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.

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.
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.
What hypothesis did Miller-Urey test in their experiment?
Answer: The Miller - Urey experiment is an experiment that was conducted by Stanley Miller and Harold Urey last 1950's. The hypothesis that they had tested and demonstrated was that several organic compounds could be formed by simulating the conditions of Earth's atmosphere.The Miller-Urey experiment provided the first evidence that organic molecules needed for life could be formed from inorganic components. Some scientists support the RNA world hypothesis, which suggests that the first life was self-replicating RNA.

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
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.
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.

The two elements, in looking at their atoms, have a total of 51 protons between them are Magnesium and Aluminum and Lithium and Scandium so option d. both A and B.
What are protons?
The protons are + charges particles found in the nucleus of the atoms.
NO. of protons in :
Magnesium and Aluminum- Magnesium has total of 12 proton and Aluminum has 13 total protons. Lithium and Scandium- Lithium has 3 and Scandium has 21So total no. of protons= 12+13+3+21= 50.
Thus it lies in between total of 51 protons in the periodic table.

Describe how individual cell breakdown energy rich molecules to provide energy for cell functions
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Explanation:
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy. This process is called 'cellular respiration'. The process is happens in all the cells in our body. Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

Answer:
espero que te sirva
Explanation:
El calentamiento global y el cambio climático tienen coincidencia en la principal
de sus causas, la emisión masiva de los diferentes gases de efecto invernadero o
GEI que retienen el calor dentro de la atmósfera y sobre la superficie terrestre a
través del denominado efecto invernadero.
El efecto invernadero es un proceso natural por el cual se produce la retención
del calor procedente del Sol en la atmósfera terrestre gracias a la capa de GEI que
se encuentra en ella. Estos gases en cantidades normales mantienen la
temperatura del planeta aproximadamente a 33ºC por encima de la que podría
tener si estos no existieran, por lo que el planeta sería demasiado frío para que se
desarrollase vida en él. Sin embargo, actualmente el efecto invernadero se está
volviendo tan intenso a causa de nuestras emisiones que comienza a tener graves
repercusiones en el medio.
El Grupo Intergubernamental de Expertos sobre el Cambio Climático (IPCC)
concluyó en el Quinto Informe de Evaluación (AR5) de 2013 que la influencia
humana había sido la causa dominante de este calentamiento producido desde la
mitad del siglo XX a través de la emisión de GEI, lo cual es una evidencia cada vez
mayor. Entre los principales gases emitidos se encuentran el vapor de agua, el
dióxido de carbono, el metano y el ozono.

All of the following affect groundwater contamination except Soil type.
What is Soil type?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.
