Which describes a way in which phosphorus may enter into the phosphorus cycle?
Earthquakes release phosphorus.
Phosphorus is carried in the rain that was evaporated from lakes.
Human use of fertilizers release phosphorus into the groundwater.
Phosphorus is transpired from the leaves of plants.
Answer:
I think the correct answer from the choices listed above is option C. A way in which phosphorus may enter into the phosphorus cycle is that when human use of fertilizers release phosphorus into the groundwater. Hope this answers the question. Have a nice day.
Human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle. Therefore, the correct statement is option C.
What is the use of phosphorus?Phosphorus is a nutrient needed by plants to grow, and it is added to soil in the form of fertilizers. When it rains, the phosphorus is washed away from the soil and carried into nearby rivers, lakes, and groundwater.
The phosphorus is then taken up by plants or become part of the sediment at the bottom of bodies of water.
Phosphorus can be transformed from there and recycled through the different parts of the phosphorus cycle, such as weathering, erosion, and sedimentation. Phosphorus can also be released from the decomposition of organic matter.
Therefore, human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle.

1. The first person to observe cells was?
Answer:
robert hooke
Explanation:
1. Juan es un estudiante joven que hace poco se mudó a su propio departamento. Realiza actividad física desde siempre pero últimamente nota que se cansa más rápido, tiene poca fuerza y ha perdido algo de peso. No entiende la causa porque sigue comiendo en forma abundante. Visita a su médico, quien le informa que tiene pérdida de masa muscular y le pregunta si está alimentándose correctamente. ¿Por qué le hace esta pregunta? ¿Qué tiene que ver la comida con el músculo?
Answer:
Es posible que Juan sospeche que no está alimentándose correctamente (comer en grandes cantidades no significa estar bien alimentado)
Explanation:
Las proteínas representan un macronutriente esencial que debe ser consumido a través de la dieta para crecer en masa muscular y también para mantener la masa de los músculos. Las proteínas están compuestas por muchos tipos diferentes de aminoácidos (los bloques de construcción de las proteínas), pero solamente 20 aminoácidos conforman las proteínas que se encuentran en el cuerpo humano. Los aminoácidos esenciales son aquellos que el cuerpo no puede sintetizar por sí solo. Estos aminoácidos esenciales son: histidina, fenilalanina, treonina, lisina, metionina, triptófano, valina, isoleucina y leucina. El consumo diario recomendado por la Organización Mundial de la Salud (OMS) de proteínas en un hombre adulto es 0,8 a 1 gramo por kilogramo de peso corporal. Además, es posible que el cansancio que experimenta Juan se deba a alguna deficiencia en micronutrientes esenciales, es decir, debido a la falta de vitaminas y minerales, los cuales también deben ser consumidos a través de la dieta. Por ejemplo, la fatiga puede deberse a la falta de hierro, un mineral fundamental cuya deficiencia lleva a cuadros severos de anemia. Similarmente, la deficiencia en vitamina D puede también causar agotamiento o fatiga crónica, entre otros síntomas (por ej., abruptos cambios en el estado de ánimo, debilidad ósea en los huesos, daño en el estómago, etc). Por otra parte, es importante remarcar que no se debe descartar la posibilidad de que el cansancio experimentado por Juan se deba a un cuadro de estrés y/o algún otro tipo de problema de salud, siendo por lo tanto necesario una descripción más detallada del cuadro clínico para obtener una conclusión más precisa de su situación.

Describe and distinguish between the sources of energy utilised by the brain and heart under well-fed and starvation conditions.
Answer:
Brain ----- glucose and amino acids.
Heart ------- fatty acids and triglycerides.
Explanation:
The sources of energy utilized by the brain is glucose under well-fed whereas the sources of energy utilized by the heart under well-fed condition is fatty acids. During starvation, the source of energy used by the brain is amino acids from skeletal proteins when glucose is not available while on the other hand, during starvation, the heart utilized triglycerides as a source of energy in the absence of fatty acids.

Name at least three neuromitters and state the roles of these neuronmitters in human body ? Except acetylcholine, (GABA)and domanine. Please help as soon .
Answer:
Explanation:
The chemical messengers present in the body are known as neurotransmitters. These are the chemicals that the nervous system uses to send and receive information between neurons and muscles. A neurotransmitter can have one of three effects on a neuron:
Excitatory effect, Inhibitory effect, and/or Modulatory effect.
The list of neurotransmitters and their roles are as follows:
Glutamate: This is present in amino acid compounds which are located in the synapses. It functions as an excitatory neurotransmitter, causing neurons to discharge instructions when stimulated in the central nervous system.
Adrenaline: It helps to respond to body's psychological stress and protection mechanism. They are positioned above the kidney and are created by the adrenal glands. They operate throughout the central nervous system and swiftly increase your heart rate and provide oxygen to your muscles.
Serotonin: Serotonin is a crucial brain neurotransmitter that also has a role in the small intestine. In your digestive tract, serotonin increases feelings of contentment after eating and controls your appetite. When you eat anything that doesn't agree with your stomach, serotonin assists your body in getting rid of it.

If the pair of materials listed below were rubbed together, give the charge that each would have in the same order as listed. use short-form P and N. silk and paraffin wax
Answer:
Simply put, the property of electron affinity refers to the relative amount of love that a material has for electrons. If atoms of a material have a high electron affinity, then that material will have a relatively high love for electrons. This property of electron affinity will be of utmost importance as we explore one of the most common methods of charging - triboelectic charging, also known as charging by friction or rubbing.
Suppose that a rubber balloon is rubbed with a sample of animal fur. During the rubbing process, the atoms of the rubber are forced into close proximity with the atoms of the animal fur. The electron clouds of the two types of atoms are pressed together and are brought closer to the nuclei of the other atoms. The protons in the atoms of one material begin to interact with the electrons present on the other material

Which type of current occurs when surface water on the ocean becomes denser than the water below it and sinks?
During the light reactions of photosynthesis, plants convert light energy into energy the plant can use. Where is the energy stored
Answer:
Photosynthesis is a process where plants and other organisms convert energy from the sun into a chemical energy that through cellular respiration can be later released in order to fuel the organism's metabolic activities.
The energy which is stored in the form of sugar is broken down into starch entering the mitochondria to produce energy. The energy is stored in the chemical bonds. To obtain the energy, organisms take energy-rich compounds such as glucose and breaks them down to release their energy. The organism traps the released energy and stores it in a form of adenosine triphosphate or ATP.
