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.

Which factors determine whether a cell enters G0?
Delvig [45]

The appropriate answer for this one is C. Cancer cells divide uncontrollably and therefore the cell cycle would be continuously divide. To add, there is a term known as terminally differentiated cells. These cells that never enter the cell cycle again, meaning they stay in G0 and never divide. However, some cells can be triggered to depart G0 and re-enter G1, which permits them to divide again.

Cinnabar colored eyes (cn) and reduced bristles (rd) are autosomal recessive genes and lobe shaped eyes (L) is an autosomal domi
Morgarella [4.7K]

Answer:

The correct genotypic notation for a wild type with phenotypic characteristics: red eyes, long bristle and round eyes will be any of CNRDll, CnRdl, CnRDl or CNRdl if c, n, r and d are capable of independent assortment and CNRDl if they cannot.

Explanation:

The eye color and bristle size is coordinated by either recessive cn and dominant CN or Cn genes. The wild type in questions has red color eyes, which is a dominant trait coordinated by CN or Cn if c and n can undergo assortment independently or just CN if they cannot. The second characteristics of the wild type is long bristle. We were told that reduced bristle is coordinated by recessive rd Gene. Then the long bristle in our specimen wild type will have dominant genotypic notification of RD or Rd, depending if r and d can undergo assortment independently. The last trait is a round eyes, which is a recessive trait controlled by recessive allele l. Therefore, the combined characteristics of red eye color, long bristle and round eyes shape of the wild type will be CNRDl or any of CNRDll, CnRdl, CnRDl CNRdl depending on the segregation pattern of c, n, r and d.

Can we still recover the lost biodiversity? Why or why not?
photoshop1234 [79]

Yes, we can recover it. But not the same as before. Maybe we will make a new one. By planting trees and cleaning the area.The loss of biodiversity has two significant impacts on human health and the spread of disease. First, it increases the number of disease carrying animals in local populations. ... At the same time, habitat fragmentation brings humans in closer and more frequent contact with these disease carrying species.Participating in Biodiversity Conservation. Identify locations of critical wildlife habitat for species at risk and the threats to these areas. ... Keep vehicles on main roads to reduce the spread of weeds and disturbance to wildlife. Monitor and assess your pets' impact on biodiversity.
