A therapist examining the roles, rules, expectations, power hierarchy, and boundaries within a
family is focused on which of the following areas of assessment?

Answers

Answer:

This question lacks options, options are:

A) family affect  

B) family strengths  

C) family process  

D) family organization.  

The correct answer is D.

Explanation:

The family is a system that is constituted by a network of relationships and made up of subsystems where each member evolves and develops through different stages, undergoing adaptation changes where the norms, rules, limits and hierarchies that work are essential in the family environment. Family therapy is understood to be that modality of therapy focused on the family as an object of intervention, its objective is to achieve the change of negative interaction patterns between the members of a family. Family organization refers to the interaction between all its members who are part of the same institution united by emotional ties. The organization describes the totality of the existing relationships between the people that make up the system, then the family organization refers to the functional demands, distribution of rules and transactional guidelines that constitute the ways of interacting of each individual within the family. The transactional guidelines are those that normalize the behavior of each member and are preserved by two systems of coercion; the first established by universal norms in turn existing roles and hierarchies; the second is the characteristic of each member involving its interests and expectations.

Which of the following lists correctly presents levels of organization from most complex to simplest?
O biosphere, community, organism, organ system
O cell, organelle, atom, molecule
O macromolecule, population, community, ecosystem

Answers

Answer:

O macromolecule, population, community, ecosystem

Explanation:

Macromolecules are very large molecules composed of atoms, such as complex carbohydrates, fats and proteins (for example, fats are macromolecules mainly composed of C, H, and O atoms). Macromolecules in turn associate to form cellular structures (eg. organelles, cytoskeleton, etc), which subsequently combine to form cells. Individuals are made up of one or more cells (i.e., unicellular and multicellular organisms, respectively). In the next level, populations are groups of individuals of the same species that live within a given area; whereas communities are groups of populations that live in a given area and interact with one another. Finally, an ecosystem can be defined as a group of populations (i.e., a community) and the abiotic factors (i.e., nonliving parts) of their environment that support them (e.g., water, light, radiation, temperature, etc).

The correct option is  macromolecule, population, community, ecosystem

The following information should be considered:

The correct order of the Earth's mechanical and compositional layers is as follows:

Compositional: crust, mantle, core. Mechanical: lithosphere, asthenosphere, mesosphere. Option B is correct.

The Earth's mechanical layers are defined by their physical properties, such as their rigidity and strength. The compositional layers are defined by their chemical composition.

The Earth's mechanical layers are:

Lithosphere: The outermost layer of the Earth. It is the rigid, solid outer layer that includes the crust and the uppermost part of the mantle.Asthenosphere: The layer below the lithosphere. It is a hot, soft layer of rock that can flow slowly.Mesosphere: The layer below the asthenosphere. It is a solid layer of rock that is denser than the asthenosphere.

The Earth's compositional layers are:

Crust: The outermost layer of the Earth. It is the thin, solid outer layer that includes the oceanic crust and the continental crust.Mantle: The layer below the crust. It is the thickest layer of the Earth and is made up of hot, solid rock.Core: The innermost layer of the Earth. It is made up of two parts: the outer core, which is liquid, and the inner core, which is solid.

What does it mean that a hypothesis must be ‘falsifiable’ in order to be valid?

\

Answers

Answer:

A hypothesis must be able to be proved wrong for it to be a useable hypothesis.

Explanation:

This is because if one can not disprove a hypothesis no experiment can be preformed to test the truthfulness of the statement. this does not mean that the question is not interesting or not worth asking. For example "There is a god" is an example of a hypothesis which is not falsifiable; whether or not this statement is true is still valuable information but it is not possible to answer using the tools of science.

Answer:

If an experimental observation can be made that disproves a hypothesis or model, it is said to be falsifiable. That is, one of the possible outcomes of the planned experiment must be a result that would contradict the hypothesis if achieved..

An athlete is training really hard and becomes dizzy and feels ill and weak. What could be the cause of this weakness, in relation to cellular respiration?

Answers

Answer:

Dehydration.

Explanation:

Dehydration is the cause of this weakness, in relation to cellular respiration because in cellular respiration water is produces when the glucose molecules are broken down for the release of energy. In this process, our body temperature increases so our body removes heat from the body with the use of water which leads to dehydration and the athlete feels hard and becomes dizzy and feels ill and weak.
