Shakespeare, Clearly: Romeo and Juliet (one-act)

by Jon Jory

adapted from William Shakespeare

Drama

One-act. 30-35 minutes

8-30 actors

In Shakespeare's most well-known tragedy, two young star-crossed lovers’ deaths ultimately reconcile their feuding families. This straightforward adaptation mixing contemporary and classical language emphasizes story and character rather than the poetry. Master director and acclaimed playwright Jon Jory has reimagined the classic tale to serve as an early introduction for younger audiences and actors that allows easy involvement. Inventive yet faithful, this adaptation will inspire actors and audiences alike to revisit Shakespeare’s original texts. Gender-neutral casting is encouraged and doubling is possible. Simple stage allows for a fluid and forward moving production.

Procedure:

ONE ACT STRUCTURE

Set the Scene.

Introduce the character goal(s)

Introduce an obstacle to the achievement of the goal(s)

Introduce a disaster (the result of a twist if your story has one)

Oxygen is carried from systemic capillary blood to the perivascular tissues

Systemic capillary flow.

Systemic circulation blood flow help to carry oxygenated blood from the left ventricle passing through the arteries, to the capillaries in the tissues of the body. The deoxygenated blood returns from the tissue capillaries through a system of veins to the right atrium of the heart.

Therefore, Oxygen is carried from systemic capillary blood to the perivascular tissues

if temperature were available from several stations in canada near the great lakes do you think 15-degree line would form a closed loop?

Answers

Yes, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.

What is temperature?

Temperature refers to a measure of the degree of hotness or coldness of a physical body (object). Also, temperature is typically measured by using a thermometer and its units are:

Celsius (°C)Kelvin (K)Fahrenheit (°F)

What is an isotherm?

An isotherm can be defined as a line that is drawn on a map to join points with the same temperature, so as to show the distribution of temperature in a geographical region on Earth's surface.

In Meteorology, a closed loop is used to show or depict where an air mass is located when drawing isotherms. Thus, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.

how both genetic and environmental factors can affect paint color variation in california rabbits

Answers

Answer:

Coat color in rabbits is inherited as a series of multiple alleles.

Explanation:

This means that there can be more than just 2 alleles for a single gene. In the case of coat color in rabbits, there are four alleles, and each one is expressed with a different phenotype.

The genetic factors that can affect paint color variation in California rabbits are based on the several different genes that are inherited from their parents. It includes color base, color density, pattern, an extension of dark pigment, spotting, silvering, etc.

What are the genes that are responsible for color variations?

The genes that are responsible for color variations are as follows:

Gene A controls the pattern of the coat.Gene B controls the base of coat color.Gene D controls the density of the coat color.

Apart from these direct genes, several other genes are also responsible for causing variations in paint color in Rabit. The effect of environmental factors remains the same for every species regardless of competition, and other limited resources. These environmental factors govern the alteration gradually over a long period of time to stimulate some observable responses in the organisms.

Therefore, the genetic and environmental factors that can affect paint color variation in California rabbits are well described above.

how does flouride cause kidney deasies

Answers

Answer:

Hepato- and nephrotoxicity of fluoride have been demonstrated in animals, but few studies have examined potential effects in humans. This population-based study examines the relationship between chronic low-level fluoride exposure and kidney and liver function among United States (U.S.) adolescents. This study aimed to evaluate whether greater fluoride exposure is associated with altered kidney and liver parameters among U.S. youth.

This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (2013–2016). We analyzed data from 1983 and 1742 adolescents who had plasma and water fluoride measures respectively and did not have kidney disease. Fluoride was measured in plasma and household tap water. Kidney parameters included estimated glomerular filtration rate (calculated by the original Schwartz formula), serum uric acid, and the urinary albumin to creatinine ratio. Liver parameters were assessed in serum and included alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, blood urea nitrogen, gamma-glutamyl transferase, and albumin. Survey-weighted linear regression examined relationships between fluoride exposure and kidney and liver parameters after covariate adjustment. A Holm-Bonferroni correction accounted for multiple comparisons.

The average age of adolescents was 15.4 years. Median water and plasma fluoride concentrations were 0.48 mg/L and 0.33 μmol/L respectively. A 1 μmol/L increase in plasma fluoride was associated with a 10.36 mL/min/1.73 m2 lower estimated glomerular filtration rate (95% CI: −17.50, −3.22; p = 0.05), a 0.29 mg/dL higher serum uric acid concentration (95% CI: 0.09, 0.50; p = 0.05), and a 1.29 mg/dL lower blood urea nitrogen concentration (95%CI: −1.87, −0.70; p < 0.001). A 1 mg/L increase in water fluoride was associated with a 0.93 mg/dL lower blood urea nitrogen concentration (95% CI: −1.44, −0.42; p = 0.007).

Fluoride exposure may contribute to complex changes in kidney and liver related parameters among U.S. adolescents. As the study is cross-sectional, reverse causality cannot be ruled out; therefore, altered kidney and/or liver function may impact bodily fluoride absorption and metabolic processes.
