Compare and contrast human respiration and cellular respiration.
Breathing involves inhale of oxygen from the atmosphere into the lungs and exhale of carbon dioxide from the lungs into the atmosphere ; whereas cellular respiration involves breakdown of glucose into carbon dioxide and water in living cells, releasing energy.
During breathing, termed as external respiration, air from the atmosphere enters into the lungs. Exchange of oxygen and carbon dioxide occurs between the blood present in the capillaries and the air entering the lungs.
The R.B.C. in the blood present in capillaries pick up oxygen from the air entering the lungs and the hemoglobin molecule is converted into oxy-hemoglobin. Carbon dioxide from the deoxygenated blood is released into the air. The air carrying carbon dioxide is exhaled out of the lungs.
Thus breathing involves intake of oxygen from the atmosphere into the lungs and exit of carbon dioxide from the lungs into the atmosphere.
Cellular respiration, also termed as internal respiration, occurs in living cells. The oxygenated blood is carried to all living cells in the body of an organism through blood circulatory.
Cellular respiration involves breakdown of glucose into carbon dioxide and water in presence of oxygen, releasing energy. Oxygen carried by blood is used in cellular respiration and carbon dioxide released combines with hemoglobin in RBCs.

Human Respiration involves oxygen and carbon dioxide exchange, while cellular respiration is about cells producing energy through glucose. The processes differ in scale and purpose.
Human Respiration involves the exchange of oxygen and carbon dioxide, while cellular respiration is the process where cells generate energy by reacting oxygen with glucose. The main difference lies in the levels at which these processes occur.
In respiration, oxygen is inhaled to supply the body with oxygen and expel carbon dioxide, whereas in cellular respiration, cells break down glucose to produce ATP, water, and carbon dioxide.
The human body maintains a temperature of around 98.6 degrees at all times. Enzymes are involved in almost every chemical reaction in the body. Which of the following describes the connection between these two statements? A. Enzymes function best at a specific temperature.B. The body needs to be warm to prevent hypothermia.C. The body is kept relatively warm to prevent too much enzyme action. D. There is no connection between the two statements.
Answer:
A. Enzymes function best at a specific temperature.
Explanation:
One of the factors that determinate the enzyme activity is temperature. Each enzyme has a temperature optimum (the temperature at which its activity is the highest) and it corresponds to the normal body temperature for humans (around 98.6 degrees Fahrenheit or 37 degrees Celsius). Some of them can work on lower temperatures while some of them can increase their activity with the increase in temperature. But, since enzymes are usually proteins, high temperature (above 40 degrees Celsius) might denature them and consequently enzymes lose their activity.

In a relatively small iguana population the allelic frequency is tracked for three generations. Webbing is a recessive allele; no webbing is the dominant allele. During one very rainy spring and summer, a flood washes all the iguana without webbed feet out to sea. By the fall, and three generations later, you have the gene pool seen here. This is an example of A) gene flow. B) immigration. C) genetic drift. D) founder effect.
Answer:
The answer is C
Explanation: The random change in the gene pool is due to genetic drift. Remember, genetic drift occurs at a more rapid rate when the population size is reduced. The flood is a random occurrence. It could have as easily been a drought.
Answer:
C) genetic drift.
Explanation:
In this question, the alleles of the dominant trait that is without webbed feet are eliminated from the population due to flood in the area where the iguana population was living.
This elimination of the dominant alleles due to flood is a by chance event or a random event. This event changed the gene pool of the population and the population with left or recessive alleles will survive.
This change in the gene pool of a small population due to the random effect is known as the genetic drift.
Thus, Option-C is the correct answer.

Why are skeletal muscle fibers multinucleated
Answer:
It is because large skeletal muscle fibers form by the fusion of thousands of individual muscle cells
Explanation:
During the developments of muscle fibers, multinucleated arrangment is formed and it is also known as syncytium (syncytium is defined as multiple cell fusions of uninuclear cells).
Multinucleated arrangment of muscle fibers makes the muscles efficient, because many nuclei can control the contractions of long cell better.
Skeletal muscle fibers are multinucleated due to their development from multiple smaller cells known as myoblasts, each with its nucleus. The multiple nuclei allow for increased production of proteins and enzymes, enabling quick recovery from damage, and the ability to adapt to physical exercise.
Explanation:Skeletal muscle fibers are referred to as multinucleated because they contain many nuclei. This unique characteristic is a result of their development process, in which numerous smaller cells, known as myoblasts, fuse to form a mature muscle fiber. Each myoblast has its nucleus and when they fuse, their nuclei are retained in the final muscle fiber. This generates mature muscle cells with multiple nuclei dispersed within them.
Unlike cardiac and smooth muscle cells, skeletal muscle fibers are long and cylindrical. They can be quite large, with diameters up to 100 μm and lengths up to 30 cm. These unique cells functionally contract through signaling from the nervous system and perform a significant role in various body movements and functions.
The presence of multiple nuclei in skeletal muscle fibers provides multiple copies of genes, enabling the production of large amounts of proteins and enzymes essential for muscle contraction and relaxation. This property equips skeletal muscles with the ability to recover quickly from damage and adapt to physical exercise by synthesizing more protein in response. Therefore, the multinucleated nature of skeletal muscle is essential to their function and adaptability in the human body.

Which of the following would be an example of an organism creating a positive feedback interaction with its environment?Tamarisk shrubs are highly salt-tolerant; they take up salty water, but have special glands that secrete excess salt onto their waxy leaf surfaces, thus storing it out of the way where it can’t harm their cells. When the foliage falls, the salts wash into the soil, increasing the soil salinity. Over time, the salinity increases to a level that is toxic to almost any plant other than the tamarisks, which allows their offspring to grow where other plants have died.Unlike most organisms, nitrogen-fixing bacteria can grow well in soils with very low levels of available nitrogen, because they can convert N2 into a biologically-available form, which they can use to support their own growth. As numbers of N-fixing bacteria increase, more nitrogen becomes available in the soil, in part because some usable nitrogen “leaks” into the environment, and in part because the cells eventually die, releasing all of their usable nitrogen into the soil. As the levels of usable nitrogen increase, other organisms can grow near the N-fixing bacteria, competing with them for other resources, like carbon and water.
Answer:
Tamarisk shrubs
Explanation:
Positive feedback is a system in which component A produces more of component B which increases the production of A. In the example above, Tamarisk shrubs increase the soil salinity, which increase the growth and reproduction of more Tamarisk shrubs. So, Tamarisk shrubs is component A, environmental salinity is component B.

Sexual reproduction involves the joining of two sex cells to form a new organism. Describe how when the sexual reproduction occurs genetic material from both parents is passed on and combined to form the genetic code for the new organism.
Sexual reproduction involves two parents producing offspring that are genetically unique in that two haploid gametes join in the process of fertilization to produce a diploid zygote.
What is Sexual reproduction?Sexual reproduction is defined as the type of reproduction that involves a complex life cycle in which a gamete with one set of chromosomes fuses with another gamete to form a zygote that develops into an organism that has the same set of chromosomes.
Zygote develops into a new individual whereas sexual reproduction is explained as the major form of reproduction in living beings. Sexual reproduction has the advantage over asexual reproduction as it increases the genetic variation which expands the gene pool.

Final answer:
Sexual reproduction involves the combination of genetic material from two parents through the processes of meiosis and fertilization, resulting in a genetically unique offspring. Gametes merge to form a diploid zygote, which develops into a new individual with a genetic code derived from both parents. This process introduces genetic diversity, crucial for species adaptation and evolution.
Explanation:
Sexual reproduction involves two parents contributing their genetic material to produce a genetically unique offspring. This process starts with the production of gametes, which are haploid cells meaning they carry half the number of chromosomes typical for the species. Gametes are formed through a special type of cell division called meiosis, ensuring diversity and a reduced chromosome number.
When gametes from two individuals unite during fertilization, they form a zygote. This zygote is a diploid cell, which means it contains a complete set of chromosomes - half from each parent. The genetic material from both parents is thus combined, forming the genetic code for the new organism. This combination introduces genetic diversity, which is crucial for adaptation and evolution. The zygote will then undergo multiple rounds of cell division and develop into a new individual through a process guided by this genetic code.
The success of sexual reproduction largely depends on this blending of genetic material, which provides a mechanism for increased variation within a species. This variation is essential for the survival and adaptation of species in changing environments.
As a ribosome translocates along an mRNA molecule by one codon, which of the following occurs? The tRNA that was in the A site moves into the P site. The tRNA that was in the P site moves into the A site. The tRNA that was in the P site moves to the E site and is released. The tRNA that was in the A site departs from the ribosome Both A and Care correct.
Answer:
The tRNA that was in the A site moves into the P Site, and the tRNA that was in the P site moves to the E site and is released.
In protein translation, tRNA moves through the A, P, and E sites of the ribosome, catalyzing peptide bond formation and translocating along mRNA. The ribosome proceeds to next codon after each tRNA moves from the A site to the P site, and then from the P site to the E site.
Explanation:During the elongation phase of protein translation, charged tRNAs move through the A, P, and E sites of the ribosome. This process allows the polypeptide chain to form and grow. Specifically, a charged tRNA first binds to the mRNA in the A site of the ribosome and a peptide bond is formed between two adjacent amino acids, catalyzed by an RNA-based enzyme, peptidyl transferase. Subsequently, the ribosome moves one codon along the mRNA, causing the tRNA that was in the A site to move into the P site.
Next, the tRNA that was in the P site moves to the E site, and it is released from the ribosomal complex. This sequence of tRNA movements-- from the A site to the P site, and then from the P site to the E site-- occurs with each translocation event, that is, each single-codon 'step' of the ribosome. Amazingly, the E. coli translation apparatus takes only 0.05 seconds to add each amino acid, meaning that a 200 amino acid protein can translate in just 10 seconds.
