Correct Answer: B. 20 to 30

The ozone layer is primarily located in the stratosphere, at an altitude of approximately 20 to 30 kilometers above the Earth’s surface.
The correct answer is:
B. 20 to 30.
The ozone layer spans a broader range of altitudes in the stratosphere, typically between 15 and 40 kilometers (10 to 25 miles). However, the concentration of ozone is most prominent in the 20 to 30 kilometers range, which is why it is often considered the core region of the ozone layer.
For the question provided, the best answer is still:
B. 20 to 30.
This reflects the altitude range where the ozone layer’s density is highest.

One of the most common symptoms associated with the onset of osteoporosis is a loss of height. This is often due to the compression fractures of the vertebrae, resulting in a reduction in the height of the spine.

Correct Answer: A. Severe Bleeding, Anemia, Infections, Exlampsia, Unsafe Abortions

The major causes of maternal deaths, as identified by global health organizations and researchers, are typically related to complications during pregnancy, childbirth, and the postpartum period. The options mentioned in A cover some of these key causes:
A. Severe Bleeding, Anemia, Infections, Eclampsia, Unsafe abortions:
Severe Bleeding (Hemorrhage): Excessive bleeding during childbirth or the postpartum period can lead to maternal mortality.
Anemia: A condition characterized by a lack of red blood cells or hemoglobin, anemia can contribute to maternal mortality, especially if severe.
Infections: Infections, whether occurring during pregnancy, childbirth, or the postpartum period, can lead to complications and maternal deaths.
Eclampsia: Eclampsia is a serious complication of pregnancy characterized by seizures. If not managed promptly, it can lead to maternal mortality.
Unsafe Abortions: Complications from unsafe abortions pose a significant risk to maternal health and can result in maternal deaths.

It is a transitional stage of physical and psychological development between childhood and adulthood.
During adolescence, individuals undergo significant changes, including puberty, cognitive development, and the formation of identity.

Correct Answer: D. Fluorine

Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.

Correct Answer: C. 300 grams
