Which graph shows the presence of nitrogen-fixing bacteria in the soil
Answer:
2
Explanation:
The graph that shows the presence of nitrogen fixing bacteria in the soil would be graph 2.
Nitrogen fixing bacteria are bacteria that are capable of converting atmospheric nitrogen into plant-usable nitrogen in the soil. The conversion is done in two stages;
1. First, atmospheric nitrogen is converted into ammonia.
2. Ammonium is converted into usable nitrate
Hence, the correct graph is the one in which the amount of atmospheric nitrogen decreases with a corresponding increase in the amount of ammonia. This would indicate the conversion of nitrogen into ammonia which is the first step in nitrogen fixation by nitrogen-fixing bacteria.
Graph 2 represents the presence of nitrogen-fixing bacteria in the soil.
This is because in this graph the concentration of atmospheric nitrogen (N2) is lower and the concentration of ammonium (NH4) is higher. The nitrogen-fixing bacteria converts or fixes atmospheric nitrogen that can't be absorbed by the plants into ammonium or nitrates which can be absorbed by the plants and make necessary amino acids for the body so we can conclude that graph 2 indicates the presence of nitrogen-fixing bacteria in the soil.

Explain how this experiment disproves the theory of spontaneous generation.
Answer:
The theory of spontaneous generation suggested that the living organisms can come from inanimate objects, however, it is an obsolete theory that is disproved by many experiments. The very first experiment that disapproved it was the experiment by Francesco Redi in 1668.
He demonstrated that maggots come from the eggs of flies instead of rotting meat. He placed raw meat inside of every jar. Half the jars he left open and the other half, he covered with mesh. In open jars, he found maggots after some time but covered jars have no maggots. That proved that the maggots come from eggs of flies rather than rotten meat.
The presence of flies on the meat is responsible for the production of maggots in meat.
This experiment disproves the theory of spontaneous generation because maggots are produced from the flies not the rotten meat. According to spontaneous generation, living organisms are formed or develop from nonliving matter.
So by performing this experiment we can see that maggots are formed when the flies feed on the rotten meat otherwise no maggots are present if the flies are not present there so that's why we can conclude that this experiment rejects the theory of spontaneous generation.

Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near mountains.
Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near rivers.
Answer:
D. Populations are greater in fertile areas that are close to freshwater sources, which is why more people live near rivers.
Explanation:
Population is greatly depend on the availability of water. Those areas are densely populated areas where water is present in sufficient quantity as compared to those areas have low population density where water is in low amount. The main reason is that water plays a vital role in our daily life which is used almost in every aspects of life. We can see that deserts have less population due to less water availability and areas attached to the rivers are densely populated due to more water availability.

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

How does the anaphase stage differ in the two phases of meiosis? A. Anaphase I separates sister chromatids and anaphase II separates homologous chromosomes into daughter cells. B. Anaphase I has homologous chromosomes attached to spindle fibres and anaphase II involves separation of these homologous chromosomes. C. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Answer:
The answer is Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces two haploid cells. Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. So, in meiosis, there are two anaphases - the anaphase I in meiosis I and the anaphase II in meiosis II.
In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicate, which are present as pairs of sister chromatids. In anaphase of meiosis II, since the cell is haploid, there are 23 chromosomes in duplicate, which are present as sister chromatids.

Explanation:
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?
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.
