What can biodiversity influence within an ecosystem?

Answers

Answer:

People depend on biodiversity in their daily lives, in ways that are not always apparent or appreciated. Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods. Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.  Additionally, biological diversity of microorganisms, flora and fauna provides extensive benefits for biological, health, and pharmacological sciences. Significant medical and pharmacological discoveries are made through greater understanding of the earth's biodiversity. Loss in biodiversity may limit discovery of potential treatments for many diseases and health problems. There is growing concern about the health consequences of biodiversity loss. Biodiversity changes affect ecosystem functioning and significant disruptions of ecosystems can result in life sustaining ecosystem goods and services. Biodiversity loss also means that we are losing, before discovery, many of nature's chemicals and genes, of the kind that have already provided humankind with enormous health benefits.  Biodiversity plays a crucial role in human nutrition through its influence on world food production, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food. Access to a sufficiency of a nutritious variety of food is a fundamental determinant of health..

Alexandra fleming was working with a bacteria called staphylococcus which looked like bunches of grapes under the microscope. He could grow colonies of these bacteria on petri dishes with a growth medium. If mold contains a substance that kills bacteria then...?

Answers

Answer:

In 1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture dishes. He noticed that a mold called Penicillium was also growing in some of the dishes. A clear area existed around the mold because all the bacteria that had grown in this area had died. In the culture dishes without the mold, no clear areas were present.

Fleming thought that the mold must be producing a chemical that killed the bacteria. He decided to isolate this substance and test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution contained all the materials the mold needed to grow. After the mold grew, he removed it from the nutrient broth. Fleming then added the nutrient broth in which the mold had grown to a culture of bacteria. He observed that the bacteria died. He also added the same type of broth that had not been exposed to the mold, to a culture of the same type of bacteria. Nothing happened to the bacteria.

Never Say Never


Carlos slammed the door angrily. He flopped down on his bed and turned on his side, tears streaming down his face. He did not—no, could not— understand why his whole family was pressuring him. It was not like he was going to be a contestant on “Kids in Concert” or some other show that could win them money. It was a stupid school talent show.


In a fog, Carlos let his memories wash over him. He was just five- or six-years old, daring, and uninhibited. He sang tunes from his favorite cartoons and TV shows. He memorized lyrics effortlessly. The family karaoke machine was no match for Carlos. When he finished singing, the living room swelled with applause as family members requested encore after encore.


Carlos was ALWAYS singing. He sang in the car, in the shower, and in the backyard. His family was so used to hearing his serenading that they barely lifted their heads when he passed by. He sang for his closest friends as they walked to the mall, the pool, or the park. He even sang to the family dog, Boomer.


And Carlos had loved it—that is, until now. Last week, his lifetime of confidence collided with catastrophe, and his confidence vanished.


As he remembered he and his friends gathered at the mall, Carlos shuddered. On a dare, Carlos started singing—at first, just loud enough so his friends could hear, but then at their request, louder and louder, until . . . nothing came out.


A wave of panic seemed to overtake him, and suddenly, he froze. Beads of sweat formed on his face as he realized that his natural talent no longer seemed natural.


The look of shock on his face was matched only by the dumbfounded looks on his friends’ faces. At that moment, Carlos sincerely wished that the floor would just swallow him up. To make matters worse, Teresa Mendoza, head of the talent show committee, was there. She did not laugh, but still, she was a judge! As he ran out of the mall, he vowed to avoid her—and everyone else—for the rest of his life.


Now, at home and a week later, a perplexed Carlos had spent hours trying to figure out what had happened. It was as though some evil minion had entered his brain and begun criticizing him for having the foolish notion that he could sing. Having this kind of stage fright was embarrassing and something he had never experienced before. Carlos vowed to never sing in front of others again.


His mother brought him her trustworthy remedy—hot tea with honey. His father suggested that he was just in a “slump” and that, with time, he would again belt out popular songs.


Carlos did not care. They clearly did not comprehend the gravity of the situation. As Carlos continued to lie fuming on his bed, the doorbell rang.


The voice that carried upstairs sounded lively—and female. Who was it? As his curiosity prodded him to peer over the bannister, he heard his mother calling him, announcing the presence of Teresa Mendoza.


Carlos cringed as instinct took over, pleading with him to either dart back up to his room and crawl out the window onto the roof, or dash into the nearest closet. The choices were grim.


Mother’s voice grew closer as she explained that Teresa and Chelsea French, another talent show committee member, were stopping by to be sure that Carlos was planning to register to audition this year.


Huh?


Carlos gradually made his way downstairs as he could scarcely believe his ears. He heard phrases like “only that one time,” “incredible talent,” and “music instructor that would hold practice sessions” as well as a slew of other words that did not register in his brain.


After the women left, his mother smiled at him and said, “See?”


Carlos shook his head and frowned as he glanced at his mother, pride overruling his delight at what was taking place at that moment. But in his heart, he felt just the tiniest of possibilities that perhaps his singing days weren’t over after all.

what kind of currents bring warm air to land?

Answers

Answer: A warm current is just the reverse. A warm current is moving away from the Equator toward the poles. The water in a warm current is warmer than the surrounding water.

Explanation: The surface water temperature varies considerably between the Equator and the poles. As the ocean water is distributed across the Earth's surface by drifts and currents (see the infrared satellite photo of the warm Gulf Stream moving north along the east coast of Florida), warm water from the lower latitudes is moved into the higher latitudes and cold water is moved Equatorward. If you will remember, we noted in the section on Latitude that this redistribution of heat by ocean water is one of the major ways excess energy is moved poleward (and cold water is moved Equatorward).

Which gas does not occur naturally in the atmosphere in any amount but was solely created by human activity? Support your answer with evidence from the chart.

Answers

Answer:

Carbon monoxide.

Explanation:

Carbon monoxide is a gas that consists of an oxygen and a carbon to be able to fulfill the complete molecule, it is a potentially dangerous gas for life on this earth.

On the other hand, what differentiates it from carbon dioxide is that it has two oxygens that are coupled with a carbon to fulfill the complete molecule.

Both gases are pollutants, and produced by man, it is considered that these in high partial pressures in the atmosphere generate a mortal potential for humans since they have more affinity with the hemoglobin protein that is the human gas transporter par excellence, the which oxygenates the tissues.

If the oxygen drops in partial pressure and these toxic gases increase, the hemoglobin having a higher affinity will bind to them and toxify the human body, preventing oxygenation.

The colored shape that Gillian will not need for her model of the electron transport chain is the orange circle. Thus, the correct option for this question is B.

What is Cellular respiration?

Cellular respiration may be defined as a type of chemical process through which oxygen is utilized in order to make energy in form of ATP from carbohydrates mostly glucose that was synthesized during photosynthesis.

The electron transport chain receives electrons from NADH and FADH2 in the mitochondrial matrix. So, electrons, ATP, and NADH, FADH2 are involved in her model of the electron transport chain which is represented by a small yellow circle, yellow star, and green oval respectively.

Therefore, the orange circle is the colored shape that Gillian will not need for her model of the electron transport chain. Thus, the correct option for this question is B.

What is photosynthesis?

Photosynthesis is the process by which green plants convert light energy from the sun and carbon dioxide into glucose and oxygen in the presence of chlorophyll.

As a result, the false assertion about photosynthesis is carbon dioxide is produced during photosynthesis. Photosynthesis is a process that takes place in the chloroplast organelle of plant cells.

The typical light reaction of photosynthesis occurs within the chloroplast's thylakoid membrane. Water and carbon dioxide are the primary reactants in the reaction. In the reaction, the water is oxidized, releasing oxygen as a byproduct. Carbon dioxide is reduced.

Therefore, the correct option is d, Cambium will go through a period of accelerated mitosis.

filtered polluted water. What conclusion can be made
based on these observations?

Answers

Answer:

The unfiltered polluted water is not clear and is yellowish in color. The filtered polluted water is clear with a little bit of yellow color. The pH readings are beyond the range in which organisms can grow. Based on these observations, I can conclude that even though water may look clean, it could actually not be clean or it can still be harmful to living things.

The undesirable products present in the water are known as pollution. The things which cause the pollution is called a pollutant.

The products are as follows:-

The ph helps to check the concentration of the water. The ph of filtered water and unfiltered water is very different.

The ph of filter water is slightly acidic due to the presence of more H+ ions. while the ph of the unfiltered water is basic due to the presence of more nutrients.

Growing up, he was very much inspired by his older brother Matthew, who won a silver medal in the 200-meter dash at the 1936 Olympic Games, to pursue his talent and passion for athletics. He attended John Muir High School and then went on to Pasadena Community College, where he played football, basketball, track, and baseball. From there, Jackie went on to the University of California, Los Angeles, where his time was cut short due to financial hardship. After leaving the University of California, Jackie served in the United States Army. Fortunately, Jackie never saw combat; however, other circumstances ultimately led to Jackies honorable discharge from the military. It was shortly thereafter that Jackie began his career in Major League Baseball.During this time, the leagues were still segregated. Jackie was drafted by Branch Rickey to change all of that and integrate baseball. On April 15, 1947, Jackie became the first African-American athlete to play in the major leagues. Despite the ongoing racism that Jackie faced from some teammates, crowds, and players from other teams, he earned the National Leagues Most Valuable Player award in 1949. In his decade-long career with the Dodgers, Jackie helped his team win the National League pennant several times.
