr. Jeff to move backwards will be the direction of the force.
The complement system will work first in the given scenario of Staphylococcus aureus infection, i.e., option A.
<h3>What is a complement system?</h3>
The complement system, also known as the complement cascade, is an immune system component that improves (complements) antibodies' and phagocytic cells' ability to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.
In the given scenario, when Staphylococcus aureus enter the body through an injury or broken skin, and get into the bloodstream then the complement system initiate the phagocytosis.
Thus, the correct option is A.

Answer:
Increase in biomass
Explanation:
All the other choices have attributes that influence the density property of water except biomass. Biomass is organic material/ matter that is mainly carbon-based – mainly derived from plants and animals. This has no relationship to water density even when the biomass is in the water because it's only gets suspended like sediment and does not get dissolved in the water.
Answer:
Energy flow through ecosystems begins with producers. Chemical energy flow begins with consumers who obtain chemical energy by feeding on producers.
Explanation:
by dehydration synthesis
Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds between monosaccharides. A dehydration synthesis reaction forms a bond between carbon atoms in two monosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.
