Answer:
D
Explanation:
Observation is the first step to every scientific discoveries. From observation we form hypothesis [ intelligent guesses]; from that we subject our hypothesis to testing and the list goes on.
Cell contains hereditary information that is passed from cell to cell during cell division.
Living cells can be created from dead cells.
All cells perform similair metabolic activities.

Use the drop-down menus to identify the following statements as science or pseudoscience appeals to emotion and to science is has detailed research with reliable sources.
Pseudoscience is a proposition, a locating or a device of rationalization this is supplied as technological know-how however that lacks the rigor crucial to the medical method. Pseudoscience also can be the end result of studies this is primarily based totally on defective premises, a mistaken experimental layout or horrific data.
The pseudoscience is the appeals to emotion, while that of the science is repeats investigations.

Explanation:
Osmosis is the specific movement of solvent molecules through a semi-permeable membrane, while diffusion is the general movement of particles from high to low concentration in any medium.
Osmosis and diffusion are both fundamental processes of passive transport. Osmosis is a subset of diffusion that specifically involves the movement of solvent molecules, usually water, through a semi-permeable membrane to equalize solute concentrations on both sides of the membrane. It's essential in processes like maintaining cell turgidity.
On the other hand, diffusion encompasses the broader concept of particles, including solutes and gases, spreading out from areas of high concentration to low concentration. It occurs in various environments, not limited to membranes, and is vital for processes like gas exchange in respiration and the distribution of nutrients in cells.

Which best describes the difference between osmosis and diffusion?
Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration
Hope this helps, have a BLESSED and wonderful day! c:
The structure of an organism or its part, directly influences its function, which is central to biological adaptation. Adaptation involves developing physical characteristics, which aid survival in specific environments. While analogous structures represent adaptation to similar environments, homologous structures indicate shared ancestry.
Structure and function are fundamentally related to adaptation in biology. Essentially, the shape or structure of an organism, or any of its body parts, directly relates to that part's function or purpose. This idea, called the structure-function relationship, is central to the concept of adaptation—the process by which organisms evolve physical characteristics that help them survive in their environment.
For example, consider the fins of whales and the wings of bats. Even though these animals differ significantly in many aspects, they both developed structures (fins and wings) that perform similar functions (swimming and flying), which are best suited to their specific environment. These analogous structures represent an adaptation to a common environmental condition, despite the lack of a close evolutionary relationship, and is known as convergent evolution.
On the other hand, homologous structures represent a shared ancestry. For instance, the grasping hands of humans and chimpanzees, which serve the same function, indicate a common ancestor. Despite their structural similarities, the ways these structures are used could vary, showcasing how different environmental conditions can drive variations in function and contribute to evolutionary divergence.
A prime example of the structure-function relationship—the hallmark of adaptation—is observed in the various beak shapes of finches. Different shapes serve different purposes or functions, permitting birds to make the best use of available food resources in their respective habitats.
