<span>T he type of selection that favored progressively larger brain size in human evolution is
</span>directional selection. Directional selection is a type of natural selection (besides stabilizing selection, disruptive selection, kin selection,..)<span> in which an extreme phenotype is favored over other phenotypes. Because progressively larger brain size is an extreme phenotype this is a directional selection.</span>
Answer:
d. transcription factors
Explanation:
Transcription factors are the proteins present in cells that are involved in the regulation of gene expression. The transcription factors may increase or decrease the expression of a gene. Therefore, a transcription factor may serve as an activator or repressor for a gene. These proteins bind to a regulatory sequence present near or within a gene, interact with RNA polymerase or other transcription factors and thereby, affect the transcription initiation.
Since binding of dioxin to certain proteins alter the pattern of gene expression in the cells, these proteins are the transcription factors. For instance, dioxin may bind to a transcription factor and up-regulate the expression of genes which in turn regulate the cell division.
The answer would be Four.
The olfactory cortex (nucus) of the temporal lobe is where the nerve fibers of the olfactory bulb projects directly. This cortex is where you get the smell sensation before determining what the smell actually is. The olfactory cortex is located on the medial aspect of the temporal lobe, particularly in the uncus or the piriform lobe. It is also called the Rhinoencephalon or the nose brain.
Answer:
Her perspective is compatible with: <u>Biopsychosocial</u> medical model.
Explanation:
This model refers to the connection of a medical model that involves three important aspects of a human life such as it's biologycal, psychological and social sides. The biological part has to do with her back pain. This is interfiering with her performance at work which has to do with the social aspects. The psychological aspect interferes with her being able to performe well.
