A protective layer that shields the surface from lethal ultraviolet light is found in the layer of the atmosphere known as the Stratosphere.
Therefore, the correct answer is option C for this specific statement.<span />
The correct answer is: 2- Hypertension, or high blood pressure
Hypertension leads to heart failure. Also, as a result of hypertension body tends to retain fluid in order to maintain adequate blood volume. A failing heart is unable to handle that extra fluid, so it is transferred out of the blood vessels and into tissues causing the swelling of extremitets or edema.
Darwin's idea of the survival of the fittest means that certain organisms are more likely to survive with they traits in particular environments. This is because some organisms are more fit to live in a given environment whether it be due to temperature, weather, or predators.
One example is that dark moths are more fit for survival than light moths in many areas because they are able to camouflage against dark tree bark.
Hope this helps.
Answer:
The correct answer would be - 120/88 or 112/80
Explanation:
Pulse pressure or PP is the difference between the top or higher number (systolic) and the bottom number (diastolic) blood pressure. Pulse pressure can find out by the systolic minus the diastolic of Blood pressure.
For example, if an individual's resting BP is 120/80 millimeters of mercury (mm Hg), the normal PP is 40 which is considered a healthy pulse pressure. So, as per the normal BP 120/80, if the pp was 32 than the bp would be 120/88 or 112/80.
