The following case study is a paraphrase from "Good Clinical Practice. Standard Operating Procedures for Clinical Researchers" (Kolman, J., Meng, P. and Scott, G. editors; John Wiley and Sons publishers, 1998):
“While a study subject and a relative were walking in town one day during the summer, a hanging flower basket fell on a study subjects head, resulting in the study subject falling down and becoming unconscious. The subject’s relative called for an ambulance. On arrival at a local hospital’s Emergency Department, in which the subject regained consciousness but could not recall the event, a x-ray revealed a fractured skull. The subject’s consciousness level at this point was deteriorating and after further tests a subdural hematoma was diagnosed, which was evacuated under general anesthesia. Postoperative recovery was uneventful and progressing well until day four, when the patient developed acute dyspnea (shortness of breath) at rest during visiting time. An emergency lung scan was performed that confirmed a diagnosis of pulmonary embolism. The study subject was anticoagulated and was eventually discharged from the hospital”

why is it so important for animals to keep the concentration of their body fluids constant
Answer:
A balance of bodily fluids will prevent the development of diseases, the deterioration of body organs, and death of animals.
Explanation:
Water, blood, saliva, sweat and other body fluids should be kept constant and balanced through homeostasis because the sharp rise and fall of these fluids will prevent the organs of the body from operating optimally and this can lead to the development of diseases and consequent death. For example, water is a vital fluid. Too much of water in the system can lead to diseases like Edema where the legs begins to swell because there is no way of letting out body fluids from the body.
Too little water in the body can lead to dehydration and the increase in blood pressure because of the excessive concentration of solutes. The digestive and urinary systems have mechanisms to keep this fluid under control.
What two elements are used in carbon dioxide
Answer:
1 carbon atom and 2 oxygen atoms
Explanation:
Answer:
Carbon dioxide, CO2, is a chemical compound composed two oxygen atoms covalently bonded to a single carbon atom.
Explanation:
Assume that gene A controls the conversion of a white pigment, P0 into another white pigment, P1 the dominant allele A specifies an enzyme necessary for this conversion, and the recessive allele a specifies a defective enzyme without biochemical function. Gene B controls the conversion of the white pigment, P1 into a pink pigment, P2 the dominant allele, B, produces the enzyme necessary for this conversion, and the recessive allele, b, produces a defective enzyme. The dominant allele, C, of the third gene specifies an enzyme that converts the pink pigment, P2 into a red pigment, P3 its recessive allele, c, produces an altered enzyme that cannot carry out this conversion. The dominant allele, D, of a fourth gene produces a polypeptide that completely inhibits the function of enzyme C; that is, it blocks the reaction P2-P3 Its recessive allele, d, produces a defective polypeptide that does not block this reaction. Assume that flower color is determined solely by these four genes and that they assort independently. In the F2 of a cross between plants of the genotype AA bb CC DD and plants of the genotype aa BB cc dd, what proportion of the plants will have (a) red flowers? (b) pink flowers? (c) white flowers?
Answer:
Red = 27/256Pink = 117/256White = 112/256Explanation:
Available data:
Four diallelic genes: A, B, C, DAA and Aa allows the conversion of P0 tp P1, while aa does notBB and Bb allows the conversion of P1 tp P2, while bb does notCC and Cc allows the conversion of P2 tp P3, while cc does notDD and Dd inhibit the action of allele C (P2 to P3), while dd does notThis is:
In the presence of the dominant alleles A, B, and C, the three might occur:
Po (white 0) ----> P1 (White 1) ----> P2 (Pink)----> P3 (Red)
A B C
In the presence of the recessive alleles a, b or c, the three reactions or some of them might not occur ( the X represents the inhibition of the reaction):
Po (white 0) --X--> P1 (White 1) --X--> P2 (Pink)--X--> P3 (Red)
a b c
In the presence of allele D, the last reaction is not possible, because D inhibits the action of C
P2 (Pink) --X-->P3 (Red)
C + D
So, in order to get Red flowers we must have the next genotype: A-B-C-dd (The three reactions can occur, and D must be absent)To get Pink flowers we must have the next genotypes: A-B-C-D- (D Inhibits C, hence it inhibits the third reaction) or A-B-ccD- or A-B-ccdd (cc does not allow the third reaction to happen, independently of the D gene presenceTo get White flowers we must have the next genotypes: aaB-C-D-,aabbC-D-, aaB-ccD-, aabbccD-, aabbccdd, aaB-C-dd, aaB-ccdd, aabbC-dd, A-bbC-D-, A-bbccD-, A-bbC-dd, A-bbccdd (aa must be present to get a white0 flower, or bb must be present to get a white1 flower)In the proposed problem, we have that the parental are AAbbCCDD and aaBBccdd, so we can tell that the whole F1 progeny will be heterozygous for the four genes, this is AaBbCcDd.
Knowing that these four genes assort independently, then we can infer that the F2 will have the next genotypic proportions for each gene:
AA + Aa=3/4aa= 1/4BB + bb= 3/4bb = 1/4CC + Cc = 3/4cc= 1/4DD + Dd =3/4dd= 1/4So, to get each of the mentioned genotypes for each trait, we must multiply their respective genotypic proportions, like this:
Red: A- x B- x C- x dd: 3/4 x 3/4 x 3/4 x 1/4 = 27/256Pink: A- x B- x C- x D-: 3/4 x 3/4 x 3/4 x 3/4 = 81/256A- x B- x cc x D-: 3/4 x 3/ x 1/4 x 3/4 = 27/256
A- x B- x cc x dd: 3/4 x 3/4 x 1/4 x 1/4= 9/256
By summing these proportions, we can get the proportion of all the pink flowers: 27/256 + 81/256 + 27/256 + 9/256= 117/256
White: To get the proportion of white flowers, you can repeat the same multiplications as before for each possible white genotype and then sum the results, as we did for pink flowers. Or you can extract from the total number of flowers (256), the amounts of red and pink flowers (27 and 117). This is: 256 - (27 + 117) = 112.Then 112/256 is the proportion of white flowers.

Write a function that gives the car's value, V(t)V(t)V, left parenthesis, t, right parenthesis, ttt years after it is sold.
Answer: V(t)=5000(9/10)^t
Explanation:
If the car loses 1/10 of its value each year, that means 9/10 of the value remains each year.
So each year, the car's value is multiplied by a factor of 9/10 or 0.9
If we start with the initial value, $5000 and keep multiplying by 9/10 his function gives us the car's value t years from now:

Answer: funcrion- The male reproductive system is a grouping of organs that make up a man's reproductive and urinary systems. These organs do the following jobs within your body: They produce, maintain and transport sperm (the male reproductive cells) and semen (the protective fluid around the sperm). Aging changes in the male reproductive system occur primarily in the testes. Testicular tissue mass decreases. The level of the male sex hormone, testosterone decreases gradually. ...

Explanation:
What are the gametes that would be formed for the following genotype: Aa?
Answer:
A and a
Explanation:
GAMETE formation occurs via a process called MEIOSIS. During meiosis, segregation and independent assortment of genes occur. According to Gregor Mendel who proposed the law, the law of segregation states that the alleles of a Gene will separate into gametes. This separation occurs in such a way that only one allele of that gene is found in each gamete.
In this case, an organism with genotype "Aa" will produce gametes that contains the following: A and a. Therefore, the gametes of genotype Aa will be A and a.
