Answer:
Gene mutation:
Gene mutation may be defined as change or alteration in the nucleotide sequence of the gene. DNA replication errors and mutagens are responsible for the gene mutation. A single gene may affected in this mutation. For example: Sickle cell anemia is caused by the replacement of GAG to GUG results in the formation of valine instead of glutamic acid. The shape of RBCs changed from the biconcave to the sickle cell shape.
Chromosome mutation:
Chromosome mutation may be defined as the change or the alteration of chromosome number or structure. Chromosome mutation occurs due to errors during crossing over. The segment of the chromosome may get changed. Large number of genes may get affected. For example: Down syndrome occurs due to the presence of extra chromosome at chromosome 21.
Answer:
Evolution is a process that results in changes in the genetic content of a population over time. ... Microevolutionary processes are changes in allele frequencies in a population over time. Three main mechanisms cause allele frequency change: natural selection, genetic drift, and gene flow.
Answer:
b. Scientists are interested in incorporating knowledge of how dolphins accurately transmit and receive information into the design of their tsunami detection networks. The scientists will probably want to investigate if there are any impacts of these networks on dolphins in the area.
Explanation:
Scientists want to study communication between dolphins because these animals are able to establish efficient communication with each other even over long distances. With the knowledge of this communication, scientists can incorporate similar factors into their tsunami information transmission system, so it will be easier to accurately transmit and receive information in the design of their tsunami detection networks.
However, it is necessary for scientists to include in the study, the possible impacts that this system of transmitting information about tsunamis can have on the dolphin population.
In summary, we can say that scientists are interested in incorporating knowledge of how dolphins transmit and receive information accurately in the design of their tsunami detection networks. However, scientists must investigate whether there is any impact of these nets on dolphins in the region.
Anthony has been refusing to go to school. Anthony's culture places great emphasis on academic achievement and expects that young people will get no grade lower than an A, and his teacher wonders whether that may be influencing Anthony's school refusal. This illustrates operation of the Macrosystem.
<h3><u>
Explanation:</u></h3>
Urie Bronfenbrenner has developed a theory of ecosystems in which the macrosystem deals with the culture in which an individual survive. There are five differemt environmental systems that has been dealt with this system in which the individual interacts. They are mesosystem,macrosystem, microsystem, chronosystem and exosystem.
When the culture is dealt as a whole and dealing with poverty,ethnicity,status in socioeconomic context and wealth is Macrosystem. They also deal with children their studies and the working nature of their parents. The example given here deals with an individual's emphasis towards academic and the things that influence him. Thus it illustrates the operation of Macrosystem.
It would be up to 30 molecules of ATP.
