When compared to the leg muscles of an olympic sprinter, the muscles of an olympic marathoner would likely show a greater proportion of oxidative slow-twitch fibers?

Answers

This is a true statement.
The human body has two types of skeletal muscle fibers: slow-twitch and fast-twitch. Slow-twitch fibers are used for long-endurance actions, such as a marathon, while fast-twitch fibers are used for sudden bursts of movements such as a sprint. Therefore, an Olympic marathoner will have a greater proportion of oxidative slow-twitch fibers when compared to an Olympic sprinter.

Final answer:

The human population began growing at an unprecedented rate during the Industrial Revolution in the late 18th century, accelerating during the 20th century, primarily due to technological, agricultural, and medical advancements that improved living conditions and life expectancy.

Explanation:

The human population began to grow at a faster rate than at any other time in history around the start of the Industrial Revolution in the late 18th century. This marked the beginning of what is often called the population explosion. Advancements in technology, agriculture, and medicine have all contributed to exponential growth. The global population growth rate accelerated further during the 20th century and continues to grow in the 21st century. The shift from very slow growth to rapid increase can be visualized by the shape of a J-curve in population graphs.

For example, it took millennia for the human population to reach 1 billion around 1800 CE, and only a little over a century later, the population reached 2 billion. Within less than another century, an additional 5 billion were added, showcasing the exponential nature of recent population growth. Scientific advancements and industrialization played significant roles in creating conditions for the population to grow at previously unseen rates, which includes improved health care, increased food production, and better sanitation.

Answers

The fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of plasma protein. The glomerulus differs from other capillaries in the body in that it is drained by an efferent arteriole. Glomerulus and the Bowman's capsule constitute a renal corpuscle, the basic filtration unit of the kidney. The glomerular filtration rate is the rate at which blood is filtered through the glomeruli, and thus measures the renal overall renal function.
Final answer:

The fluid in the glomerular capsule is like plasma but lacks significant protein. The glomerulus distinguishes itself from other body capillaries in that an efferent arteriole drains it and maintains a higher blood pressure, facilitating efficient blood filtration.

Explanation:

The fluid in the glomerular capsule (also known as Bowman's capsule) is similar to plasma except that it does not contain a significant amount of proteins. This is because the filtration membrane separates the blood in the glomerular capillaries, and the capsular space allows small substances such as water, ions, and glucose to pass through but blocks larger ones like proteins and blood cells.

The glomerulus differs from other capillaries in the body in two main respects. Firstly, it is drained by an efferent arteriole, which is unique because, in general, capillaries merge into venules, not arterioles. Secondly, the glomerulus has a significantly higher blood pressure than other capillaries due to its position between two arterioles (afferent and efferent arterioles). This high pressure allows for the rapid and efficient filtration of blood.

Summarize the structure of DNA. Include information about the nitrogenous bases, sugars, and composition of the backbone. Which nitrogenous bases pair up together in DNA? RNA? Explain where covalent and hydrogen bonds are located. Also, fully explain the process of the central dogma (DNA, RNA, Proteins) in correlation of protein synthesis (DNA transcription and translation).

Answers

DNA backbone is made up of deoxyribose monomer sugars as the basic unit that are covalently connected in chains. Each deoxyribose sugar is a five (5)-carbon ring. The  5’ carbon covalently bonds with a phosphate while the 3’ carbon bonds to the next deoxyribose carbon ring. The 1’ carbon is covalently bonded to a nitrogenous base (either Adenine, Thymine, Cytosine, or Guanine ).


In DNA, Cytosine pairs with Guanine, and Adenine pairs with Thymine. In RNA, the same principle applies only that RNA has no Adenine base but Uracil. Therefore, Thymine pairs with Uracil while, similar to in DNA, Cytosine pairs with Guanine.


Covalent bonds occur in virtually all the bonds except between nitrogenous base pairs of opposite strands of DNA.


The central Dogma stipulates that DNA --à RNA--àProtein. During transcription, information on DNA is copied to messenger- RNA.  In eukaryotes messenger- RNA moves to the cytoplasm where it is then translated to protein by ribosomes.  In prokaryotes, since there is no nucleus, the mRNA is translated even as transcription continues.

Which feature is characteristic of estuaries

Answers

Final answer:

Estuaries are unique environments where fresh and salt water meet, creating a diluted saltwater habitat. They provide protected areas for the breeding and development of various marine species. The organisms found in estuaries have developed adaptations to cope with the varying salinity conditions.

Explanation:

The main characteristic of estuaries is that they are biomes where a source of fresh water, such as a river, meets the ocean. As a result, both fresh water and salt water are found in the same vicinity, and their mixing creates a diluted (brackish) saltwater. This makes estuaries unique and complex environments that host a variety of marine and terrestrial organisms.

Another specific feature of estuaries is that they act as breeding grounds and nurseries for various marine species such as crustaceans, mollusks, and fishes. These species have developed behavioral and physiological adaptations to cope with the rapidly changing salinity conditions that occur in estuaries. For example, many estuarine plant species are halophytes, meaning they can tolerate salty conditions. Furthermore, some mollusks and clams in this biome have adaptations that allow them to switch between aerobic and anaerobic respiration depending on the salinity and oxygen content of the water.

Final answer:

Estuaries are unique brackish biomes where freshwater and saltwater interact. They house and support various species, which have evolved specific adaptations to handle changing salinity levels. Key factors affecting estuaries' ecological dynamics include tidal shifts and flow rate of freshwater sources.

Explanation:

Estuaries are characterized by the unique intermingling of freshwater and saltwater, creating a brackish water biome where rivers meet the ocean. This environment serves as a protected area and breeding ground for various organisms, including the young offsprings of crustaceans, mollusks, and fish. The salinity in estuaries, which is influenced by the flow rate of freshwater sources and the daily tidal shifts, is a major factor affecting the types of organisms found here and their adaptations to survive.

Both plant and animal species in estuaries have developed various adaptations to deal with the changing salinity. Many estuarine plants are halophytes, which can tolerate salty conditions by filtering out salt from the water they absorb. Mussels and clams, for example, switch from aerobic to anaerobic respiration when exposed to low salinity and revert when high tide returns, increasing the salinity and oxygen content of the water.
