Answer:

The correct option is A. A theory changing because a new scientific method was developed.

Explanation:

A scientific theory can be described as wide explanations for a phenomenon to occur.  Scientific theories can be proven wrong whenever advancements are made and modern researches show that those theories were false. In contrast to this, a scientific law when made never changes. A scientific law is just a statement whereas a theory is a wide explanation of observations.

The experiments before Mendel were hence, theories which were subjected to change upon further research.

Evaluate the lab and data collected. What type of transport occurred in this lab? Explain your answer, including evidence from y
andreev551 [17]

To know what type of transport occurred the lab and collected data are needed. As they are not present an explanation of the different transport's types, will be given.

Water, proteins, ions, and molecules of different sizes can pass through the cell membrane using different types of transports. The transport that each molecule uses depends on the concentration, size, and polarity.

We can classify the types of transport as active and passive.

Passive transport is the one that does not need energy to happen since the molecules move from a place of high concentration to a one of lower concentration. In this group, we have:

  • Simple diffusion: small molecules in high concentration on one side of the membrane; move to the other side due to the difference in concentration.
  • Osmosis: water passes through the membrane from a place of low concentration of molecules to one of high concentration. Water moves inside or outside the cell to valance the concentration of solutes on both sides of the membrane.
  • Facilitated diffusion: uses proteins to transport large molecules, ions, or hydrophobic molecules from one side to the other. In this type of transport, we have proteins that form channels so those hydrophobic molecules can pass through the lipid membrane, and carrier proteins, which binds to a specific molecule changing their shape and transporting the molecule.

Active transport needs the<em> energy</em> to transport molecules; since it goes against the gradient's concentration. In this group, we have:

  • Sodium-Potassium pump: uses ATP to move sodium outside the cell and potassium to the inside. The ions with this transport go to where they are most concentrated.

In conclusion, there are different types of transport; they depend on the concentration or type of molecule. To find out what mechanism of transport occurred in the lab, look at the components of the experiment and analyze which of these transports could be present.

What is an example of reactivity?
igor_vitrenko [27]

Answer:

D. A bicycle rusting.

Explanation:

A. is incorrect because tearing a piece of paper is a physical change, not a chemical change.

B. is incorrect because we are just heating up the object. That only changes how fast the particles are moving and the change in state of matter.

C. is incorrect because we are adding heat to change a state of matter (from solid to liquid) and it is a physical change.

Therefore, only D. is the correct answer. Iron rusts, and when it does, it chemically changes into an iron oxide (rust).
