What are all the ways scientists do investigations
Answers
The ways scientists do investigations is observational studies, surveys and questionnaires and case studies,
Scientists use various methods to conduct investigations and explore the natural world. These methods include:
1. Observational Studies: Scientists carefully observe and record natural phenomena or events without intervening or manipulating the environment. Observational studies are often used in fields such as astronomy, ecology, and anthropology.
2. Experimental Studies: Scientists design controlled experiments to test specific hypotheses or investigate cause-and-effect relationships. In experiments, variables are manipulated and controlled to observe their impact on the outcome. This method is common in chemistry, physics, and biology.
3. Surveys and Questionnaires: Researchers use surveys and questionnaires to gather data from a large number of individuals to assess opinions, attitudes, behaviors, or preferences. This method is prevalent in social sciences and market research.
4. Case Studies: In-depth investigations of a particular individual, group, or situation are conducted to gain detailed insights. Case studies are commonly used in psychology, medicine, and sociology.
5. Field Studies: Scientists conduct research directly in the natural environment, collecting data in real-world settings. Field studies are common in geology, environmental science, and wildlife biology.

Answer:
A solid will melt at the temperature at which the kinetic energy breaks theinter-molecular attractions.
Explanation:
The melting point is the state at which "a substance changes its temperature from a solid to liquid". At the melting point temperature, there is an equilibrium between the both the solid and the liquid phase. When the solid particle is heated by increasing the temperature the particle in the solid vibrate quickly and it absorbs kinetic energy.
It leads to the breaking of the organisation of particle in between the solid and that leads to the melting of solid. Thus, at the melting point, the kinetic energy breaks the inter-molecular attractions.
Answer: B) the temperature at which the kinetic energy breaks the intermolecular attraction

The bacteria in nasty environment undergoes multiple fission.
Explanation:
The bacteria is a unicellular prokaryotic organisms that are found in each and every places of the world. They can survive in extremes of temperatures and pH. They can save themselves through special processes in the extreme climates.
The bacteria undergoes multiple fission in these climates. They cover themselves up with a strong and tough capsule inside which they undergo several Binary fissions. This leads to the formation of multiple cells enclosed with a capsule.
With the return of the favourable climate, the capsule rupture and these newly formed cells come out.

with “Inside the nucleus,” because the particle is a neutron
with “Outside of the nucleus,” because the particle is a proton
with “Outside of the nucleus,” because the particle is an electron
Answers
Answer:
with “Outside of the nucleus,” because the particle is an electron
Explanation:
The table is best completed with “Outside of the nucleus,” because the particle is an electron.
The particle being described is an electron.
Electrons are negatively charged particles with a mass that is about of protons and neutrons
Mass(a.m.u) location charge
outside of the nucleus negative charge
Electrons orbits round the nucleus in distinct energy levels.
Final answer:
The subatomic particle described in the table is an electron, which is found outside of the nucleus of an atom.
Explanation:
The particle described in the table has a mass of 1/2,000 atomic mass units (a.m.u) and carries a charge. Based on this information, we can conclude that the particle being described is an electron. Electrons are negatively charged subatomic particles that orbit the nucleus of an atom, meaning they are found outside of the nucleus. Therefore, the correct entry for the location column in the table should be Outside of the nucleus.
