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.
What happens after the mRNA transcript is formed in the nucleus to mark its destination
What will happen if reading the code in two pairs of nucleotides is not sufficient
Answer:
The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

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.

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.

Viruses evolve and reproduce. They have genes encoded on nucleic acids.
They are not able to reproduce without a host. They don't have their own cytoplasm.
Prokaryotes have beneficial roles in the carbon and nitrogen cycles. They help to make the carbon in the air usable by plants and break down nitrogen into the reactants that can be used by other organisms.
Viruses recognize specific receptors that are embedded in their host's cell membranes. These receptors are normally used by the cells as gateways, but viruses can insert their DNA or RNA into them. That they must recognize specific receptors limits them to only infecting the species that have that particular receptor. They can infect cells because they're designed in such a way to only infect species and cells. Once inside the cell, the virus can begin reproducing.
Metagenomics has advanced our understanding of how prokaryotic organisms exist and function in natural ecosystems. We are coming to understand that different species assemblages are associated with different health outcomes.

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.
A mutation causing an addition or a deletion of one base pair resulted in the production of a nonfunctional mutant protein. The sequences of the normal and mutant proteins are given below. Normal: Met - Tyr - His - Glu - Val Mutant: Met - Phe - Thr - Lys - Cys - Lys - Trp - Arg - .....
Was this mutation cause by an insertion or a deletion?
Answer:
Explanation:
The mutation was caused as a result of deletion of one letter of the codon A from tyrosine leading a shift in the reading frame.
Normal is
Normal - Met - Tyr -His- Glu- Val
Aug- Uac- Cac - Gaa -Gug
When a is removed from Tyrosine codon we have a shift in the reading frame to form a mutant with a new codon and protein.
Mutant - Met- Phe - Thr - Lys -Cys
Aug- Ucc- Acg - Aag -Ugu
Mutation is a sudden change in the genie of an organism that can be heritage by offspring from their parent.

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.

Examples of homozygous recessive?
Answer:
Please mark as brainliest....thanks!!!
Explanation:
An organism can be homozygous dominant if it carries two copies of the same dominant allele, or homozygous recessive if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene.
A homozygous recessive allele combination contains two recessive alleles and expresses the recessive phenotype. For example, the gene for seed shape in pea plants exists in two forms, one form (or allele) for round seed shape (R) and the other for wrinkled seed shape (r)
