A 47 year-old male presents with chronic back pain and lower left leg radiculitis. A laminectomy is performed on the inferior en
Morgarella [4.7K]

The correct codes are 63267 and 69990.

The codes are given based on the lesion if it is intradural or extradural. In our case here it is extradural cystic structure so that is why it ranges between 63265 to 63268.

We also divide the section of spine depending on where the lesion is being located. Code 63267 describes laminectomy which has evacuation of intraspinal lesion which is found in the lumbar spine.

69990 code documents the use of microscope.

In corn, red kernel color (R) is dominant to yellow (r) and smooth kernel texture (W) is dominant to wrinkled (w).
Wewaii [24]

Answer:

a. df =  3, chi-square = 1.7333, p value = 7.815

b. we fail to reject null hypothesis

c. it is independent of kernel texture

Explanation:

h0; there is independence

h1; no independence

9:3:3:1 this is the phenotypic ratio

9+3+3+1 = 16

330 red smooth  + 97 red wrinkled  + 101 yellow smooth  + 32 yellow wrinkled

total observed = 560

1. the degree of freedom = n-1

n =4, 4-1 = 3

to get the chi square computation

(O-E)²/E

expected value for red smooth,

9/16 x 560 = 315

chisquare = (330-315)²/315 = 0.7143

expected for red wrinkled

3/16*560 = 105

chisquare = (97-105)²/105 = 0.6095

expected for yellow smooth

3/16*560 = 105

chisquare = (101-105)²/105 = 0.1524

expected for yelow wrinkled

1/16 * 560 = 35

chisquare = (32-35)²/35 = 0.2571

total chisquare = 0.7143+0.6095+0.1524+0.2571

= 1.7333

with probability = 0.05, df = 3, the value of the chi square from x² table = 7.815

1.7333 < 7.815

so  we fail to reject the null

c. we conclude that kernel color is independent of kernel texture

A person whose body is not producing enough testosterone is most likely to exhibit
creativ13 [48]

Answer:

The symptoms that a person with low testosterone would exhibit: fatigue, irritability, low sex drive, low strength, erectile dysfunction, hair loss, amongst others.

Explanation:

When the body is not producing enough testosterone, that is, low levels of testosterone -a very important sex hormone- it leads to a condition called male hypogonadism.

Depending on the age of the person, the male exhibits different symptoms. The most common ones are:

  • Fatigue
  • Irritability; mood changes; depressive symptoms
  • Low sex drive
  • Erectile dysfunction
  • A reduction in the strength of the body
  • Hair loss

This condition could be the result of different factors, such as <u>aging, chemotherapy, increased alcohol levels, radiation</u>, and diseases or syndromes such as <u>HIV, Kallman syndrome, hypothyroidism</u>.
