Meaning of PURKA : The loss of summer fur by an animal before the winter

A option

The nucleus is a membrane-enclosed organelle, found in most eukaryotic cells, which stores the genetic material (DNA). The nucleus is surrounded by a double lipid bilayer, the nuclear envelope, which is embedded with nuclear pores. The nucleolus is inside the nucleus, and is where ribosomes are made.

Golgi apparatus, Mitochondria, Ribosomes, Nucleus are parts of Eukaryotic Cells.
Functions

• They produce energy (ATP) and therefore are called the 'powerhouse of the cell'.
• Helps in regulating cell metabolism.
• Mitochondria possess their own DNA, RNA and components required for protein synthesis

A n s w e r :

The functions of the mitochondria, chloroplasts and peroxisomes are not coordinated with the endoplasmic reticulum, Golgi complex, lysosomes and vacuoles. Hence, they are not part of the endomembrane system.

Every animal-like cell has two small organelles called centrioles. They are there to help the cell when it comes time to divide. They are put to work in both the process of mitosis and the process of meiosis. Hope it hlps u !!!! ??

Cells are of different shape, size and structure according to the function they need to perform. So, if all the cells become of same size, shape and structure, it will be very difficult for multicellular organisms including humans to adapt better to the environment and survive. Also, the division of labour among the cells will be lost thus leading to difficulties in survival.

Nerve cells are usually branched and very long as they need more surface area to transmit the signals. Due to their long size they can easily carry messages in each and every portion around the body.

In mammals, after maturation, the nucleus disappears from the RBC to provide adequate space for hemoglobin to carry oxygen. Nucleus is responsible for cell division so the blood cells don't divide, they are produced by other cells within bone marrow. This is an adaptation which allows the red blood cell to carry more oxygen.

Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Plant Cells

• In addition to containing most of the organelles found in animal cells, plant cells also have a cell wall, a large central vacuole, and plastids. ...
• Plant cells with visible chloroplasts.
• The internal structure of a chloroplast, with a granal stack of thylakoids circled.

Mesosome is a convoluted membranous structure formed in a prokaryotic cell by the invagination of the plasma membrane. Its functions are as follows:

(1) These extensions help in the synthesis of the cell wall and replication of DNA. They also help in the equal distribution of chromosomes into the daughter cells.

(2) It also increases the surface area of the plasma membrane to carry out various enzymatic activities.

(3) It helps in secretion processes as well as in bacterial respiration.

 

The characteristics of prokaryotic cells are:

• Membrane bound cell organelles such as Mitochondria, Golgi apparatus, Chloroplasts are absent.
• A membrane bound well defined nucleus is absent.
• Genetic material is circular DNA and occurs naked in the cell cytoplasm. It is attached to the cell membrane and called nucleoid.
• The cell size ranges from 0.1 to 5.0 micrometre in size.
• The cell wall is a rigid structure which is made up of polysaccharides.

The characteristics of prokaryotic cells are: Membrane bound cell organelles such as Mitochondria, Golgi apparatus, Chloroplasts are absent. A membrane bound well defined nucleus is absent. Genetic material is circular DNA and occurs naked in the cell cytoplasm. ... The cell size ranges from 0.1 to 5.0 micrometre in size.

Answer: If the plasma membrane ruptures or breakdown then the cell will not be able to exchange material from its surrounding by diffusion or osmosis. Thereafter the protoplasmic material will be disappeared and the cell will die.

If there was no Golgi apparatus, various substances would not be in a position to be transformed in proper forms for further use. Certain substances, like protein and lipid, are important for the formation of plasma membrane. Hence the absence of Golgi apparatus will hamper the formation of new cells during cell division.

The Law of Demand states that other things remaining constant, the quantity demanded of a commodity expands with fall in its price and contracts with a rise in its price.
So, there is an inverse relationship between price and quantity demanded of a commodity. This is explained with the help of an imaginary table and the curve which is based on imaginary data:

Exceptions to the Law The law will not hold good under following circumstances:
(i) Conspicuous consumption The Law of Demand will not apply in case of costly items such as diamonds. These commodities will be demanded, even if the prices have gone very high.
(ii) Conspicuous necessities Certain things become the necessity of modern life, so we have to purchase these goods inspite of their price. The demand of television sets and automobiles has not gone down inspite of the increase in their price.
(iii) Ignorance If the consumer is not aware of the competitive price of the commodity, he may purchase more of the commodity even at higher price. Such ignorance of the buyers makes the Law of Demand ineffective.

A Constitution is necessary because of the following reasons:

• It is an important law of the land. It determines the relationship of the citizens with the governments.
• It lays down principles and guidelines which are required for people belonging to different ethnic and religious groups to live in harmony.
• It specifies on how the Government would be elected and who will have the power and the responsibility to take important decisions.
• It outlines the limits on the power of the Government and tells us about the rights of the citizens.
• It expresses the aspirations of the people about creating a good society.

The story, ‘We’re Not afraid to Die-if We Can All Be Together’ is a story of extreme courage and skill exhibited by Gordon Cook, his family, and crewmen in a war with water and waves for survival. In July 197 6, the narrator, his wife Mary, son Jonathan and daughter Suzanne set sail from Plymouth, England to duplicate the round-the-world voyage made 200 years earlier by Captain James Cook. They took the voyage in their professionally built ship, the Wavewalker, accompanied by two experienced sailors – Larry Vigil, an American and Herb Seigler, a Swiss, to tackle one of the world’s roughest seas – the Southern Indian Ocean. The first part of the journey, that is, about 105,000 kilometers up to Cape Town passed off very, pleasantly. On the second day out of Cape Town, -they began to encounter strong gales. Gales did not worry about the narrator. But the size of the waves was alarming – up to 15 meters, as high as the mainmast. On 25th December, the writer’s ship was in the southern Indian Ocean, 3500 kilometers to the east of Cape Town. The family celebrated their new year onboard the ship. At dawn on January 2, the waves were gigantic. Unfriendly weather and gigantic waves compelled the sailors to slow their speed, drop storm jib, and take other precautions. The danger was so obvious that the sailors completed a life-raft drill, attached lifelines, and life jackets. Suddenly at 6 pm, a tremendous explosion shook the Wavewalker and the author was thrown overboard. The ship was about to capsize when another gigantic wave hit it tossing it upright once again. The author was thrown back onto the deck, his head and ribs smashing against the walls. Despite his injuries, the narrator took charge of the situation. Somehow he found the wheel, lined up the stem for the next wave, and hung on till Mary appeared and took charge of the wheel. Larry and Herb started pumping out water like madmen. The whole starboard side bulged inwards. The narrator managed to cover the canvas across the gaps to prevent water from entering the ship. Then came more problems. Their hand pumps stopped working and electric pumps were short-circuited. Fortunately, the narrator found a spare electric pump under the chartroom that worked. The entire night was spent in pumping, steering, repairing, and sending radio signals. The narrator checked charts and calculated that He Amsterdam, a French scientific base was their only hope. Sue and Jon were injured but they said that they were not afraid to die if they could all be together. Sue’s head was swollen and she had a deep injury. The narrator became more determined to see his children’s courage. Finally, they reached lie Amsterdam, a volcanic island where they were welcomed by 28 inhabitants. Thus, the collective strength and never-failing optimism of the sailors made it possible for them to come out of the jaws of death. Though Jonathan and Suzanne did not do anything to save Wavewalker their courage, forbearance, faith, and optimism gave extra strength and persistence to the narrator and his team. The bravery of the strong-willed children is noteworthy in the story.

Yes magnitude of a physical quantity change with change in system of units.

 

If Length = 14 km. here magnitude is 14 and unit is km

As we know 1 km = 1000 m.If we change kilo meter to meter. then 14 km = 14000 m.
So here magnitude is 14000 and unit is meter. So if we change unit then magnitude also changes.

Super question
