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.

The ________ is the site where lipids, triglycerides, and steroids are synthesized, as well as where calcium is stored within th
Ulleksa [173]

Answer:

smooth endoplasmic reticulum

Explanation:

Smooth endoplasmic reticulum differs from the rough endoplasmic reticulum in not having ribosomes on its surface. The smooth endoplasmic reticulum (SER) extends from the rough ER and forms a network of membrane tubules. The function of the smooth ER is to serve as a site for the synthesis of lipids, fatty acids, and steroids such as estrogens and testosterone.

Enzymes for the synthesis of these diverse biomolecules are present in smooth ER. The smooth ER present in the muscle cells is called the sarcoplasmic reticulum. It stores the calcium ions which are released into the sarcoplasm of muscle cells during muscle contraction.

In E. coli, the primary component of the mismatch repair system is the protein MutS. How does MutS recognize mismatched base pai
nignag [31]

Answer:

The best answer to the question, given the research found on this particular process in E. Coli specifically, would be: D) It identifies hemimethylated base pairs and methylates the unmodified base.

Explanation:

According to research on this pretty complicated topic, in E. Coli specifically, and other gram negative prokaryotes, it has been found that the presence, or absence of methylation will initiate MutS, which is a protein both in prokaryotes and eukaryotes responsible, in a full complex, of initiating and carrying out the full mechanism of DNA mismatch repair. As the daughter DNA strands are produced from parent strands, these first ones arise with several deletions and mismatches which need to be repaired and they are recognized due to the fact that daughter strands are hemimethylated. This circumstance activates MutS in E. Coli, who will then bind to the DNA strand that needs to be repaired and together with other members of the complex, like MutH and MutL, begin the process of repair.

In eukaryotes and other prokaryotes, the exact process by which DNA is repaired by MutS is still not totally known.

After DNA replication is completed, _____. After DNA replication is completed, _____. one DNA double helix consists of two old s
nlexa [21]

Answer:

each new DNA double helix consists of one old DNA strand and one new DNA strand

Explanation:

DNA replication is a semi-conservative process which means a new DNA duplex contains one old DNA strand and one new DNA strand because each DNA strand act as a template strand over which a complementary new DNA strand is made.

So after the completion of DNA replication, each new DNA double helix consists of an old strand of DNA and a new DNA strand. After the replication, only one strand is used for transcription. In RNA formation uracil comes in place of thymine.

In 3-5 sentences, describe how Copernicus developed his model of the solar system. In your answer, include an explanation for wh
labwork [276]

Answer:

Copernicus developed his model considering that the sun is a fixed point and planets rotate around the sun in the solar system. This is why he used the term "heliocentric" which means sun-centred. His model was not accepted by ancient philosophers because they said (1) if Earth is rotating, why we cannot feel the motion of Earth, and (2) if Earth is orbiting the sun, then the positions should be different when it is on opposite side of sun (parallax effect).
