Classical conditioning takes place when a(n) ________ is continuously matched with a(n) ________.
Classical conditioning takes place when a CONDITIONED STIMULUS is continuously matched with an UNCONDITIONED STIMULUS.
It is a process of learning by combining two stimulus, one which has a neutral effect and the one which can produce a biological result. It was studied on dogs by Ivan Pavlov.
Neutral stimulus is the conditioned stimulus and the biological is the unconditioned one.

Some individuals have a mutated recessive allele and a homozygous individual is resistant to HIV infection and AIDS. Some populations have a high frequency of the mutant allele. What inference can be made about the mutant allele? (1 point)
Heterozygous individuals must be genetically advantaged even if they are not resistant to HIV.
The mutated allele must have developed and been acquired by many people before exposure to the virus.
The mutated allele must not be inherited by offspring or the disease would be close to eradication.
Being homozygous is an advantage for the mutated allele, while being heterozygous is a genetic disadvantage.

An area recently became prone to deforestation. Now there are few trees left in the vicinity. How would this change affect the cycles of Earth?
this dude....
C makes sense, but it may be wrong... apparently transpiration is how plant's make ground water evaporate and generate clouds... most common in rain forests. It seems counter intuitive, but without it the ground simply dries out due to regular evaporation and the sun...which would sap all of the moisture out of the ground.

A scientific paper that has passed through the peer review process is more respected than one that has not. Why might a scientist value a peer-reviewed paper?
A. The analysis of the experimental results is guaranteed to be entertaining.
B. The described experiment meets or exceeds the standards of good science.
C. The scientist who wrote the paper is likely to become a famous person.
D. The described materials are expected to become a good investment.
The correct answer is B. The described experiment meets or exceeds the standards of good science.
Explanation:
In science, it is common after research scientists publish information about the process and results in scientific papers or articles. Additionally, the credibility and reliability of this documents and of the research itself depend on multiple factors and one of this is whether the paper has been review by another expert in the field which called peer-reviewed paper. Indeed papers that have gone through the peer-review process are more credible and therefore more value by other scientists as in general terms this guarantees the results can be believed as each step in the research fits with the standards of good science because the scientists who reviewed the paper approve it. Therefore, the reason a scientist value a peer-reviewed paper is that the escribed experiment meets or exceeds the standards of good science.

A horse does 860 J of work in 420 seconds while pulling a wagon. What is the power output of the horse? Round your answer to the nearest whole number.
The power output of the horse is
W.
Answer:
Power output, P = 2 watts
Explanation:
It is given that,
Work done by a horse, W = 860 J
Time taken, t = 420 seconds
We need to find the power output of the horse. Power output is given by work done divided by total time taken i.e.
[tex]P=\dfrac{W}{t}[/tex]
[tex]P=\dfrac{860\ J}{420\ s}[/tex]
P = 2.04 watts
or
P = 2 watts
So, the power output of the horse is 2 watts. Hence, this is the required solution.

What are the steps (in the correct order) that link a change in the base sequence of a gene to a change in the phenotype of an organism like a mouse or a human? see section 16.2 (page 339) ?
The answer is DNA to RNA to protein. The change in DNA sequence will be reflected (through complementary base pairing) on the formed Messenger RNA during transcription. Subsequently, during translation of the mRNA to protein (by ribosomes), the amino acid sequence will change due to changes in the codons. Proteins, as you may know, are what determines the phenotype of organisms while DNA determines the genotype of the same organism.

The method by which lymph is pushed through the lymph vessels is via
Lymph is moved through lymph vessels by skeletal muscle contractions, varying external pressures, and one-way valves that prevent backflow, as the lymphatic system lacks a central pump like the heart.
The method by which lymph is pushed through the lymph vessels is via a combination of movements caused by skeletal muscle contractions, external pressures, and the one-way valves present in the lymphatic system. Blood pressure at the capillaries initially forces plasma into the lymph spaces, where it becomes lymph and exerts pressure on the walls of the lymph vessels. This lymph then moves through the network of lymphatic vessels primarily due to the contraction of skeletal muscles around these vessels as the body moves, and the one-way valves that prevent backflow of lymph, ensuring it flows in the correct direction towards the heart.
Lymphatic capillaries absorb this fluid from the tissues and transport it through larger lymphatic vessels to eventually reach the two large lymphatic ducts in the upper chest. From there, lymph enters the circulatory system by flowing into the subclavian veins. The lymphatic circulatory system does not have a central pump like the heart in the cardiovascular system, hence the reliance on muscle contractions and movement to propel lymph through the body.

Explanation:
Because the dna cannot leave the nucleus to get to the ribosomes, the genes for proteins must be transcribed into ______________ that can leave the nucleus.
The DNA in cells is transcribed into messenger RNA (mRNA), which leaves the nucleus and delivers the genetic code for specific proteins to the cytoplasm for protein synthesis. This process, called transcription, allows for proteins to be efficiently and properly synthesized in the cell.
Explanation:The DNA in cells cannot leave the nucleus to get to the ribosomes directly. Instead, the genes for proteins are transcribed into messenger RNA (mRNA) that can leave the nucleus. This mRNA is a single-stranded nucleic acid that delivers a copy of the specific gene's genetic code from the nucleus to the cytoplasm, where it interacts with ribosomes and other cellular equipment to manage protein synthesis.
During the process of transcription within the cell nucleus, mRNA molecules are produced, which are then modified and sent into the cytoplasm for translation. The transcript is decoded into a protein with the help of a ribosome and tRNA molecules. This system allows for the necessary proteins to be synthesized properly and at the right time, without having to expose the actual DNA.
