A researcher is keeping tabs on a population of butterflies in Southern California. The species being studied is commonly known as Gossamer-Winged butterflies. These butterflies can have copper tipped wings (dominant trait) or blue tipped wings (recessive trait).
Butterflies, like many organisms, are sensitive to changes in their habitat. This particular population of butterflies being studied has had
significant changes to their habitat in recent years due to drought. In order to keep track of the population, the researcher counts the
number of copper versus blue tipped wings in the population every two years and collects DNA samples to keep track of allele
frequencies. The chart below represents the data he collected in 2017 (day 1) and 2019 (day 730).

Using the data in the chart above you will answer parts a-d. Show all work on paper you will need to email this. This spot is strictly for
your final answers:
a. Calculate the three observed genotypic frequencies at day 1.
b. Calculate the three expected genotypic frequencies at day 1 IF the population were in Hardy-Weinberg equilibrium.
c. Calculate and compare the observed genotypic frequencies to the expected genotypic frequencies at day 730. Does the
population of Gossamer-Winged butterflies seem to be evolving?
Observed genotypic frequencies:
Expected genotypic

Null Hypothesis:
Observation:
d. To add validity to your hypothesis in part (C) complete the Chi Square analysis. What does this result mean for the Gossamer-
Winged butterfly population?

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
