S. aureus is gram positive. What differences in strains might account for differences in phage susceptibilities?
S. aureus is indeed gram-positive but within the bacteria classed as gram-positive, there are differences that might predispose them to infection by phages.
S. aureus as an organism usually adapts to their environment through mutations on their membranes which can be proteins e.g. surface proteins, or receptor molecules e.g. sugar receptors.
In preventing invasion by phages, mutations are gained that prevents attachment to the bacteria cell surface. This effectively prevents the binding of the phage to the bacteria thus preventing infection.
It is also worthy to note that the differences in bacteria strain could range from a few nucleotides to large variations in chromosomes and thus can aid in identifying specific strains that might have beneficial factors in the context of disease prevention.

What processes have destroyed most of the remnants of earths earliest formation
Answer:
volcanic eruptions
Explanation:
most of the energy that your brain uses comes from
Answer:
Glucose
Explanation:
The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.
Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.
Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.
The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.
Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.
When is the kinetic energy of a pendulum the least?
Question 5 options:
On the path beginning the upwards swing.
Half the distance on the path traveling back down.
At the bottom of the swing.
At the top of the swing where it briefly stops before changing direction.
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The Correct choice is ~
" At the top of the swing where it briefly stops before changing direction "
before changing the direction, it stops for a while therefore the kinetics energy is almost zero at that particular moment ~
The answer is D - At the top of the swing where it briefly stops before changing direction. This is where potential energy is at its highest, meaning that kinetic energy is at its lowest. When the pendulum is beginning its upwards swing, it has a lot of kinetic energy. When it is half the distance traveling down it also has lots kinetic energy. When it is at the bottom it as well has a lot of kinetic energy. The only time where the kinetic energy is least is when the pendulum stops to change direction. Any form of stopping forced the object to loose its kinetic energy.
