Write a program that simulates the growth of parasite population in an animal over time. Each parasite organism reproduces itself at some time interval. Animals may undergo drug treatment to inhibit the reproduction process, and clear the parasites from their body. However, some of the parasite are resistant to drugs and may survive.
Answers
Answer:
Good environmental conditions and food availability.
Explanation:
Good environmental conditions and food availability are the factors that simulates the growth of parasite population in an animal with the passage of time. Yes, drug can reduces the population of parasites but all parasites can't be removed because some gain resistance against that chemical which allows them to survive in that environment so good environmental conditions and food availability increases population of parasite.

In a diploid plant species, the proportion of progeny expected to be tall and produce round fruit is 32%.
In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. The expected percentages of progeny phenotypes are tall oval = 41%, short round = 41%, tall round = 9%, and short oval = 9%.To determine the proportion of progeny expected to be tall and produce round fruit, we need to consider the alleles for each trait. Allele D produces tall plants (dominant) and allele d produces short plants (recessive). Allele R produces round fruit (dominant) and allele r produces oval fruit (recessive).From the given percentages, we can deduce that tall ovals and short ovals combined make up 9%. Since tall oval is 41% and short oval is 9%, the proportion of progeny expected to be tall and produce round fruit is 41% - 9% = 32%.Therefore, the proportion of progeny expected to be tall and produce round fruit is 32%.For more questions on diploid plant

As part of your undergraduate research project, you are characterizing three polypeptides of approximately equal molecular weight from human plasma. Using various physical techniques, you have established that in their native states one of the polypeptides is a monomeric, cigar-shaped molecule, the second is monomeric and approximately spherical, and the third is the subunit of a teiramer of identical subunits. Another student (Lisa, who you arc working with on the project) in the research group has determined the amino acid compositions of the three proteins. However, when Lisa brings you the data, shown in the table below, you are greatly upset to discover that she failed to note which composition corresponds to which protein. Another student. Alison, working in the lab (on another project) tells you that you should simply deduce which is which from the amino acid compositions themselves. Lisa is sure that Alison is wrong. Should you take Alison's advice? If you decide to do so, which composition would you assign to which protein, and why?
Answers
Answer:
You must not follow Alisson's advice.
Explanation:
The data analyzed by Lisa are shown in the figure attached below. When analyzing this data, you will see that it is not possible to deduce which protein is which efficiently, since the data is not enough to show the shape of the proteins.
To deduce which protein is which, from these data, would make the research imprecise, since there were no tangible justifications capable of justifying the deduction.
In a scientific research, all statements expressed must be scientifically justified and proven, in which case deductions cannot be part of the project.

Answers
Answer:
The cell membranes controls what goes in and out by having protein channels that perform their role accordingly sometimes like funnels and like a pump in different cases.
When a channel open in the plasma membrane it allows molecule to pass through, in this case there is no requirement for energy so it is a passive transport.
Gases and food particles broke down in water must be assimilated and waste or harmful substance and molecules must be remove. For most cells, this type of selective transport of all materials all through the cell must happen through the plasma membrane.

Explanation:
it's function is
The function of the middle ear is to transform sound waves into mechanical vibrations, which is the last option, as the middle ear is a part of the ear located between the outer ear and the inner ear. Hence, the correct answer is the last option.
The middle ear is a part of the ear located between the outer ear and the inner ear. Its main function is to transmit and amplify sound waves that enter the ear through the ear canal (from the outer ear) to the inner ear. The middle ear consists of three small bones called ossicles: the malleus (hammer), incus (anvil), and stapes (stirrup). These bones work together to transform the incoming sound waves into mechanical vibrations. When sound waves reach the eardrum (tympanic membrane) in the outer ear, they cause the eardrum to vibrate. These vibrations are then transmitted by the ossicles in the middle ear. Hence, the correct answer is the last option.

92ml 3.0 fl oz what is the ratio
Answers
The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).
1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).
Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).
Now we can express the ratio between 92 mL and 88.72 mL:
92 mL : 88.72 mL
Simplifying the ratio by dividing both sides by the greatest common divisor, we get:
46 : 44
So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

Mutations in the DNA change how proteins are made which leads to new and different forms of phenotypes.
Answers
A missense mutation is a Genetic alteration that causes the protein produced to encode a different amino acid at a specific location. Certain missense mutations change how the resulting protein functions.
Why do some changes in an organism's DNA sequence cause change, while others do not?While mutations always result in a change in the DNA sequence, they do not necessarily have a noticeable impact on the organism or alter the resulting protein. Since most amino acids can be encoded by two or more distinct codons, this is possible.
Can mutations be found using DNA sequencing?The ability to properly identify and characterise the majority of sequence changes makes direct DNA sequencing, in theory, the method for mutation identification with the highest degree of accuracy.

Explanation:
Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Answers
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.
