<h2><em>
Streptococcus pyogenes</em></h2>
Explanation:
On looking through the microscope we will see purple, spherical-shaped organisms arranged in chainlike formations.
The reasons are:
- Streptococcus pyrogenes is a gram positive bacteria and hence it will take up Gram's stain and appear purple in color.
- Streptococci are colonial bacteria that are spherical in structure arranged in chain like formations.
<em>Streptococcus pyogenes </em>usually inhabit the skin of humans and are causative organisms of several infections such as tonsilitis, pharyngitis cellulitis, dermal infections etc.
Your heart has to work hard to pump more blood during exercise for each contraction, accounting for the increase in the systolic blood pressure. Diastolic pressure tends to not change at all or change slightly. The reason for this is that since the blood flow is increased during exercise, our arteries dilate, making the diastolic pressure stay the <span>same, or decrease slightly.</span>

The integumentary system (skin) reacts different on different sun intensity (different length exposure to sun).
For example, moderate exposure to the sunlight contributes to the production of melanin and vitamin D by the body. On the other hand, high exposure to sunlight can have negative health effects such as sunburn, which is an inflammatory response to DNA damage caused by UV radiation.
