If you pressed a stethoscope diaphragm firmly on a volunteer's skin at the following locations on the right side of the body: Inferior to the clavicle (this is the 1st intercostal space) In a more inferior intercostal space Along the medial border of the scapula What type of sounds are you listening for
Answer:
The correct answer is - Vesicular Breath Sound.
Explanation:
The vesicular breathing is lower-pitched and soft where expiration is shorter than inspiration and there is no pause between expiration and inspiration. It can be heard through the thorax and with a stethoscope around the lungs or the thorax inferior to the clavicle, medial border of the scapula, and intercostal space. It can be heard with each expiration around the lung area.
Thus, The correct answer is - Vesicular Breath Sound.

1. A cladogram is an evolutionary tree that diagrams the ancestral relationships amongst organisms.
The similarly alongside the cladogram you move,the greater variations in DNA the organisms have compared to the common ancestor.Final answer: The correct option is B,A,C,humans.
2. DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorilla’s DNA sequence.
Final answer: The correct option is (c).
3. These structures are known as homologies because they result from species evolving from the same common ancestor.
Explanation for correct option:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor.Explanation for incorrect option:
Analogies structure are body parts that have a similar function but differ in structure.Final answer: homologies; from the same common ancestor.
5. All vertebrate embryos have a tail and gill slits at some point during embryonic development.
Vertebrates are similar in origin and that they develop similarly, implying that they are related, have common ancestors.Final answer: These species share a common ancestor.
5. Fossil B was found deeper in the ground than Fossil A.
Fossil A could not be older than Fossil B as it has settled for a shorter period of time, and is higher up to the surface.If the two species existed at the same time, they could be at same heights in the soil.Final answer: Fossil B is most likely older than Fossil A.
6.This shows that the vertebrates are similar in origin and that they develop similarly, implying that they have common ancestors.
In the embryonic stages, they all possess the ventral heart, aortic arches, gills and gill slits which are exactly like those of the fish embryo. Presence of tail at some stage of development. These observations support the idea of organic evolution.This similarity of basic plan is because of shared genetic material and those genes that are still the same among organisms.Final answer: All vertebrates develop a backbone that protects the spinal cord.
7. Mutations have no effect on the organism because they are repaired before protein synthesis occurs.
Silent mutations lead to a change of one of the letters in the triplet code that represents a codon, but despite the single base change, the amino acid that is coded for remains unchanged or similar in biochemical properties.Final answer: The mutated sequence still codes for the same amino acid.
8. Embryological develoment is typically studied when analyzing not-yet-born (or unhatched) animals.
Explanation for correct answer:
Embryology is a branch of science that is related to the formation, growth, and development of embryo.Explanation for incorrect answer:
The theory of evolution is based on the idea that all species are related and changes over time.DNA sequencing refers to the technique for determining the exact sequence of nucleotides, or bases, in a DNA molecule.Final answer: Embryological development.
9. DNA molecules can scientists analyze to get a better understanding of how plants and animals evolved from a common ancestor.
Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related.Final answer: DNA molecules.
10. Embryology is important to understanding a species' evolution, since some homologous structures can be seen only in embryo development.
Embryos of organisms that have a closer genetic relationship to one another tend to look similar for a longer period of time since they share a more recent common ancestor.Final answer: Embryos go through various stages that suggest the animal’s evolutionary process.
11. A DNA analysis can help determine is the species is related to any other organism like on earth.
After isolating the DNA from its cells, specific regions are copied with a technique known as the polymerase chain reaction, or PCR. PCR produces millions of copies for each DNA segment of interest and thus permits very minute amounts of DNA to be examined.12. Evolution is a process of gradual change that takes place over many generations.
Evolutionary biology allows us to determine not only how and why organisms have become the way they are, but also what processes are currently acting to modify or change them.It helps us to understand the development of antibiotic resistance in bacteria and other parasitic organisms.13. The first alligator ancestors developed approx. 245 million years ago.
The main reason for the change in the body structure of alligator is due to change in environmental condition.DNA shows how related species are to other species.Fossils can be used to prove the existence of the evolution of alligators and to compare and contrast what they looked like in the past to what they look like now.you can learn more about evolution here:

How do vaccinations provide protection against pathogens?
O Antibodies manufactured in a lab are injected into the patient. This
causes the release of antigens that will provide protection against
specific organisms.
O Shots containing antibodies are injected into the circulatory system.
These antibodies are transported to the cells where they are
needed.
O A dead or changed virus or bacteria is injected into the body. This
tricks the body into producing pathogen-specific antibodies for
future protection.
White blood cells are artificially produced in a lab and made into a
vaccine. This is then injected into the body to provide protection
against all organisms.

Plants contain the carbohydrates starch and cellulose. in the spring when stem growth is at its fastest rate, cellulose production rates are
increased in some plants. In the months with less sunlight, the level of starch decreases in some plants. What does this information
demonstrate?
Answer:
The correct answer is - Two functions of carbohydrates are structural support and energy storage.
Explanation:
In plants there are normally two carbohydrates are produced are starch and cellulose that have similar molecular structures but their biological function is drastically different.
Cellulose is used as a structural unit of the plant cell wall, its production rates increase during the growth of the plant during spring. starch is a carbohydrate that stores energy reserve that builds up during a sunny time and is consumed during wintery or less sunny days.

“Scientist have long understood how nutrients move from the oceans surface to its depths. As phytoplankton die, they sink and collect on the ocean floor. But if nutrients are continually sinking to the depths of the ocean, how are surface waters replenished with nutrients? Scientist discovered that in certain regions of the ocean, the nutrients-rich deep water was upwelling, or rising to the surface”
which phrase from the paragraph helps you to understand that ocean health involves steady restoration
Answer:
"As phytoplankton die,they sink and collect on the ocean floor"......."scientist discover that in certain regions of the ocean the nutrients deep water was rising to the surface"
Explanation:
this shows steady restoration of ocean nutrients
As seen that the death of planktons lead to uprise in oceanic nutrients .the cycle just keeps going on and on
its quite self explanatory
