D. Explain the relationship between the pulse recorded in the finger and heart muscle contraction ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ E. Which components of the cardiac cycle (atrial systole and diastole, ventricular systole and diastole) are discernible in the pulse tracing? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Answer:
D. Heart contraction and pulse are connected with one another.
E. Atrial diastole and ventricle diastole.
Explanation:
Heart construction and pulse of an individual are connected as one can hear the pulse every time contraction of the heart is completed. Pulse can be understood by this that it represents the number of the contractions is completed by heart each time.
In the pulse tracing, there are two parts of the heart that are discernible which represents the contraction of the heart that are Atrial diastole and ventricle diastole.
The relationship between the pulse recorded in the finger and heart muscle contraction is that both are connected to each other. But, the analysis and processes are different from one another.
What is Muscle Contraction?
A process leading to shortening and/or development of tension in muscle tissues that means the thin filaments slide over the thick filaments and tension is generated between one another is called Muscle contraction.
The pulse recorded in the finger is a signal for flowing the blood throughout the body, while the process of heart muscle contraction signals for electrical conductivity. Both the functions are connected with each other and acquired by cardiac activities.
The components of the cardiac cycle that are discernible in the pulse tracing are Ventricular systole (contraction) and ventricular diastole (relaxation).
Therefore, both the pulse recorded in the finger and heart muscle contraction interconnected with one another and acquired by cardiac activity.

Jill has quite a menagerie of pets and she regularly has to deal with minor animal injuries. So when Johnnie, her rooster, spikes Jessie, her collie, on the muzzle with one of his long leg spurs, Jill knows what to do. She reaches for the hydrogen peroxide and thoroughly floods Jessie's puncture wound with the liquid. Jill observes, as always, that the hydrogen peroxide causes heavy fizzing at the site of the wound. She repeats the procedure several times a day over the next week, carefully inspecting the wound for signs of infection. The injury heals without complications and Jessie has a new respect for roosters.
a) What is hydrogen peroxide and how does it help to reduce the infection?
b) Why is hydrogen peroxide especially useful for treating puncture wounds?
c) What causes the fizzing associated with hydrogen peroxide use?
Answer:
a.) Hydrogen peroxide are highly reactive oxygen compounds used as an antiseptic
b.) Used in treating punctured wounds due to the nature of the wound which helps microorganisms to thrive.
c.) Fizzing associated with hydrogen peroxide use is due to presence of the enzyme catalase.
Explanation:
Hydrogen peroxide is a chemical compound which is made up of two hydrogen atoms and two oxygen atoms. It is powerful oxidizing agent which takes part in biological reactions. This is possible as it can remove electrons from other biological molecules which can damage other cellular components. It is used an an antiseptic to reduce infection because, being a powerful oxidizing agent, it has the ability to react with cell wall of these microorganisms through removal of electrons thereby causing damage to it.
Punctured wounds are narrow in structure which allows obligate anaerobic organisms to thrive because of reduced oxygen flow in the wound. Hydrogen peroxide can effectively eliminate these organisms which are most likely to cause infection in that site because they lack the enzyme called catalase.
Catalase is an enzyme which is present in living cells except obligate anaerobic organisms. It converts hydrogen peroxide into water and oxygen. The fizzing noticed by Jill while cleaning the wound with hydrogen peroxide is due to the catalase in Jill's own cells which converts the hydrogen peroxide to water and oxygen. When oxygen is given off, fizzing reactions are seen at the surface of the wound.

How do simple and complex sugars compare in their effect on your glycemic index?
Answer:
The glycemic index allows you to compare the ability of foods to increase blood sugar (glucose) levels. In general, simple carbohydrates have a medium to high glycemic index. In the case of complex carbohydrates, this varies.
Explanation:
The Glycemic Index (GI) is a measure that provides information on how quickly blood sugar levels rise after eating a certain food. Low glycemic index foods are those that have a low content of sugars or simple carbohydrates and that help regulate blood glucose levels, the consumption of foods with a low glycemic index has been proposed as a prevention and / or management factor of obesity, cardiovascular diseases, type 2 diabetes mellitus and some types of cancer. Complex carbohydrates are made up of larger, more complex molecules and are found primarily in the form of starch and fiber. Foods high in fat or fiber are digested more slowly, so they also cause a slower rise in blood sugar. A food with a high GI raises blood sugar faster than foods with a medium or low GI. The GI is higher when foods do not contain fiber and they are easily digested, since they reach the bloodstream quickly, it is also higher if there is sugar or if cooking destroys part of the fiber and favors the digestion of food.

Calcium ion can be combined with oxygen ion to form an ionic compound.
What is Ionic compound?A compound that is created through ionic bonding is known as an ionic compound. One atom transfers its electrons to another in a process known as electron transfer to form an ionic connection. Think about two pups.
The pups each have a bone. The puppies stand in for atoms. The bone is a metaphor for an electron. Both of the puppies are impartial. One dog snatches the bone from the other since it is a thief. Now that the bone is his, the puppy thief.
In order to create a puppy pair with the thieving puppy, which has a negative charge, the puppy without a bone, which has lost an electron and is now positively charged, will follow it about. The ionic compound is the puppy pair.
Therefore, Calcium ion can be combined with oxygen ion to form an ionic compound.

A small group of diploid triangular Sticky Notes were fluttering along the coast of The Mainland. A storm blew in and blew the Sticky Notes to an isolated island that had never previously been inhabited by Sticky Notes. After a few years, the Sticky Note population (though still small) has happily made the new island their home and are visited by an evolutionary biologist. The evolutionary biologist bands the Notes, collects tissue for a genetic analysis, and finds that this isolated population of Notes is not in Hardy-Weinberg equilibrium. Why is this, and what may be the potential long-term significance
Answer:
Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.
Explanation:
This is a special case of genetic drift: the founder effect.
The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.
The criteria for maintaining a Hardy-Weinberg equilibrium are:
Random matings No superposed generations No mutations No migration Infinite population size No natural selectionGenetic drift involved the un-accomplishment of random matings and infinite population sizes.
Genetic drift involves:
limited population sizes individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
You want to identify dominant /recessive relationship for skin color for a new frog species that you found in the rain forest. Assume that one autosomal gene controls skin color in this species. All of the frogs that you found for that spe- cies are bright blue or yellow. A bright blue female and bright blue male frog mate and produce all bright blue progeny. A yellow female and yellow male frog mate and produce a mix of bright blue and yellow progeny. Identify each trait (bright blue skin color and yellow skin color) as dominant or recessive. Explain your choices.
Required:
Identify the genotype for each parent in the two crosses.
Answer:
bright blue trait = recessive
yellow trait = dominant
Explanation:
let the letter B represent the gene for skin colour.
This means that the dominant gene is 'B' while the recessive gene is 'b'
A dominant gene is one that is exhibited phenotypically in the presence of both gene variants (heter0zygous state - Bb) while a recessive gene is only expressed phenotypically when it is in a h0m0zygous state (bb)
In order to find out the genotype of the parents, let us consider each cross one after the other.
1. A bright blue female and a bright blue male produce all blue progeny.
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny
From statement 2, it can be deduced that the trait for yellow colour is dominant because a cross of the parents exhibiting this trait produces bright blue offsprings too, meaning that the genetic composition of the parents contains the gene that codes for yellow colour. Since these parents show a yellow colour in a heterozygous state, then the trait for yellow colour is dominant.
Therefore, the genotypes of the parents in each case include:
1. A bright blue female and a bright blue male produce all blue progeny. (bb × bb)
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny (Bb × Bb)

As we discussed, plesiadapiforms were initially interpreted as being the first primates. They were then interpreted as being outside the direct primate lineage because they lacked many of the key traits that define the primate order. This debate continues today. Given what you know about the defining traits found in most living primates, describe four traits you think should be found in the earliest primates. What advantages would these traits have provided the first primates
Answer and Explanation:
Primates must have long, strong fingers capable of supporting their own body weight when they need to climb, the ability to climb trees and stereoscopic vision. These skills help primates not only to survive in the wild, but facilitate the obtaining of food, resistance to predators and reproduction, these characteristics being the most favorable to maintain the continuation of the active species and competitiveness among members of the species.
Differences in ocean salinity and temperature create...
...disturbances in the water cycle.
...different climates on land.
...masses of water that are different from each other.
...weather patterns with a lot of fresh water precipitation.
Answer:
Masses of water that are different from each other
Explanation:
salt water is denser than fresh water, so it makes sense that it would create masses of water that are different from each other, it won't affect the water cycle climate or weather cycle since the salt stays in salt water when it is evaporated, creating precipitation that is always fresh water.
