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.

o-na [289]
<span>Genetic drift is the variation in different genotypes in a small population due to certain events that produce a large change in population, such as organisms dying out. The result of this genetic drift is that large changes in allele frequencies can occur in a short time.</span>

slamgirl [31]

Student 2 is right.

<h3>Constant variables</h3>

In research investigations, some variables should be kept constant across various experimental groups in order for the outcome of the investigation to be valid.

For example, in order to test how flatworms respond to different environments, one variable that should be kept constant is the flatworms. The flatworms to be used must be of the same species, sex, age, etc.

The investigator can then go ahead to divide the flatworms into two or more groups and then subject them to different environments. Other variables should also be kept constant in order to determine the effects that are only specific to the different environments only.

We see dehydration synthesis that has taken place in a protein with 200 amino acids. Which molecule will be removed doing the de
Kisachek [45]

Answer:

In the synthesis of a 200 amino acid protein, the molecule that is removed during the dehydration synthesis is water and, in this case, 199 water molecules have been removed.

Explanation:

Dehydration synthesis is a reaction through which polymers are formed by the union of monomers.

The formation of proteins is carried out by means of a dehydration synthesis reaction, where <u>amino acids are joined in a consecutive way</u>, uniting by peptide bonds. In this reaction, for each bond formed, one water molecule is lost.

The peptide bond occurs between the carboxyl of one amino acid and the amino terminal of another:

<em>COOH + NH₂ -----→ CO-NH + H₂O.</em>

When a protein of 200 amino acids is formed, a total of 199 H₂O molecules are lost in the reaction, as this is the total number of peptide bonds formed.

                                        Resources such as food, water, light, space, shelter                                     and access to mates are all limiting factors. If an organism, group or population does not have enough resources to sustain it, individuals will die through starvation, desiccation and stress, or they will fail to produce offspring.
