(highlight your chosen answer) i. One categorical ii. Two categorical iii. One numeric iv. One numeric and one categorical v. Two numeric b.What is your experimental hypothesis? c. What is your attentive hypothesis? d. What is your null hypothesis?

The legend from figure 1 includes all of the following information EXCEPT: a. the error bars represent the standard error b. the number of replicates (n) c. a brief explanation of the experiment design d. which pH level caused the greatest delay in egg laying egg laying time (h) 56- 54- 52- 50- 55 54 54 3.13 3.33 4.33 53 5.33 52 6.33 53 7.33 53.7 54 8.33 9.33 53.3 10.33 54 11.33 pH FIGURE 1 | Egg laying time in different pH environments. Thirty-five newly hatched L1 were cultured at specific pH medium. The earliest observed egg laying time on each plate was recorded. Error bars represent the standard error from three replicated experiments.

Probability sample has the following.17 : characteristics except one a. It is not good representative sample b. It is the best c. Representative d. Generalise O

Suppose a researcher is investigating the measurement ability of a new device intended to read the freezing point of a chemical compound. The substance used in the investigation has a known freezing point of -24 degrees Celsius. The researcher conducted a series of 10 sample measurements of the freezing point, and the results are represented below. What can we say about the device with regards to its precision, and potential bias?   Measurement Freezing Point (degrees Celsius) 1 -26 2 -18 3 -32 4 -31 5 -24 6 -24 7 -24 8 -24 9 -11 10 -37

1. As you finish up your 15th week of class, I would like for you to create a new "biology concept map" connecting the BIO 001 Lecture Topics to Biology Core Concepts. a. In the box provided below, connect the BIO 001 Lecture Topics listed below. Draw boxes around each topic and lines to connect the topics to each other. Draw as many lines as you see fit. b. On each line, write an action word or phrase that describes how the topics are connected (e.g., energy might be connected to grow by the phrase "organisms need energy to grow"). c. Draw circled numbers 1, 2, 3, or 4 next to the BIO 001 Lecture Topics that you think fit into each of the Biology Core Concepts listed below. You may use each of the biology core concepts multiple times or you may not use one of them. BIO 001 Lecture Topics: Population and Community Ecology Community and Ecosystem Ecology Ecosystem Ecology Conservation Biology and Biodiversity Cells Mitosis and Meiosis Genetics and Evolution Population Genetics…

A student transplants four plants and measures their heights. For the next month, the student gives the plants different amounts of water. After one month, the student measures the height of the plants again. Height At End (cm) Amount of Amount of Height at Start (cm) Water Weekly Sunlight Daily (L) (hrs) Plant 1 0.7 8. Plant 2 0.1 8 Plant 3 0.5 8. 6.5 Plant 4 0.3 85 8 5555

What is the distribution of the model that we can use for this hypothesis test? A.t with 45 degrees of freedom B. z, the standard normal distribution O C.t with 44 degrees of freedom

This is data that my group (Gr3) got after doing an experiment. I will give you some context so you know what to do. D1 D2 D3 and so on stand for the density of P.c. alone, P.a. alone, P.c. mix, P.a. mix on different days all the way to day 9. We tested 3 vials 3 times each day so each separate table is a different vial. we were using 10ml of medium (water) in the vials and we would count the number of these cells each day in .1 ml of sample. P.c. alone stands for # of paramecia caudatum in a vial with only paramecia caudatum. P.a. alone stands for # of paramecia aurelia in a vial with only paramecia aurelia. P.c. mix stands for # of paramecia caudatum in a vial with both aurelia and caudatum. P.a. mix stands for # of paramecia aurelia in a vial with both aurelia and caudatum. All I need you to do is create 3 different types of graphs based on the data (line, column , pie, bar) you can choose whatever just don't make a table.

Drug A is being tested for its effectiveness in easing menopause symptoms. In designing an experiment to test Drug A, which of the following would be a valid approach? a. Participants can choose whether to be in the experimental or control group. b. The experimental group will contain only females and the control group will contain only males. c. Unlike the experimental group, the control group should include subjects whose age is above 52 years. d. The experimental group will receive Drug A and the control group will receive a placebo.

Pretend you are performing an experiment with a pigmented substance similar to BPB. As the concentration increases, the color of the liquid in the container intensifies. a. How can you use a standard curve to compare the color of your samples? b. What is going the standard curve look like? What are you going to have on your X and Y axes?  c. Is your standard curve always be the same if you use the same pigment and the same concentration?
