5. Radioisotopes
Radioisotopes are isotopes that are radioactive—they spontaneously emit energy (or radiation) when their nucleus breaks down. The term for this process is radioactive decay. When the process involves a change in the number of protons in the nucleus, the atom can change into another element. In one type of radioactive decay, a neutron in the nucleus splits into a proton and an electron. This split decreases the number of neutrons by one and increases the number of protons by one, but since protons and neutrons have approximately the same mass, the mass number stays the same. Since the number of protons changes, the atom becomes a new element.
Carbon-14 has 8 neutrons and 6 protons. When this radioisotope undergoes the radioactive decay process discussed above, it becomes nitrogen-14.
The number of protons in nitrogen-14 is?

Answers

Answer 1

Answer:

7

Explanation:

The number of proton becomes 7 in nitrogen- 14 because there is one proton increase in the nucleus as a result of radioactive decay. There are 6 number of protons and 8 number of neutron in the nucleus of carbon-14 isotope. when the radioactive decay occurs, there is decrease occur in neutron number by removing one neutron and number of proton increases in the nucleus due to addition of one proton so that's we can say that the number of proton in nitrogen-14 is 7.

How is an agrarian society likely to address the problem of crops spoiling
before they can be brought to market?
A. By cutting down forests to produce more cropland
O B. By switching from coal-burning power plants to solar energy
production
O C. By developing irrigation techniques that conserve water
O D. By creating more efficient methods of food preservation

Answers

Answer:

The correct answer is D) By creating more efficient methods of food preservation

Explanation:

By creating more efficient methods of food preservation. Therefore, option (D) is correct.


What is an Angrarian Society?

In an agrarian society, where agriculture is the primary means of livelihood, the problem of crops spoiling before they can be brought to market can have significant economic and social implications. Cutting down forests to produce more cropland or switching from coal-burning power plants to solar energy production would not directly address the problem of crop spoilage.

Developing irrigation techniques that conserve water could help improve crop yields and reduce water wastage, but it would not necessarily address the problem of crop spoilage. On the other hand, creating more efficient methods of food preservation would help prevent crops from spoiling before they can be brought to market, thus reducing food waste and increasing food security. Some examples of food preservation methods that can be used in an agrarian society include canning, drying, and pickling.

In soil science, a soil type is a taxonomic unit. A distinctive soil type is made up of all soils that have a certain set of well-defined features in common.  

The phrase "soil type" refers to the study of soil classification, which is concerned with the orderly classification of soils. Every soil on the planet is a particular soil type.

The majority of soil types in hierarchical soil classification schemes are in the higher or intermediate level. Typically, a soil type can be further broken down into subtypes, and in many systems, multiple soil types can be joined to form higher category entities.

QUESTION 9
Which of the following is not a property of fibre?
O a. It delays gastric emptying
Ob.it
It provides a feeling of satiety
O c It elevates blood glucose levels
O d. It contributes 6-10 kilojoules per gram.

Answers

Answer: The correct option is C ( It elevates blood glucose levels).

Explanation:

All animals feed on ready - made food. This food is made up of several groups of substances.All food taken in by an animal can be divided into six groups of food substances or nutrients. They are carbohydrates, proteins, fats and oil, mineral salts, vitamins and water.

Fibres is defined as foods that are usually of plant origin which are indigestible and stimulates movement of the bowels by providing bulk to the intestinal content.

Examples of the plant based food which are rich in fibre include:

--> grains,

--> fruits,

--> vegetables,

--> nuts, and beans.

Fibre is further divided into two:

--> Insoluble fibre: This is also called roughages. They include fruits and vegetables with their backs, whole grains.

--> Soluble fibre: This is the jelly-like fibre that dissolves in water. It includes the flesh of fruits and vegetables, oats.

All fibers can slow the absorption of sugar and fat from food, and therefore help prevent spikes in blood sugar. Therefore the option that fibre elevates blood glucose levels is NOT a property of fibre.

Answer:

c It elevates blood glucose levels

Explanation:

Elevation of blood glucose levels is not the property of fiber because fiber helps control blood sugar. Fiber can't be converted into glucose or fiber does not have glucose so the concentration of glucose can not be increased if more fiber is eaten. Fiber provides a feeling of satiety as well responsible for gastric emptying. One gram of fiber produces 8 kilojoules per gram. So we can conclude that blood glucose level can't be increases due to fiber.

He lay on his armour-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked.(2) "What's happened to me?" he thought. It wasn't a dream. His room, a proper human room although a little too small, lay peacefully between its four familiar walls. A collection of textile samples lay spread out on the tableSamsa was a travelling salesmanand above it there hung a picture that he had recently cut out of an illustrated magazine and housed in a nice, gilded frame. It showed a lady fitted out with a fur hat and fur boa who sat upright, raising a heavy fur muff that covered the whole of her lower arm towards the viewer.(3) Gregor then turned to look out the window at the dull weather. Drops of rain could be heard hitting the pane, which made him feel quite sad. "How about if I sleep a little bit longer and forget all this nonsense," he thought, but that was something he was unable to do because he was used to sleeping on his right, and in his present state couldn't get into that position. However hard he threw himself onto his right, he always rolled back to where he was. He must have tried it a hundred times, shut his eyes so that he wouldn't have to look at the floundering legs, and only stopped when he began to feel a mild, dull pain there that he had never felt before.Which of the following is the best summary of paragraph 2?Gregor tries to go back to sleep, but the weather keeps him up.Gregor wants to forget his trouble, but his body will not allow him.Gregor knows by the reality surrounding him that he has become a bug.Gregor wakes to realize he was dreaming about being a bug.
