Nervous and hormonal system together perform the function of control and coordination in human beings. Justify the statement

The working together of various organs of human being in a systematic, controlled and efficient way to produce a proper response to various stimuli is known as coordination. In humans, the nervous and hormonal system together perform this control and coordination. Nervous system consists of receptors that receive the stimulus from surrounding environment and send the message received by them to the spinal Cord and brain in form of electrical impulses through the sensory nerves. The motor nerves then transmit the response to the effector. The effectors are mainly the muscles and glands of our body. Thus, endocrine glands secreting hormones are directly or indirectly controlled by the nervous system. Hence, control and coordination in humans (or animals) depends on two things for transmitting information, i.e. chemical signals of hormones and nerve impulses.
If they depended only on nerve impulses through nerve cells, only a limited range of tissues would be stimulated. Since, they get additional chemical signals as well, a large number of tissues are stimulated. This is why animals can show a wide range of response to stimulus.

Following are the points of Darwin’s theory of natural selection:

Over-production: Every organism has enormous potential to reproduce.
Struggle for existence: Population size of an organism is limited due to struggle between the members of same species as well as the members of different species. It is due to struggle for food, space and mate.
Variation: Due to struggle, the fit organisms possess some variations which are favourable, and they can leave the progeny to continue the favourable variations.
Survival of the fittest: The fittest organism survive to continue the favourable variations.
Formation of a new species: These variations when accumulated for a long time, leads to the origin of a new species.

Aman Singh 6 years, 1 month ago

Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the current is flowing. The magnetic field produced by an electric current is always oriented perpendicular to the direction of the current flow.

Kirandeep Kaur 6 years, 1 month ago

In simple words if carbon form c4 then it will be difficult for nucleus to lose 4 electrons or large amount of energy will required to lose 4 electrons so they cannot form c4

0Thank You

Kirandeep Kaur 6 years, 1 month ago

Bcoz carbon has four valence electrons in their outer most shell and they can be stable by gaining 4 more electrons to complete its octet Thats why they cannot form c4+ cations or c4- anions.

0Thank You

Aman Singh 6 years, 1 month ago

Carbon is unable to form C4− anion as its nucleus with six protons will not be able to hold ten electrons. Thus, carbon achieves noble gas electronic configuration by sharing its four electrons with other elements, i.e. it forms covalent compounds.

0Thank You

Abhiraj Arpan 6 years, 1 month ago

According to energy conservation carbon is not able to lose four electron or gain another four electron due to its small size.Therefore it shares electron forming covalent bonds
