tradition based on flaked tools. It consisted of a massive fluorescence of colored cave paintings beginning about 70,000 B.P., which suggests the evolution of color vision and a truly human-style brain organization. It provided the environmental circumstances that selected for the evolution of "Mitochondrial Eve." It provided new environmental circumstances that made important sociocultural adaptations like the development of plant cultivation more likely. It led to the extinction of the Neandertals, who had survived until then by eating big-game animals.

Answer:

It provided new environmental circumstances that made important sociocultural adaptations like the development of plant cultivation more likely.

Explanation:

The broad spectrum revolution is important from the evolutionary point of view and the shift of the human subsistence. This revolution was first explained by Kent.

hram777 [196]

Since, the options have not been listed. All factors that reduce the SIDS is included in the answer.

Answer:

SIDS ( Sudden infant death syndrome) denotes the actual or the sudden death of the infants below one year of the age. This is the leading cause of the death of the infants.

Physical as well as physiological factors might reduce the chances of SIDS. The maintenance of the proper weight in infants reduces the death of infants. The inhibition of the use of tobacco and drugs during the gestation period is also helpful to reduce the SIDS condition. The proper sleep environment and routinely medical checkup reduces the SIDS cases.

g. There's a chance that all four offspring won't adhere exactly to the ratios predicted by the Punnett Squares, because male offspring can only have one trait (on the X).


Hope this helps. I hope you understand that heterozygous is (Big Letter & Small letter) and homozygous is either: Big Letter Big Letter OR Small Letter Small Letter. Have a great night and I hope you are successful in your class!

Olin [163]

Answer:

d a discrete combination of traits, for example Masaai cattle herding.

Explanation:

A cultural complex consists of different cultural traits that together create a 'culture'. Thus, a cultural complex can be defined as a group of cultural traits that are functionally interrelated. A cultural trait can in turn be defined as any acquired knowledge that is learned by social interaction and interpersonal relationships. Moreover, a cultural pattern occurs when cultural traits and cultural complexes associate each other in functional roles.
