One parent has type A blood and the other has type B. What are their genotypes if they produced children whose blood types were all type AB?
Answers
Answer:
iAiA and iBiB
Explanation:
Blood type in humans is controlled by a gene with three alleles namely: iA, iB, and i. Alleles iA and iB are dominant over allele 'i' but codominant. The following are the allelic combinations of the genotype and the resulting blood types:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, one parent has type A blood and the other has type B. If all the offsprings of these parents have blood type AB, this means that the parents must have a genotype of iAiA and iBiB respectively.

Which RNA base pairs with the adenine in DNA?
Othymine

Adenine in DNA pairs with uracil in RNA. Therefore option “D” is correct.
What is nucleotide base pairing?There are five types of the nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases. Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purines.
DNA consists of adenine, cytosine, guanine, and thymidine. In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil.
Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.
Nucleotide base pairing is important for the stability of the DNA.

A geneticist found that a particular mutation had no effect on the polypeptide encoded by a gene. This mutation probably involved __________. View Available Hint(s) A geneticist found that a particular mutation had no effect on the polypeptide encoded by a gene. This mutation probably involved __________. insertion of one nucleotide substitution of one nucleotide alteration of the start codon deletion of one nucleotide
Answers
Answer:
The answer is "Substitution of one nucleotide ".
Explanation:
Replacement mutant is a kind of DNA replication mistake placing faulty nucleotide or nucleotide sequences in the wrong positions. A nucleotide sequence substitutes for just a type of substitution mutant, a spots gene.
A researcher observed that a specific mutation did not affect a gene-encoded polypeptide. This mutation was presumably the replacement of the nucleotide.

Explanation:
what changes were most likely caused by a shift in earth's continents?
Answers
Answer:
The earth’s crust is broken into separate pieces called tectonic plates (Fig. 7.14). Recall that the crust is the solid, rocky, outer shell of the planet. It is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. Both types of crust rest atop solid, upper mantle material. The upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.
Each tectonic plate is free-floating and can move independently. Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. The term fault is used to describe the boundary between tectonic plates. Most of the earthquakes and volcanoes around the Pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. Other observable results of short-term plate movement include the gradual widening of the Great Rift lakes in eastern Africa and the rising of the Himalayan Mountain range. The motion of plates can be described in four general patterns:
<p><strong>Fig 7.15.</strong> Diagram of the motion of plates</p>
Collision: when two continental plates are shoved together
Subduction: when one plate plunges beneath another (Fig. 7.15)
Spreading: when two plates are pushed apart (Fig. 7.15)
Transform faulting: when two plates slide past each othe

Las plantas transforman la luz del sol a través de unas células llamadas: a) Estomas. b) Cloroplastos. c) Raíces. d)Clorofila.
Answers
Respuesta:
La respuesta correcta es: b) Cloroplastos.
Explicación:
Los cloroplastos son organelas que se encuentran en las células vegetales y son responsables de realizar el proceso clave para la supervivencia de estos seres vivos: la fotosíntesis.
La fotosíntesis consiste en la transformación de sustancias inorgánicas a materia orgánica gracias a la energía proveniente de la luz solar. Esta materia orgánica será utilizada para la producción de los nutrientes requeridos por las células de la planta.
Los cloroplastos constan de una envoltura conformada por dos membranas y por unas vesículas llamadas tilacoides donde se encuentran las moléculas que participan en la transformación de energía lumínica a energía química que ocurre durante la fotosíntesis, por ejemplo la clorofila (que es un pigmento verde que le da a la planta su característico color).
