Now, regarding reproductive health:
Four Points of Significance of Reproductive Health in Society:
1) Population Control: Reproductive health plays a crucial role in population control. Access to family planning methods and education about contraception contribute to controlling population growth, promoting a balance between resources and the number of people.
2) Maternal Health and Child Well-being: Reproductive health is essential for the well-being of mothers and children. Adequate maternal care, safe delivery practices, and proper postnatal care contribute to reducing maternal mortality rates and ensuring the healthy development of infants.
3) Prevention and Management of STDs: Reproductive health programs address the prevention and management of sexually transmitted diseases (STDs). Education about safe sex practices, awareness about STDs, and access to healthcare services help in preventing the spread of infections.
4) Gender Equality: Reproductive health is closely linked to gender equality. Ensuring that both men and women have equal access to reproductive health services empowers individuals to make informed decisions about their reproductive lives, fostering gender equity.
Two Areas Related to Reproductive Health That Have Improved Over the Past 50 Years in India:
1) Maternal Health and Child Mortality: Over the past five decades, significant progress has been made in improving maternal health in India. Initiatives such as the National Rural Health Mission (NRHM) and Janani Suraksha Yojana (JSY) have focused on providing maternal care, leading to a reduction in maternal mortality rates and improved child survival.
2) Family Planning and Contraception: Efforts to promote family planning and contraception have seen improvements. Various programs and campaigns have been launched to increase awareness about family planning methods, making contraceptives more accessible and encouraging responsible family planning practices.

If green plants were to disappear from Earth, it would have catastrophic consequences for the planet’s ecosystem and all life forms that depend on them. Green plants, particularly through the process of photosynthesis, play a crucial role in producing oxygen and converting carbon dioxide into organic compounds. This process is the foundation of the food chain, as it provides energy and nutrients for other organisms. Additionally, plants contribute to stabilizing the climate by absorbing carbon dioxide, a greenhouse gas that contributes to global warming.
Without green plants, oxygen levels would decline, leading to a shortage of breathable air for many organisms. The entire food web would collapse, affecting herbivores, carnivores, and omnivores alike. The extinction of plant-dependent species would have a cascading effect throughout ecosystems.
Regarding your second question, plants do not have a traditional excretory system like animals, but they do have mechanisms to eliminate waste products. One of the primary ways plants excrete waste is through the stomata, small pores on the surface of leaves and other plant organs. Stomata allow for the exchange of gases, including the release of oxygen produced during photosynthesis and the uptake of carbon dioxide for photosynthesis.
Plants also excrete waste substances through the roots, where they release various compounds into the soil. These compounds may include organic acids, ions, and other metabolic byproducts. The excretion of these substances helps regulate the plant’s internal environment and interactions with soil microorganisms.
In summary, while plants do not have a dedicated excretory system like animals, they have evolved mechanisms, such as stomata and root exudates, to manage waste products and maintain their physiological balance.
An object of height 1.2m is placed before a concave mirror of focal length 20 cm so that a real image is formed at a distance of 60 cm from it. Find the position of an object. What will be the height of the image formed?
Here, object height, h = 1.2 cm, Focal length, f = -20cm, Image distance, v = – 60 cm Object distance, u = ? Height of image, h′ =?

An element “X” has mass number 35 and the number of neutrons, is 18. Identify the group number and period of “X”.
Atomic number of X = Mass number of (X – No. of neutrons) = (35-18) =17 Electronic configuration = 2, 8, 7 Group number = 17, Period No. = 3
Atomic number of X = Mass number of (X – No. of neutrons) = (35-18) =17
