An anthropologist finds bone that her instruments measure it as 0.717% of the amount of carbon-14 the bones would have contained when the person was alive. How long ago did the person die? The half life of carbon 14 is 5,730 years. Round your answer to the nearest thousand . ****PLEASE HELP****

The relationship for radioactive decay is given by:

N(t) = N₀ * exp(-kt), where k is the decay constant.

We may substitute k using the equation:
k = 0.693 / t₀.₅, where t₀.₅ is the half life of the substance

The equation becomes:

N(t) = N₀ * exp(-0.693t / t₀.₅)

The ratio of N(t) : N₀ is 0.717%, or 0.00717. Using this

0.00717 = exp(-0.693t / 5,730)

0.693t = 28,294
t = 40,828.3

The person was alive almost 41,000 years ago.

Somebody once told me the world is gonna roll me
I ain’t the sharpest tool in the shed
She was looking kind of dumb with her finger and her thumb
In the shape of an “L” on her forehead

Well the years start coming and they don’t stop coming
Fed to the rules and I hit the ground running
Didn’t make sense not to live for fun
Your brain gets smart but your head gets dumb
So much to do, so much to see
So what’s wrong with taking the back streets?
You’ll never know if you don’t go
You’ll never shine if you don’t glow

Hey now, you’re an all-star, get your game on, go play
Hey now, you’re a rock star, get the show on, get paid
And all that glitters is gold
Only shooting stars break the mold

It’s a cool place and they say it gets colder
You’re bundled up now, wait till you get older
But the meteor men beg to differ
Judging by the hole in the satellite picture
The ice we skate is getting pretty thin
The water’s getting warm so you might as well swim
My world’s on fire, how about yours?
That’s the way I like it and I never get bored

Hey now, you’re an all-star, get your game on, go play
Hey now, you’re a rock star, get the show on, get paid
All that glitters is gold
Only shooting stars break the mold

Hey now, you’re an all-star, get your game on, go play
Hey now, you’re a rock star, get the show, on get paid
And all that glitters is gold
Only shooting stars

Somebody once asked could I spare some change for gas?
I need to get myself away from this place
I said yep what a concept
I could use a little fuel myself
And we could all use a little change

Well, the years start coming and they don’t stop coming
Fed to the rules and I hit the ground running
Didn’t make sense not to live for fun
Your brain gets smart but your head gets dumb
So much to do, so much to see
So what’s wrong with taking the back streets?
You’ll never know if you don’t go (go!)
You’ll never shine if you don’t glow

Hey now, you’re an all-star, get your game on, go play
Hey now, you’re a rock star, get the show on, get paid
And all that glitters is gold
Only shooting stars break the mold

And all that glitters is gold

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

If we make life better for ourselves, we can do the same thing, in a larger extent, to help others. 

we, as human beings, have created the pollution that exists on earth. technology also creates this pollution. as technology increases and helps people lead easier/better lives, the old technology is abandoned. look at the data for LCD screens as trash, the lead that a CRT can produce in the environment, the circuitry that is strewn throughout the dumps of the world, if they make it to the dumps, the chemical waste produced just in making more of the tecnologically better devices. 

look at recycling numbers across the country. in my town in a north eastern coastal state, recycling is very well received and can make a difference. i know people in the midwest where recycling is not even an option. recycling will only work if everyone does it. it can’t work if only a few people do it based on cost/benefit numbers. 

so, if people want to do better for everyone, they have to start with themselves and then move on to others. to paraphrase, to act globally, people need to start locally

False. The allele conferring the black colour to the coat won’t destroy the other copy of the gene conferring the brown copy as in heterozygous there is an allele (in this case, the one conferring the black colour) that is dominant over the other. This means that the earlier will not destroy the latter, but will, instead, overrun it making its genetic information prevail over the recessive allele’s genetic information (brown).

Answer;

D. Its body cells would have 40 chromosomes, and its gametes would have 20 chromosomes

Explanation;

-A diploid number of chromosomes means that a cell has two sets of chromosomes in their nucleus, while haploid number of chromosomes means that the cells have only one set of chromosome pairs.

-Somatic cells or body cells divide by mitosis, which means the diploid number of chromosomes is always retained, as the daughter cells are similar to the parent cells. In gametes cells on the other hand, they are haploid since they result from the process of meiosis which halves the number of chromosomes.

-Therefore, in this case,the body cells would have 40 chromosomes, which is the diploid number, and its gametes would have 20 chromosomes, the haploid number.
