By definition, if the DNA of a cell undergoes a spontaneous mutation, is was NOT due to _________. Multiple Choice errors in DNA

Salsk061 [2.6K]

By definition, if the DNA of a cell undergoes a spontaneous mutation, is not due to exposure to radiation.

Spontaneous mutations are derived from various sources, which include mistakes made all through the replication of undamaged template DNA, mutagenic nucleotide substrates, and endogenous DNA lesions.

Spontaneous mutation, also referred to as background mutation can be defined as genetic modifications that arise inside the absence of mutagens and haven't any recognized reason.

It is able to result from sports of a normal cellular, including mistakes or errors during DNA replication.

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

Are gender traits completely a result of societal expectations?

musickatia [10]

$\huge\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}\star$

No. Gender traits in humans are largely determined by biophysical processes. There seems to be a vocal political faction that is trying to convince people in the name of liberty and equality that gender traits are completely learned, and therefore arbitrary.

But this claim disagrees with scientific evidence. In general, boys play more with cars and girls play more with dolls not because their parents are perpetuating outdated gender stereotypes, but because their brain is telling them to.

This fact does not mean that boys have to play with boy toys, or that boys who play with dolls aren't really boys. It is just a scientific observation about average behavior and its link to fetal development

A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypoton

Tcecarenko [31]

Answer:

True

Explanation:

This process is called Chemiosmotic Theory.

Two different solutions with a semi-permeable barrier (it allows to pass throw just water or solute, not both) will try to get into equilibrium.

Then, if you allows to pass just water though the barrier, it will go from the solution with less solute to the solution with more solute, in order to reach the solution equilibrium.
