Suppose that the atomic mass unit (amu) had been defined asone-sixth of the average mass of an atom of fluorine instead ofone-twelfth of the mass of an atom of carbon-12. What would theaverage atomic mass of phosphorus be on this new scale?

1. Average atomic mass of phosphorus on new scale = ?

What would the value of Avogadro's number be on this newscale?

2. New value for Avogadro's number = ?

Phosphorus has 23 known isotopes,only one of which is stable. Assume that phosphorus exists naturally as 97.02% p-31 and 2.98% p-30. Determine the average atomic mass of phosphorus, rounded to 2 decimals

How to resolve Avoid using private types in Public Apis

_MyApp createState() => _MyApp();

I try to fix it like this State<MyApp> createState() => MyAppState();
But then I hit another issue it will say create class 'MyAppState'.

How to fix the error message - 

The operator '<' can't be unconditionally invoked because the receiver can't be 'null' Try adding null check. Screenshot and  original code listed below. When I added null check if (invalue?.length! <10 ) did not resolve the issue.

Other than sex, what is the one trait in which the phenotypes of Aleph and Bizzy differ?

c)

d)

------------------------------

Other than sex, Aleph and Bizzy's puppies will all have the same phenotype, except for one possible variation. Which is it?

d)

-----------------------------------------

The breeder wanted to breed Gia with a dog who was an LL EE WW SS OO. What phenotype was the breeder trying to produce? Check all that apply:

a)

b)

c)

f)

----------------------------

While the breeder was trying to match Gia with the LLEEWWSSOO dog, she got out for a while. That's how she met Hero, a stray dog from the wrong side of town . . . When Gia's puppies were born, what surprises could there have been for the dog breeder? In other words, what possible phenotypes could have appeared in Gia's and Hero's puppies, which would have subverted the breeder's expectations?

g)

-------------------------------------------

The breeder tried to bring the phenotypes of Gia's puppies back in line with those of Aleph and Bizzy. To do so, he chose Jack to breed with Isis. When Isis gave birth to her pups, would the breeder have been pleased with how they looked?

The breeder wanted to breed Gia with a dog who was an LL EE WW SS OO. What phenotype was the breeder trying to produce? Check all that apply: Long leg Short legs Pointy ears Floppy ears Brown fur Black fur Brindle fur Social with humans Antisocial with humans Blue eyes Brown eyes Differently colored eyes

a) L is long-legged. l is short-legged. Long-legged is dominant, short legs are recessive. b) E is pointy ears. e is floppy ears. Pointy ears are dominant, floppy ears are recessive. c) W is brown fur, B is black fur. Brown and black are codominant. If W and B appear in the same dog, then that dog is "brindle" or striped. d) S is the allele for a dog who is social with non-dogs. s is the allele for a dog who is fearful of humans. e) O is brown eyes. U is blue eyes. O is dominant and U is recessive, EXCEPT when in females. Female dogs of the genotype OU have one blue and one brown eye.

Genotypes for selected dogs: Aleph = Ll Ee WW Ss OO Bizzy = LL EE WW SS OU

Aleph Bizzy
Caeser Druid Edda Fido Gia Hero
Isis Jack Killer Loo Marly
Nissa Olly Polly Quick Rani
Spot Tiny Ulysses Vera Whitey Yeller

Gia = LL EE WW SS OU

Hero = ll ee WB ss OU

Isis = LL EE WW Ss OO

Jack = Ll Ee WB Ss OO

Quick = LL EE WW Ss

What is the percentage chance that Killer will have differently colored eyes?

What are the chances that Nissa and Polly will have differently colored eyes?

Not counting Rani, in the first four generations of the pedigree, how many dogs have floppy ears?

The breeder killed Olly and Yeller, but not Nissa, Polly, Quick, Spot, Tiny, Ulysses, Very, nor Whitey. What can you say about Rani's genotype? (Clue: What is in Olly and Yeller's phenotype that would have been cause for the breeder to kill them?)

Why was breeding Isis and Jack an even bigger disaster than when Gia met Hero?

sickle-cell. If a heterozygote reproduces with a normal homozygote, what are the potential genotypes of their offspring?

How many pretti numbers are there?

Thanks to everyone answering my previous question. Decide to put the entire flutter widget program here. Using input from I got from the experts here. 

Major Issues found -

keyboardType: Flutter complains The named parameter keyboardType isn't defined.
How do I define it here?

if (inValue.length ==0) Flutter says use isempty
So I replaced like this if (inValue.isEmpty) but then Flutter shows the following
The property "isEmpty" can't be unconditionally accessed the because the receiver can be null
Try making the access conditional (using?.) or adding a null check to the target('!')

Also the onsave feature isn't working. There are others too many too list
