Answer:
It is answer c
Explanation:
i know this because The epicenter is directly above the earthquake's hypocenter (also called the focus)
The phrase which describes a feature of an earthquake’s epicenter is: C. region directly above the focus.
An earthquake can be defined as a sudden, natural shaking of the ground, as a result of movements within the Earth's crust and upper mantle (lithosphere) that typically creates seismic waves.
An epicenter is the point on the surface of planet Earth, which is perpendicular to the hypocenter (focus) and it indicates where the seismic waves from an earthquake are most intense.
On a map, an earthquake’s epicenter is located at the point where the three (3) circles intersect because earthquake are generally shallow.

Explanation:
Sensory pathways are ____________ pathways that conduct information about limb ____________ and the sensations of ____________ , temperature, pressure, and pain. Stimuli received from receptors within the skin, muscles, and joints are processed through ____________ sensory pathways, while ____________ sensory pathways process stimuli received from the organs. Sensory pathways use a series of two or three neurons to transmit nerve signals from the ____________ .
Answer:
Ascending, Position, Touch, Somatosensory Pathways, Viscerosensory Pathways.
Explanation:
Sensory pathways are ascending pathways that conduct information about limb position, and the sensations of touch, temperature, pressure, and pain to the brain.
Stimuli received from receptors within the skin, muscles, and joints are processed through somatosensory pathways, while viscerosensory pathways process stimuli received from the organs.

Nancy Scheper-Hughes and Margaret Lock observed students at a teaching hospital trying to diagnose a woman's debilitating headaches. Students were impatient with the woman's description of her life circumstances, including an abusive husband and an ailing mother-in-law, but her description might BEST be termed as which of the following?
a. an illness narrative
b. a biomedical diagnosis
c. the human microbiome
d. alternative medicine
Answer:
The answer is option A.
Explanation:
An illness narrative is defined as "patients’ stories about their experiences of illness" on Oxford Medicine. According to the information given in the question, she is telling her experience in an autobiographical fashion with the environmental details, description and other things that may affect her situation, so her description can be best categorized as an illness narrative. The answer is option A.

Serratia marcescens bacteria has a gene that regulates red pigment production by cells. A student inoculates two nutrient agar plates of Serratia and incubates one at 250C and the other at 370C. Following incubation, the student observes that colonies on the 250C plate are red while those on the 370C plate are nonpigmented.
Which of the following statements is a logical conclusion based on these results?
A. Low temperatures cause repression of certain housekeeping genes.
B. Serratia cells undergo a genotypic change that is proportional to changes in temperature.
C. This is an example of constitutive gene expression.
D. Serratia genes for pigment production are induced at certain temperatures.
Answer:Serratia genes for pigment production are induced at certain temperatures
Explanation:
The red pigment production is dependents on temperature.
Some bacteria are thermophile doing very well in extreme temperature while some are very sensitive to temperature changes.
The red pigment production is regulated by certain gene in the bacteria but can only be activated at certain temperature. 25°C was suitable for the red pigmentation that is why the plate color changed this indicate the sensitivity of the pigment production to temperature changes.
Conclusion - To get the best of serratia it is best to keep them at a temperature lower than the normal room temperature for the gene to be activated and full express itself.
2. a) What is gene flow? (3 points)
) v
b) How does gene flow affect the fitness of a population? (2 points)
3. a) What is an index fossil? (2 points)
Answer:
Gene flow is the transfer of genes in and out of a population.
2. Geneflow affect the fitness ofva population.
Gene flow within a population can cause an increase in the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations.
Index fossil is any animal or plant preserved in the rock record of the Earth that is use to identify and gate geologic periods.
Explanation:
Gene flow is the transfer of genes or genetic variation in and out of a population.
Gene flow is cause by movement of organisms that reproduce in their new population or movements of gametes. For example, when bees carry pollen from a flower in one location to flowers in another location, the bees are causing gene flow.
Gene flow within a population can cause an increase in the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations. Thereby affecting it's genetic fitness.
Index fossil is any animal or plant preserved in the rock record of the Earth that is use to identify and gate geologic periods. Examples of index fossils include: Ammonites were common during the Mesozoic Era (245 to 65 mya
