Answer:

Vacunas

Explanation:

Las vacuna son preparaciones seguras obtenidas mediante numerosos ensayos clínicos, cuyo objetivo es generar inmunidad contra una enfermedad mediante la producción de anticuerpos. Basicamente, existen tres tipos de vacunas: vacunas atenuadas, vacunas de ARN mensajero y vacunas de terapia genética. En primer lugar, las vacunas atenuadas están desarrolladas usando fragmentos del virus que provoca la enfermedad, lo cual se conoce como vacunas atenuadas porque están fabricadas con virus atenuados/inactivados. Por otra parte, en los últimos años, han sido desarrolladas vacunas derivadas de ARN mensajeros (ARNm) las cuales permiten sintetizar una proteína específica del virus (antígeno) y de este modo generar una respuesta inmune que permanecerá ante una posible infección. Finalmente, las vacunas de terapia génica utilizan como vector un virus que no se integra al genoma pero que es altamente estable, como por ejemplo un adenovirus (un virus del resfriado común), el cual permite introducir en las células la información genética del patógeno a fin de generar proteínas virales específicas capaces de desencadenar una respuesta inmune, es decir, generar anticuerpos específicos, contra el virus.

Answer:

determined

Explanation:

Determined cells are embryonic cells that will generate all the cell types of the adult organism, with this process being independent of environmental inputs. Cell determination is defined by specific gene expression patterns in embryonic cells. In consequence, cell determination is defined as a genetic process where a particular cell fate can be broken down into two different states: specified (committed) or determined. If a cell is in a committed/specified state, the cell's fate can still be reversed or transformed, while if a cell in a determined state, the cell's fate cannot be reversed or transformed.

In addition to providing a structural support for the body and a reservoir for calcium, bone encases the bone marrow, a primary site for hematopoiesis and immune system development.

Explanation:

DNA is the genetic material contained in the cells of living organisms. The DNA contains a segment called GENE, which contains information used to produce useful products needed in the cell. The information contained in the gene is expressed to produce PROTEINS.

PROTEINS are responsible for many metabolic activities that occurs in a cell. The CELL functions due to activities of the proteins produced by gene expression. When similar cells come together, they form TISSUES. An aggregation of tissues performing similar functions form ORGAN. Organs functioning similarly come together to form ORGAN SYSTEM. A collection of organ systems in the body forms the ORGANISM.

Answer:

Collapse dolines.

Explanation:

A doline is a special type of geological depression characteristic of karst reliefs. These reliefs are formed by the chemical weathering of rocks made of minerals that are soluble in water. In general, dolines are found in places where rocks are composed of limestone and clay in different proportions. When the calcium carbonate of limestone gets in contact with the rainwater, turns into calcium bicarbonate, which is soluble in the presence of water. Clay then deposits in lower areas originating the dolines or depressions.

Dolines might be formed by dissolution (the soil is dissolved in pluvial water that first flood and then infiltrate) or by collapsing. Collapse dolines occur because first, soluble material in lower layers formes a cavity underground. Soluble material flow to lower areas making a place to a cavity or hole under the ground. It gets bigger with time as the material in the bottom keeps being removed. It reaches a point in which the cave can no longer support the roof material, such as rocks, soil, and vegetables, and ends collapsing.  

Answer:

Primary succession occurs in an area with no life and no soil but secondary succession happens in an area where an existing community was disrupted.

Explanation:

Ecological succession, which is the series of changes that occurs in an ecosystem over a period of time, can be divided into two types namely: primary succession and secondary succession.

- Primary succession is a kind of succession in which a bare surface or rock is colonized by certain organisms called PIONEERS. Primary succession occurs in an area with no life and no previous soil.

- On the contrary, secondary succession occurs in an area that has been previously colonized but disturbed as a result of natural occurrences e.g earthquake, wildfire, flooding etc.

Answer:

Explanation:

A prokaryotic cell is a type of cell that does not have a true nucleus or membrane-bound organelles. Organisms within the domains Bacteria and Archaea are based on the prokaryotic cell, while all other forms of life are eukaryotic

A prokaryotic is a primitive cell that lacks organelles, unlike the eukaryotic cells, and are simple organisms.

Prokaryotes are organisms that are simple and evolved before the complex eukaryote. They include bacteria and archaea that are simple and lack organelles that are found in eukaryotes.

They do not have a nucleus and rather have their genetic material disposed of as nucleoids in the center of the cell that undergoes the simple process of the central dogma.

The simple cellular processes and reproductive methods are the reason they lack many organelles. This tells that prokaryotes are simple and primitive types of cells.

Therefore, prokaryotes lack a distinct nucleus.

Explanation:

Answer:

is number three

Explanation:

Answer:

- Accuracy is the degree by which the measures obtained in an experiment and/or observational procedure are associated with true values.

- Precision is the level of reproducibility that these measurements exhibit in the same (constant) conditions.

- Reproducibility indicates the level of agreement of the results when they are obtained by different researchers by applying the same experimental and/or observational procedures.

Explanation:

In a scientific investigation, it is imperative to achieve higher levels of accuracy and precision when realizing measurements because it ensures that the information is correct (without mistakes). Thus, researchers always try to use better equipment and instrument to make their measurements. Reproducibility is important because it is the only condition that scientists can guarantee to other researchers when they arrive at a result.

Answer:

Behavioral isolation is demonstrated in species of finches. Their mating calls are distinct yet unique across species.

Explanation:

Mutations arising from errors within gene replication often accumulate within populations, becoming more stable. They may lead to the formation of separate, genetically distinct populations called species. These new species arise via:

Behavioral isolation is an isolating mechanism that is part of sympatric speciation. Here, there are apparent non-physical barriers to prevent mating, and several related species live within a population and gene-flow.  However, reproductive isolation occurs through assortative mating (mate choice based on shared traits) which may lead to heteropatric speciation.

Commonly observed in birds, it involves distinct and unique courtship and mating signals. Mates only respond to those fitting the required behavioral patterns such as a courtship dance, nest building, foraging and songs.

Explanation:

Answer:

D.) repressor DNA-binding site mutation

Explanation:

lacl prevents the repressor polypeptide is a mutant that prevent operon from binding lactose, and thus will bind to the operator and be non-inducible.. This mutant will represses the lac operon whether lactose is present or not and the lac operon will not be expressed. It is also called“super-supperesor".

The lacI locus – One type of mutant allele of lacI (callled I-) prevents the production of a repressor polypeptide or produces a polypeptide that will not allow to bind to the operator sequence.

This is also a constitutive expresser of the lac operon because absence of repressor binding permits transcription.
