In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.

In medical experiments, which group receives placebos?

the experimental group
the control group
both the experimental and control groups
neither the experimental nor control group

Answers

Answer 1

Answer:

 The control group

Explanation:

 The control group often exists in scientific experiments to determine the norm, or basically what would happen if the experiment were not performed at all.

   So the patients not receiving medicine would be a part of the control group.

Contemporary developmentalists maintain that human development is a continual and hierarchical process. The statement that most accurately depicts this viewpoint is:
A. early childhood experiences have little impact on adult behavior and attitudes
B. early childhood experiences are the major determinants of adult behavior and attitudes
C. early childhood experiences have a lasting impact on adult behavior and attitudes, but experience during other, later periods of life, also play a role
D. negative childhood events affect adult personality and behavior, but positive childhood events have little impact

Answers

Answer:

C). Early childhood experiences have a lasting impact on adult behavior and attitudes, but experiences during other, later, periods of life also play a role.

Explanation:

The third statement most adequately displays the perspective that the development of humans has been a recurring, as well as, stratified process. It shows that how the childhood incidents and experiences affect the development of an individual, his personality, behavior, and even his character traits and attitude he carries in life towards things. The importance of later life experiences also play a key role in evolution of a person which not only elaborates but also supports the idea that how humans develop in an arranged and recurrent manner. Hence, option C is the correct answer.

Answer:

Development refers to development-countryside developments that distinguish them from so-called developed countries in the economic performance, levels of living, sustainability, and equal conditions.

Explanation:

A developing country has a less developed industrial base and a low HDI in relation to other countries. This definition has nevertheless not been agreed universally. It is also unclear which countries fit in with this group. The term low- and middle-income (LMIC) often refers to countries' economies, but it is often used interchangeably.The World Bank separates the economies of the world into four groups based on the GNI per capita: high, medium, moderate and low revenues. The developing countries are all subgroups of the least developed, land-stricken developing countries and smaller island developing countries. Countries at the other end of the spectrum are generally known as countries with high incomes or developing countries.

Answers

Answer:

a. Peso, P = 352.8 Newton

b. Peso, P = 240.12 Newton

Explanation:

Dados los siguientes datos;

Masa del niño = 36 kilogramos

Aceleración debida a la gravedad sobre la masa = 6.67 m/s²

Sabemos que la aceleración debida a la gravedad es igual a 9.8 m/s².

El peso se puede definir como la fuerza que actúa sobre un cuerpo o un objeto como resultado de la gravedad.

Matemáticamente, el peso de un objeto viene dado por la fórmula;
