Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface.
The correct answer is "behavioral consequences of alcohol intoxication".
Caffeine is a component mainly from coffee and other beverages such as soft drinks and energy drinks. It acts as a stimulant by binding to the adenosine receptors in the brain; blocking the actions of adenosine in the CNS (adenosine works to signal tiredness). In turn, there will be increased alertness. This does not affect the behavioral consequences of alcohol intoxication as these two works in different pathways.
On the other hand, caffeine ingestion affect the risk of cardiovascular disease as it increases heart rate and myocardial workload; it increases the time to fall asleep; and increases the performance in doing boring repetitive tasks.
Answer:
a transgenic copy of the gene C is sufficient to restore normal eye development
Explanation:
In genetics, there are diverse approaches to determining a gene's function. For example, it is possible to use a complementation test to determine loss-of-function recessive mutations when it is unknown if such mutations fall in the same or in different genes. Similarly to the generation of loss-of-function phenotypes, it is possible to insert a gene and thus produce a gain-of-function mutation that restores normal gene function (i.e., to restore the wild phenotype). Moreover, transgenic organisms refer to genetic engineering techniques by which any foreign or modified gene is inserted in the genome of an organism, which can also be used to study gene function. In this case, the restoration of the normal phenotype (wild-type eyes) is associated with the expression of the transgenic gene C, thereby evidencing that the gene C is required for normal eye development. In the last years, transgenic models have shed light on developmental pathways and on gene function.
