distinguishing plate boundaries divergent boundary convergant boundary transform boundary
Answer:
Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.A divergent boundary is where two tectonic plates are moving away from each other. A convergent boundary is where two tectonic plates are moving toward each other. A transform boundary is where two tectonic plates are sliding past each other horizontally.
Divergent Boundary: In this boundary, the plates are being pulled apart by tensional forces. As they separate, magma from the mantle rises to fill the gap, creating a new crust. This process is known as seafloor spreading.
Divergent boundaries are often associated with mid-ocean ridges, underwater mountain ranges formed by the upwelling of magma. On land, they can result in rift valleys, where the Earth's crust is being pulled apart.
Convergent Boundary: In this boundary, the plates are being pushed together by compressional forces. As they collide, one plate is usually forced beneath the other in a process called subduction. Alternatively, if both plates have similar densities, they may compress and buckle, creating mountain ranges.
Convergent boundaries can lead to deep oceanic trenches (associated with subduction zones) and volcanic arcs on the overriding plate. They also create mountain ranges like the Andes and the Himalayas.
Transform Boundary: In this boundary, the plates are moving laterally in opposite directions. The movement is not smooth and can cause earthquakes as the plates get locked together and then suddenly slip past each other, releasing pent-up energy.
Transform boundaries are characterized by prominent fault lines, such as the San Andreas Fault in California, where the Pacific Plate and North American Plate slide past each other.
In summary, divergent boundaries involve plates moving apart, convergent boundaries involve plates coming together, and transform boundaries involve plates sliding past each other horizontally.
These plate interactions play a crucial role in shaping the Earth's surface and are responsible for many geological phenomena and natural disasters.

Because of the presence of both activation and inactivation gates, voltage-gated Na channels can be all of these.
Sodium voltage-gated channels can be either closed, open, or inactive. Voltage-gated sodium channels are closed when at rest. Both an activation gate and an inactivation gate are present in voltage-gated sodium channels. Although the inactivation gate is open, the activation gate is closed. This conformation is closed but capable of opening. Some of the activation gates open as a result of membrane depolarization brought on by a stimulus. Both the activation and inactivation gates will be opened at this point. As sodium ions enter the cells, nearby activation gates will open. A greater amount of sodium will enter the cells as a result, initiating an action potential.Both gates open when certain depolarization thresholds are reached. Action potential increases to its maximum as sodium rushes into the cell. The inactivation gate will gradually close and the permeability of the membrane to sodium ions will decrease. The channel is now in a state known as "closed but not capable of opening." Up until the membrane potential reaches its resting state, this occurs.

The concept of ____ explains why children of parents who are at the extreme ends of a normal (bell-curve) distribution for a phenotype are usually closer to the population average for the phenotype
The concept of regression to the mean explains why children of parents who are at the extreme ends of a normal (bell-curve) distribution for a phenotype are usually closer to the population average for the phenotype.
Regression toward the mean simply means that the likelihood of the subsequent random occurrence being less extreme after an extreme random event is low. Francis Galton was the first to describe regression toward the mean. He carried out a study in 1886 to determine the relationship between children's heights and their parents. After adjusting for the height disparity between men and women (by multiplying each woman's height by 1.08), he measured the heights of 928 adult children and the matching 205 parent couples and discovered something intriguing. The average height of a kid's parents was typically higher than that of the child, but less extreme (closer to the mean). Therefore, the child was frequently shorter if the parents were particularly tall. The child tended to be very tall if the parents were short.learn more about regression to the mean here: https://brainly.com/question/16539587

____________ is translated by the ribosomes and contains the code that specifies the sequence of amino acids in a polypeptide chain.
mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.
A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in translation.
Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for protein synthesis.
The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and protein synthesis is facilitated by this amino acid sequence.
The genetic code, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).
Thus mRNA contains the code that specifies the sequence of amino acids in a polypeptide chain.

Using the idea of concentration gradient explain why the purple colour of potassium permaganate gradually spreads throughout the water in the jar
The purple color of potassium permanganate gradually spreads throughout the water in the jar by the process of diffusion.
Diffusion is the process of movement of a substance from the region of higher concentration to the regions of lower concentration. Diffusion occurs in liquids as well as gases. Potassium permanganate is a purple color compound, when it is added in a jar of water it spreads throughout the water by the virtue of diffusion. The concentration of potassium permanganate is higher at one point and the other regions in the jar have its nil or low concentrations initially, this leads to the set up of a concentration gradient. As time passes diffusion occurs and the particles of potassium permanganate keep on migrating to the regions of low concentration until the concentration is uniform throughout the jar. Ultimately, it spread throughout the jar making the water purple.

Explanation:
"...the process by which organisms combine oxygen with foodstuff molecules, diverging the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water." - Britannica
The gas exchange during cellular respiration involves oxygen moving into cells and carbon dioxide moving out of cells.
During gas change oxygen actions from the lungs to the bloodstream. on an equal time, carbon dioxide passes from the blood to the lungs. This happens within the lungs among the alveoli and a network of tiny blood vessels known as capillaries, which might be located in the walls of the alveoli.
Three strategies are critical for the switch of oxygen from the out of doors air to the blood flowing through the lungs: airflow, diffusion, and perfusion. ventilation is the manner through which air moves in and out of the lungs.

Can u think of three factors which might affect how much energy someone will need
Gender, age and body weight are the three factors.
What are the effects of gender, age and body weight on energy expenditure?Body weight:
Energy consumption while at rest is determined by body size and weight. Due to the higher maintenance costs associated with a larger body, a heavier person has a higher resting energy requirement. The most unpredictable part of overall energy expenditure is activity-induced energy expenditure. Since larger subjects' activity energy expenditure is not higher in proportion to the expense of moving with a higher body weight, smaller and leaner subjects often move more. As a result of changes in body size and body composition, eating causes variations in energy expenditure.
Gender:
In comparison to girls of the same size and age, adult males frequently have 10–20 percent more muscle mass. Because muscle burns more calories than fat, men have greater basal metabolic rates (BMR). As a result, men need 5–10% more energy than women.
Age:
Compared to adults, children and adolescents require more energy for growth and development. As people age, their body composition changes and their energy needs decrease, resulting in a decrease in BMR. As people age, many of them become less active.
