The question lacks essential part that is options to answer, however the options are given:
1. Birds have shorter lifespans, making generations shorter.
2. The bird population is likely much greater, allowing for more data.
3. Tortoises move too slowly for natural selection to influence shell phenotype.
4. Birds are easier to track and monitor.
Answer:
The correct options are : 1, 2, and 4.
Explanation:
For the accuracy and dependability of any experiment, various observations must be as extensive as possible. It decreases the impact of any observation or any event which may have occurred by some coincidence or mistake.
Therefore, finches were smarter to record observation as they were accessible in enormous numbers when compared with the turtle.
Likewise, the life cycle of birds is less when contrasted with the turtle which empowered the researchers to observe more generations.
In conclusion, the birds were anything but difficult to catch and track when contrasted with the turtle. Turtle is a land and water proficient which made it hard to follow them.

crees que la esclavitud atenta contra la diversidad cultural y el multiculturalismo
Answer:
Sí, creo que la esclavitud amenaza la diversidad cultural y el multiculturalismo porque la esclavitud proviene de la opresión y la pérdida de la identidad. También implica verse obligado a abrazar otras ideologías mientras relega a un segundo plano las propias creencias personales, lo que resulta en una falta de multiculturalismo.
Explanation:
La esclavitud es la inhumanidad del hombre hacia el hombre. Despoja al esclavo de su sentido de existencia y sistema de creencias. Esta opresión, que a menudo es física, mental y psicológica, hace que el individuo pierda autoestima e identidad. En un entorno que debería promover la diversidad cultural cuando conviven personas de diversas razas y culturas, existe una conformación a una forma de vida que dificulta el desarrollo del multiculturalismo. Aunque esto puede ser resistido inicialmente, las horas extra de estos descendientes pierden su identidad.

What happens after the mRNA transcript is formed in the nucleus to mark its destination
Early scientists were conflicted about the mechanism by which cells were created, with some scientists holding the viewpoint that cells were spontaneously crystallized in what was known as free cell formation. Robert Remak discovered ways to fix and observe cell membranes in various stages of cell division. These findings led Rudolf Virchow to proclaim in 1855, Omnis cellula e cellula (every cell comes from another cell), thus completing the tenets of cell theory.
Answer: All cells come from preexisting cells.
Explanation:
The given paragraph is about cells develop from the preexisting cells. The doubling of the genetic material in the S-phase is the triggering mechanism for cell division. In the process of mitosis the genetic material get reduced. The daughter cells vary by the amount of genetic material they receive. This proves that the new cells form from the pre-existing cells.

What is the term used to describe the build-up of a higher concentration of H+ on one side of the inner membrane of the mitochondrion than on the other side during the electron transport chain?
Answer:
electrochemical proton gradient
Explanation:
The electrochemical proton gradient is defined as the difference in the proton concentration or hydrogen ions (H+) concentration across a inner mitochondrial membrane during the electron transport chain.
The electrochemical proton gradient is build due to the active transport of ions across the cell membrane which is useful for ATP synthesis during the electron transport chain by the coupling of the electrochemical gradient across the membrane.
Hence, the term used is electrochemical proton gradient.

To determine whether regulation of gene expression by short RNAs was a naturally occurring phenomenon, researchers isolated RNA from a cell and fractionated them by size to obtain only short RNAs. The next step was to clone these molecules.
Today the cloning step would not be required. Which of the techniques below is the best reason why?
A. Because a microarray could tell if the fragments were encoded by the genome.
B. Because a PCR reaction could tell if the fragments were encoded by the genome.
C. Because an RNA-seq reaction could tell if the fragments were encoded by the genome.
D. Because a yeast 2 hybrid could tell if the fragments were encoded by the genome.
E. Because a GFP fusion could tell if the fragments were encoded by the genome.
Answer:
C. Because an RNA-seq reaction could tell if the fragments were encoded by the genome.
Explanation:
The combination of single-cell RNA sequencing (RNA-Seq) and bioinformatic tools to assemble and annotate sequence reads is currently the most common methodology used to obtain complete transcriptomes from individual cells. RNA-seq is a Next-Generation Sequencing (NGS) technology that enables the analysis of the entire transcriptome, thereby this method can be used to examine gene, allelic and ncRNA expression. In the last years, RNA-seq has become the gold standard technique for direct analysis of ncRNA expression profiles in biological samples and clinical research.
Research findings suggest that symptoms of schizophrenia are more likely to be present when the individual has a genetic predisposition to schizophrenia and also experiences a stressful environmental event. These findings are consistent with a model of _______________________. Group of answer choices probandwise concordance gene-environment interaction reactive genotype-environment correlation active genotype-environment correlation
Answer: gene-environment interaction
Explanation:
Schizophrenia is a disorder associated with the psychology and mental make up of the person. The person interprets the reality abnormally. This is associated with hallucination, disordered behavior and delusions.
The gene and the environmental interaction both play an important role in development of this disorder. The environment factors like stress can be dominant over the gene expression. If a person has genes for development of schizophrenia along with the stressed environment then the chances of development of schizophrenia will be prominent.

Hebb's postulate from 1949 states "When an axon of cell A is near enough to excite cell B and repeatedly or persistently takes part in firing it, some growth process or metabolic change takes place in one or both cells such that A's efficiency, as one of the cells firing B, is increased." Give an example of how synaptic plasticity results in: a. Growth processes b. Metabolic changes
Answer and Explanation:
Synaptic plasticity can be defined by the dynamic state capable of producing and enhancing selectively the direction and the activity of neurons in neural circuits.
Synaptic plasticity may play important roles during growth because it is a feature that has the potential to act as a feedback in order to excite and inhibit functions associated with signaling pathways. For example, it has been shown that neurotrophins modulate the synaptic plasticity, thereby controlling the growth and development of the central nervous system.
Synaptic plasticity may also be associated with metabolic changes. For example, the synaptic plasticity enables to modify those cellular preferences associated with the use of energy derived from fats and carbohydrates in the cell.

Suppose that out of 10 trees planted in a yard, only five survive. What kind of hypothesis could you make about this observation or event? Remember that a hypothesis need to have a certain format
Answer and Explanation:
Hypothesis: Half of the trees could not survive because the yard is exposed to extreme environmental conditions to which the plants were not able to adapt.
A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.
A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relation between variables. It must be objective.
There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.
The hypothesis example proposed for the trees´ survival situation, belongs to a causative hypothesis, where cause and effect relations between variables are proposed. In this case, as the environmental conditions in the yard were too extreme, half of the trees could not survive.
Answer:
Based upon the experience with the trees, I’d make the hypothesis that my yard was not sustainable enough to support all of the trees, so only half lived.
