60/40 = l/100-l, = R/8

so R=12

now changed position 8 is proportional to l and 12 to (100-l)

8/12 = l/100-l

l = 40ohm

When frequency decreases, capacitive reactance XC​=1/2πνC​ increases and hence impedance in the circuit Z=√(R2+XC2​)​ increases and so current I=V/Z​ decreases. As a result, the brightness of the bulb is reduced.
 

When light moves from 1 medium to another, refraction takes place. And when light enters a denser medium, the ray bends away from normal and meets at a point above the actual point where they would have met, if the medium was absent. So, apparent depth decreases.

The heart is covered by pericardium. It is a fluid-filled sac It protects the heart. It is made up of an outer fibrous layer and inner serous membrane. Beneath pericardium, epicardium is present.

Benefits of Exercise:
Exercise has numerous benefits for our physical health. One of the correct benefits of exercise is that it increases the flow of blood to the muscles. Here are some detailed explanations:
1. Improved cardiovascular health: Regular exercise helps improve the health of our heart and blood vessels. It increases the flow of blood to the muscles, including the heart, which helps to strengthen the heart muscle and improve its efficiency.
2. Stronger muscles and bones: Exercise stimulates the growth of muscles and increases bone density. This can help prevent conditions like osteoporosis and reduce the risk of fractures.
3. Weight management: Exercise helps in maintaining a healthy weight by burning calories. When combined with a balanced diet, regular exercise can assist in weight loss or weight maintenance.
4. Mental well-being: Exercise is not just beneficial for physical health, but it also has a positive impact on mental well-being. It releases endorphins, which are natural mood elevators, and can help reduce symptoms of depression and anxiety.
5. Increased energy levels: Regular exercise improves blood flow and oxygen delivery to the muscles and tissues, leading to increased energy levels and reduced feelings of fatigue.
6. Improved sleep: Engaging in regular exercise can promote better sleep patterns. It can help you fall asleep faster, deepen your sleep, and wake up feeling more refreshed.
7. Reduced risk of chronic diseases: Regular exercise has been linked to a lower risk of developing chronic conditions such as heart disease, type 2 diabetes, and certain types of cancer.
In conclusion, exercise offers a wide range of benefits for good physical health. One of the correct benefits is that it increases the flow of blood to the muscles, which contributes to improved cardiovascular health and overall well-being.

In an open ocean, the large numbers of phytoplankton quickly complete their life cycles and sets of new population or crops of phytoplankton are formed every few hours or days. Thus, the cumulative energy contents that these generation after generation of phytoplankton trap in course of a year is certainly much more than trapped by only a few generations of herbivorous fishes in the corresponding time and space. The energy content trapped by the carnivores living on the herbivorous fishes is the leat.

Answer:
The removal of waste substances from the body is called excretion. Here is a detailed explanation:
Definition:
Excretion is the process by which waste products and toxins are eliminated from the body. It is an essential function of living organisms to maintain homeostasis and prevent the accumulation of harmful substances.
Process of excretion:
1. Urinary System: The kidneys filter waste products, excess water, and toxins from the blood to produce urine. Urine is then excreted through the urinary system, which includes the ureters, bladder, and urethra.
2. Respiratory System: The respiratory system eliminates carbon dioxide, a waste product of cellular respiration, through exhalation. Oxygen is taken in during inhalation, and carbon dioxide is expelled during exhalation.
3. Digestive System: The digestive system eliminates undigested food and other waste materials through defecation. The large intestine absorbs water from waste products, forming solid stools that are excreted through the rectum and anus.
4. Skin: The skin plays a role in excretion through perspiration or sweat. Sweating helps regulate body temperature and eliminates certain waste products such as urea and salts.
Importance of excretion:
- Excretion helps maintain the balance of substances within the body, preventing the buildup of toxins.
- It ensures the removal of metabolic waste products, such as urea and carbon dioxide, which can be harmful if accumulated.
- Excretion is essential for maintaining homeostasis and overall health.
In conclusion, excretion is the process of removing waste substances from the body. It involves various systems and organs working together to eliminate waste products and maintain a healthy internal environment.

Some animals undergo long winter sleep to avoid cold condition, called as hibernation. Organism survive without taking food and water.
