Cell Structure And Infectious Sales Flashcards
What is the difference between an infectious disease and a non-infectious disease?
Infectious can be spread from person to person and noninfectious cannot be spread
How are the following pathogens most often spread from organism to organism? Virus, fungus, bacteria, protist
Virus: inhaling contaminated air, touch of contaminated object, coming in contact with contaminated person, exchange of bodily fluids
Fungus: inhaling spores, or spores landing on your skin
Bacteria colon and hailing contaminated air, biological vectors, contaminated objects, coming in contact with contaminated person
Protist: contaminated food or water, Bala
What is the difference between an antibiotic and a vaccine?
Vaccines are weaken forms of a live virus/bacteria that creates an immune response that fights off the infection when the actual virus/bacteria enter your body, antibiotics weekend or kill bacteria only
What does it mean that the cell membrane is selectively permeable?
The cell membrane allows certain materials to leave and enter the cell
Explain how plant and animal cells are different?
Plant cells have a larger vacuole, cell wall, and chloroplast for photosynthesis
List the ways you can prevent an infection from a pathogen.
Wash hands, exercise, get rest, eat healthy, get check ups, stay away from contaminated people
Describe how a virus infects the body.
Attaches to the cell membrane, injects genetic material, duplicates until the cell burst and dies, newly replicated virus attack other cells
What is a biological vector give an example
An organism that carries a disease that can be passed to humans. Example malaria is carried by mosquitoes
What is the negative effect of over using antibiotics?
Bacteria becomes resistant to antibiotics can be spread to other individuals and make the antibiotic and
What are some positive ways that the following organisms can help in the environment or in industries
Bacteria: healthy digestive systems production of dairy products (cheese, yogurt), oxygen for the environment, insulin production for diabetic patients
Fungus: mold: used to make certain the anabiotic’s yeast: used to make bread’s and alcohol from ferry
In the equation, P4+02 equals P203, if there are 20 g of pay for and 15 g of O2 how many grams of P2O3will form?
35g
List grapes on the periodic table will ionically bonded together.
Great 16 ionically bonds with group 2, group one ionically bonds with group 17
Name three gases that contribute to the greenhouse effect what is AC current used instead of DC in the power grid?
AC current can travel from high to low voltage is and it can change directions
If you push a skateboard that has a mass of 60 kg with a force of 6N what force will the skateboard pushback on you according to newtons third law of motion?
6N
If two objects have different masses which object is easier to accelerate? Which law supports your answer?
The smaller mass
The tendency of an object to resist a change in its motion is known as ?
Inertia
Newtons first law of motion states that an object remains at rest unless a —— force acts on it
Unbalanced
The statement for every action, there is an equal but opposite reaction is a statement of?
Newtons third law
When a swimmer pushes the water back, the water pushes the swimmer forward. What is the reaction force to in this situation?
Water push the swimmer forward
Gel like material that fills the cell and surrounds the organelles
Cytoplasm
Allows materials to enter or exit the cell and protects the contents of the cell
Cell membrane
Control center of the cell
Nucleus
Transport materials and proteins around the cell
Endoplasmic reticulum
Build proteins in the cell
Ribosomes
Provides energy for the cell by breaking down sugar molecules in cellular respiration
Mitochondria
Provides food for a plant cell if I collecting energy from the sun during photosynthesis
Chloroplast
Rigid material that surrounds a plant sale that gives that shape support and protection
Cell wall
