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.

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.

Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if one dog is true-breeding for the long-coat trait and the other dog is true-breeding for the short-coat trait. ResetHelp
Answer:
100% long-coat
Explanation:
Assuming that the long-coat trait is represented by L allele and the short-coat trait by l allele.
True-breeding long-coat dog would have the genotype LL while true-breeding short-coat would have the genotype ll.
Assuming that the long-coat trait is dominant over the short-coat trait.
LL x ll
Ll Ll Ll Ll
All the offspring would have Ll genotype and would appear with long-coat phenotypically. Hence, the proportion of offspring phenotypes is 100% long coat.

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.

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 trait for tall pea plants is (T) and the trait for short pea plants is (t). The trait for smooth pea plants is (R) and the trait for wrinkled is (r).Two plants are crossed producing a F1 generation of plants with 612 tall and smooth pea plants and 188 short and wrinkled pea plants.What would be the most likely genotype of the parental generation?
Answer:
P generation = TtRr × TtRr i.e both parents were heterozygote for both traits
Explanation:
This question involves two genes encoding the height and texture in pea plants respectively. The alleles for tall and smooth pea traits are dominant over the alelles for short and wrinkled traits.
According to this question, two plants are crossed to produce F1 offsprings as follows: 612 tall and smooth pea plants and 188 short and wrinkled pea plants.
First, we turn this derived number of offsprings into ratio by dividing by the smallest number (188)
612/188 : 188/188
3.25 : 1
Approximately; we can say this is 3 (tall and smooth) : 1 (short and wrinkled)
Based on this ratio, which was got by Mendel for his F1 offsprings when he crossed pea plants, the parental generation has a heterozygous genotype (TtRr).
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.

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
A membrane is a thin layer which forms the wall of the cell and typically controls what leaves and enters the cell.
Some of the effects of various biological conditions on membrane physiology are;
1. Makes RMP (Resting Membrane Potential) Less Negative: this simply means that it decreases RMP;
Decreased concentration of leaky potassium channels in the membrane. ATP stores are declining through mitochondrial poison (arsenic). Increased concentration of leaky sodium channels in the membrane.2. Influences the Ability of the Cell to Repolarize;
Voltage regulated potassium channels are blocked. Acetylcholine esterase concentration is decreased.3. Influences the Ability of the Cell to Depolarize;
The size of the synaptic cleft is increased. Hyperhydration (high water concentration in ECF). Release of excitatory neurotransmitter by a presynaptic input is blocked. Hyponatremia (low ECF sodium).Neurotransmitter synthesis is compromised due to Golgi dysfunction in the presynaptic neuron.It is one of the most important step in conducting a survey by knowing the environmental concerns such as potential noise, air and water pollution.
