Part 1: Make a graph of each set of data. For the first set, plot the start location data on the x-axis and the box's average sl

ide distance on the y-axis. For the second set of data, plot the mass of the marble on the x-axis and the average distance the box slides on the y-axis. Four start locations were chosen for this experiment. Why was the potential energy of the marble different at each location? What happened to the potential energy as the ball rolled down the ramp? Why did the box slide backwards when the marble hit it? What kind of energy did the box have as it was sliding? Where did this energy come from? What is the relationship between the marble's starting position and the distance the box slid? Part 2: All the marbles started at the 40-cm mark in this experiment. Were their potential energies the same? Why or why not? Comparing the marbles, was there any difference in the average amount that the box slid after catching the marble? What is the relationship? Do all of the marbles have the same amount of kinetic energy at the end of the ramp? How can you tell? Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph. According to your data, was your hypothesis for each experiment correct? (Be sure to refer to your data and graphs when answering this question.) Summarize the conclusions that you can draw from this experiment. Use the questions above to guide your ideas. Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems. Give at least one more example from real life where the principles demonstrated in this lab are evident.

Dima020 [189]

Answer:

When seen on a Wright-stained peripheral blood film, a young red cell that has just extruded (lost its) nucleus is referred to as a polychromatophilic cell.

Explanation:

On Wright-stained smears, slightly immature red cells that do not have nuclei (reticulocyte stage) look blue-gray because they still have some ribonucleic acid in them (RNA). These cells are commonly referred to as polychromatophilic cells. Most of the time, polychromatophilic cells are bigger than mature red cells, and their blue-gray color makes them different from macrocytes.  Polychromatophilic red cells also tend to lack the central pallor.

When the remaining mRNA and ribosomes are stained with supravital dyes, they make the red cells look like a "reticular" mesh network. This is how the name "reticulocyte" came about. It is to be noted that not all reticulocytes show up as polychromatophils when stained with Wright-Giemsa.

What type of clouds are outside today
muminat

It would depend.

The weather might be different form mine. I can give you the four main types of clouds there are to help you identify them.

Cirrus clouds are wispy, feather like clouds. They are higher than the other types of clouds.

Stratus clouds are low level clouds that are light gray. They might cause fog.

Cumulus clouds are puffy, white clouds.

Cumulonimbus could are very tall clouds that produce T-Storms. They are a very dark gray.

There are other types of clouds, but these were the four I learned.
