12 km/h × 5h
12 km × 5
60 km
Answer:
\(\boxed {\tt 60 \ kilometers}\)
Explanation:
In order to find distance, use the following formula. Multiply the time by the velocity.
\(d=t*v\)
The time is 5 hours.
The velocity of the cyclist is 12 kilometers per hour.
\(t= 5 \ hr\\d= 12\ km/hr\)
Substitute the values into the formula.
\(d= 5 \ hr * 12\ km/hr\)
Multiply. Note that the hours, or "hr" will cancel each other out.
\(d= 5 * 12 \ km\)
\(d= 60 \ km\)
The cyclist travelled 60 kilometers.

There are two continents with an ocean between them. Today the continents have very different plants and animals on them. However, a geologist found fossils of the same type of organism on both continents. Millions of years ago when this type of organism was alive, we know it lived in only one place. The geologist is using fossils as evidence to argue that the two contients used to be touching. How could the continents have gotten so far apart, and how long did it take for this to happen?
Answer:
A. Through geologic forces leading to continental drift.
B. It can take up to millions of years.
Explanation:
A. Continents rest on tectonic plates (a large slabs of rock). The plates are usually moving and interacting with one another. Seafloor spreading zones and giant rift valleys are the sites where tectonic activity are done.
However, in the process of seafloor spreading, molten rock emerges from within the Earth and produces an oceanic crust (a new seafloor) to the edges of the old one. Seafloor spreading occurs along giant underwater mountain ranges (also referred to as mid-ocean ridges).
Then, as the seafloor grows wider, the continents on opposite sides of the ridge move away from each other over time to experience a define continental drift.
B. The seafloor spreading rates is as low as 2.5 centimeters per year and take up to millions of years to see a well defined drift.

The correct option is C: The concentration at which dsDNA will have the highest Tm is 100 mM.
Which concentration will result in the highest Tm for dsDNA?Out of the given options, the concentration at which double-stranded DNA (dsDNA) will have the highest melting temperature (Tm) is 100 mM. Tm is the temperature at which half of the DNA strands in a double helix become denatured or separated.
It is influenced by factors such as DNA sequence, length, and ionic conditions, including the concentration of ions in the solution. In general, increasing the concentration of salt ions, such as potassium or magnesium, can stabilize the double helix and raise the Tm.
In this context, a concentration of 100 mM is likely to provide an optimal ionic environment for maintaining the stability of dsDNA, resulting in a higher Tm compared to lower or higher concentrations. It is important to note that the Tm can vary based on the specific DNA sequence and experimental conditions.

in c4 photosynthesis, where does the carbon in newly synthesized glucose come from?
The carbon in newly synthesized glucose during C4 photosynthesis comes from the atmospheric CO2 that is initially fixed into oxaloacetate and later released as CO2 again in the bundle sheath cells to be incorporated into glucose through the Calvin cycle.
1. \(CO_2\) enters the leaf through stomata, which are tiny pores on the leaf surface.
2. The\(CO_2\) is initially fixed into a 4-carbon compound called oxaloacetate by an enzyme called phosphoenolpyruvate carboxylase (PEPC) in mesophyll cells.
3. Oxaloacetate is then converted into malate, another 4-carbon compound, which is transported into the bundle sheath cells.
4. In the bundle sheath cells, malate is decarboxylated, releasing \(CO_2\).
5. The released \(CO_2\) is fixed into a 3-carbon compound called 3-phosphoglycerate (3-PGA) by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) through the Calvin cycle.
6. The 3-PGA molecules go through a series of reactions in the Calvin cycle, ultimately generating glucose and other sugars.

Should Zealandia be considered a continent?
Some scientists believe that it should be, while others do not. Use the information you collected to support or reject the claim above. Be sure to cite the evidence you used to classify Zealandia. In addition, include at least two quotes from the text to support your argument. Don’t forget to sum it all up with a concluding sentence.
Claim:
Evidence and Reasoning:
Directions: Read the prompt below. Then, write a well-developed argument to support or reject the claim.
Claim: Zealandia should be classified as a geological continent, rather than an oceanic plate with a collection of continental islands, fragments, and slices.
Explanation:
region of the southwest Pacific Ocean is made up of continental crust. The region has elevated bathymetry relative to surrounding oceanic crust, diverse and silica-rich rocks, and relatively thick and low-velocity crustal structure. Its isolation from Australia and large area support its definition as a continent—Zealandia. Zealandia was formerly part of Gondwana. Today it is 94% submerged, mainly as a result of widespread Late Cretaceous crustal thinning preceding supercontinent breakup and consequent isostatic balance. The identification of Zealandia as a geological continent, rather than a collection of continental islands, fragments, and slices, more correctly represents the geology of this part of Earth. Zealandia provides a fresh context in which to investigate processes of continental rifting, thinning
Earth’s surface is divided into two types of crust, continental and oceanic, and into 14 major tectonic plates (Fig. 1; Holmes, 1965; Bird, 2003). In combination, these divisions provide a powerful descriptive framework in which to understand and investigate Earth’s history and processes. In the past 50 years there has been great emphasis and progress in measuring and modeling aspects of plate tectonics at various scales (e.g., Kearey et al., 2009). Simultaneously, there have been advances in our understanding of continental rifting, continent-ocean boundaries (COBs), and the discovery of a number of micro-continental fragments that were stranded in the ocean basins during supercontinent breakups (e.g., Buck, 1991; Lister et al., 1991; Gaina et al., 2003; Franke, 2013; Eagles et al., 2015). But what about the major continents (Fig. 1)? Continents are Earth’s largest surficial solid objects, and it seems unlikely that a new one could ever be proposed.

Hammer equal area projection.
The Glossary of Geology defines a continent as “one of the Earth’s major land masses, including both dry land and continental shelves” (Neuendorf et al., 2005). It is generally agreed that continents have all the following attributes: (1) high elevation relative to regions floored by oceanic crust; (2) a broad range of siliceous igneous, metamorphic, and sedimentary rocks; (3) thicker crust and lower seismic velocity structure than oceanic crustal regions; and (4) well-defined limits around a large enough area to be considered a continent rather than a microcontinent or continental fragment. The first three points are defining elements of continental crust and are explained in many geoscience textbooks and reviews (e.g., Holmes, 1965; Christensen and Mooney, 1995;
where do plant cells and cyanobacteria (also photosynthetic) get the atp they need to power their regular cellular processes?
Plant cells and cyanobacteria (also photosynthetic) obtain the ATP required to power their usual cellular functions from Cellular respiration.
Plant cells and cyanobacteria are photosynthetic creatures that can produce their nourishment through the process of photosynthesis. They use light energy to transform carbon dioxide and water into glucose and oxygen during this process. However, to fuel their usual cellular functions, including protein synthesis, DNA replication, and cell division, cells require a steady source of energy in the form of ATP.
Cellular respiration produces the ATP necessary for plant cells and cyanobacteria. While photosynthesis generates glucose and oxygen, cellular respiration breaks down glucose molecules to release energy as ATP. This occurs in the mitochondria of plant cells and cyanobacteria. Glycolysis, the Krebs cycle, and oxidative phosphorylation are the three steps of cellular respiration. The first stage, glycolysis, involves the breakdown of glucose molecules into pyruvate, which releases a tiny quantity of ATP.
Pyruvate is transformed into acetyl-CoA in the Krebs cycle, which then enters a loop of reactions that creates additional ATP and carbon dioxide. Finally, electrons from the Krebs cycle are passed via a series of protein complexes in the third stage, oxidative phosphorylation, to form a proton gradient across the mitochondrial membrane. This gradient is then used to drive the production of ATP.
While photosynthesis also produces ATP through light reactions, this ATP is primarily used to power the photosynthesis itself, rather than the regular cellular processes of the plant cell or cyanobacterium. Therefore, the correct answer to the question is Cellular respiration.

Explanation:
during exercise, when you increase the intensity of your exercise (increase speed or power output), which bioenergetic pathway starts producing atp immediately to provide for the immeidate increased atp demand?
During exercise, when you increase the intensity of your exercise the "Phosphagen system" bioenergetic pathway starts producing ATP immediately to provide for the immediate increased ATP demand.
Phosphagen system is the only energy system which produces energy in the absence of oxygen. This system is also called ATP-CP (Adenosine triphosphate – Creatine Phosphate) system which helps in immediate energy production. It is an anaerobic process in which ATP is produced from the breakdown of creatine phosphate.
The phosphate group is transferred from the creatine phosphate to ADP (Adenosine diphosphate) to produce ATP (Adenosine triphosphate) which can be used for immediate energy. The ATP produced by this system is utilized immediately and in less than 10 seconds, all stored ATP is used up. Therefore, the phosphagen system provides energy for short periods and it is primarily used for short bursts of high-intensity exercises, such as sprinting and weightlifting.

Neurons carry information from sense organs to the spinal cord and brain. In the brain,
carry information from the sensory neurons
Neurons carry information from sense organs to the spinal cord and brain. In the brain, interneurons carry information from the sensory neurons.
Neurons are specialized cells in the nervous system that transmit signals and information. Sensory neurons are responsible for carrying information from the sense organs (such as eyes, ears, skin) to the spinal cord and brain. They convert sensory stimuli into electrical signals, which are then transmitted along their long projections called axons.
Once the sensory information reaches the brain, it needs to be processed and integrated. This is where interneurons come into play. Interneurons are a type of neuron that resides entirely within the central nervous system, including the brain. Their role is to receive signals from sensory neurons and transmit them to other neurons within the brain. They act as connectors or relays, forming neural circuits and facilitating communication between different regions of the brain.
Interneurons play a crucial role in processing sensory information, integrating it with existing knowledge and memories, and generating appropriate responses. They allow for complex neural processing and contribute to the overall functioning of the brain. Thus, interneurons serve as an essential link between sensory neurons and other neurons in the brain, enabling the interpretation and response to sensory information.

Restriction enzyme Compared to enzyme II, I will have more restriction sites.
The base makeup and length of the recognition site determine how frequently a specific restriction site can be found in any DNA. For instance, a G base follows a C base in mammalian genomes significantly less frequently than would be predicted by chance. Therefore, mammalian DNA is less commonly cut by restriction endonucleases like Nru I than it is by DNA from bacterial sources with more randomly distributed bases. Nru I recognizes the sequence TCGCGA.
