The correct answer is the group of Romanian orphans adopted by Western families.
Harry Harlow is an American psychologist known for his highly controversial experiments on the maternal and social isolation in Rhesus monkeys. These experiments along with several previously developed theories formed the attachment theory. Harlow's experiments showed that monkeys isolated from their mothers at birth, exhibited later on in life aggressive behaviour and were unable to form social relationships. These experiments suggested that maternal separation can lead to animals with antisocial behaviour.
At the end of the Ceausescu regime in Romania, a big number of orphans were adopted in Western families. These orphans experienced poor living conditions in Romanian institutions, with no social interaction or proper nutrition. Romanian and British scientists followed the progress of these adopted orphans and the results suggested that this early deprivation was the cause of some social deficits. However, scientists are optimistic that these deficits can be reversed in some cases.
Comparative embryology is the branch of embryology that compares and contrasts embryos of different species. It is used to show how all animals are related.
1. Red-shift, which is basically the Doppler Effect, but with light. Because stars in other galaxies appear to give off red light, this shows that they are moving away from us (Earth). Red light is on the far left of the Visible Light Spectrum, so things moving away from us appear to be red, while things moving towards us appear blue (the other end of the spectrum). This suggests that the universe is expanding all the time - and therefore it might have started from a single explosion - the Big Bang.
2. Cosmic Microwave Background Radiation (CMBR) has been found by scientists to be coming from all directions in space, and is suspected to be 'left over' energy from the Big Bang.
Answer:
1. Improvements in telecommunication
2. Improvements in global travel
Explanation:
Global culture refers to <u>the transmission of beliefs, values, and ideas around the world that has a significant impact in the behavior of society</u>. This has been evolving through time, especially since the Industrial Revolution. Today, we are capable of communicating with other people as quickly and easy as ever in the history of humanity and this will keep evolving as technology evolves as well.
This evolution is due to science and technology, especially to the improvements in telecommunication, which <u>enables us to communicate with people from other countries through calls, social media messagings, e-mails, etc.</u>, and to the improvements in global travel, which is <u>much more accessible today than it was before, allowing individuals to move from one country to the other easily and constantly and improving socialization between people from different cultures and backgrounds.</u>
