The human brain not considered to be a living organism because is doesn't have many qualifications that are need to stay alive. For example it does not repoduce or feed on anything. Unlike humans that are living do.
Answer:
Being distant cousin to oak trees means that in the phylogenetic analysis we might have a common ancestor with the oak tree in the past. Phylogenetics is the branch of biology which depicts the evolutionary relationship among organisms.
The phylogenetic connection with the oak tree is somewhere far away and we do not share an immediate connection with the oak tree.
On the other hand, being first cousin means that there might be a connection ancestor for the different organisms in the near past.
Answer:
Explanation:
The woman with the question mark is not sure if she has the HD disease,
The mother had no history of the disease this means she is not a carrier of the disease but we are not sure of the fathers genotype.
If the father is a carrier in an homozygous dominant form(aa) and the mother does not have the disease her. gentotype is AA
A A ×aa
Aa Aa Aa Aa This means all their offspring will be Carrier of the disease because each parents contributes 50% of the gene their offspring is made of.
The probability that she is sick is 0% but she could be a carrot of the disease in an heterozygote form
If the woman who is a carrier (Aa)of the disease marries a man with no history of the disease(AA)
Aa ×AA
I
AA AA Aa Aa
The probation of their offspring being a carrier in heterozygous form is 50% while the probability of the offspring being dominant of the disease is 0%. Hence, she should not be afraid since her mother and husband who could have contributed to determining the gene of this offspring are not carriers of this gene the offspring are safe.

Answer;
Independent assortment
Explanation;
According to the law of independent assortment; During meiosis homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other.
This process results to the formation of gametes that have a unique combination of chromosomes.
