Fertile soil is valuable because there is a limited supply. Less than one eighth of land on Earth has soil that are well suited for farming.

The thick, fertile soil of the prairies took many thousands of years to develop.

The two ways that the value of soil can be reduced is help use soil correctly, peanuts were once a corp to help soil, and still can be. The soil value recycle rocks and bedrock.

The value of soil is reduced when it loses its fertility and when topsoil is lost due to erosion. Soil can be conserved through contour plowing, conservation plowing and crop rotation. The thick mass of tough roots at the surface of the soil.

Answer:

Your heart changes its rate depending on the activity, so that it can carry blood to your muscles, and therefore it needs to beat stronger if you are performing some exercise, or not so strong if you are sleeping, for example.

Explanation:

Your heart is continuously beating to keep blood circulating throughout your body.

So, here it is why your heart changes its rate: Its rate changes depending on your activity level; it is lower while you are asleep and at rest and higher while you exercise to supply your muscles with enough freshly oxygenated blood to keep the functioning at a high level.

And how: depending on your activity level, your heart has to pump enough blood to your muscles. Blood carries needed oxygen and other nutrients. Muscles need more blood sugar than any other tissue especially when working hard. To supply your muscles with oxygen your heart needs to beat faster, and this builds up your heart muscles.

Final answer:

The heart rate changes due to the autonomic nervous system's regulatory signals, based on the body's oxygen needs. The SA node controls these changes to ensure adequate blood circulation. External factors and the body's physical state directly influence the heart's operating rhythm.

Explanation:

The heart rate changes in response to the body's need for oxygen. During physical activities or stressful situations, the autonomic nervous system signals the heart to beat faster through the Sinoatrial Node (SA node), also known as the heart's pacemaker. This mechanism ensures that more oxygen-rich blood is circulated throughout the body to meet the increased demand.

Conversely, when the body is at rest or calm, the heart rate slows down, reducing the need for oxygenated blood. Factors such as physical fitness levels, emotional state, and even body position can influence heart rate. For instance, shifting from lying down to standing can cause a temporary increase in heart rate to maintain blood pressure and ensure adequate blood flow.

The heart, located within the circulatory system, is the central pump that drives blood through a network of arteries and veins, delivering nutrients and oxygen while removing waste products. It operates through rhythmic contractions controlled by intrinsic electrical impulses, regulated by the brain and hormones, illustrating the interconnectedness of the circulatory and nervous systems.

All DNA of creatures is made from the same materials, and is largely the same. (Humans are less than 5% different than primates genetically)

Studying DNA of different species reveals that all life on Earth shares a common ancestor, due to universal genetic similarities. Genomics has enabled the construction of the 'tree of life' illustrating these relations. Molecular evidence, such as genome comparisons, helps us understand the evolutionary connections among diverse organisms.

Studying the DNA of different organisms provides evidence that all life on Earth is related because all extant life shares a common ancestor. This is visible in the fundamental similarities at the molecular level, such as the universal genetic code, the use of DNA to store genetic information, and the usage of similar molecular building blocks. Genomics and genetics have made it possible to construct the 'tree of life', a diagram illustrating the relationships among organisms by examining nucleic acid sequences that they have in common. This shows the deep connections across all living organisms, from the molecular level to larger structures and functions.

The genomes of various organisms show that they share a high degree of similarity in DNA sequences which code for proteins and other molecules. Through detailed analyses of these genetic codes, scientists have been able to determine homologies that imply a common ancestor. As evolution progressed, the genetic code established early in Earth's history evolved into the diverse life forms observed today. Additionally, molecular evidence of evolution, such as the comparison of genomes, sheds light on how evolution occurs and the relationships among species.

Explanation:

OPTION B. The main function of light-dependent reactions in photosynthesis is to capture and convert light energy into chemical energy (ATP and NADPH), which will then be used to build sugars in the light-independent reactions.

The function of the light-dependent reactions, which occur in the thylakoid membranes of the chloroplasts in plants, is to capture and transfer energy into a usable form. During these reactions, light energy is converted into chemical energy, specifically ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). ATP and NADPH are then used in the light-independent reactions (the Calvin cycle) to build sugars.

The other options presented are not primarily functions of the light-dependent reactions. They do not directly form water molecules or release carbon dioxide yet contribute indirectly by capturing energy used in other processes that could involve these functions.

Answer:

Central

Explanation:

Sensory and motor neurons are connected to the central nervous system.

The central nervous system (CNS) is the section of the nervous system that is made up of the brain and spinal cord. The sensory and motor neurons are connected to the central nervous system. The sensory neurons receive impulses (message) and transmit them from the sense organs to the brain or spinal cord, while the motor neurons transmit impulses from the brain and spinal cord to muscles or glands within the body.

Sensory and motor neurons are both linked to the peripheral nervous system. Sensory neurons transport information from the body's tissues and organs into the central nervous system, while motor neurons transmit signals from the central nervous system to the body's muscles, glands, and organs.

Sensory and motor neurons are connected to the peripheral nervous system. In detail, the peripheral nervous system consists of the nerves and ganglia that lie outside the central nervous system, which includes the brain and spinal cord. Sensory neurons bring information from the body's tissues and organs into the central nervous system, which helps us react to stimuli. In contrast, motor neurons carry signals from the central nervous system to the muscles, glands, and organs in the body to trigger actions like muscle contraction or gland secretion.

Answer: Some non specific responses in the body caused by the immune system are the release of body cells. (T-cells, T-killer cells, B-cells, B-Helper cells.)

Explanation:

When your body notices an intruding viruses or bacteria, it initiates a chemical response. (Aka your germacide.) You body has two systems that’s work together to kill these intruders, your non specific defense, and you specifics defense. Each has it’s own jobs. The non specifics job is to release you cells to the targeted area. When a cell is detected, and it gets into your blood your B cells will latch onto it and call your other cells to come kill it. Another way you’re non specific defense gets to work is your skin. You body always has germs on its skin, so it produces a anti germ liquid. Sometimes it doesn’t affect them, and sometimes it does. For the germs it attacks, it actually breaks down the cells cell. It’s like a acid for the germ.

C. The population will increase in variety over time

Explanation:

If a population has a high level of genetic variety, that will result in even grater genetic variations as the times goes on. With the increase in genetic variation in the population, gradually new species will start to emerge from it, thus speciation will occur. This will happen because the greater genetic variations will enable some of the population to be able to use some other food sources over time, and if that is advantageous than those individuals will start to slowly move in other direction, thus becoming a separate species.

Answer:

The frequency of the incoming light wave is at or near the energy levels of the electrons in the matter. The electrons will absorb the energy of the light wave and change their energy state.

Explanation:

Final answer:

Absorbed light energy is typically converted into heat or another form of energy by the object absorbing it. Objects appear colored due to the reflection of certain wavelengths, while those absorbed contribute to energy transformation within the object.

Explanation:

What Happens to Absorbed Light Energy

When a light wave is absorbed by an object, the absorbed light energy is converted into other forms of energy, typically heat. This transformation is a result of light interacting with matter. For instance, pigment molecules in plants absorb visible light for photosynthesis, while materials like glow-in-the-dark plastics can absorb light energy and later re-emit it as phosphorescence. The energy from light that's absorbed can also contribute to an object's temperature increase.

Moreover, the absorption of light depends on the wavelengths of light and the material it interacts with. Objects appear colored because they reflect certain wavelengths while absorbing others. For example, a red apple appears red because it reflects red wavelengths and absorbs others.

Answer:

Both psudopodes and flagella are used for movement, but only psudopodes are used to engulf food.

Both pseudopods and flagella are used for movement. Pseudopods are temporary and used to engulf food, while flagella are hair-like structures used for locomotion in dinoflagellates.

The question pertains to the comparison of pseudopods in sarcodina and flagella in dinoflagellates. The correct answer to the question is that both pseudopods and flagella are used for movement, but only pseudopods are used to engulf food. Pseudopods are temporary, foot-like extensions of the cytoplasm enabling sarcodina to move and capture prey. Conversely, flagella are long, hair-like structures that allow dinoflagellates to move through their aquatic environments. While flagella contribute to the locomotion of dinoflagellates, they are not involved in engulfing food.

squeeze the fingers of the glove because of imcrease pressure

Answer:

Place the glove in the sun

Explanation:

According to the ideal-gas law:

PV=nRT (1)

References:

P= Pressure

V= Volume

T=Temperature

n= Mol

R=Constant

As it is described , the amount of air inside the glove is constant, so R and n are constants and the ideal-gas formula can be re-written as follows:

V=aT/P (2)

Being "a" a constant.

We can see in (2) that the volume can be incresed directly by increasing the temperature or by lowering the pressure. So the correct answer is "place the glove in the sun" because the temperature of the air will be increased and the volume of the glove will be increased as well.

It is easy to think that by squeezing the fingers of the glove the volume is increased, but in this case the volume of the glove is decreased (because it hasn't got the volume of the fingers anymore) and the pressure is increased in consequence, making the rest of the glove swell in order to maintain the original volume.
