Collect data: Blood carries many vital substances. Four of these are listed above the Microscopic view. Oxygen and sugar are needed by all body cells. Carbon dioxide and urea are waste products. What are the concentrations of each substance in this sample?
Oxygen:
Carbon Dioxide:
Sugar:
Urea:
Answer:
Explanation:
in the given sample of blood concentration of all the comonents is normal. the concentration of urea is 2.6 to 6.5 mM, concentration of carbon dioxide is 23-29 meq/L, while concentration of glucose ad oxygen are 0.9 g and 20.1 ml respectively.
Blood is the component of the circulatory system which is essential for the transport of gases and excretion of waste products. It is crucial for nutrient and oxygen supply to the body.
The concentration of oxygen was 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.
The vital substance of blood can be explained as:Red blood cells are called erythrocytes that are responsible for oxygen transportation through the hemoglobin component to the body parts while on their way back it carries the carbon dioxide.Sugar is the major form of energy needed by the body for functioning which enters the blood from the liver.Urea is the waste complement removed with the help of blood collected from the liver and excreted by kidneys.Therefore, the normal concentration of blood substances is oxygen 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.

What is chemical water pollution?Chemical water pollution refers to the presence of harmful chemicals or substances in water bodies such as lakes, rivers, and oceans. These chemicals may come from various sources, including industrial processes, agriculture, and human activities. Common types of chemical pollutants in water include heavy metals, pesticides, oil spills, and toxic waste.
Chemical water pollution can have harmful effects on the environment and human health, including reduced water quality, contamination of aquatic life, and the spread of waterborne diseases. Preventative measures, such as proper waste disposal and treatment, are necessary to minimize chemical water pollution and protect water resources.

F. Oxytocin
G. Antidiuretic hormone (ADH) or vasopressin
H. Follicle-stimulating hormone (FSH)
I. Thyroxine (T1)
J. Calcitonin
Answer:
A. Growth hormone- anterior pituitary
Prolactin - anterior pituitary
Adrenocorticotropic hormone- anterior pituitary
Thyrotropic hormone- anterior pituitary
Luteinizing hormone - anterior pituitary
Oxytocin - hypothalamus
Antidiuretic hormone - hypothalamus
Follicle-stimulating hormone- anterior pituitary
Thyroxine (T1) - thyroid gland
Calcitonin - thyroid gland
Explanation:
The growth hormone is released from the anterior pituitary gland. The hormone acts on many parts of the body and promotes growth especially in children.
The hormone prolactin is produced in the anterior pituitary gland during pregnancy in order to develop breast tissues and prepare for milk production.
Adrenocorticotropic hormone (ACTH) helps the body to respond to stress conditions. It stimulates the production of cortisol from the adrenal gland.
TSH is produced by the pituitary gland and controls the production of the thyroid hormones.
Luteinizing hormone is one of the hormones produced by the pituitary gland.
Oxytocin is produced in the hypothalamus and is secreted into the bloodstream directly. It is important in female reproduction and is produced in large amount during labor. It is also released when the nipples are stimulated.
Antidiuretic hormone controls of the amount of water lost via urine. It is produced in the hypothalamus.
Follicle-stimulating hormone is another hormone produced by the pituitary gland. It plays an important role in sexual development especially in women where it controls the menstrual cycle and assists in the growth of eggs.
The thyroid gland produces many thyroid hormones including T1,T2,T3 and T4.
The thyroid gland also produces calcitonin, a hormone secreted by the thyroid gland and regulates the amount of calcium in the blood.
How does the carrying capacity of the ecosystem for the white footed mouse respond to the changes in the amount of parasites? Compare graph 1 and graph 2 to help you answer the question, cite the data to support your answer (give numbers)
Answer:
See the answer below
Explanation:
The carrying capacity of the ecosystem for the white-footed mouse reduced in response to the changes in the amount of worm infected mice in the population.
The carrying capacity of an ecosystem for a particular population of organisms is the maximum number of organisms the ecosystem can support based on the resources it has.
The ideal carrying capacity of the ecosystem for the white-footed mouse oscillates between 36 to 40 in graph 1. The carrying capacity range reduced in graph 2 from 36 - 40 to 30 - 36 as a result of changes made to the number of mice infected with parasitic worms in the population of the animal.
Thus, the introduction of more worm-infected mice into the population probably put more pressure on the ecosystem resources thereby reducing the carrying capacity.

The Jules Verne novel "20,000 Leagues Under the Sea" tells the story of the voyage of the submarine Nautilus. If one league equals 3 miles, how many kilometers did the Nautilus travel on its journey? Please round your answer to the 100's place
Answer:
96558.00 kilometers
Explanation:
From the title of the novel, it is assumed that the submarine covered 20,00 leagues on its journey.
1 league = 3 miles, therefore;
20,000 leagues = 20,000 x 3 = 60,000 miles.
1 mile = 1.6093 km
Hence,
60,000 miles = 60,000 x 1.6093 km
= 96,558 km
= 96558.00 km to the 100's place
Therefore, 96558.00 kilometers was covered by Nautilus during the journey.

55.7 moles of PCl5 will decompose to produce how many moles of PCl3 and Cl2 combined ?Enter your answer correct to 1 decimal place
Answer:
55.7 moles of PCl₃ and 55.7 moles of Cl₂
Explanation:
The balanced chemical equation for the reaction in which phosphorus pentachloride (PCl₅) is decomposed in phosphorus trichloride gas (PCl₃) and chloride gas (Cl₂) is the following:
PCl₅(g) → PCl₃(g) + Cl₂(g)
According to the stoichiometric coefficients, 1 mol of PCl₅ produces 1 mol of PCl₃ and 1 mol of Cl₂. So, the stoichiometric ratios reactant/product are: 1 mol PCl₃/1 mol PCl₅ and 1 mol Cl₂/1 mol PCl₅. Thus, we multiply the stoichiometric ratios by the number of moles of reactant:
1 mol PCl₃/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol PCl₃
1 mol Cl₂/1 mol PCl₅ x 55.7 mol PCl₅ = 55.7 mol Cl₂
Therefore, 55.7 moles of PCl₃ and 55.7 moles of Cl₂ are obtained from the decomposition of 55.7 moles of PCl₅.

20. Edward Lambert, an Englishman, was born in 1717. Lambert had a skin disorder characterized by very thick skin that was shed periodically. The hairs on his skin were very coarse, like quills, giving him the name "porcupine man." Lambert had six sons, all of whom exhibited the same traits. The trait never appeared in his daughters. In fact, the trait has never been recorded in females. Provide an explanation for the inheritance of the "porcupine trait
Answer:
The trait is Y-linked
Explanation:
The only plausible explanation behind the inheritance pattern shown by the porcupine trait is that it is Y-linked.
Y-linked traits are limited to the Y chromosome only, a sex chromosome that is peculiar to only the male gender. Chromosomally, females are XX while males are XY. Hence, only the male gender has the genetic capacity to inherit the porcupine trait. This is why only the sons of Edward Lambert, and never the daughters, exhibited the trait.
