What is the main difference between sexual and asexual reproduction

Chemistry

Answer:

Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information.

A 6.000L tank at 19.2°C is filled with 18.0g of carbon monoxide gas and 10.6g of chlorine pentafluoride gas. You can assume both
Jobisdone [24]

Answer:

Total pressure: 2.89 atm

Mole fraction CO: 0.88

Partial pressure CO: 2.56 atm

Mole fraction ClF₅: 0.12

Partial pressure ClF₅: 0.33 atm

Explanation:

We should apply the Ideal Gases Law to solve this:

P . V = n . R . T

We need n, which is the total moles for the mixture

Total moles = Moles of CO + Moles of ClF₅

Moles of CO = mass of CO / molar mass CO → 18 g/28 g/mol = 0.643 mol

Moles of ClF₅ = mass of ClF₅ / molar mass ClF₅ → 10.6g/ 130.45 g/m = 0.0812 mol

0.643 mol + 0.0812 mol → 0.724 moles in the mixture

So we have the total moles so with the formula we would know the total pressure.

P . 6L = 0.724 mol . 0.082L.atm/mol.K . 292.2K

P = ( 0.724 mol . 0.082L.atm/mol.K . 292.2K) / 6L

P = 2.89 atm

Mole fraction is defined as the quotient between the moles of gas over total moles, and it is equal to partial pressure of that gas over total pressure

Moles of gas X /Total moles = Partial pressure of gas X/Total pressure

(Moles of gas X / Total moles) . Total pressure = Partial pressure of gas X

Mole fraction CO = 0.643 / 0.724 = 0.88

Partial pressure CO = 0.88 . 2.89 atm → 2.56 atm

Mole fraction ClF₅ = 0.0812 / 0.724 = 0.12

Partial pressure ClF₅ = 0.12 . 2.89 atm → 0.33 atm

A balloon vendor at a street fair is using a tank of helium to fill her balloons. The tank has a volume of 124.0 L and a pressur
amm1812

Answer:

She lost 50.88 moles

Explanation:

Step 1: Data given

The volume of the tank = 124.0 L

The initial pressure = 104.0 atm

The temperature = 24.0 °C = 297 K

The pressure drops to 94.0 atm

The temperature stays constant at 297 K

Step 2: Calculate the initial number of moles

p*V = n*R*T

n = (p*V)/(R*T)

⇒with p = the initial pressure = 104.0 atm

⇒with V = the initial volume = 124.0 L

⇒with n = the initial number of moles = TO BE DETERMINED

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒ with T = the temperature= 297 K

n = (104.0*124.0)/(0.08206*297)

n = 529.14 moles

Step 3: Calculate final number of moles

p*V = n*R*T

n = (p*V)/(R*T)

⇒with p = the initial pressure = 94.0 atm

⇒with V = the initial volume = 124.0 L

⇒with n = the initial number of moles = TO BE DETERMINED

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒ with T = the temperature= 297 K

n = (94.0*124.0)/(0.08206*297)

n = 478.26 moles

Step 4: Calculate the difference of moles

529.14 moles - 478.26 moles = 50.88 moles

She lost 50.88 moles

Scientists saw how well people responded to animals and imagined ___________ that these interactions might be helpful in some ty
sukhopar [10]

For most of the last 50 years, technology knew its place. We all spent a lot of time with technology—we drove to work, flew on airplanes, used telephones and computers, and cooked with microwaves. But even five years ago, technology seemed external, a servant. These days, what’s so striking is not only technology’s ubiquity but also its intimacy.

On the Internet, people create imaginary identities in virtual worlds and spend hours playing out parallel lives. Children bond with artificial pets that ask for their care and affection. A new generation contemplates a life of wearable computing, finding it natural to think of their eyeglasses as screen monitors, their bodies as elements of cyborg selves. Filmmakers reflect our anxieties about these developments, present and imminent. In Wim Wenders’s Until the End of the World, human beings become addicted to a technology that shows video images of their dreams. In The Matrix, the Wachowski brothers paint a future in which people are plugged into a virtual reality game. In Steven Spielberg’s AI: Artificial Intelligence, a woman struggles with her feelings for David, a robot child who has been programmed to love her.

Today, we are not yet faced with humanoid robots that demand our affection or with parallel universes as developed as the Matrix. Yet we’re increasingly preoccupied with the virtual realities we now experience. People in chat rooms blur the boundaries between their on-line and off-line lives, and there is every indication that the future will include robots that seem to express feelings and moods. What will it mean to people when their primary daily companion is a robotic dog? Or to a hospital patient when her health care attendant is built in the form of a robot nurse? Both as consumers and as businesspeople, we need to take a closer look at the psychological effects of the technologies we’re using today and of the innovations just around the corner.

Indeed, the smartest people in the field of technology are already doing just that. MIT and Cal Tech, providers of much of the intellectual capital for today’s high-tech business, have been turning to research that examines what technology does to us as well as what it does for us. To probe these questions further, HBR senior editor Diane L. Coutu met with Sherry Turkle, the Abby Rockefeller Mauzé Professor in the Program in Science, Technology, and Society at MIT. Turkle is widely considered one of the most distinguished scholars in the area of how technology influences human identity.

Few people are as well qualified as Turkle to understand what happens when mind meets machine. Trained as a sociologist and psychologist, she has spent more than 20 years closely observing how people interact with and relate to computers and other high-tech products. The author of two groundbreaking books on people’s relationship to computers—The Second Self: Computers and the Human Spirit and Life on the Screen: Identity in the Age of the Internet—Turkle is currently working on the third book, with the working title Intimate Machines, in what she calls her “computational trilogy.” At her home in Boston, she spoke with Coutu about the psychological dynamics between people and technology in an age when technology is increasingly redefining what it means to be human.

You’re at the frontier of research being done on computers and their effects on society. What has changed in the past few decades?

To be in computing in 1980, you had to be a computer scientist. But if you’re an architect now, you’re in computing. Physicians are in computing. Businesspeople are certainly in computing. In a way, we’re all in computing; that’s just inevitable. And this means that the power of the computer—with its gifts of simulation and visualization—to change our habits of thought extends across the culture.
