Problem: Maternal factors also play a role in the body’s immune response. At birth, most of the immunoglobulin present is maternal IgG. Because IgM, IgD, IgE and IgA don’t cross the placenta, they are almost undetectable at birth. Some IgA is provided by breast milk. These passively-acquired antibodies can protect the newborn for up to 18 months, but their response is usually short-lived and of low affinity. These antibodies can also produce a negative response. If a child is exposed to the antibody for a particular antigen before being exposed to the antigen itself then the child will produce a dampened response. Passively acquired maternal antibodies can suppress the antibody response to active immunization. Similarly the response of T-cells to vaccination differs in children compared to adults, and vaccines that induce Th1 responses in adults do not readily elicit these same responses in neonates. Between six to nine months after birth, a child’s immune system begins to respond more strongly to glycoproteins, but there is usually no marked improvement in their response to polysaccharides until they are at least one year old. This can be the reason for distinct time frames found in vaccination schedules.
In babies, what is another element impacting immune response?
The answer is the following: Maternal factors

Problem: Migration in birds is highly labile and is believed to have developed independently in many avian lineages. While it is agreed that the behavioral and physiological adaptations necessary for migration are under genetic control, some authors have argued that no genetic change is necessary for migratory behavior to develop in a sedentary species because the genetic framework for migratory behavior exists in nearly all avian lineages. This explains the rapid appearance of migratory behavior after the most recent glacial maximum.
How was migration developed?
The answer is the following: independently

Problem: Turkish authorities deny the genocide took place to this day. The Armenian Genocide is acknowledged to have been one of the first modern genocides. According to the research conducted by Arnold J. Toynbee, an estimated 600,000 Armenians died during deportation from 1915–16). This figure, however, accounts for solely the first year of the Genocide and does not take into account those who died or were killed after the report was compiled on the 24th May 1916. The International Association of Genocide Scholars places the death toll at "more than a million". The total number of people killed has been most widely estimated at between 1 and 1.5 million.
What is the estimated sum of people who died during the Armenian Genocide?
The answer is the following: between 1 and 1.5 million

Problem: At the end of the 16th century, the Aussa Sultanate was established in the Denkel lowlands of Eritrea. The polity had come into existence in 1577, when Muhammed Jasa moved his capital from Harar to Aussa (Asaita) with the split of the Adal Sultanate into Aussa and the Sultanate of Harar. At some point after 1672, Aussa declined in conjunction with Imam Umar Din bin Adam's recorded ascension to the throne. In 1734, the Afar leader Kedafu, head of the Mudaito clan, seized power and established the Mudaito Dynasty. This marked the start of a new and more sophisticated polity that would last into the colonial period.
Where was the Aussa Sultanate established?
The answer is the following:
Denkel lowlands of Eritrea
