One typical human skeleton includes all of the following except…
A. 20 middle phalanges.
B. 22 long bones that lack landmarks called “heads” of those bones.
C. 86 bones that are classified as flat or irregular bones.
D. 7 flat bones that are part of the pectoral girdle or pelvic girdle.
E. If all of the above are true, choose this response.
At one instant a bicyclist is 38.0 m due east of a park’s flagpole, going due south with a speed of 14.0 m/s. Then 23.0 s later, the cyclist is 38.0 m due north of the flagpole, going due east with a speed of 14.0 m/s. For the cyclist in this 23.0 s interval, what are the (a) magnitude and (b) direction of the displacement, the (c) magnitude and (d) direction of the average velocity, and the (e) magnitude and (f) direction of the average acceleration? (Give all directions as positive angles relative to due east, where positive is measured going counterclockwise.)
A car is traveling at 26 m/s when the driver spots a large pothole in the road a distance 34 m ahead. She immediately applies her brakes. If her acceleration is -7.5 m/s2, does she manage to stop before reaching the pothole?
Below, is the full question, however I am having trouble with the “close_novas.sample…” section of bootstrap_ages, please help.
Question 9 It’s time to bootstrap so that we can quantify the variability in our estimate! Simulate 1000 resamples from close_novas. For each resample, compute the slope of the least-squares regression line, and multiply it by 1 million to compute an estimate of the age of the universe. Store these ages in an array called bootstrap_ages, and then use them to compute a 95% confidence interval for the age of the universe.
bootstrap_ages = make_array()
for i in np.arange(1000):
bootstrap_ages = np.append(bootstrap_ages, 1e6*fit_line(close_novas.sample
lower_end = percentile(2.5, bootstrap_ages)
upper_end = percentile(97.5, bootstrap_ages)
Table().with_column(“Age estimate”, bootstrap_ages*1e-9).hist(bins=np.arange(12, 16, .1), unit= “billion years”)
print(“95% confidence interval for the age of the universe: [{:g}, {:g}] billion years”.format(lower_end*1e-9, upper_end*1e-9)
Can you please help me find scholarly articles concerning the following questions:
Give a detailed description of the use of chi-square test as a measurement in biological research. Give its application
The recessive allele s causes Drosophila to have small wings and the s + allele causes normal wings. This gene is known to be X-linked.
a. If a small-winged male is crossed with a homozygous wild-type female, what phenotypic ratio of normal to small-winged flies can be expected overall and by each sex in the F1? Show the Punnet square.
b. If F1 flies are intercrossed, what F2 progeny phenotypic ratios are expected overall and by sex Show the Punnett square.
c. What progeny phenotypic ratios overall and by sex are predicted if F1 females are backcrossed to their father? Show the Punnett square.
