Answer:
The Isopropanol had a lower heat of vaporization than that of water, meaning that it didn't have to have as much energy to accomplish a phase change, in this case evaporation.
According to the forces of attraction, isopropanol has lower heat of vaporization as compared to water .
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

What is the difference between natural selection and selective breeding? Then, give examples of natural selection and selective breeding?
Natural Selection is when traits are "naturally" selected for, because "survival of the fitttest." Example would be a species becoming bigger over time, because the smaller animals of that species were more likely to be eaten by predators. Natural selection is when the "best" trats are passed down due to chance
Selective breeding is if an outside forece (like a dog breeder) "chooses" a triat to be passed down. Example, instead of breeding a brown dog with a white dog, the breeder breeds two black dogs together in orer for the litter to all have black fur

1) You are studying the uptake of a certain molecule into cells that produce no ATP. You discovered
that it in fact does become transported into the cell. To further your research, your colleague
decides to do the same experiment but supplies the cell with ATP. He discovers that the cell
transports more of the molecule intracellularly.
a. Describe the difference in transport between your experiment and his. Explain. (10pts)
b. What characteristics must this molecule have in order to use both types of transport?
(10pts)
Answer:
Your cell use passive transport whereas your colleague cell use active transport.
Explanation:
There is a great difference in the type of transport between your experiment and his because you provide no ATP to the cell for transport means you use passive transport in which the cell moves molecules without the use of energy while on the other hand, your colleague provides ATP to the cell means the cell transports molecules with the use of energy so the cell use active transport. The characteristics of molecules have the presence of both type of cells which do both type of transport.
Larvae of the Diamondback moth feed on cauliflower paleo Aunt Farmers commonly used pesticides to repel them all from the cauliflower plants the larvae of the Diamondback moth arnab resistant various types of pesticides which statement best describes how the larvae became resistant?
Answer:
Mutation.
Explanation:
Mutation is the factor that is responsible for the acquiring resistance of various pests against pesticides because in mutation the genetic makeup of the organism changes which has no effect of the chemicals applied on them. Repeated use of the same type of pesticides to control a specific pest can cause changes in the genetic makeup of a pest that leads to another form of pest which causes pesticide resistance in the new type of pest so we can say that mutation is the main cause of resistance in pests.

A container holds an element and a compound that are not chemically combined. Is this an element, a mixture or a compound?
Answer:
Mixture.
Explanation:
Mixture can be defined as a combination of two or more substances which are present in varied proportion and can be visibly seen by with our naked eyes.
In Science, there are two (2) main types of mixture and these are;
I. A homogeneous mixture: it can be defined as any liquid, solid or gaseous mixture which has an identical or uniform composition and properties throughout any given sample of the mixture. In Chemistry, all solutions are considered to be a homogeneous mixture. For example, aqueous hydrogen chloride is a homogeneous mixture of water and hydrogen chloride.
This ultimately implies that, in a homogeneous mixture, the different parts are uniformly (evenly) distributed.
II. A heterogenous mixture: it can be defined as any mixture which has a different or non-uniform composition and properties throughout any given sample of the mixture. This ultimately implies that, the constituents of a heterogenous mixture always remain separate in the sample and as such comprises of two or more phases.
For example, a mixture of sand and coffee is simply a heterogenous mixture and can easily be separated into their various components.
In this scenario, a container holds an element and a compound that are not chemically combined. Thus, this is a mixture.

Read this Pulmonology Consult excerpt:On physical exam, the patient is alert. He takes occasional pauses when he says long sentences, but otherwise, he is not in any distress. He has an occasional cough during his exam. His skin is pink and dry, and his lips are moist. His heartbeat is regular in rate and rhythm, without a murmur. On lung examination, he has whispered pectoriloquy on the right side with decreased breath sounds. He does not have any retractions or nasal flaring noted. His liver and spleen are not large.According to the excerpt, what was found upon lung examination on the right side?A. "Whispered pectoriloquy" - a chest that protrudes like the keel of a ship when the patient whispersB. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is presentC. "Retractions" - reverberations in the chest when it is struckD. "Retractions" - a dull sound in the chest when it is struckE. "Whispered pectoriloquy" - a chest that is hollowed out when the patient whispers
Answer:
B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present
Explanation:
Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.
Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.
Whispered pectoriloquy is used to detect vocal resonance. It is used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.
3.When Watson and Crick built and proposed the DNA structure, they determined three important features.
What were the three features they proposed? Select all that apply.
Multiple select question.
A) Two outside strands consist of alternating deoxyribose and phosphate.
B) Two outside strands consist of alternating ribose and phosphate.
C) Guanine and cytosine bases pair to each other by two hydrogen bonds.
D) Guanine and cytosine bases pair to each other by three hydrogen bonds.
E) Guanine and adenine bases pair to each other by three hydrogen bonds.
F) Cytosine and thymine bases pair to each other by two hydrogen bonds.
G) Adenine and thymine bases pair to each other by three hydrogen bonds.
H) Adenine and thymine bases pair to each other by two hydrogen bonds.
According to Watson and Crick, DNA replication used each strand's nucleotides as a template for new strands. Thus,option A, D, H is correct.
What is the Watson and Crick model about DNA?Watson-Crick DNA structure. The molecule of DNA is a double-stranded, helical structure. It consists of two sugar-phosphate backbones on the outside and nitrogenous base pairs on the inside, bound together by hydrogen bonds.
DNA behaves like a double helix made up of two protracted, intertwined helical strands.
In their model, the bases along one DNA strand matched the bases along the other DNA strand. Each DNA strand comprised discrete units known as bases.
Therefore, Watson and Crick built and proposed the DNA structure, which determined important features of DNA.

In bunnies long ears are dominant over short ears. If two heterozygous bunnies are crossed, what is the probability their offspring will have the long ear phenotype? 1. 25% 2. 50% 3. 75% 4. 100%
Answer: 75%
Explanation:
See my picture for my work. Use a punnett square.
Answer: 75%
Explanation:
Heterozygous means that one allele would be dominant, and the other would be recessive. I will use B for the dominant allele, and b for the recessive allele.
Next, create a Punnett square (look at the pic).
To make the Punnett square, draw a 2 × 2 table. Put Bb on the top (one over each column) and Bb on the left side (one next to each row). Cross multiply. Remember to always put the dominant allele (in this case, B) in front of the recessive allele (in this case, b). The dominant allele will always be exhibited in the organism. So, the answer is 75%, since 3/4 of the different combinations of alleles is long ears.
