- Given below are two statements:
Statement I: Fig fruit is a non-vegetarian fruit as it has enclosed fig wasps in it.
Statement II: Fig wasp and fig tree exhibit a mutual relationship as the fig wasp completes its life cycle in the fig fruit and the fig fruit gets pollinated by the fig wasp. - An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Chemical Coordination and Integration - Hormones
Hormones are chemical messengers that are released directly into the bloodstream, where they are carried to organs and tissues throughout the body to perform their tasks. Hormones are released by the body's endocrine glands.
Functions of Hormones
Following are some important functions of hormones:
- Food metabolism.
- Growth and development.
- Controlling thirst and hunger.
- Maintaining body temperature.
- Regulating mood and cognitive functions.
- Initiating and maintaining sexual development and reproduction.
Types of Hormones
To regulate various functions, different types of hormones are produced in the body. They are classified as follows:
- Peptide Hormones: Peptide hormones are composed of amino acids and are soluble in water.
- Steroid Hormones: Unlike peptide hormones, steroid hormones are fat-soluble and are able to pass through a cell membrane.

- Estrogen
- Melatonin
- Progesterone
- Testosterone
