That hominids can be very alike but also very unlike.
Hope it helps
Answer:
One possible explanation for why <u><em>maternal age</em></u> is a primary risk factor for autosomal trisomy is that oocytes remain in meiosis I until ovulation, which could take<em> place many years after birth, making them more susceptible to damage.</em>
Explanation:
Increasing age becomes a risk for abnormal children like children with autosomal trisomy because as the age of the female increases, the chances of abnormal division of chromosomes in the egg of the female also increases. After the age of 30, the chance of having a baby with autosomal trisomy increases exponentially. The risk primarily increase because of the abnormalities in meiosis in the women.
Answer:
Mendel's Laws are a set of basic rules on the inheritance of characteristics from parent organisms to their children. They are considered rules rather than laws, since they are not fulfilled in all cases. Mendel's first Law of equitable segregation establishes that during the formation of the gametes each allele of a pair is separated from the other member to determine the genetic constitution of the filial gamete, the two alleles, which code for each characteristic, are segregated during the production of gametes through meiotic cell division. This means that each gamete will contain only one allele for each gene. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation. For each characteristic, an organism inherits two alleles, one for each relative. This means that in somatic cells, one allele comes from the mother and one from the father.
Explanation:
Mendel's laws reflect chromosomal behavior during meiosis: the first law responds to the random migration of homologous chromosomes to opposite poles during anaphase I of meiosis (both alleles and homologous chromosomes segregate equally or 1: 1 in gametes) and the second law, to the random alignment of each pair of homologous chromosomes during metaphase I of meiosis (whereby different genes and different pairs of homologous chromosomes segregate independently).Even though not all genes are inherited in the proportions described by Mendel, they are undoubtedly all inherited in the same way, that is, the alleles or different alternatives of a gene are separated in meiosis and each gamete will carry only 1 of them (2nd Mendel's Law) and in turn all genes on different pairs of chromosomes are transmitted independently. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation.Therefore, of each possible genotype for a two three or more genotypes it is possible to know how many gametes it will form, in what proportions and therefore predict results of crosses.
Answer:
Exothermic because it doesn't take place inside something, rather on the outside. :)
Answer:
The correct answer is a tRNA brings over the correct amino acid by using the anticodon to match to mRNA during translation
Explanation:
tRNA or Transfer RNA play an important role during the translation process.tRNA contain anticodon that interracts with the codon of mRNA molecule with the help of Ribosome to bring the amino acid to its own acceptor arm. The amino that is brought to acceptor arm of tRNA is specific for the codon present in mRNA.
tRNA then moves to the P site and a new tRNA bind to the A site of ribosome and brings a new amino acid that form peptide bond with previously generated amino acid. Then process continue untill the tRNA recognizes a termination or nonsense codon
