Chemicals given off by the systemic capillary blood to the perivascular tissues often include which of the following?
Glucose
Ammonia
Antibodies
O Oxygen
Hormos
Carbon dioxide
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

Flower Dissection - Part 2
• Pick a flower from your yard, a public location, or somewhere in your neighborhood.
• Start by removing the sepals of the flower with a tweezer. If you do not have a tweezer, a small pair of scissors will also work. It may be easiest to do this if you hold the flower with your finger from below the pedicel (small stalk just underneath the flower) and begin to remove the sepals with a pair of tweezers.
• Using tweezers, place the sepals on the labelled printable worksheet, and tape them in place.
• Repeat the same procedure for the petals and pistil.
• Remove all but one of the stamens and tape them onto the worksheet.
• On your printable worksheet, you should have sepals, petals, stamens and one pistil.
• Take a picture of your worksheet with the flower pieces placed correctly, and save it on your computer. You will attach and submit this with your assessment questions.

5. Based on your knowledge of flowers, why do you think most flowers are bright in color?
The plant is made up of root and shoot structures that contain parts that enable the plant to grow and manufacture its food.
The structure and function of plantsThe structure of plants is made up of tissues such as:
phloemstomaxylemguard cellsdermalground andvascular.The three characteristics that all species being to the plant kingdom have in common are:
They are non-motile,They make their food hence are called autographs; andTheir cell walls are made sturdy by a material called celluloseThe tropical plants have more stomata than the desert plants. This helps the desert plants to reduce water loss.
Some defects occur when there is damage to the vascular tissues such as the xylem( plant will not be able to transport water from the soil through roots to leaves) and phloem (nutrients produced during photosynthesis will not be able to reach every part of the plant body).
The dermal tissue of plants and the human skin performs protective roles to the underlying tissue organs.
A plant won't be able to survive because it won't absorb water and nutrients from the soil and transport it upwards to all the parts of the plant.
Flowering reproduction in plants takes place through the following steps:
Pollen is carried by insects or blown by the wind from one flower to another. This process is called pollination. Pollen reaches the new flower and travels to the ovary where it fertilises egg cells (ovules) to make seeds. This is fertilisation.Flowers benefit other organisms in our environment by creating more carbon dioxide-absorbing and oxygen-radiating plants.
The flowers contain male reproductive organs called stamens and female reproductive organs called pistils.
The process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote.
Most flowers are bright in color because they are like advertisement signs for pollinators.

One Act Example
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)

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