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.
Answer:
the reporter gene can randomly insert near to an enhancer sequence which can induce its expression
Explanation
Enhancers are genetic sequences capable of activating gene expression by binding to specific proteins (e.g., transcription factors). Enhancers can regulate the expression of nearby genes located thousands of nucleotides away, i.e., over several kilobases away. In the human genome, it is well known that enhancers are scattered across the 98% of the genome. In this case, it is expected that the reporter GFP gene construct is randomly inserted near an enhancer sequence (a 10% chance of insertion), thereby being regulated by that enhancer.
Answer: Survival rate up to start of April = 76.67%
Explanation: size of colony = 150mice.
Size of colony in February =125mice.
Size of colony in march = 115 mice.
1. Survivorship rate in February
= Size of colony / size in February *100.
= 122 / 150 * 100
= 83.33% to the nearest hundredth
2. Survivorship rate in march
= Size of colony / size in march *100.
= 115/150 * 100
= 76.67% to the nearest hundredth.
Answer:
my best guess would be d. genetic
Explanation:
because genetic diversity measures genetic variation within species.
