Both of those two independent methods of investigation resulted in the same pattern which means it is significant.
Fossil records explain the history and evolution of life based on fossils. Fossils are remains of organisms preserved in sedimentary rock. In fossil records they are analyzed and arranged chronologically and in taxonomic order, so that can represent the evolution.
Phylogenies describes the relationships between organisms (species): from which organisms it is evolved, to which species it is most closely related etc.
It is used to organize living organisms into specific categories.
Pedigree is the symbolic representation of the history of an individual's family connections, presenting their ascendants and descendants in an organized manner. This is an important instrument in the genealogical process, as it is a way of gathering data about the ancestors of the members who participated in a person's family building so that the connections between these individuals are established.
The family pedigre shown in the above question would be:
Hanna's mother and Hanna's father have three daughters of Hope's order, Holly and Hanna. Hanna and Harry have a son named John. John is married to Jane. His children are Lee and Leah (diagnosed with galactosemia
). Janes's mother is Hilda and the brother is Joe. Joe is married to Jen and his son is Les.
Answer:
Multiaxial joint
Explanation:
Joint is understood as the set of structures that allow the union of two or more bones and / or cartilage with each other. The synovial joint is a union that is established between bones that have different articular surfaces. There are factors that determine the axes of space in which a joint can be mobilized, in such a way that uniaxial, biaxial or multiaxial joints are identified. The multiaxial joint is movements in around three axes or three degrees of freedom. These joints can perform any movement. This movement that is carried out in the three axes is called circumduction movement (in a circle). The movements that a synovial joint can carry out are sliding, extension, flexion, abduction, adduction, medial rotation, lateral rotation, circumduction, protrusion, retrusion, diduction, pronation, supination, inversion, eversion, among others.
Conjugation
The process by which isogamous organisms exchange genetic information during fertilization is called conjugation.
In process of meiosis. The hypothalamus or the master gland in most animals, including humans send signals to the ovaries and testes of the reproductive system. In response to these signals, these ovaries and testes undergoes thesex cells division which is called meiosis<span>. </span>Spermatogenesis <span>in male gametes, is the process of sex cell division among sperm cells. On the other hand, </span>oogenesis<span> is for the female gametes. These cell divisions among respective gametes produces haploid cell which only contain one pair of chromosomes, in number -23.<span> </span></span>
