HELP!!! WILL GIVE MAX POINTS!! Doing a Lab Report on Natural Selection about beans. For example 20 dark red beans and 35 light red beans (kidney beans) Sample Response: When the volcano erupted, the dark red walking beans were easier to see. Thus, more dark red beans were eaten during days four, five, and six. If the pollution continued, there would be fewer and fewer dark red walking beans over time.
Questions being asked are:
1. What is the purpose of the lab?
2. What is your hypothesis for this experiment?
3. What methods are you using to test this hypothesis? (Outline the steps of the procedure in full sentences.)
4. 4. What graphs would clearly represent the trends in your data?
Your Student Guide includes information on which graphs to construct. Each graph should have the following items:
a. An appropriate title
b. Appropriate labels for each axis
c. An appropriate scale for each axis
d. The correct units for the data
Complete a rough sketch of each graph.
5. What do the data in your graphs tell you? (Explain in one or two sentences what trend is shown in each of your graphs.)
6. What does the data tell you about your hypothesis? (State how your hypothesis is either supported OR refuted by the data)
7. How does the data support your claim above? (Explain your statement above. Be sure to refer to specific pieces of data from your experiment that supports your argument)
8. 8. If you could repeat the experiment and make it better, what would you do differently and why?
There are always ways that experiments can be improved. Now that you are a veteran of this experiment and have experience with the procedure, offer some advice to the next scientist about what you suggest and why.
Answer:
During the days four through six the population of the dark red beans changed. The change was negative meaning that there was less dark red beans that light red beans. This happened because it was harder to see the light red beans because the color of the air changed. In result of that the zocco ate mostly dark red beans.

Which best describes chromosomal dilatation
Answer:Changes that affect the structure of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and disrupt the proteins made from those genes.
Structural changes can occur during the formation of egg or sperm cells, in early fetal development, or in any cell after birth. Pieces of DNA can be rearranged within one chromosome or transferred between two or more chromosomes. The effects of structural changes depend on their size and location, whether gene function is interrupted, and whether any genetic material is gained or lost. Some changes cause health problems, while others may have no effect on a person's health.

What is a specific example of competitive advantage exhibited by Darwin’s finches?(1 point)
Birds have one of two forms of the HMGA2 gene.
Female finches mated with males that had similar-sized beak
All of the finches evolved from one ancestral species and adapted to their specific niche.
Medium ground finches with small beaks survived multiple droughts.
Answer:
Explanation:
All of the finches evolved from one ancestral species and adapted to their specific niche. of them evolved from one ancestral species, which colonized the islands only a few million years ago.
Darwin's finches, which was residing in the Galapagos archipelago and Cocos island, constitute an iconic model for studies of speciation and adaptive evolution. All of the finches evolved from one ancestral species and adapted to their specific niche.
What are the characteristics of Darwin's finches?The evolutionary history of Darwin's finches is identified by a gene that explains variation in beak shape within and among species.
The major factor influencing the survival of the medium ground finches is weather and the availability of food.
As all of the finches evolved from a single ancestral species and adapted to their specific niche, it is a specific example of competitive advantage exhibited by Darwin’s finches.
Thus, the correct option is C.

Why are hydrogen bonding and popularity so important for water molecules?
Answer:
they are so important because the presence of hydrogen bonds also makes water molecules more 'sticky' or in scientific terms cohesive and adhesive. The small charges on the water molecules allows them to stick together which is why water has a 'skin' that small insects can walk on, and also explains why water can be sucked up a straw so easily.

When an infant suckles at its mother's breast, milk moves through the breast structures in what order
When an infant suckles at its mother's breast, milk moves through the breast structures in the order
Acinus - lactiferous duct - lactiferous sinus - nipple
When an infant suckles, milk is secreted from lactocytes into the alveoli (acinus). The milk is then squeezed from the alveoli so it can drain into the lactiferous ducts, milk drains from lactiferous ducts into lactiferous sinuses, and discharge through the nipple pores.
Hence, when an infant suckles at its mother's breast, milk moves through the breast structures in the order
Acinus - lactiferous duct - lactiferous sinus - nipple

Answer: The NEGATIVE CONTROL is the
test tube that is filled with ONLY distilled
water.
Explanation:
A negative control of an experiment is
carried out alongside the main primary
experiment except that the treatment is
changed to something that is predicted
to have no result. In the negative
control, the student does not expect any
response. This would help the student
compare the result of a new experiment
against an already known existing results.
Analysing the experiment carried out
by the student, She filled two test tubes
with distilled water and placed a piece
of Elodea in one of the tubes, leaving
the other without a plant. The other test
tube that contains only distilled water is
the negative control because she wasn't
expecting any result from it. It's also
served as a control sample to the primary
experiment. This is observed as she
blew in each tube to add carbon dioxide,
which caused the distilled water to
become more acidic. This would help the
student know that the that experimental
results are valid and to ensure that time is
saved
