Where does the fertilized egg grow and develop while a woman is pregnant

Scilla [17]

Answer: Uterus

Explanation:

A fertilized egg is called ZYGOTE, and it is the product of fusion between a sperm cell and ovum cell.

The zygote is attached and housed in a muscular organ known as Uterus, commonly referred to as Womb. Here, the zygote grows and develops for several weeks into a foetus and then a human child (baby) in the pregnant woman

narvez 5. Everyone in Dobby's family has a long nose and they brag that they are from a purebred line. Viola has a stubby nose.

mote1985 [20]

Assuming a single diallelic gene coding for the trait and expressing complete dominance, the phenotypes, genotypes, and probabilities of getting each of them vary according to the parentals' genotypes. See the options below.

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

Since I do not have the genotypes from #2, I will provide different potential scenarios for this question.

I advise you to check on them and see which one matches the genotype from #2.

Let us assume a single diallelic gene is coding for the trait and expresses complete dominance.

<h3 /><h3>SCENARIO 1 ⇒ long nose is the dominant trait</h3>

Let us say that

L is the dominant allele and codes for long nose

l is the recessive allele and codes for stubby nose

Since long nose is dominant over stubby nose

LL and Ll ⇒ long nose

ll ⇒ stubby nose

If Dobby comes from a purebred family and has long nose, his genotype must be LL.

And if Viola has stubbi nose, her genotype must be ll.

Cross 1

Parentals) LL x ll

Gametes) L L l l

Punnett square) L L

l Ll Ll

F1) Genotype ⇒ 100% heter0zyg0us Ll

Phenotype ⇒ 100% long-nosed

There is 100% chances for a child to have a long nose

There is 0% chances for a child to have a stubby nose

These children are not purebred

**********

<h3>SCENARIO 2 ⇒ Stubby nose is the dominant trait</h3>

Let us say that

S is the dominant allele and codes for stubby nose

s is the recessive allele and codes for long nose

Since stubby nose is dominant over long nose

SS and Ss ⇒ stubby nose

ss ⇒ long nose

If Dobby comes from a purebred family and has long nose, his genotype must be ss.

And if Viola has stubbi nose, her genotype must be either SS or Ss.

There are two possible crosses.

Cross 1 : Violet is h0m0zyg0us dominant SS

Parentals) SS x ss

Gametes) S S s s

Punnett square) S S

s Ss Ss

F1) Genotype ⇒ 100% heter0zyg0us Ss

Phenotype ⇒ 100% stubby-nosed

There is 100% chances for a child to have a stubby nose

There is 0% chances for a child to have a long nose

These children are not purebred

Cross 2: Violet is heter0zyg0us, Ss

Parentals) Ss x ss

Gametes) S s s s

Punnett square) S s

s Ss ss

F1) Genotype ⇒ 50% heter0zyg0us Ss and 50% h0m0zyg0us recessive ss

Phenotype ⇒ 50% stubby-nosed and 50% long-nosed

There is 50% chances for a child to have a stubby nose

There is 50% chances for a child to have a long nose

These children are not purebred

With exercise during pregnancy, fetal hypoxia would be the result of

user100 [1]

It goes up consistently from 6-8 weeks gestation and to the highest point of maximum of ~150% pre-pregnancy level, around 32-34 weeks. Facilitates maternal/fetal exchange of: respiratory gases, nutrients, and metabolites, and reduces impact of maternal blood loss at delivery. 

- Red cell mass increases by 20-30%. Smaller than the ~50% increase in plasma volume. Net reduction in hemoglobin occurs.
