Biodiversity, and Humanity's Threat to Life.
A variation in genetics, species, and of course, an ecosystem level, biodiversity is the single most important thing we must preserve in order for the food chain to be in balance, and for one species to not overtake the scale. This is what makes Earth unique from every other planet on the solar system. Biodiversity provides everyone's needs for food and water, shelter and much more. The importance of this single word is astounding, not only because of the fact that it is needed to conserve humans, but all life on Earth. Biodiversity comes from two words. The first part, "Bio" meaning "life" and the second part, "diversity" meaning "variety". Combine the two, and you have the variety of life.
It is important to understand that biodiversity can be studied on a global scale, or microscopically, genetically, or environmentally. One example is genetic biodiversity in the cross-breeding of dogs, and environmental biodiversity is how diverse the ecosystems around us are. Preserving this is what humans have the task of while living on this beautiful planet. Although humans are widely consumer based, taking from the environment, the question is how much longer can the Earth sustain the rapid population increases while taking and modifying the Earth's environment?
Zooming in on our oceans, which cover over 70 percent of the earth's surface, they are becoming increasingly polluted and threatened each year, with climate change, fishing, commercial agriculture, pollution, and oil spills. Studies show that in 2050, there will be more plastic in the ocean than fish. In the oceans, coral reefs are the most biologically diverse ecosystem in the world, seeing that they have a number of fish communities to tend to. But our reefs are dying, which means less fish, which means less animals that eat the fish, like birds, and less animals that eat the birds, and so on, which I see as a ripple effect, one drop on the pond shakes the whole pond, the whole food chain, the whole scale, but not as much humans.
At the same time, large parts of the Amazon are being cut down and burnt. Tree clearing has cut down the forest by 15 precent already. In Brazil, which has half the forest, 19 percent has disappeared. Those number are just numbers though, but when we have no trees to look at, no flowers to smell, no grass to play in, it will be too late. Many have warned that at one point, the rainforest that contains over 3 million known species, will turn into nothing but a dry scrubland, and we don't have a clue when it will reach it's tipping point.
How can we help? Reducing, reusing, and recycling is just the beginning, started climate strikes, campaigns, and protests is a great way to get started. Volunteering for non-profits that are dedicated to taking young interns to help weed, garden, and grow plants is another effective way. The future depends on us, starts with us, and it is our responsibility to commit ourselves to making sure that we should not need a list to keep track of endangered or extinct species, and we must act now.
Hope this helps!!

During the light reactions of photosynthesis, plants convert light energy into energy the plant can use. Where is the energy stored
Answers
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.

Name at least three neuromitters and state the roles of these neuronmitters in human body ? Except acetylcholine, (GABA)and domanine. Please help as soon .
Answers
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.

Answers
Answer:
you gotta put the small "b" for the female and all the the box will be "Bb"
The dominant allele (black fur) has alleles B and b for the recessive allele (white fur), so the offspring will all have bodies with black fur.
What is phenotype?Phenotype is the physical appearance of characters which is the result of genes which express in the cell to give a particular trait in the diagram black is dominant over white so all the offspring show a black phenotype.
Male genotype: BB
Female genotype: bb
Cross: BB X bb
Gametes: B, B, b, b
All progeny will be black having genotype Bb, Bb, Bb, Bb.
The Cross is uploaded in the image below.
Genotype is the genetic appearance of the allele which shows the gene is responsible for a particular trait.
Therefore, the dominant allele (black fur) having allele B and b for the recessive allele is crossed, and all progeny will be black having genotype Bb, Bb, Bb, Bb.

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
Answers
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

Phosphorus is transpired from the leaves of plants.
Answers
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. 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?
Answers
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.
