What is one way that early scientific practice differed from modern scientific practice? Early hypotheses were not based on observations. Early hypotheses were not tested by experimentation. Early hypotheses were formed from scientific questions. Early hypotheses were influenced by creative thinking.
Early hypotheses were not tested by experimentation.
One way early scientific practice differed from modern scientific practice is that early hypotheses were not tested by experimentation. In earlier times, many ideas were often developed based on philosophical reasoning, deductive logic, or theoretical speculation without the rigorous experimentation and empirical testing that are central to modern scientific methods.
Over time, the emphasis has shifted to the use of controlled experiments and systematic observation to test hypotheses and validate scientific theories.

During science class, students were instructed to develop a dichotomous key (a tool that allows the user to determine the identity of items in the natural world) in order to classify organisms into one of the six kingdoms of life. Ms. King, their teacher, provided them with this diagram. According to the diagram, the BEST way to separate all living things into two main groups would be to consider A) method of reproduction. B) consumer versus producer. C) cell type, prokaryotic versus eukaryotic. D) organization, unicellular versus multicellular.
which organelle of a prokaryotic cell contains genetic information? A.ribosomes B. nucleus C. nucleoid D. cell membrane
The right option is; C. nucleoid
Prokaryotic cells are simple cells that lacks a definite nucleus and some membrane bound organelles. Prokaryotic cells have a nucleoid region, which is an irregularly-shaped central region of the cell that contains the cell’s genetic information (DNA). Other organelles that can be found in prokaryotic cells include plasma membrane, cell wall, cytoplasm and ribosomes.
Nucleoid is an organelle of a prokaryotic cell that contains genetic information.
Further Explanation Living organisms are classified as either eukaryotes or prokaryotes. Eukaryotes Eukaryotes are living organisms that contain a nucleus and other membrane bound organelles. The function of the nucleus being storage of genetic materials and also controlling all cellular activities. Eukaryotes are either single celled or multicellular for organisms such as plants, animals, and fungi. Prokaryotes Prokaryotes are organisms that lack a nucleus and other membrane bound-organelles such as ribosomes, Golgi apparatus, endoplasmic reticulum, etc. Genetic information in prokaryotes is contained in a nucleoid which is a concentration of DNA that lacks an enclosing membrane. Nucleoid contains large circular DNA that has genes that are required for the survival and reproduction of the cell. Other Cellular organelles. Nucleus Nucleus is a type of cellular organelle found in eukaryotic cells whose function is to control all the cellular activities undertaken by the cell. Additionally, the nucleus house the DNA which carries the genetic material of an organism. Mitochondrion This is one of the cell organelle inside a cell. It is referred as the powerhouse of the cell, as it is where energy to drive all cellular activities is generated through the process known as cellular respiration. Ribosomes These are organelles where the synthesis of proteins takes place through a process known as translation. They are found in the cytoplasm, either freely suspended or attached to rough endoplasmic reticulum. Cell membrane It is a structure that encloses the cell contents in the cytoplasm from the external environment. It’s functions is to control materials entering in and out of the cell through selective permeability.

Which of the following functional groups contains only carbon, hydrogen, and oxygen? A) carboxyl group B)amino group C)sulfhydryl group
The functional group that only contains carbon, hydrogen, and oxygen is carboxyl group. The correct option is A.
What is a functional group?Functional groups are groups of atoms in a substance that control the complex's chemical behavior include groupings like the hydroxyl group in an alcohol.
The functional group refers to the area of a substance that interacts with another component.
An atom or group of atoms known as a functional group is in charge of a certain chemical characteristic of an organic molecule.
Functional groups are a way to categorise organic molecules. An organic compound with a functional group has a different attribute from what it would otherwise have.
The two functional groups hydroxyl (single-bonded OH) and carbonyl (double-bonded O), which are both connected to one carbon atom, are combined to form carboxyl groups.
The amino group have nitrogen along with carbon, hydrogen, and oxygen, while sulfhydryl group have sulfur in addition.
Thus, the correct option is A.

4. Which aquatic ecosystem typically forms along coastlines where fresh water and salt water meet, leading to varying degrees of salinity?
If a cell is placed in salt water water leaves the cell by
When a cell is placed in saltwater, water leaves the cell through osmosis because of the higher solute concentration in the saltwater solution.
Explanation:In a saltwater solution, a cell will lose water through a process called osmosis. Osmosis is the movement of water molecules from an area of lower solute concentration (inside the cell) to an area of higher solute concentration (in the saltwater solution). Since saltwater has a higher solute concentration than the cell, water will move out of the cell to achieve equilibrium.

which of the following parts of a nuclear power plant is turned on by steam
A.Control rods
B.Ractor vessel
C.Turbine
D.Generator
Answer:
Option (C)
Explanation:
A nuclear power plant is considered to be a thermal power station where the main source of heat is the nuclear reactor. Here, energy is released in the form of heat that helps in generating steam. This steam then initiates the motion of the turbines that are connected to a generator. These turbines when rotates produce electricity.
These nuclear plants are less costly and they do not emit any kind of pollution. They are very efficient to use but has certain disadvantage, that the waste materials it releases contain some amount of radioactive element in them and are difficult to dump.
Thus, the turbines in a nuclear power plant is turned on by the steam.
Hence, the correct answer is option (C).

fill in the name of the processes such as freezing that are represented
These are names of processes linked to the changes in physical states and properties of matter. They include an isentropic process with no change in entropy, irreversible processes which cannot return the system or surroundings to an initial state, isothermal processes that operate at constant temperatures, isobaric and isochoric processes that maintain constant pressure and volume respectively.
Explanation:The name of the processes such as freezing can be related to the ones annotated in the representation below.
Isentropic: This is a process that proceeds without any change in entropy. It's an ideal process that assumes perfect insulation, hence no exchange of heat with the surroundings.Irreversibility or Irreversible Process: These are processes that cannot return the system or the surroundings to its initial state. Heat transfer, free expansion, mixing of gases, and chemical reactions are examples.Isothermal Expansion or Isothermal Process: These are transformations that take place at a constant temperature. Gas expansion with heat addition is an example.Isobaric process: This is a thermodynamic process whereby the pressure remains constant.Isochoric process: A process during which the volume remains constant.Learn more about Thermodynamic processes here:https://brainly.com/question/31237212
