I would say D it seem to be the likely choice but not a 100%
Answer:
Mass does not affect gravity and distance has an indirect relationship.
Explanation:
The equation for gravity is, g = 
where, G = gravitational constant
M = mass of the planet
R = distance between the bodies (object and center of planet)
so, gravity depends on the mass of planet, not on mass of object
and is inversely proportional to sqaure of distance.
Directly The immune system is designed to defend the body against foreign or dangerous invaders. Such invaders include
Microorganisms (commonly called germs, such as bacteria, viruses, and fungi)
Parasites (such as worms)
Cancer cells
Transplanted organs and tissues
To defend the body against these invaders, the immune system must be able to distinguish between
What belongs in the body (self)
What does not (nonself or foreign) normal immune response consists of the following:
Recognizing a potentially harmful foreign antigen
Activating and mobilizing forces to defend against it
Attacking it
Controlling and ending the attack
If the immune system malfunctions and mistakes self for nonself, it may attack the body’s own tissues, causing an autoimmune disorder, such as rheumatoid arthritis, Hashimoto thyroiditis, or systemic lupus erythematosus (lupus).
Answer:
Tertiary Structure
Explanation:
Proteins are made up of amino acid units. The four types of protein structure are primary, secondary, tertiary, and quaternary.
From the given options, the greatest effect on a protein's function is caused by tertiary structure because it has branched structure and have several side chains. These side chains can interact in different ways and can change the effect on a protein's function.
Hence, the correct answer is "Tertiary Structure".
