I will report your answer if you don't answer this seriously and just want points answer wisely Natural Selection in Populations
This activity will help you meet these educational goals:

You will use mathematical representations of phenomena to describe and support claims and explanations.
You will analyze data using tools and models in order to make valid and reliable scientific claims.
You will apply concepts of statistics to scientific questions and problems, using digital tools when feasible.
Directions
Read the instructions for this self-checked activity. Type in your response to each question, and check your answers. At the end of the activity, write a brief evaluation of your work.
Activity
In this activity, you’ll analyze and interpret data about a population. A scientist has been monitoring the height of a small population of wild sheep for 30 years. He monitored 200 adult male sheep from each year, and then broke down their height into ranges. Study the data in the chart, and then answer the questions that follow.

Height Less than 1 m 1 m – 1.19 m 1.2 m – 1.4 m Greater than
1.4 m
30 Years Ago 45 110 40 5
Present Data 15 84 75 26
Distribution of height

Height
Part A
Question
Using the data in the table, make a bar graph that shows the distribution of height for the sheep both 30 years ago and today.

Part B
The researcher thinks the changes in data are a result of selection. Do you think directional, disruptive, or stabilizing selection is occurring? How does your data support this conclusion?

Part C
What percentage of sheep had a body height of 1.2 meters or more 30 years ago? How does it differ from the present data? Does this data support your argument regarding the type of selection occurring?

Part D
The researcher also collected height data from 200 female sheep during both years but didn’t notice a significant difference in height. What could this data suggest?

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
