How does igneous rock become sedimentary rock?
Zinaida [17]

Explanation:

Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly. When it pours out on Earth's surface, magma is called lava. In this way, igneous rock can become sedimentary rock.

Any rock (igneous, sedimentary, or metamorphic) can become a metamorphic rock. If rocks are buried deep in the Earth at high temperatures and pressures, they form new minerals and textures all without melting. If melting occurs, magma is formed, starting the rock cycle all over again.

Which of the following attitudes is NOT important in science?
KengaRu [80]

The attitude that is NOT important in science is <u>b. having a closed mind.</u>

<h3>What is a closed mind?</h3>

A closed mind refers to a person who is not willing to consider different ideas or opinions.

A closed mind cannot engage in scientific inquiries.

Scientific inquiry helps scientists to study the natural world in diverse ways before proposing explanations based on the evidence derived from their scientific activities.

Thus, important attitudes in science include:

  • Curiosity
  • Creativity
  • Skepticism.
  • Honesty
  • Flexibility
  • Persistence
  • Open-mindedness
  • Tolerance of uncertainty
  • Acceptance of the provisional nature of scientific explanation.

But, having a closed mind cannot help in science.

You are studying an animal and inject fluorescein, a fluorescent dye, into a single cell on the surface epithelium of the animal
Viktor [21]

Answer:

The cells are connected by gap junctions.

Explanation:

A gathering of protein channels, which permits small molecules and ions to move between the neighboring cells is termed as a gap junction. The protein channels that form gap junctions comprise two connexons, of which one is situated in the membrane of one cell that combines and aligns with the connexon of the adjacent cell.  

This association produces a spontaneous pathway, which permits the small molecules and ions to pass passively from one cell to another. The gap junctions are found in all the kinds of cells, however, they are not found in skeletal muscle, RBCs, and blood lymphocytes.  

Thus, the passing of the fluorescent dye from one cell to another shows that the two cells are connected with the help of gap junctions.
