pishuonlain [190]

The population of cactus dwelling birds will decrease and that of the animal they eat will increase.

Explanation:

When cacti is removed from the desert ecosystem, the birds that have their nest on the cacti will no longer have a home so they will migrate to other areas with favorable ecosystem.This will reduce the number of birds in this ecosystem.In turn, the animals that were feed by the birds will have the chance to multiply in numbers because a predator has been removed in the ecosystem.

Which situations would be most likely to engage the anterior cingulate cortex?
maria [59]

Answer:

Which of the following situations would be most likely to engage the anterior cingulate cortex?

A waiter walks over to your table at a restaurant and holds an open menu in front of you.

You walk into the elevator of your apartment building and press the button for your floor.

You enter your classroom and find someone sitting in your usual seat.

A good friend asks you to remind him of your telephone number.

Explanation:

In order to meet the demand of the surrounding environment   by adjusting  the  motor outputs from the brain to the environments ,a part of the emotion control part of the brain( limbic system) called the anterior cingulate cortex is responsible for this.

Anatomically, the limbic system is made up of the primarily the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus.

Based on the this its(anterior cingulate cortex) functions are formation of emotion in the limbic system, and  possessing  of memory and learning.

it is also a major  parts of  of pain networks for pain modulation and perception.

Therefore whenever there is  change in the environment  from the prestored condition in the brain,(e.g the usual seat  in the class room  occupied above) the anterior cingulate cortex adjust the motor input from the brain to adapt to the new environment to take an action,whih in this case  leads to the reclaiming of the seat or any other necessary proactive action.

Can you describe how a researcher might use naturalistic observation, case studies, and survey research to investigate gender di
Sati [7]

Answer:

The specification of the circumstance is characterized underneath in the interpretation category.

Explanation:

  • To continue investigating differences between men and women throughout the aggressive behavior of employees, a research scientist can use observation methods, research papers, or observational studies.
  • The naturalistic observation was being used without people's awareness to classify the actions of persons throughout the natural world. In this, the researcher examines individuals for some violent actions and often examines gender disparities throughout this workplace climate with aggressive behavior.
  • Throughout the case research, the researcher does a throughout-depth study on gender disparities mostly in current workplace violent behavior. Here also, not only would the researcher observe the behavior, and address questions about the gender gaps between the departments.
  • The investigator focuses on collecting information about the number, spread, and interrelationships of gender disparities throughout the large population through survey studies.

Hypothesis:

  • <u>Research hypothesis (H1): </u>There seems to be a correlation among both gender differences but instead aggressive performance in the workplace.
  • <u>Null hypothesis (H0):</u> There seems to be no correlation regarding disparities in gender as well as violent work performance.

Research approach:

Qualitative descriptive research design could be employed throughout the descriptive research. In all of this, more attention is put on gathering knowledge about prevalence as well as the interconnection of gender disparities with occupational violent behavior. In this, this same data will be gathered by face-to-face interviews, questionnaires on genetic factors, and occupational hostile behavior.
