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.

Answers

Answer:

The correct answer is - closely related species.

Explanation:

If two species have similar gene sequences or nucleotide sequences with the same base pairs then it means they both are closely related and have diverged from a similar and latest ancestor.

The same gene sequence results in the same proteins that could result in the same phenotypic behavior. Such cases establish that both species are closely related and have recently diverged. These species must have a common ancestor.

Answers

Answer:

Por difusión.

Explicación:

Los organismos simples como las bacterias, los protozoos, las algas y los hongos no tienen un sistema de excreción especializado. Hicieron la excreción a través del proceso de difusión en el que los materiales se mueven de la región de alta concentración a la región de menor concentración. Debido a esta difusión, hay una gran cantidad de material de agua presente, por lo que el material de desecho se mueve desde el interior del cuerpo al entorno exterior a través de la membrana presente alrededor de su cuerpo y este proceso de difusión también se utiliza para la absorción de nutrientes.

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

In which way are glaciers and rivers similar?
A. Both are made of solid water.
B. Both have quickly flowing water.
C. Both transport and deposit material.
D. Both can move large boulders hundreds of miles.

Answers

Answer:

c

Explanation:

they both deposit and transport material.

The way by which glaciers and rivers similar are both have quickly flowing water. Thus, option B is correct.

Both glaciers and rivers are natural water systems that play a significant role in the movement and transportation of materials. While glaciers are large masses of ice that flow slowly over land, rivers are bodies of flowing water.

Glaciers and rivers both transport materials from one location to another. Glaciers carry rock debris, soil, and sediment within their icy mass as they move downhill, while rivers carry sediments such as sand, silt, and rocks downstream.

Both glaciers and rivers have the ability to erode the land and transport the eroded materials. Glaciers can scrape and pluck rocks and sediments as they move, causing erosion of the underlying landscape. Similarly, rivers erode the bed and banks of their channels, carrying away loose materials in the process.

Therefore, the correct answer is C. Both glaciers and rivers transport and deposit material.

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).
