An opportunistic predator switches prey, capturing whichever prey species is most abundant. As soon as the prey numbers dwindle and another species becomes more abundant, the predator will consume the more abundant species. In doing so, this predator maintains great biodiversity in the community. This type of predator is called a

Answer:
The correct answer is keystone predator.
Explanation:
In sustaining the composition of an ecological community, a keystone species plays an essential function. In the absence of keystone species, the ecosystem would fail to exist and would become drastically different. A predator is a classic illustration of a predator, which inhibits a specific herbivorous species from eradicating the dominant species of plants. In the non-existence of predators, the herbivorous prey would increase enormously and would clean the entire essential plant species, and thus, drastically change the significance of the ecosystem.

Explanation:
Fluorescent FM dyes partition reversibly into biological membranes without penetrating through them. Suppose that you have neurons cultured in a dish, and you incubate them with an FM dye for a period of time before washing the cells with excess medium to remove the dye.a)You find that if you stimulate the neurons to trigger action potentials during incubation with the dye, the synaptic regions of the neurons remain fluorescent after the wash. Propose an explanation for this effect.b)After you have generated fluorescent synaptic regions by this procedure, suppose that you trigger further action potentials while continuing to wash with excess medium. Would you expect the synaptic regions to lose fluorescence
Answers
Answer:
a) Emission observed is due to emission of synaptic vessels
b) Yes
Explanation:
a) Proposing an explanation
The emission observed ( the synaptic regions of the neurons remaining fluorescent ) is due to the emission on the synaptic vessels given that FM dyes have lipid-sensitive emission which can be loaded into a recycled synaptic vesicle
b)
The synaptic regions will lose fluorescence when you continue to wash with excess medium, also the more action potentials triggered the more observed emission. hence the increase in the loss of fluorescence is due to the fact that the emissions are not permanent

La teoría sintética
El redescubrimiento en 1900 de la teoría de la herencia de Mendel por el botánico y genetista holandés Hugo de Vries y otros llevó a un énfasis en el papel de la herencia en la evolución. De Vries propuso una nueva teoría de la evolución conocida como mutacionismo, que esencialmente eliminó la selección natural como un proceso evolutivo importante. Según de Vries (a quien se unieron otros genetistas como William Bateson en Inglaterra), en los organismos tienen lugar dos tipos de variación. Una es la variabilidad "ordinaria" observada entre los individuos de una especie, que no tiene consecuencias duraderas en la evolución porque, según de Vries, no podría "conducir a una transgresión de la frontera de la especie [es decir, al establecimiento de nuevas especies] incluso en las condiciones de la selección más rigurosa y continua ". El otro consiste en los cambios provocados por mutaciones, alteraciones espontáneas de genes que dan lugar a grandes modificaciones del organismo y dan lugar a nuevas especies: “La nueva especie se origina así de repente; es producido por el existente sin ninguna preparación visible y sin transición ”.
Muchos naturalistas se opusieron al mutacionismo y, en particular, los llamados biometristas, liderados por el estadístico inglés Karl Pearson, quien defendió la selección natural darwiniana como la principal causa de la evolución a través de los efectos acumulativos de variaciones individuales pequeñas y continuas (que los biometristas se supone que pasa de una generación a la siguiente sin estar limitado por las leyes de herencia de Mendel).

5 The systolic blood pressure reading of 140-159 the systolic blood pressure reading of 140 - 159 is what stage of Hypertension?
A Stage 2
B Stage 1
C Stage 3
D High Normal
Answers
Answer:
B. Stage 1
Explanation:
Systolic blood pressure is less than 120 mm Hg and Diastolic less than 80 mm Hg so it is considered as normal. Pre-Hypertension occurs when the Systolic blood pressure is 120 - 139 and Diastolic pressure is 80 - 89. Stage 1 Hypertension is considered when the Systolic blood pressure is 140 - 159 and Diastolic blood pressure is 90- 99. If the Systolic blood pressure is greater than 160 it is considered as Stage 2 Hypertension.
There are marked differences in the type of organisms found at four different locations at the same tidal height along ta rocky shore. What might account for this
Answers
Answer and Explanation:
Many elements can be responsible for this, among them, we can mention the presence and absence of predators in the different places on the rocky coast. This is because predators can influence not only the number of organisms found, but also the types of organisms.
Another element that may be the cause of this variability is the availability of resources necessary for the life of these organisms, in addition, the impact of the waves on the rocks, can cause the variability of the organisms, since some may not be able to resist the impact of the waves.

how scientists are able to determine climate information by just looking at tree rings? (how does it work?)
Answers
Explanation:
Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that area's local climate in the past. For example, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry.
Answer:
Explanation:
Climate scientists compare the tree growth records to local weather records. For locations where a good statistical match exists between tree growth and temperature or precipitation during the period of overlap, the ring widths can be used to estimate past temperature or precipitation over the lifetime of the tree.

What are the applications of CRISPR/Cas9-mediated Epigenetic Editing?
The CRISPR/Cas9 with the advantages of low cost and ease of use gives researchers the opportunity to manipulate the epigenome and observe its possible effects on cell function, development, and differentiation (Figure 1). Using non-active dCas9 (another type of Cas9 lacking nuclease activity but retaining DNA binding activity) fused enzymes such as DNA methylase, histone acetyltransferase, and deacetylase can be targeted to alter the epigenetic state of precise locations within the genome.
https://www.creative-biogene.com/crispr-cas9/solution/crispr-cas9-mediated-epigenetic-editing.html
Answers
Answer:
Applications:
- silence gene expression of target genes
- activate gene expression of target genes
- determine the role of DNA methylation and histone modifications (methylation, acetylation, etc) on specific regulatory sites (e.g., enhancer sequences)
Explanation:
The CRISPR/Cas9 system can be repurposed to edit the epigenome of living cells. For this purpose, it is required 1-to fuse a catalytically inactive 'dead' Cas9 enzyme with enzymes involved in epigenetic mechanisms (e.g., DNA methyltransferases, histone deacetylases, etc) capable of activating or deactivating gene expression, and 2-to design single-guide RNAs (sgRNAs) complementary to the sequence of interest (i.e., target sequences whose epigenome landscape we are trying to modify). For example, dCas9 gene has been fused with the DNA methyltransferase 3a (Dnmt3a) gene to create a dCas9-DNMT3A complex which can be combined with a specific sgRNA in order to study the effects of DNA methylation at a particular gene. These CRISPR/Cas9-mediated epigenome editing systems have shown to be very useful to understand how epigenome drives chromatin folding and dynamics at specific genomic sites (loci), and thus regulate gene expression at the transcriptional level.

A polygraph test is conducted, and the findings indicate that there is an 80 percent chance of deception. What does this mean for the investigation?
The suspect is guilty and should be arrested for the crime.
The suspect is probably just nervous since 80 percent is a pretty high number and usually indicates a false positive.
The suspect might be guilty, but more information is needed from other parts of the investigation.
There has been a mistake in the polygraph test, and the test should be conducted again to get better results.
Answers
Answer:
The suspect might be guilty, but more information is needed from other parts of the investigation.
Explanation:
Due process states innocent until proven guilty. Having an 80 percent chance of deception is not solid proof of anything. It does, however, bring more speculation to the table that this person is indeed guilty, but because there is no actual proof, the investigators must find more information on the matter.
