How has modern humans
ecological footprint caused a Tragedy of the Commons?
Answer and Explanation:
The ecological footprint is an indicator of sustainability at an international level that integrates all the human impacts over the environment, considering the necessary resources and the generated residues to maintain the modern consumption model. It refers to the productive ecological surface needed to produce resources to consume by one person and to absorb the residues that are produced.
By constant contamination and indiscriminately use of natural resources the impact generated by human in the earth is unmeasurable.
The tragedy of the commons refers to how some people, acting by their own needs or interests, may exceed the use of natural resources, affecting their population and, therefore, other users. These individuals over explode resources thinking only in the present, but not in the future.
The ecological footprint as an indicator makes visible the unsustainable lifestyle of human beings, especially those of the first world. If this lifestyle would project to the rest of the world equally, natural resources would completely disappear. More developed countries are over contaminating and over exploding natural resources, affecting other countries of the third world, and even themselves.
Conlan wants to answer the question, “Does phosphorus affect tomato fruit production?” Which statement represents a hypothesis that he can test to answer his question?
Provided question lacks the group of choices to answer the question, however, the correct group of choices are given below:
A)If phosphorus affects tomato fruit production, then tomatoes that are fertilized with phosphorus will have larger leaves.
B)If phosphorus affects tomato fruit production, then phosphorus should be added to the soil during planting.
C)If phosphorus affects tomato fruit production, then adding phosphorus to the soil will make tomatoes taste better.
D)If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes.
Answer:
The correct answer would be option D) )If phosphorus affects tomato fruit production, then plants that are fertilized with phosphorus will produce more tomatoes.
Explanation:
To answer the question of Conlan, “Does phosphorus affect tomato fruit production?” he should form a hypothesis that can test the amount of the phosphorus and amount of the production of tomato fruits.
Productivity of fruits dealt with the producing tomato fruit instead of their taste, or size of leaves. So the statement D represent the hypothesis for his question due to the fact that phosphorus can increase the capacity of tomato fruit production.
Thus, the correct answer is option D.

Consider an experiment in which starch is dissolved in a liter of water. Some of the solution is placed into a securely tied dialysis bag. The dialysis bag is placed into a beaker containing distilled water and iodine for 30 minutes. What are the correct answers for the questions below? (Note: Iodine reacts with starch to create a black/purple color.) What would happen to the color of the solution in the bag? a. The solution in the bag would turn purple as the iodine reacts with the starch. b. The solution in the bag would grow lighter as the starch leaves the bag and enters distilled water and iodine.
Answer:
a. The solution in the bag would turn purple as the iodine reacts with the starch.
Explanation:
According to this question, a solution containing starch is placed into a securely tied dialysis bag. The dialysis bag is then placed into a breaker containing distilled water and iodine for 30mins.
The starch is a solute substance, which when added to the solution in the dialysis bag makes the solution in the bag HYPERTONIC in comparison to the hypotonic (low solute concentration) distilled water+iodine in the beaker. Based on this concentration gradient (difference in concentration), osmotic flow will occur across the dialysis bag (semi-permeable membrane).
Note that, osmosis is the movement of water from a region of low solute concentration to a region of high solute concentration across a membrane. Hence, water+iodine from the breaker will move into the solution in the dialysis bag.
Because the solution entering the dialysis bag contain iodine, it will react with the starch content of the dialysis bag and form a dark purple coloration inside the dialysis bag.

6. Los seres humanos producen desechos celulares que salen del cuerpo gracias a diferentes procesos de los cuales están a cargo varios sistemas, selecciona uno que NO haga parte de este proceso: A. Sistema urinario B. Sistema respiratorio. C. Piel. D. Sistema reproductor.
Answer:
D. Sistema reproductor.
Explanation:
La excreción es el proceso de eliminar los desechos y el exceso de agua del cuerpo. Estos desechos pueden ser dañinos y pueden causar daños.
Los órganos responsables de la excreción son el riñón, los pulmones, la piel, el hígado y el intestino grueso.
La piel elimina el sudor, el exceso de agua y las sales a través de las glándulas sudoríparas.
El sistema urinario está formado por riñón, uréteres, vejiga y uretra. El riñón elimina el exceso de agua y sal al producir orina que luego se transporta con la ayuda de los uréteres, la vejiga y la uretra.
En el sistema respiratorio, los pulmones excretan sustancias gaseosas, como dióxido de carbono y agua.

Explanation:
Son músculos antagonistas (unos realizan flexión y otros extensión) los siguientes: * 5 puntos Trapecio- deltoides Bíceps- tríceps Serratos- rectos Frontal- orbicular
Answer:
Bíceps- tríceps
Explanation:
Los músculos trabajan para generar movimiento mediante la contracción de células musculares. El bíceps y el tríceps son músculos antagonistas presentes en el brazo. Cuando el brazo se acorta, el bíceps funciona como agonista (es decir, se contrae) y hace que los tendones que tiran de los huesos del antebrazo puedan doblarlo. Durante este movimento, el triceps funciona como antagonista, encontrándose en estado de relajamiento. Por otra parte, durante el estiramiento del brazo, las funciones de estos músculos se invierten, con lo cual el tríceps (agonista) se contrae y el bíceps (antagonista) se relaja.

You are a molecule of nitrogen. Choose a starting point in the nitrogen cycle and describe the process you would go through to move through the entire cycle
I am converted by bacteria into ammonia,
from there some things can absorb me, I am further converted by bacteria intonitrates and nitrites, plants assimilate left are further converted into nitrogen gas that is released into the atmosphere where I am breathed in.
hope this helped
please give brainlist
Fixation is the first step in the process of making nitrogen usable by plants. Here bacteria change nitrogen into ammonium. Nitrification - This is the process by which ammonium gets changed into nitrates by bacteria. Nitrates are what the plants can then absorb.

A refrigerator thermometer is read ten times and registers degrees Celsius as:
39.1, 39.4, 39.1, 39.2, 39.1, 39.2, 39.1, 39.1, 39.4, and 39.1. However, the real
temperature inside the refrigerator is 37 degrees C. Is this an example of
precision, accurate, neither, both or neither, Make a selection and explain.
Answer:
Precise, but not accurate
Explanation:
First, let’s define accuracy and precision.
Accuracy: how close you are to the actual value
Precision: how close the measurements are to each other.
Let’s examine the data given:
39.1, 39.4, 39.1, 39.2, 39.1, 39.2, 39.1, 39.1, 39.4, 39.1
Each number is very close to 39, within 0.1 to 0.4.
The actual temperature of the refrigerator is 37 degrees. Each measurement is about 2 away from 37.
Since the measurements are close to each other, but far from the true value, we can say this is precise but not accurate.

What makes up genes? Explain in 1 paragraph please
Answer: Genes are made up of DNA
Explanation: Genes are made up of DNA . to be more precise each gene is made out of possibly 25 000 dna to 2 million dna.
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project estimated that humans have between 20,000 and 25,000 genes.
Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Someone diagnosed with meningitis has inflamed membranes that cover and protect the brain and spinal cord. Meningitis is a result of pathogenic gram-negative bacteria that cause extreme infections when their bacterial cell wall dies and lipopolysaccharide (a lipid and polysaccharide) is released. The lipopolysaccharide is an example of a/an
Answer: ENDOTOXIN
Explanation: Meningitis is a nervous system disorder that occurs when there is an infection and inflammation of the meninges,these meninges are the membranes that cover the brain and the spinal cord,they are the pia mater, dura mater,and the arachnoid mater.
This infection and inflammation of the meninges is causes by inversion of microorganism, bacteria precisely,when these bacteria that are gram negative invade the meninges,the cell wall of the bacteria dies off exposing the cellular contents, this exposure introduces a toxin known as LIPOPOLYSACCHARIDE directly in to the meninges which disrupts the normal functioning of the meninges, infection further sets in and inflammation is triggered as well.
