At the beginning of the Modern Age, sixteenth century, Spanish monarchs (Catholic Monarchs, Charles I, Philip II) wanted more and more territories, power, money ... For that, they did a series of things within the country (internal politics) and outside the country (foreign policy) to improve their wealth and gain more power. They began to conquer more and more territories. They succeeded and built the "Spanish Empire". However, by the seventeenth century, it would have gotten worse.

The foreign policy of the Catholic Monarchs (the alliances of Isabella of Castile and Ferdinand of Aragon) with the European Kingdom (Habsburg) for the movement policy with Portugal-England also, conquered the land in North Africa (Melilla, Algeria, and Libya).

1) If the economy is in recession, the CB will decrease its target for the interest rate by increasing the money supply. Another alternative is that the Gov decides to decrease taxes

2) According to the principal of monetary neutrality: In the long run the only effects of a decrease in the monetary supply is to reduce the agg price level...

3) Which of the following statements is false? According to the Solow's model, the contribution of the TFP to the GDP growth is computed as a residual, once we have subtracted the contribution physical & human capital.

4) If the nominal GDP is 1.6M, & real GD is 1.0M, the deflator is: 160

5) The nominal rate of unemployment around which the unemployment rate fluctuates is called the Natural rate of unemployment

6)

1)Which is the key concept of Socratic ethics?

His ethics around truth and good, the notion of good is a political category, not merely on individual one. This means that the good is what suits the polis or city, not this or that particular citizen. However, Socrates is aware of the need to limit this concept in a context in which the disparity of interests and expections leads to contradictory views about it. This is the meaning of the pedagogical work that will develop throughout his life and culminate with his sacrifice in favour of the laws of Athens. (His death sentence)

1. Which is the difference between selfish good and political good?
2. The knowledge of good precedes it’s application in the practical and political sphere: once the good is

Eutrophication

Eutrophication is the increase in nutrients, which increases the number of producers. This makes the water cloudy and prevents photosynthesis from taking place in the deeper levels, as there is a lack of sunlight. Heterotrophic organisms and decomposers intensify their activity, as there is more organic matter available. They also increase their oxygen consumption. In the end, the oxygen in the deeper level runs out, making it impossible for most species to survive.

Theory of Continental Drift

1912-1960: 225 million years ago, all the continents were joined together as one large supercontinent called Pangea. Over a very long period, the continents drifted apart to the positions they are today.

ACTIVITIES

Trasplant: is a surgical procedure in which diseased or injured organs, tissues, cells are replaced with healthy one from a donor.

|The donor can be another person, the same person or an animal|

Types of transplant:

-Autotrasplant: the recipient and donor are the same person

-Allogeneic transplant:  the donor is another person

-Xenotrasplant: the donor is an animal

Organ donation: is voluntary. Donors must be in good health, free from mental health problems, of legal age, not receive money in exchange for their organs, and give written consent

Types of donation:

-Cells:... Continue reading "A body is placed in a certain airstream" »

Demographic Regimes

Old Demographic Regime: Characterized by high birth and mortality rates (often catastrophic due to epidemics, famines, and wars), resulting in limited natural growth. This was typical of pre-industrial societies before the 19th century.

Demographic Transition Regime: Initially features high birth rates but lower mortality rates due to improved food availability, hygiene, and health, leading to increased natural growth. Towards the end of the transition, birth rates decline, and growth slows. This regime was present in Europe after the Industrial Revolution. The population pyramid was progressive, indicating a large base of young people and a small elderly population.

Modern Demographic Regime: Mortality and birth rates stabilize... Continue reading "Demographic Regimes and Population Density" »

Fertilization

Fertilization occurs when a sperm and an ovum unite, forming a zygote. This process requires both ovulation and sexual intercourse. It's only possible during a 24-48 hour window after ovulation, although sperm can survive up to 5 days inside the female reproductive tract. The sperm penetrates the ovum's covering, and a fertilizing membrane forms, preventing other sperm from entering. The nuclei of the sperm and ovum join. After fertilization, the zygote travels to the uterus. The corpus luteum continues to release progesterone, maintaining the thick endometrium walls and preventing menstruation. During its journey, the zygote divides, becoming a ball of cells called a morula (around day 4) and then a blastocyst (around day 5)....

Activites

1.) Difference between primary and secondary sex characteristics:

The primary are the sexual organs which are born with and the secondary are the physical characteristics developed during puberty

2.) Reproduction:

Is the creation of new individuals

3.) Explain the journey of sperm to the ovum:

After been secreted by the penis through the urethra, the sperm go from the vagina to the uterus, Then, they divide in 2 groups and go to each fallopian tube. If there’s an ovum, one of these single sperm will fertilize it, and they will form a zygote, divides and becomes a morula and later a blastocyst. On the 7 days, the blastocyst implants in the endometrium

4.)

Human reproduction is sexual. Two individuals from different sexes are needed. Each produces a type of gamete (reproductive cell).

Embryo development: Zygote undergoes cell division until it becomes an embryo that continues development up to being a fetus.

Childbirth: Baby is born, alive and fully formed

Development: The baby grows until maturity is reached (adulthood)

Changes leading to sexual maturity

• Primary sex characteristics: The reproductive organs
• Puberty: Stage from the ages 10-16, when majority occurs
• Adolescence: From puberty to adulthood, physical maturity and physiological and social changes, sexual desire appears
• Sex
