Why do you think the pace of the development of society is not equal everywhere?
Write in four points.

Answers

The correct answer to this open question is the following.

These are the four points that explain the reason why the pace of the development of society is not equal everywhere.

1.- Education. Formal education is of the utmost importance in societies that are considered developed or part of the first world. On the other hand, lack of education is a major reason why people stay ignorant and progress is minimum. Governments must invest in a good public education system with opportunities for all.

2.- Infrastructure. If the country cannot cover the necessities of its citizens, it would be more difficult to develop the kind of infrastructure that allows growth for the nation. This means poor means of communication, poor road conditions, lack of trade systems, poor health services, and limited resources to create jobs in industries.

3.- Culture. People's idiosyncrasy has a lot to do with the way they think and behave. This directly impacts the way people see life, personal progress, ambitions, and aspirations.

4.- Location. Often, geographical location limits the progress and development of a country. For instance, Middle East countries have a problem accessing water resources. Or countries that have geographical features such as mountain ranges or deserts that limit communication and trade with other countries.

The pace of development of society is not the same everywhere, because geography, economy, natural resources and technological development are not the same, these being important points for the development of a society.

What is Social Development?

Social development is an important factor found in society, capable of changing its social and economic course, so that the increase in social development means an increase in human capital and in social capital itself, moreover, it means more than a quantitative issue. , but also something qualitative.

With this information, we can conclude that pace of development of society is not the same everywhere, because geography, economy, natural resources and technological development are not the same, these being important points for the development of a society.

Answers

Answer:

Lipids, proteins, nucleic acids, and carbohydrates.

Explanation:

These carbon-based molecules make up all organisms and living things. These 4 molecules are the four major types of carbon based molecules

Lipids, proteins, nucleic acids, and carbohydrates are the four main types of carbon based biomolecules.

What are biomolecules ?

Biomolecules can be defined as the basic component of all living cell and it is the primary building blocks like Carbohydrates, Proteins, Fats, Nucleic Acids.

Carbohydrates or sugars are the primary energy source of body which are composed of polyhydroxy aldehydes or ketones formed by hydrolysis reaction; It can be monosaccharide, oligosaccharide and  polysaccharides.

Proteins are the structural unit and it express character of a gene and synthesized by translation from RNA; It is a polymers of amino acids, can be up primary, secondary, tertiary and quaternary protein.

Nucleic acids are the house of all genetic material of the cell which  are up two types namely, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Lipids are insoluble substance as it can not dissolve in water, soluble in only in non-polar solvents, include sterols, fat-soluble vitamins, mono-, di- or triglycerides, phospholipids, etc.

2. Energy is the fuel of life.
1. Diamond and coal are basically different forms of carbon.​

Answers

1. Energy is often considered the “Fuel of Life”. Primarily, it is needed for maintaining basic

metabolism (maintenance energy). Any excess is then used for production of meat (growth)

and/or eggs (production). Fed too much energy, hens become overweight (excess growth)

leading to poor production. If fed too little energy, hens begin using protein to meet their basic

maintenance needs and egg production may be compromised. As is the case with most things

in life, balance is the key. This article is an attempt to provide a flock manager with some tools

to use when making decisions on feeding energy to a breeder flock. Some of the research

cited is not current and is in no way intended to be anything more than an example of the

thought processes that may be helpful when making difficult decisions about feeding.

Energy is essential to meet our most basic needs: cooking, boiling water, lighting and heating. It is also a prerequisite for good health – a reality that has been largely ignored by the world community.

2. Coal and diamond are two examples of carbon allotropes, where the carbon atoms are bonded together in different configurations. These structural differences result in very different material properties, such as hardness.

On its own, carbon cannot form diamonds under the surface of the Earth. Both coal and diamond are made primarily from carbon, but their chemical structures are significantly different. Coal is formed from highly impure carbon that often contains elements like oxygen, selenium, hydrogen, nitrogen and sulfur.

Answers

Answer:

With the use of pesticides, farming can be faster and it also detracts insects and weeds

Answer:

One advantage inorganic fertilizers offer is that they are fast acting. These nutrient-rich salts dissolve quickly and are immediately available to the plants depending on them to provide essential nourishment in the form of nitrogen, phosphorus and potassium.Organic fertilizers usually contain plant nutrients in low concentrations. Since many chemical/inorganic fertilizers are concentrated and very soluble, it's easier to apply too much and damage your plants. Fresh, non-composted manure can damage your plants as well, because some manure contains harmful amounts of salts

HIF1α is a key player in angiogenesis. VHL is a protein required for the degradation of HIF1α in the normal oxygen level. Loss-of-function mutations in the VHL gene have been found to promote tumor growth. Please explain why these mutations can promote tumor growth?

Answers

Answer:

Explanation:

The VHL gene is a tumour suppressor gene that regulates cell growth and cell death. This gene is also located on chromosome 3. It functions to prevent rapid proliferation of cells. For a person to develop tumor both copies of the gene must be mistake or altered allowing for a loss of function that prevents its from causing degradation of HIF1α in the normal oxygen level as its it normal function. This then allows for the survival of HIF1α that promotes amgiogenesis promoting tumor development.

Answers

I couldn't see ur picture But I think from the options I think the answer is option D

D) organisms are made up of large number of cells

The feature of cell theory that is best demonstrated in the image is organisms are made up of a large number of cells. Thus, the correct option for this question is D.

What is Cell theory?

The cell theory was proposed by two famous scientists. i.e. M.J. Schleiden and T. Schwann. There are three assumptions that fall under the cell theory.

All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.It is the basic structural and functional unit of life.

Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells.

According to the three assumptions given above, the one which is best demonstrated by the image is that Organisms are made up of a large number of cells.

Therefore, the correct option for this question is D.

What is produced during the photosynthesis process?

A. Chloroplasts
B. Carbon Dioxide
C. Sugar

Answers

Answer:

Sugar

Explanation:

Photosynthesis is a process that certain organisms undergo. Plants, algae, and certain bacteria use this process to produce their own food. These organisms are called producers or autotrophs.

The equation for photosynthesis is:

carbon dioxide + water + light energy —-> glucose + oxygen

The plants turn carbon dioxide, water, and light energy from the sun into glucose and oxygen. The glucose, or sugar, becomes the food for the plant. The oxygen is the waste product.

The question asks us what is produced during photosynthesis.

Chloroplasts are not produced, but they are where photosynthesis takes place. Carbon dioxide is not produced, but it is used in the process. The correct answer is sugar. Sugar is produced, and it is the food for the organism.

Answers

Answer:

All systems work together to stabilize the body.

Explanation:

Certain systems work with each other in order to maintain homeostasis, which is essential for the body. For example, when blood circulates through the digestive system, it picks up nutrients absorbed by the body during its last meal. Additionally, blood carries oxygen taken in by the lungs. The circulatory system works with the respiratory system here to distribute oxygen to other parts of the body.

The universe can be explored using visible and invisible forms of light. These dishes (that detect radio waves from outer space) are part of a much bigger telescope in New Mexico. What is its name? A. Viking B. Voyager C. Very Large Array D. International Space Station

Answers

Answer: C. Very Large Array

There are 28 radio antenna, which are essentially satellite dishes. Only 27 are in operation at any given time, leaving one to sit out for maintenance. Astronomers using this array were able to observe black holes, and also observe the formation of interplanetary disks, among many other applications as well.

The reason why so many dishes are used is to increase the faint signal that is received from such a long distance away (often lightyears away). The 27 dishes are effectively the same as having a single radio dish that is 36 km (22 miles) in diameter. Having such a impossibly massive satellite dish is not feasible, so it's more practical to go with 27 smaller dishes.

why is waters high specific heat good for living things

Answers

Answer and Explanation:

Water's high specific heat means that the temperature of the water takes a long time to change. Living things that live near bodies of water experience temperatures different than inland, which is typically advantageous. During the summer, water remains cooler than the air for a period of time, and in the winter, the water remains warmer than the air for a period of time. In turn, the air in the areas with a body of water is typically increased or decreased a few degrees in temperature depending on the season. In the winter, this also produces what is called the "lake effect", in which snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water.
