Answer: The pathology described in the question is "testicular torsion".
The most sensitive physical exam that is specific to this pathology is testing for reflexes. The inner thigh of the affected side when rubbed should cause the testicle to contract; but in this pathology, it does not.
Explanation:
Testicular torsion is a condition caused by the twisting of the spermatic cord, which causes a loss of blood flow to the testicle. It is the leading cause of testicular loss in adolescent boys, if no surgical intervenvention is carried out as soon as possible.
Organs, cells with the same function make up tissue and tissue makes up the organ
Answer:
Sympatric speciation.
Explanation:
Sympatric speciation occurs between Crematogaster ashmeadi and Linepithema humile ants because they live on the same geographical location. Sympatric speciation is a type of speciation in which ancestral population evolve into separate species without separation of geography. Hybrid sterility is the postzygotic isolating mechanism that decreases the fitness of the hybrid individuals and helps in controlling the population of an organisms..
If thousands of glucose molecules were bonded together with equal numbers of sucrose molecules, the resulting substance could be described as a polysaccharide. They are <span>polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages.</span>
<span>Let the equation be : at^2 + bt + c = P,
where t = time (hrs),
P = population (1000's).
When t = 1, P = 3.03.
When t = 2, P = 1.72.
When t = 3, P = 1.17.
Substitute these into the equation to obtain these 3 simultaneous equations :
a + b + c = 3.03
4a + 2b + c = 1.72
9a + 3b = c = 1.17
Solving gives :
a = 0.38,
b = -2.45,
c = 5.1.
The equation is therefore,
P = 0.38t^2 - 2.45t + 5.1
Testing with t = 0 to 6 gives the population values as provided,
so it seems to be a valid model.
At t = 9 hrs,
P = 0.38*9^2 - 2.45*9 + 5.1
= 13.83.</span>
