8 0

Answer:

C) They have similar antibiotic sensitivities to those of bacteria.

Explanation:

  • Ribosomes are the site for biological protein synthesis that is composed of macromolecular machine for protein synthesis.
  • In archaea they ribosomes comprise of three RNA molecules - 16S, 23S, and 5S.
  • The archaeal ribosome is a 70S ribosome that is composed of 50S and 30 S subunits.
  • The ribosomal binding site of archaeol ribosome may be similar to that of the bacteria, i.e. the Shine- Dalgarno sequence.
  • <em>However, the antibiotic sensitivity of the archaeal ribosome is different than those of bacteria as the r-protein sequence of the archaea are closer to that of eukaryote than the bacteria. </em>

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.

  • Most successions contains various stages that can be perceived by the assortment of species that overwhelm by then in the succession start when a zone is made in part or totally without vegetation due to an unsettling influence.
  • Some basic instruments of unsettling influence are fires, wind storms, volcanic emissions, logging, environmental change, extreme flooding, sickness, and irritation. Succession stops when species organization changes never again happen with time, and this community is said to be a peak network.
  • So, the correct answer is option a "primary succession"

The purpose of the digestive system is to break down food into simple molecules that the _______ of the body can use.
erma4kov [3.2K]


The purpose of the digestive system is to break down food into simple molecules that the cells of the body can use. 

Food is broken down  into its simplest units called monomers. Proteins are broken down into amino acids, fats are broken down into fatty acids and glycerol while carbohydrates are broken down into glucose units.

Glucose is taken in by the cells of the body and through the process of cellular respiration  is used to produce the ATP, the form of energy that cells use. Cellular respiration is the process by which cells use glucose to produce energy to power their functions.
