Answer:
Brian feels that no matter what he does, he will not be good at math because he was born without strong math skills. Brian is demonstrating <u>the entity theory of intelligence</u>, which MOST likely will reduce his ability to learn.
Explanation:
The entity theory of intelligence refers to an individual's belief that intelligence and ability are fixed traits. For entity theorists, if perceived ability to perform a task is high, the perceived likelyhood for mastery is also high.
D can be eliminated because the temperatures where changed in 3 ways, not two.
A is true, but doesn't apply to the actual experiment "design"
B we don't know for sure, it just looks like a cup/glass.
Best answer for you: C
C is true- it was tested with a single independent variable (one that does not change) on multiple trials (the different temperatures)
Answer:
The stomach produces hydrochloric acid.It kills many harmful microorganisms that might have been swallowed along with the food.The enzymes work best in acidic conditions-at low pH
Answer:
Sunlight hits a smaller surface area at the Equator so heats up quickly compared to the poles. Explanation:
Answer:
C) Through genomic imprinting, methylation regulates expression of the paternal copy of the gene in the brain.
Explanation:
The pattern of gene expression wherein either paternal or maternal gene is expressed in specific cells while the other one is prevented from expression is known as genomic imprinting.
In the given example, the maternal copy of the gene on chromosome 15 is expressed in brain cells while its paternal copy is not expressed in these cells. Hence, the pattern of expression of this gene is regulated through genome imprinting. One of the mechanism is methylation of cytidine residues of CpG islands of the DNA that are more frequently present within promoters of the genes.
When the cytidine residues of these sequences are methylated into 5-methylcytidine, the transcription factors do not bind to these promoters preventing the expression of these genes.
Hence, methylation of cytidine residue in CpG islands of the promoters of the gene present on chromosome 15 could have silenced its expression in brain cells.
