A 30-year-old male demonstrated a subtle onset of the following symptoms: dull facial expression; droopy eyelids; puffiness of the face and periorbital swelling; sparse, dry hair; dry, scaly skin; evidence of intellectual impairment; lethargy; a change of personality; bradycardia (60 b/min) low range of normal; a blood pressure of 90/70 low BP; anemia low iron – cant transport O through body very well(hematocrit 27); enlarged heart (upon radiological exam); constipation, and hypothermia. Plasma concentrations of total and free T4 and T3 follow:
Radioimmunoassay (RIA) of peripheral blood indicated elevated TSH levels. A TSH stimulation test did not increase the output of thyroid hormones from the thyroid gland.

a. What endocrine organ is involved here?
b. Is this a primary or secondary disorder? Why? (Is a TSH or TRH determination necessary for your diagnosis?)
c. Describe the feedback loop involved, indicating if there is an increased or decreased TSH level.
d. List several defects that could cause these symptoms.
e. Would you expect to find a palpable goiter? Explain your answer.
f. Describe a suitable treatment for this individual.

Answers

Answer 1

Answer:

1. Thyroid gland is the endocrine gland that is involved here.

2. TSH stimulation test did not show an increase in the output of thyroid hormones secreted from thyroid glands which makes it a primary disorder. The determination of TSH or TRH gives an idea about hypothyroidism if it is due to feedback inhibition of the pituitary or absence of TSH hormone from the pituitary, however, Circulating levels of TRH not necessary.

3.  The feedback loop involves the following:

TRH hormone secreted from the hypothalamus triggers the anterior pituitary to secret TSH that in turn triggers the relapsing of the T3 and T4 levels by the thyroid glands. If there is a low level of T3 and T4 hormones then negative feedback takes place and increases the TSH output.

4.  symptoms:

Not able to uptake the iodide into the cells of the thyroid gland

Defects in the conversion of iodide to iodine

tyrosine molecule iodization

secretion of the hormones from the Tg molecules

Less TSH receptors on the gland.

5.  The chronic TSH stimulation due to negative feedback may cause hypertrophy of the gland, results in goiter formation.

6. synthetic hormone therapy is known as Synthroid such asT4 (L-thyroxine).

Explanation:

Deadly gas. Carbon monoxide is a colorless, odorless gas that binds to hemoglobin at an oxygen-binding site. Indeed, it binds 200 times as tightly as oxygen, accounting for its toxic nature. Even if only one of the four oxygen-binding sites on hemoglobin is occupied by carbon monoxide and the remaining three are bound to oxygen, oxygen is not released. Explain.

Answers

Answer:

The binding of carbon monoxide (CO) with hemoglobin leads to an R state even in conditions that should produce the release of oxygen. In consequence, CO-hemoglobin binding shifts the oxygen dissociation curve to the left.

Explanation:

Hemoglobin is a globular protein containing four heme groups that can bind to one oxygen each. This protein (hemoglobin) has two conformational states: the T-state, also known as deoxyhemoglobin (a tense state, where lacks O species), and the R-state, also known as oxyhemoglobin (a relaxed, fully oxygenated state). When carbon monoxide binds to hemoglobin, the protein can not release oxygen, shifting the oxygen dissociation curve -which expresses the percentage of oxygen saturation against the partial pressure of oxygen- to the left. Therefore, under CO-hemoglobin binding, the oxygen level in the tissues is reduced.

Answers

In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis.

How does difference in chromosome arrangement lead to greater genetic diversity in a population?

Answers

Answer:

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Find the edge length of the cube. (The density of copper is 8.96 g/cm3, and the volume of a cube is equal to the edge length cubed.)

Express your answer with the appropriate units.

Answers

Answer:

[tex]x = 2.13\ cm[/tex]

Explanation:

See comment for complete question

Given

[tex]Mass = 87.2g[/tex]

[tex]Density = 8.96gcm^{-3[/tex]

Required

Calculate the edge length of the cube

First, we need to calculate the volume of the cube using:

[tex]Density = \frac{Mass}{Volume}[/tex]

Make Volume the subject:

[tex]Volume= \frac{Mass}{Density }[/tex]

Substitute values for Mass and Density

[tex]Volume= \frac{87.2g}{8.96gcm^{-3}}[/tex]

[tex]Volume= \frac{87.2cm^3}{8.96}[/tex]

[tex]Volume= 9.73cm^3[/tex]

Represent the edge length with x.

So:

[tex]Volume = x^3[/tex]

Substitute x^3 for Volume in [tex]Volume= 9.73cm^3[/tex]

[tex]x^3 = 9.73cm^3[/tex]

Take cube root of both sides

[tex]x = \sqrt[3]{9.73cm^3}[/tex]

[tex]x = 2.13\ cm[/tex] --- approximated

Hence, the edge length is 2.13cm

Which statement BEST explains which model accurately shows how natural selection works? que es la regla de los signos An article in The Globe and Mail, February 16, 2002, reported that IBM used the $300 million proceeds of a sale of one of its business units to reduce operating expenses in its fourth quarter 2001 income statement. This added about 8 cents per share to its fourth quarter earnings. As a result, IBM beat analysts' forecasts by 1 cent per share.IBM defended its treatment by claiming that buying and selling businesses is a normal business practice, and that most of the sale proceeds related to intellectual property that it had developed. The article quotes a Merrill Lynch analyst as saying, "Our only concern is that the company could have done more to call out the magnitude of the transaction." According to the article, IBM's share price fell by 4% as a result of this news.While not mentioned in this article, the SEC opened a preliminary inquiry into IBM's accounting practice, expressing concerns that IBM had let it be known that the reason for its higher operating earnings was tight cost controls, rather than the sale proceeds. This inquiry was subsequently dropped, but the SEC issued a bulletin reminding firms to report gains or losses on asset sales separately from operating costs.RequiredExplain why IBM's share price dropped following the Merrill Lynch analyst's comment and the news of the SEC's preliminary inquiry.
