Answer:
The history of basketball began with its invention in 1891 in Springfield, Massachusetts by Canadian physical education instructor James Naismith as a less injury-prone sport than football. Naismith was a 31-year old graduate student when he created the indoor sport to keep athletes indoors during the winters.

- <u>Physical Properties :</u>
- It is a crystalline colorless solid structure it is soluble in solution such as ether, alcohol, and chloroform but insoluble in water.
- It is dangerous when it is dry and is very volatile and decomposes when it reaches 103 c.
2. <u>Chemical Properties :</u>
- It causes swelling of the skin and undergoes free radical products that are highly reactive.
- It is irritant when it contacts the skin it breaks down to yield oxygen and benzoic acid.
<u>Explanation:</u>
- Benzoyl Peroxide is widely used in industry at large scale.
- It is formed when there is a reaction between hydrogen peroxide and benzoyl chloride.
- Benzoyl peroxide is used in bread and cheese as the bleaching agent and also used in cosmetics as hair coloring.
- Because of its antibacterial property and a peroxide group it is applied to the human skin to treat acne.
Answer: The correct option is (c). The total pressure doubles.
Solution:
Initially, only 4 moles of oxygen gas were present in the flask.
(
) ( according to Dalton's law of partial pressure)
....(1)
= Total pressure when only oxygen gas was present.
Final total pressure when 4 moles of helium gas were added:
partial pressure of oxygen in the mixture :
Since, the number of moles of oxygen remains the same, the partial pressure of oxygen will also remain the same in the mixture.
= Total pressure of the mixture.
from (1)
On rearranging, we get:
The new total pressure will be twice of initial total pressure.
Answer:Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar
Explanation: homoestasis is the process by which the body keep it's internal environment constant, regardless of change in the external environment. The human body has a normal range in which it's system operates and it uses homoestasis to keep these at constant.
Homeostasis could be positive or negative. It usually involves a sensor which detects the changes in the body and passes the information to the control center, a control center which receive information from the sensor and sends signals to the effectors and the effector which acts on the information sent by the control center to effect normalcy.
In this case, when a person eats food,he gets glucose. Blood sugar most be kept at constant so the endocrine system release the hormone insulin. Insulin helps to convert glucose to glycogen, which is the form it can be stored in the liver
When the blood sugar levels is low, the brain which is the control center causes glucagon to be released . This hormone converts glycogen to glucose
