What do all forms of active transport have in common?
Answers
Answer:
-Using ATP
Explanation:
Cells use various mechanisms to move substances across their plasma membranes. Plasma membranes are selectively-permeable and capable of controlling all movement of substances through:
passive transport, which does not use energy; and active transport which requires chemical energy in the form of ATP.Active transport involves the movement of substances out of cells against their gradients. For instance, glucose is transported across the membrane with specialized carrier proteins embedded within the membrane, and active transport; the cell's interior is highly concentrated- glucose is a high energy storage molecule required by many metabolic processes and required in high amounts.
The forms of active transport that should be in common is by using the ATP.
Forms of active transport:The plasma membrane should be selected also capable for controlling the movement of the substance via the passive transport where it does not use the energy and the active transport means when it needs the chemical energy in the form of ATP.
The interior of the cells should be highly concentrated glucose that shows an high energy storage molecule.

How does the ligand-gated channel for CFTR work?
Answers
Answer: Ligand-gated channels require a special “key” to unlock their doors, which usually comes in the form of a small molecule.
CFTR is a ligand-gated channel, but it’s an unusual one. Its “key” is ATP, a small molecule that plays a critical role in the storage and release of energy within cells in the body. In addition to binding the ATP, the CFTR channel must snip a phosphate group – one of three “P’s” – off the ATP molecule to function. But when, where and how often this crucial event takes place has remained obscure.

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..

How can a ‘FIXED’ cell be used to estimate the time spent in each phase of mitosis. Explain the process you used to determine the times for each phase.
Answers
Answer:
Calculate the percentage of time spent in each phase by counting the total number of cells in each phase (total in interphase, in prophase, etc.) ... Multiply the percentage of time in each phase by the total time of the cell cycle (720 minutes) and this gives you an estimate of the time spent in each phase.

A Paramecium has an internal sucrose concentration of 0.040 M, a glucose concentration of 0.035 M, and a fructose concentration of 0.0050 M. The Paramecium is placed in an aqueous solution that has solute concentrations of 0.025 M for sucrose, glucose, and fructose. Which solutes will diffuse out of the Paramecium?
a. Glucose and fructose
b.Sucrose and fructose
c.Sucrose and glucose
d. Sucrose, glucose, and fructose
Answers
Answer:
c. Sucrose and glucose
Explanation:
The paramecium is a large, single-celled microbes, surrounded by a plasma membrane. Simple diffusion occurs in cells across plasma membranes, as a form of passive transport. In diffusion, solutes move from regions of high concentration to regions of low concentration across the plasma membrane.
Here, the internal environment has higher concentrations of sucrose and glucose, but lower concentrations of fructose, thus the solutes will move along their concentration gradient, to where the concentrations are lower. In order for the fructose molecules to move out of the cell, the molecules have to move against their concentration gradient - a process requiring energy known as active transport.

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.
In the story, "Never Say Never," which character is dynamic?
Chelsea French
