What is an example of behavioral isolation
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:
allopatric speciationperipatric speciationparapatric speciationand sympatric speciationBehavioral 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.
Which types of mutations in the lac operon stop Escherichia coli from utilizing lactose as a carbon source? a) promoter deletion b) lactose-binding site mutation c) repressor DNA-binding site mutation d) operator deletion
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.

what is accuracy, precision, and reproducibility ? and why are they so necessary in conducting/designing experiments
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.

A structure that looks the same and does the same job but was not present in a common ancestor is termed:______.
Answer:
The correct answer is - analogous.
Explanation:
Analogous structures or organs are the structures with the same look which is developed to perform the same job and not present because inherited by a common ancestor.
These structures are present in unrelated organisms and look the same from outside and perform the same action for example wings of bat and birds look and perform the same action but not inherited from a common ancestor.

Draw a flow chart that explains how DNA is used to create an organism. please use the words: DNA, gene, protein, cell, tissue, organ, organism.
Answer:
Please find the flowchart attached as an image
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.

An mRNA cap will be found on ____________.
a. the primary transcript
b. the mRNA
c. at least one of the lariats
d. the poly(A) tail.
e. exon 1
f. all exons
g. some introns
Answer:
a. the primary transcript
Explanation:
The first step in RNAm maturation is the modification of the 5' end of the transcript via the addition of a structure called a cap or 7-methyl guanosine cap. The enzymes responsible for the formation of this cap are recruited to the phosphorylated C-terminal domain after the addition of the first twenty to thirty nucleotides of ARN. The formation of the cap is started by the addition of a GTP molecule oriented inversely to the 5' end nucleotide on RNA. Then methyl groups are added to this G residue and to the ribose forms of one or two nucleotides located on the 5' end. All these reactions take place in the nucleus when the mRNA is found as a primary transcript.
Describe what happens in the ocean with plate tectonics
Answer:
As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. ... This rock (basalt) becomes a new part of Earth's crust. Mid-Ocean Ridges. Seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor.
Formed when caves can no longer support the dirt above it.
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.
Why do you think prokaryotic cells do not have all the organelles that eukaryotic cells do? What does this tell you about prokaryotic cells?
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.
What are prokaryotes?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.

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.
