Answers

Answer:

osteomalacia

Explanation:

Osteomalacia is the disease in which bones become abnormally soft, mainly due to a deficiency of calcium and phosphorus, usually related to a vitamin D deficiency, and can increase the risk of developing osteoporosis.

The disease in which the bones become abnormally soft due to a deficiency of calcium and phosphorus in the blood, necessary for bone mineralization, is known as osteomalacia. In adults, this condition is often caused by a vitamin D deficiency, leading to reduced bone mineral density and an increased risk of osteoporosis. While osteoporosis involves the bones becoming brittle, fragile, and thin, often resulting from a lack of calcium in the diet, osteomalacia specifically refers to the softening of the bones. Rickets is a similar condition that affects children and is also most commonly caused by a lack of vitamin D, but can also stem from deficiencies in phosphorous or calcium.

Answers

Systems thinking focuses on the role of individual elements and their relationship with others in the system.

1. Systems thinking focuses on the ways in which systems interact with the environment.

2. An event that benefits one part while weakening another.

3. Human behavior causes a lot of issues with the ocean.

1. Systems thinking focuses on the ways in which systems interact with the environment. Therefore option C is correct.

Systems thinking is an approach that emphasizes understanding and analyzing systems as a whole, rather than focusing solely on the individual parts.

It recognizes that systems are composed of interconnected elements that interact with each other and their environment and that understanding these interactions is essential for understanding the behavior and dynamics of the system as a whole.

2. An event that benefits one part while weakening another. Therefore option C is correct.

Positive feedback in a system refers to an interaction or process that amplifies or reinforces a certain condition or behavior within the system. It is characterized by a chain reaction where the initial change leads to further changes that intensify the original condition.

Unlike negative feedback, which tends to stabilize or balance the system, positive feedback drives the system toward a specific direction or outcome.

3. Human behavior causes a lot of issues with the ocean. Therefore option B is correct.

Social science intersects with marine science because human behavior plays a significant role in influencing and impacting the oceans.

The study of marine science focuses on understanding the physical, chemical, biological, and ecological aspects of the ocean and its ecosystems.

However, human activities, such as pollution, overfishing, habitat destruction, and climate change, have profound effects on marine ecosystems.

During photosynthesis, within the plant cell, the water is oxidized as it loses electrons. This transforms the water into oxygen.

During transpiration in plants, the water eventually released to the atmosphere as vapor via the stomata present in leaves.

What is transpiration?

It is the process of water loss in plants through evaporation from the stomata of plants.

During transpiration, the water near the surface of the leaves changes into vapor and evaporates when stomata are open.

Transpiration provide the water needed to plants for photosynthesis.

Soils composed mostly of primary minerals will tend to have a higher percentage of _____ and a lower percentage of _____ than soils composed mostly of secondary minerals.

Answers

Answer:

sand; clay

Explanation:

Soils composed mostly of primary minerals will tend to have a higher percentage of sand and a lower percentage of clay than soils composed mostly of secondary minerals.

Soils are porous medium that are made up of minerals, organic matter, water, gases, and microorganisms. Soils are mostly composed of minerals (about 45% to 49%) which are derived from two main mineral types; primary and secondary minerals. Primary minerals are usually derived from igneous and metamorphic rocks in soil, while secondary minerals are produced from the weathering of the primary minerals. Soils that contain mainly primary minerals usually have high amount of sand and silt, and a low amount of clay than soils that contain mainly secondary minerals. Examples of primary minerals are K-feldspars (such as sanidine and orthoclase), and micas (such as biotite).

In recombinant DNA methods, the term vector can refer to _____.

Answers

Answer:

reverse transcriptase

Final answer:

In recombinant DNA methods, a vector is a DNA molecule that functions as a vehicle to carry foreign genetic material into a host cell. Vectors can be plasmids, viruses or artificial chromosomes, and must have the ability to replicate within host cells and contain recognition sites for restriction enzymes and selectable markers.

Explanation:

In recombinant DNA methods, the term vector can refer to a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be reproduced. Examples of vectors include plasmids, viruses, and artificial chromosomes such as yeast artificial chromosomes(YACs).

A vector must have three important characteristics: ability to replicate within host cells, recognition sites for restriction enzymes, and selectable markers which allow cells containing vectors to be selectively cultured.

It's the vector's ability to reproduce within the host cell that allows the foreign DNA to be replicated in the process. In other words, it's a medium through which we can produce multiple copies of a particular piece of DNA within a host organism. The DNA typically inserted into these vectors is often genes that a scientist wants to express (have the cell produce copies of them)

The Meselson-Stahl experiment provided the necessary evidence to discover the mechanism by which DNA replicates. They accomplished this discovery by first culturing DNA with the heavy 15N nitrogen isotope. They then allowed the "heavy" DNA to replicate with DNA grown in normal 14N nitrogen. The density of each generation of replicated DNA was recorded by marking its position in a test tube after centrifugation. The position of each generation was then compared to the positions of pure 15N DNA and pure 14N DNA. Suppose that the first generation after replication revealed two bands after being centrifuged: one at the pure 14N mark, and one at the pure 15N mark. Which method of replication would this observation support? (2 points) A. Dispersive replication B. Conservative replication C. Semiconservative replication D. Another generation would be needed in order to find a viable mechanism

Answers

Answer:

C. Semiconservative replication

Explanation:

Semiconservative replication is a mechanism of replication. Semiconservative model of replication states that in daughter cell, with new double-stranded DNA (cell after replication and mitosis) one strand is from the original template molecule while other is newly synthesized.

This is possible thanks to complementary pairing in DNA (each original strand of double-helix DNA is used as a template for the synthesis of the new strand).

Final answer:

The scenario presented in the question supports the Conservative replication model of DNA replication. In this model, the original DNA strand remains intact, and a completely new strand is synthesized. However, in the actual Meselson-Stahl experiment, they observed support for Semiconservative replication.

Explanation:

The observation described in the question would support the Conservative replication model of DNA replication. According to the Conservative replication model, the parental DNA strand remains intact, and an entirely new strand is synthesized. Thus, after one round of replication, you would observe one band of DNA at the 15N position (the original, 'heavy' parental molecule) and a separate band at the 14N position (the completely new molecule).

The Meselson-Stahl experiment is a classic in molecular biology, used to elucidate the mechanism by which DNA duplicates itself. The result described isn't what they observed, though, rather they saw a single band intermediate between 15N and 14N after the first replication, supporting the idea of Semiconservative replication: each new DNA molecule consists of one old strand and one new strand.

What stimulates the ribosome to move down one codon?

Answers

Answer:

The chain moves from the 5' - 3' direction caused by the use of GTP and several protein-enzyme complexes. As the polypeptide chain is produced the t-RNA move from site A to site P, and then are released into the cytoplasm. The polypeptide chain continues to grow, and is held to the ribosome by the t-RNA at the P site.

Explanation:

Final answer:

The ribosome moves down one codon during the translation process in protein synthesis through translocation, which is powered by GTP hydrolysis and the action of EF-G. This step is crucial for the ribosome to read mRNA and synthesize proteins accordingly.

Explanation:

What stimulates the ribosome to move down one codon is a process called translocation, which is an essential part of the translation phase of protein synthesis. During translocation, the ribosome moves along the mRNA molecule towards the 3' end by a distance of one codon (three nucleotide bases). This movement is facilitated by the hydrolysis of Guanosine triphosphate (GTP) and requires the action of elongation factor-G (EF-G), also known as translocase. As a result of this, the tRNA that was in the A site moves to the P site, carrying the growing polypeptide chain, and the deacylated tRNA in the P site moves to the E site and is then released into the cytosol.

At the end of the translation process, when a stop codon is reached, release factors will bind, causing the polypeptide to be released and the ribosomal subunits to disassociate. The ribosome can then be reassembled for another round of protein synthesis.

Elephants are not the most abundant species in African grasslands, yet they influence community structure. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of the elephants. Take away the elephants, and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grasslands. Why elephants are the keystone species in this scenario?

Explanation:

Elephants are large mammals. Elephants in Africa have a height of 4 meters and weigh up to 7 tons.

The role of elephants in the ecosystem is very important especially its impact both directly and indirectly on the environment. With a large size and height, other predatory animals such as lions, tigers, coyotes, hyenas do not want to get close to elephants. Elephants are animals that prefer to group. While still breastfeeding will be very protected by the mother for up to 3 years. Elephants have an average age of up to 70 years. Perhaps very few elephants have fallen prey to predators. Thus elephants are animals that indirectly protect other animals in Africa. Things like this also indirectly make grasslands become more fertile and other animal species also become more numerous.

Marie Devers 1I usually dont like to admit this, but at one time I disliked history. My teacher, Mr. Wittmeyer, was wonderful, and the material seemed interesting. When I listened to his lectures, however, I inevitably drifted off, got called on to answer, and had absolutely no clue what to say. 2Last month, we studied the Juch family of Poland. Jennalee Juch was a traveling musician who played her music all over the Austrian countryside. Her biography amazed me because I was a musician who played the piano, and I always wanted to travel across Europe. Suddenly, in my mind, I was a fifteenth-century troubadour packing her belongings and heading to the mountains. Next thing I knew, Mr. Wittmeyer asked me a question about whichever topic the class had moved on to, and as usual, I couldnt answer. 3Thats how I did feel (notice the past tense) about history and social studiesthat isuntil Mr. Wittmeyer gave us a project that changed everything. 4The project required our whole class to visit the library and use the school computer program to research our family histories. Every year, this project is assigned to eighth graders. Everyone always gets excited that his or her family may have come from aristocracy, when in reality most of us came from farmers and commoners and people who were not much different from ourselves. I had a feeling I came from a long line of ancestors who were just like me: average. 5Mr. Wittmeyer directed my classmates and me to the computer laboratory and taught us how to use the program installed on the computers. The program allowed students to search their names to discover information about their ancestors. 6While using the software, I learned that my last name revealed that my ancestors had come from Italy. The computer quickly found links to biographies of my family members who had lived long ago. I learned that one of my relatives had been married to the brother of an Italian prime minister! Because my ancestor was a very high-profile person, information was easy to locate. My ancestor had been a musician. She played something called the harpsichord, a forerunner of the piano. 7I found it difficult to believe that one of my ancestors and I had such an authentic connection. The software showed me a picture of my ancestor, and I immediately noticed a resemblance. I daydreamed about an assembly with my fascinating relatives where we discussed the revolutionary changes between their time and mine. 8At the conclusion of our class period, after my classmates gathered around my computer to witness my gigantic discovery, I made sure to personally thank Mr. Wittmeyer because his project helped me learn to love history.
