Describe the process of development and birth in humans.

✓

Answer

(i) The zygote formed after fertilization in the oviduct, undergoes repeated mitotic divisions and embryo is formed.
(ii) Meanwhile, it is pushed towards the uterus.
(iii) Once it reaches the uterus, it is implanted and further development occurs after implantation.
(iv) An organ called as placenta is formed for supply of food material during the growth of the embryo in the uterus.
(v) Embryonic development is completed approximately within nine months after fertilization following which birth takes place.

An organic compound A having the molecular formula $C_3H_8O$ is a liquid at room temperature. The organic liquid $A$ reacts with sodium metal to evolve a gas which burns causing a little explosion. When the organic liquid A heated with concentrated sulphuric acid at $170^\circ C,$ it forms a compound $B$ which decolourizes bromine water. The compound $B$ adds on one molecule of hydrogen in the presence of Ni as catalyst to forms compound $C$ which gives substitution reactions with chlorine.

What is compound $A?$
What is compound $B?$
What type of reaction occurs when $A$ is converted into $B?$
What is compound $C?$
What type of reaction takes place when $B$ is converted into $C?$

Read the passage and answer the questions based on it.
If heat is exchanged between a hot and cold object, the temperature of the cold object goes on increasing due to gain of energy and the temperature of the hot object goes on decreasing due to loss of energy. The change in temperature continues till the temperatures of both objects attain the same value. In this process, the cold object gains heat energy and the hot object loses heat energy. If the system of both the objects is isolated from the environment by keeping it inside a heat-resistant box then no energy can flow from inside the box or come into the box. In this situation, we get the following principle.
Heat energy lost by the hot object = Heat energy gained by the cold object. This is called the ‘Principle of heat exchange’.
