Biology

Answer:

Chromosomes are coiled structures made of DNA and proteins. They contain genes, which basically code for proteins. Chromosomes form after DNA replicates. In other words, chromosomes form as DNA becomes foiled during the process of prophase I, thus creating chromosomes.

Hope this helped! :)

Answer:

Explanation:

Objective(s): To see what will happen to the egg after soaking in water for 72 hours checking it every 24 hours

Hypothesis: I think the egg will get very thick because it will absorb the water

Variables:Independant: The circumference is measured every 24 hours

                Dependant: the circumference

                 Control: The same unit of measurement was used ( CM)

Materials:

Raw egg

String or thread or yarn

Ruler

White vinegar

Tap water

Syrup

Jar with lid (like a mayonnaise jar or something big enough to put the egg in)

Procedures:

Data and Observations:

Record your observations from the experiment in either the hands-on lab or the teacher-led video. Don't forget to include at least two detailed observations and the measurement of the egg's circumference in centimeters.

Time (hrs) Observations Circumference (cm)

0                the egg looks normal: 53 CM

24             Its starting to get bigger: 54 CM

48              It wont start getting bigger: 56 cm

72                Its huge: 57 CM

Conclusion:My hypothesis was correct. I knew the egg would get bigger because the water would absorb into the egg.  The egg grew 4 cm

Was your hypothesis correct? Why or why not?My hypothesis was correct. I knew the egg would get bigger because the water would absorb into the egg.

How much did the egg change in size? (answer should be in centimeters)The egg grew 4 CM

Refining the Experiment:

Continue this experiment by removing the egg from the water and covering it in syrup. Be sure to allow at least 24 hours before making your observations. Handle the egg very carefully!

Predict what will happen to the egg and syrup system.

When refining your procedures describe the following:

How will the change in the syrup and within the egg be measured or identified?

How will you determine when homeostasis has been reached in your egg and syrup system?

Be sure to address each bullet in the conclusion of your lab report:

Was your hypothesis correct? Why or why not?

How much did the egg change in size? (answer should be in centimeters)

SORRY I DIDN'T HAVE TO DO THIS PART ON MINE.
