Answer:
Explanation:
Water washed disease are diseased that occur due to lack of water for proper personal use.
Often common in areas with predominantly poor people.
Water borne diseases are disease that are are transmitted by pathogens and micro organisms in water. Bacteria and protozoan are major carriers of water borne disease. When exposes to contaminated water one could get the disease from there.
Both water borne and water washed diseased are characterized by pathogens and micro organism.
They both result in serious medical condition that requires treatment via drug administration.
Lack of proper hygiene can result in both water washed and water borne disease.
Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.
Hope this helped!
The correct answer would be A. seal as paramecium, bacterium, and amoeba are all single-celled organisms. Thus, they cannot be an organism with tissues.
