ANSWERS PASSED 100% UPDATED
VERSION
Structure of a typical viral particle? - Correct Answer ✔✔ -nucleic acid with either DNA
or RNA
-surronder by a capsized of protein
-sometimes embellishments (a viral envelope outside the capsid)
How do viruses infect cells? - Correct Answer ✔✔ attach themselves to the host cell
-by injection of their nucleic acid into the host cell
-by the host cell engulfing the virus
Why is a virus considered "not" alive? - Correct Answer ✔✔ -they lack the ability to
reproduce/replicate
-so it is highjacking the cellular machinery inside the host cell to make its own protein
-acellular, and parasitic
-don't grow and divide on own
Different types of innate immunity? - Correct Answer ✔✔ -skin
hair
cilia
-mucus membranes
-digestive enzymes
-stomach acidity
-inflammatory response
inflammatory response? - Correct Answer ✔✔ -inflammation
-a response to trauma
-bacteria,fungal spores and/or viruses have a direct entry into your circulatory system
How pathogens are marked and destroyed when they invade the body? - Correct
Answer ✔✔ -antibodies search for them in blood and breast milk and mark and destroy
them by phagocytes before they can infect cells
-the more antibodies the higher the response to the invaders
How vaccinations can cause secondary response? - Correct Answer ✔✔ -put a small
amount of the pathogen in you which creates memory cells or antibodies to kill it off it
returns
, How herd immunity works? - Correct Answer ✔✔ -indirect form of protection from the
infectious disease that occurs when a large percent of a population has become
immune to the infection
Why everyone who is medically capable should get vaccinated? - Correct Answer ✔✔ -
vaccinations have to be at 95% of people or above in order for a disease to disappear
-not enough people are vaccinated to keep the diseases away
How fats are digested? - Correct Answer ✔✔ -most fats have a long chain of carbons
with hydrogen atoms attached, digested by enzymes breaking the carbon bonds
How proteins are digested? - Correct Answer ✔✔ -enzymes cleaving off amino acids
from the larger protein molecules
How carbohydrates are digested? - Correct Answer ✔✔ -enzymes cleaving off simple
sugars from larger carb molecules
What causes type 2 diabetes and how it can be prevented? - Correct Answer ✔✔ -
insulin resistance
-insufficient insulin production by the pancreas
-prevented by lowering the sugar taken in
-maintaining a healthy weight
-exercising at least 30 min/day
Consequences of obesity? - Correct Answer ✔✔ -heart disease, stroke, type 2
diabetes, cancer
-leading cause of preventable death
Structures of digestive system? - Correct Answer ✔✔ -mouth
-pharynx
-esophagus
-stomach
-small intestine
-liver
-gall bladder
-pancreas
-large intestine
Function of the mouth? - Correct Answer ✔✔ -the first portion of the alimentary canal
that receives food and produces saliva
Function of the pharynx? - Correct Answer ✔✔ -the membrane-lined cavity behind the
nose and mouth, connecting them to the esophagus
Function of the esophagus? - Correct Answer ✔✔ -a muscular tube connecting the
throat (pharynx) with the stomach
