The brain is a remarkable and complex structure responsible for thinking skills. Several parts of the brain work together in a sophisticated manner to integrate information and develop thoughts. The term thinking skills refers to a wide range of processes, including consciously remembering facts and information, solving concrete or abstract problems using known information, and incorporating reasoning, insight or ingenuity.
Answer:
meiosis I
Explanation:
Independent transmission is Mendel's second law. Like any Mendel law it is based or is about the transmission of alleles. Therefore, the law of independent transmission is based on the fact that when forming gametes, the alleles of one gene are segregated independently before the segregation of the alleles of another gene. This second law can not only be applied to the characters that Mendel analyzed, which were two genes with two possible alleles, this law is fulfilled with more than two characters. We must bear in mind that alleles are the different forms that a gene can present.
On the other hand we have the concept of meiosis I which is a type of cell division that in animals generally gives rise to gametes for sexual reproduction or sexual spores (in plants and fungi). That is to say in mitosis we find that there is only a cell division between homologous chromosomes, so that from a tetraploid number (4n) we pass to a diploid number (2n). While in meiosis we find that there are two cell divisions in which we go from a tetraploid number (4n) to a haploid number (n). This means that this is a reductive process. These haploid cells will join together to give rise to a diploid cell. Another important concept to consider in meiosis is the formation of chiasmas that are created between non-sister chromatids, thanks to this phenomenon the exchange of genetic material occurs.
Answer:
the greatest effect has been economical as large percentage of individuals are falling ill, hence nobody is working also the health system has been compromised as the high percentage of hiv/aids patients arent allowing for other people to seek madicle assistance
Explanation:
Around ten percent of the adult population of these slums are HIV positive – making them one Kenya's most HIV affected areas. Poor living conditions, extreme poverty as well as a lack of education are main reasons for the spread of HIV/AIDS in the slums of Kenyan capital.
Answer:
Phylogenetic relationships
1. includes all descendants from a single common ancestor >>> monophyletic group
2. does not share any common ancestry but represents convergent evolution >>> polyphyletic group
3. includes some but not all descendants from a single common ancestor >>> paraphyletic group
Explanation:
A monophyletic taxon is a collection of organisms that have the same most recent common ancestor, thereby including an ancestor and all its descendants. Examples of monophyletic groups are angiosperms, mammals, insects, etc. A paraphyletic group is composed of some (but not all) the descendants of the most recent common ancestor. An example of a paraphyletic group includes fish and lizards. Finally, a polyphyletic taxon is composed of a group of organisms that do not contain the common ancestor of all the members of the group. An example of a polyphyletic group is composed of birds and mammals, (which constitutes a group of warm-blooded animals).
Conditioning is the type of behavior involved when the bell
rings at the end of class. Conditioning is a behavioral process in which a
given stimulus or signal (such as a bell) becomes more frequent and effective
in causing the manifestation of a desired response in a given environment.
