It was also found that an increase in testosterone during the PASP predicted subsequent willingness to choose competitive tasks (3, 28, 29). ... Aggression research in human studies has revealed an interesting property of testosterone dynamics, its rapid fluctuations provoking reactive aggression in response to stimuli.
In his experiment mendel first crossed tall and short peas plant and noticed that the F1 plants were all tall. in the second experiment he crossed the the F1 plants and noticed that short plants reappeared in the rate of 25% in F2 generation. in his third experiment he crossed he crossed F2 plants and noticed that when he crossed some tall plants with the shot plants the F3 generation contained short plant in frequency of 50%. after this observations mendel concluded that there were genes that could be only expressed in homozygous state but not in heterozygous state. these genes were later referred to as recessive alleles wheres the genes that prevented the expression of recessive genes were later referred to as dominant genes.
Answer:
Nuclear energy produces radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years
Explanation:
:>
Answer:
A. The version of the trait that is expressed over other alleles for the same trait.
Explanation:
It is called dominant because if it is present, even in heterozygous situations, it will be expressed.
Answer:
It is likely that the genomic sequences that were used did not enable to properly observe the evolutionary relationships among the species analyzed
Explanation:
The homology level between the genomic sequences may be too low to separate species that are phylogenetically related. In these cases, it is necessary to make a genetic analysis of the sequences that are used before the phylogenetic analysis
