Answer:
Gram positive bacteria are more resistant than gram negative bacteria to antimicrobials that disrupt plasma membranes because they have cell wall that is made up of a thick layer of peptidologlycan that contain teichoic and lipoteichoic acid to peptidoglycan.
Explanation:
Gram positive bacteria are bacteria that have thick wall made up of peptidoglycan and have no lipid membrane while gram negative bacteria are bacteria that have thin cell wall composed of peptidoglycan with lipid membrane.
Gram positive bacteria is resistant to antibiotics because of their thick cell wall composed of peptidoglylcan which contain teichoic and lipoteichoic acid , this help strengthen the plasma membranes and make them not to be attached by antimicrobial compared to gram negative that lack this.
Answer:
The correct answer is option C "The pressure change causes the organ of Corti to vibrate vertically".
Explanation:
The organ of Corti is an important structure for auditory perception that acts as a receptor organ for hearing. The organ of Corti is located in the mammalian cochlea and it allows for the transduction of auditory signals into nerve impulses according to the vibrations that are received from external sources. If the receiving sounds comes from the stapes pushing against membrane covering the oval window, the pressure change will causes the organ of Corti to vibrate vertically. Stimulus from membrane covering the oval window are sent to the organ of Corti, which responds by vibrating vertically.
The answer is A. I'm sure about this
Population decreases by 15.
Birth rate means more population (positive), death rate means less population (negative), immigration means more (positive), and emigration means less (negative). So, just add and subtract the appropriate numbers:

Negative 15 people means that the population decreases by 15.
