Answer:

The major function of neuron is the transmission of nerve impulse.

Explanation:

Neurons or nerve cells are the electrically excitable cells that transmit information from one part of the body to another by transmitting nerve impulse. Neuron is the structural and functional unit of nervous system.

Sensory neurons carry nerve impulse from the receptor cell and transmit it to the brain. Inter neurons are present between sensory and motor neuron. Motor neurons carry information from the brain to the effector organ. Effector organ may be any muscles, glands or hormones.

Answer:

Pass information by generating electric signals

Explanation:

Neurons are the fundamental unit of the nervous system. Neurons send information across the body through generation of electric signals called as action potential. There are basically three types of neurons

a) Sensory neurons which carry information from the sense organs in the form of impulse to the central nervous system (CNS)

b) Motor neurons – These carry information from the CNS to the body parts such as sense organs, muscles etc.

c) Interneurons – They are connecting neurons which are responsible for transferring information from one neuron to the other neuron.

Select THREE examples of pure substances.

Svetlanka [38]

Answer:

it would be C, D, E

A is a mixture

B is a mixture

C is a pure substance because Oxygen gas by the chemical symbol O2, is strictly pure

D is pure substance because Gold is one of the basic elements found naturally in nature, and as such, in its pure form

E is a pure substance because Both ice and liquid water are the same substance. H2O Though ice water is a mixture of both solid and liquid it is a pure substance, based on the molecular structure of its components .

F is a mixture

Why does many children have the same phenotypic characteristics as their parents?

Mama L [17]

So children look like combinations of their parents because they are. Each parentgives half of their genetic material to their children. The combination makes a unique combination of their parents genes. The scientific study of how traits are passed from parents to children is called genetics.

Q - Describe the Mitoses with the help of diagram. write its different phares and explain them.

bonufazy [111]

Answer:

Mitosis is a type of cell division in which single haploid cell (n) or diploid cell (2n) divides into two haploid or diploid daughter cells that are same as the parent.

Mitosis occurs in somatic cells of plants and animals. In this cell division, the two daughter cells have the same number of chromosomes as that in the parent cells.

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.

1.Prophase:-

It is the first visible stage in karyokinesis. The chromosomes appear as long coiled threads called chromatids. The chromatin becomes shorter, thicker and visible due to the condensation of DNA. The chromatins are now called chromosomes. Stainability of nucleus increase. Each chromosome starts to splits longitudinally into two sister chromatids. These sister chromatids are attached to each other at the centromere. The nuclear membrane and nucleolus start to disappear and by the end, it will be completely disappeared.

ii. Metaphase:-

Nuclear membrane and nucleolus completely disappears and simultaneously appearance of spindle fibers. Spindle fibers are attached to the centromere of a chromosome. The chromosomes are arranged on the equatorial plane. The process of gathering of chromosomes in equator is called congressional and plate formed is called metaphasic plate.

iii. Anaphase:-

The centromere of each chromosome splits into two sister chromatids and forms two daughter chromosomes. The daughter chromosomes are pulled towards the poles due to the contraction of spindle fibres and stretching of interzonal fibers. During polar movement, the chromosomes show different shapes i.e. J, U, V, L or I shaped in appearance. At the end of anaphase, each pole will get one set of daughter chromosomes. It is the shortest phase and is also known as a migratory phase.

iv. Telophase:- The daughter chromosomes reach respective poles and uncoil and become thin, long and visible. The spindle fibres start disappearing and finally disappear. The nuclear membrane and the nucleolus reappear.

Two nuclei are formed at the end of telophase. Both the nuclei have the same number of chromosome as the parent cell. It is the last visible stage of karyokinetic and is also known as reorganization phase.

It is followed by cytokines or division of cytoplasm.
