Answer:
its the ekman spiral not pressure differences between water masses
Explanation:
Upwelling. Along some coasts, the Ekman spiral causes an upwelling of deeper water to replace the water that has moved offshore. The colder, deeper water is richer in nutrients. These upwelling areas contain some of the richest fishing grounds in the world.

Explanation:
What will occur if a species is divided into two groups and allowed to reproduce in different environments for many generations?
Answer:
The original species will diverge into two new species. It will occur speciation. It will occur some sort of allopatric speciation.
Explanation:
When the original species is divided and placed under different environments, where they can reproduce for many generations, many changes or mutations will occur in each group. These changes will depend on each group´s environment and its ecological pressures and will lead to divergence. Pressures act on individuals and make them adapt to the new environmental conditions. Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce. The fixation of mutations will increase the difference among both groups, up to the diverging point into two new species.
The biological concept of species states that individuals of the same species can reproduce because they have a genetic reservoir in common: many genetic variants.
Genetic variability is the measure of a species organism´s tendency to differentiate. In genetic variability, individuals of the same species are not identical. They are recognizable as members of the same species, but they differ in shape, function, and behavior. There exist variations among individuals of the same species.
Genetic variability originates from mutations, recombinations, and karyotype alterations. It allows or makes possible evolution.
Allopatric speciation consists of the geographic separation of a continuous genetic background giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
The process of allopatric speciation involves different steps:
• The emergence of the barrier.
• Interruption in the genetic interchange
• The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
• Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
• Prezigotic isolation mechanisms favored by selection once occurs a secondary contact between the new species in formation.
Answer:
divergence, potentially giving rise to two different species
What factors limit the size of a cell?
Answer:
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.

Answer:
El contenedor que tiene fertilizantes crecerá más.
Explicación:
El contenedor que tiene fertilizantes en dosis óptimas crecerá a un ritmo más alto y producirá más vegetación en comparación con otros contenedores que tienen poco o ningún fertilizante porque los fertilizantes tienen los nutrientes que necesitan las plantas en mayor cantidad para su crecimiento y desarrollo. El fertilizante contiene nitrógeno, fósforo, potasa y algunos otros nutrientes que contribuyen al crecimiento y desarrollo del cuerpo de la planta, por lo que podemos concluir de este experimento que el contenedor con nutrientes crecerá más rápido que otros.

One day, at a certain time, a student measured the shadow of a fence and found that it was 2 m long. The next day, she measured the shadow of the same fence at a different time and found that it was 3 m. long. What can you infer about the time of day at which the student measured the shadows? Explain.
Answer:
The time of day the second time the student measured the length of the fence shadow was either earlier or later than the first time she measured the shadow.
Explanation:
As the first time the student measured the shadow of the fence gave an answer of 2 meters, the second time gave an answer of 3 meters. For this reason, the shadow is longer in length. This means that the sun is closer to the horizon, yielding a light beam that is closer to the ground.
Moreover, if the sun was directly above the fence post, there would be no shadow. However, because the sun is closer to the horizon, showing that it is earlier or later then the first measurement, the second measurement has a longer shadow.

What are the two main phases of photosynthesis called and why?
Answer:
Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase.
Explanation:
In the light-dependent process, which takes place in the grana, the stacked membrane structure within chloroplasts, the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis. The plant uses light energy to generate the co-enzyme Nicotinamide adenine dinucleotide phosphate, or NADPH and ATP, the molecules that carry energy. The chemical bonds in these compounds store the energy and are used during the dark phase
The dark phase, which takes place in the stroma and in the dark when the molecules that carry energy are present, is also known as the Calvin cycle or C3 cycle. The dark phase uses the ATP and NADPH generated in the light phase to make C-C covalent bonds of carbohydrates from carbon dioxide and water, with the chemical ribulose biphosphate or RuBP, a 5-C chemical capturing the carbon dioxide. Six molecules of carbon dioxide enter the cycle, which in turn produces one molecule of glucose or sugar.
The survival function that occurs inside of these structures relies on which three items?
A. sunlight, oxygen, soil
B. oxygen, carbon dioxide, water
C. sunlight, carbon dioxide, water
D. water, xylem, soil
Answer:
This question is incomplete as no structure is portrayed, however, the question can be answered based on general understanding. The answer is
C. sunlight, carbon dioxide, water
Explanation:
The structure being referred to in this question is CHLOROPLAST, which is an organelle in plant cells saddled with the responsibility of making food (sugar) via the process of photosynthesis. In order for the photosynthetic process to occur, three major components or raw materials are needed.
The three items that is relied upon by chloroplast in order to perform its photosynthetic function are sunlight, carbon dioxide (CO2), and water (H2O). The CO2 enters the plant from the atmosphere/air while the H2O is absorbed by the roots of plants. The light is absorbed by certain pigments in the chloroplast called CHLOROPHYLL.
What are two possible changes that might occur in a green insect species if the green grass it uses for camouflage turns brown due to drought
I guess evolution could eventually occur causing the insect species to darken but since it's a drought it's probably a short period
another thing is the species is hunted and dies out. their source of camouflage is gone leaving them out in the open for predators

Answer:
I believe D would be the answer
Explanation:
As in the first part the pseudo podium is engulfing the particle which is more similar to taking food and the next part in the phagosome the particle is engulfed and further the enzymes would be released which would digest the particle hence similar to digestion
During transpiration, water moves through a plant and moves out into the atmosphere through the leaves. Transpiration is the result of the interaction of which two parts of a plant?
Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant.
Transpiration is the outcome of the association between the xylem vessels and stomata present in the leaves.
• The evaporation of water at the surfaces of the spongy mesophyll cells in the leaves succeeded by the loss of water vapor via the stomata is termed transpiration.
• Transpiration generates a pull or tension on the water in the xylem vessels, and these molecules of water are cohesive so pulling up of water takes place through the plant.
• The primary sites of transpiration are the stomates present in the leaves. This stomata comprises two guard cells, which produce a small pore on the leaves' surfaces. These guard cells monitor the closing and opening of the stomates in reaction towards different environmental stimuli, and thus, regulate the loss of water by transpiration.

dangerous chemicals from a nearby mine have entered this lake. How do you think these chemicals will affect the fish in the lake?
Answer:
As a result of daily activities, man has been altering the environment since before recorded history. Increased urbanization, the Industrial Revolution, and an overall larger population base have accelerated the process considerably. While providing numerous societal benefits, modern chemical technology has also brought about a marked increase in the number and variety of chemicals ultimately entering natural surface waters. The last century has witnessed a substantial growth of the chemical industry and it is estimated that there are presently over two million known, chemical compounds in existence, with nearly 250,000 new compounds currently synthesized each year. Of this number, it is estimated that approximately 1,000 new chemicals each year will find their way into the environment as the end result of marketing, use, and disposal.

It is important to learn about, and very interesting. I would still like to learn more about it!
Explanation:
An increase in the concentration of greenhouse gases, like carbon dioxide, in the atmosphere can increase the temperature on Earth. How would such an increase in temperature most likely affect Earth's water cycle?
Answer:
Global warming intensifies water cycle
Explanation:
Global warming can dramatically intensify the water cycle because this phenomenon is associated with an increase in temperature, thereby a higher amount of water is evaporated into the air and a higher amount of ice is melted at the poles. Warmer atmospheric air will have a higher amount of water vapor, increasing the frequency and intensity of rainstorms. In consequence, global warming can significantly increase the probability of flooding in coastal communities.

Can water change the land quickly, slowly, or both? Explain.
Answer: Yes, but slowly
Explanation: Flowing water causes sediment to move. Flowing water can erode both rocks and soil.
Materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesn't matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesn't it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition. Faster-moving water has more kinetic energy. Therefore, it can carry larger particles. It can also carry more particles. What causes water to move faster? The steeper the slope, the faster the water flows. It's just like a toy car rolling down a ramp. It will roll the fastest when the ramp is steep. It will roll slower when the ramp is less steep. If the ramp is flat, it may have no motion. The slope of the land causes water to move faster. If a stream or a river is flowing down a mountain, it will move more quickly. If it is flowing across a flat area, it will move slowly. Some minerals dissolve in water. The minerals are then carried along in the solution. Small particles, such as clay and silt, are carried in suspension. They are mixed throughout the water. These particles are not dissolved in the water. Somewhat bigger particles bounce along the bottom. Particles, such as sand, move in little jumps near the stream bottom. They are nudged along by moving water. The biggest particles move in a different way. They are too big to hop. Instead, they roll along the bottom. Gravel and pebbles move in this way. These particles roll or drag along the bottom of the water.
