If a person had not drunk any water for 8 hours before collecting a sample, would you expect his/her urine to have a high or low specific gravity? Why?
Answer:
The person’s urine will have a high specific gravity
Explanation:
A high specific gravity is characterized by an increased concentration of solutes in the urine of am individual. A low specific gravity is characterized by a low or decreased concentration of the solutes.This is usually due to dehydration as a result of environmental conditions or tedious physical activities.
This explains why a person who had not drank any water for 8 hours and is dehydrated before collecting a sample is thought to have a urine with a high specific gravity
HEEELLLPPP PLSS!!! Compare and contrast open, closed, and isolated systems. Be sure to discuss the exchange of energy and exchange of matter, and provide at least one example of each.
Answer:
See the answer below
Explanation:
An open system is a type of thermodynamic system in which energy and matter are being exchanged between the system and the surrounding. It is like boiling soup in an open pot. The opening allows for the addition of materials (matters) into the soup and energy is exchanged through the heating. A good example is found in biological organisms. They consume matters and exchange energy with the environment by carrying out work.
A closed system is a type of system in which there is no exchange of matter between it and the environment. However, there is an exchange of energy. It is like boiling water in a closed pot. Nothing can be added into the pot due to the closure but energy can be transferred through the heating of the pot.
An isolated system allows for neither energy nor matter exchange with the surrounding. It is like a closed food warmer that allows for nothing to enter or leaves it.
Answer: Open systems are energy that can be transferred between the system and its surroundings. Close systems are systems that do not transferred to its surroundings. Isolated systems is a thermodynamic system which cannot exchange either energy or matter from outside its boundaries of the system.

Which process involves a decrease in the dispersal of matter? Select the correct answer below: heat exchange between two solids
Answer:
The options are
A.heat exchange between two solids
B.the decomposition of a compound into its constituent elements
C.the precipitation of a solid
D.none of the above
The answer is
C.the precipitation of a solid
Dispersal of matter involves the process whereby there is more space occupied by the resulting element/compound than the initial one. For example the conversion of liquid to gas means that it has an increase in the dispersal of matter as the gas particles will contain more space when compared to a liquid.
Precipitation of a solid means conversion of a liquid to a solid. A liquid is known to contain more space which means there is a decrease in the dispersal of matter.
The process that involved the reduction in the dispersal of matter should be the precipitation of a solid
What is the dispersal of matter?It refers to the process in which it contains the additional space that should be occupied. Like the conversion of the liquid to gas represent there should be increment in the disperson of the matter since the particles of the gas comprise more space at the time when the comparison is to be done with the liquid. Here, precipitation of the solid represent the transformation of the liquid to the solid.

When brown iodine is exposed to starch it turns dark purple. In an experiment, you placed a cornstarch solution in a small plastic bag. Next, you placed the bag in a beaker of water containing 10 drops of iodine. If the solution in the plastic bag turned dark purple (Select all that apply)
a) the plastic bag was permeable to cornstarch.
b) the plastic bag was permeable to iodine.
c) the iodine moved into the plastic bag.
d) the cornstarch moved into the beaker.
e) the plastic bag was selectively permeable.
Answer:
b) the plastic bag was permeable to iodine
the plastic bag was selectively permeable
the iodine moved into the plastic bag.
the plastic bag was permeable to cornstarch.
Explanation:
The experimental set up represented the concept of osmosis.That is the movement of water molecules from the region of higher water potential to region of lower water potential through a semipermeable membrane(a cell membrane which only allows water and certain molecules to pass through,but restrain other molecules through its pores.
Generally potassium iodine test is the standard test for starch.
Therefore, in the question,water moves iodine molecules as iodine solution(from high water potential) to move across the paper bag(semi permeable membrane) to the reach the corn solution.(low water potential,high solute potential).This turns the starch in the corn solution blue-black/purple.
If the solution in the plastic bag turned dark purple:
the plastic bag was permeable to iodine. That is option (B)the iodine moved into the plastic bag. That is option (C)the plastic bag was selectively permeable. That is option (E)To test for the presence of starch in a solution, iodine solution is used. This gives a blue-black coloration which occurred due to the formation of a starch-iodine complex.
From the above experiment, the plastic bag which contains the corn starch solution, separates the solution from water containing 10 drops of iodine.
The turning of the solution, inside the plastic bag, into blue black signifies the formation of starch-iodine complex between the cornstarch solution the iodine water.
The reaction was able to occur because the plastic bag, which is selectively permeable to iodine, allowed the movement of iodine from the beaker of water into it. This is called diffusion.
Therefore, if the solution in the plastic bag turned dark purple it means that the plastic bag which is semi permeable allowed the movement of iodine into it.

Vaccination is a process of injecting a dead or weakened form of a pathogen into the body. How does this help strengthen the immune system? It allows the body to increase its internal temperature. It allows the body to regulate the inflammatory response. It allows the body to keep pathogen information for future infections. It allows the body to increase its desire to eat healthy food.
Answer:
It allows the body to keep pathogen information for future infections.
Explanation:
Vaccination is the process whereby a substance called VACCINE is injected into body in order to prepare the immune system for resistance against infections. A vaccine contains the harmless or dead version of a pathogen called ANTIGEN, which functions to give the immune system defense mechanism against that form of pathogen in future.
The vaccine works by stimulating the immune system of the body to fight against the antigens in the same way it will fight against an actual pathogen in the future. Hence, the body keeps the information on how to combat such pathogens when there is an actual infection.

List three protozoan infections of the circulatory system that are transmitted by arthropods. Include the disease name, specific organism (genus species), vector that is the intermediate between hosts, and disease progress in humans.
Answer:
List three protozoan infections of the circulatory system that are transmitted by arthropods:
Malaria
Toxoplasmosis
Chagas disease (American trypanosomiasis)
Explanation:
Malaria is a prozotoan infection, that can be produced by several protozoan, in the genus Plasmodium. This Plasmodium infect red blood cells and the vector that trasmites it is the Anopheles mosquitoe. In this disease, red blood cells can have severe damage in different organs because of the hemolysis.
Toxoplasmosis is a disease caused by the protozoan Toxoplasma gondii. The main vector of them are domestic cats. When cats are infected, T. gondii oocysts is found in their feces and it can spread to humans. This disease is generally asymptomatic, except when the patient has AIDS or in pregnancy, which can be very dangerous and fatal.
Chagas disease, or American trypanosomiasis is caused by protozoan Trypanosoma cruzi and is generally transmitted to people thanks to the feces of triatomine bugs. Some of the acute symptoms include fever, vomiting, headache, and in severe cases people can develop a chronic disease. In the worst cases it can produce flaccid cardiomegaly (enlargement of the heart) leading to heart failure and death.
The force of a muscle contraction is higher when the muscle is stimulated every 0.5 secs than when stimulated with the same voltage every 0.05 seconds.
a. True
b. False
Answer:
b. False
Explanation:
Increasing the frequency of muscle stimulation causes wave summation to occur, which causes an overlap of muscle twitch. When this muscle summation happens, the force generated in the muscle increases. This means that stimulating the muscle every 0.5 seconds will generate less muscle contraction force than when stimulated every 0.05 seconds
Biochemical and genetic experiments have demonstrated that the _________ of tRNA are important for recognition by its cognate aminotransferase-tRNA synthetase.
Answer: Acceptor stem and anticodon loop.
Explanation:
Transfer RNA (tRNA) is a small RNA nucleic acid involved in protein synthesis (translation). Each tRNA molecule has two important areas:
A region of trinucleotides, called the anticodon A region where a specific amino acid binds.During translation, the ribosome reads the sequence of the mRNA in groups of three bases to assemble the protein. So, in the mRNA chain there are codons, set of three bases, which determine the amino acid to be added to the peptide chain. The tRNA transfers the amino acid to the ribosomes, and then arranges them along the messenger RNA (mRNA) molecule. Then, the tRNA must have an anticodon that is complementary to the codon. Each type of tRNA is specifically combined with 1 of the 20 amino acids to be incorporated into proteins.
This means, during translation, each time an amino acid is added to the growing chain, a tRNA molecule is formed whose base pairs have a complementary sequence with mRNA molecule, ensuring that the appropriate amino acid is inserted into the protein. So, tRNA is a key link between RNA transcription and the translation of that RNA into protein. On the other hand, aminotransferases are enzymes responsible for attaching amino acids to the 3ʹ‐end of cognate tRNAs.
The acceptor stem is the site of attachment of amino acids to tRNA, and anticodon loop is the site of tRNA that is complementary to the codons found in mRNA (that determine the amino acid that will be added) This means, both parts are important for recognition, because the acceptor stem is where the amino acid is, and the anticodon loop ensures that the appropriate amino acid is inserted into the protein.
Membrane-bounded vesicles that contain enzymes for oxidizing small organic molecules with the formation of hydrogen peroxide are Group of answer choices
Answer:
peroxisomes
Explanation:
The peroxisomes represent one of the organelles of the cell. They are usually small and characterized by membrane-bound vesicles that contain oxidative enzymes.
The enzymes in peroxisomes are involved in the oxidation of organic molecules - a process that leads to the formation of hydrogen peroxide. The later is further converted to water and oxygen by the constituent catalase enzyme of the peroxisomes. Fatty acids are also oxidized in peroxisomes but instead of hydrogen peroxide, acetyl groups that are utilized in other biosynthetic reactions are produced.
