<span>The
answer is The frontal lobe is in charge of the more accurate, reasoned choices associated
with adulthood. Adolescents are more likely to process emotions in the
amygdala then adults who use the frontal lobe. One of the reasons for bad
decision making in adolescents is the immaturity of the prefrontal cortex.

Answer:
Las células procariotas están rodeadas por una membrana plasmática y al igual que las células eucariotas tienen ADN, citoplasma y ribosomas. También tienen paredes celulares y pueden poseer una cápsula celular. Los procariontes tienen un solo cromosoma de gran tamaño, que no está rodeado por una membrana nuclear.30-Jan-2013
Answer: The probability of having an offspring that is dwarf in size is zero.
Explanation: Since tall phenotype is dominant to dwarf phenotype, let T represent allele for tall and t represent allele for dwarf. A heterozygous pea plant will have Tt genotype while a homozygous tall pea plant will have a TT genotype. A cross between them will produce two homozygous tall pea plants (TT) and two heterozygous tall pea plant (Tt). They will not have any offspring having a dwarf size. Therefore, the probability of having a dwarf offspring is zero.

Answer:
Since both Anthony and Sara are healthy carriers of the gene that causes cystic fibrosis, the chance of having a child with this disease are 1:4 (option D).
Explanation:
The inheritance pattern of cystic fibrosis is autosomal recessive, and considering that both parents carry the abnormal CFTR gene, it can be said that the parental genotypes are:
<em>Anthony N/Qf
</em>
<em>Sara N/Qf
</em>
Where N is the normal gene and Qf is the abnormal gene.
Since this is an autosomal recessive disorder, only the homozygosity of the defective allele will cause the disease to manifest
:
N/Qf X N/Qf
<em>Alleles N Qf
</em>
<em>N N/N N/Qf
</em>
<em>Qf N/Qf Qf/Qf
</em>
- The chances of having a healthy child are 25%.
- The chances of having a carrier child are 50%.
- The chances of having a child with cystic fibrosis are 25%.
Therefore, the chance of Anthony and Sara having a child with cystic fibrosis is 1:4.
