From implantation through the 8th week, the major body organs and systems become differentiated. This stage of pregnancy is called the period.

Embryonic Period

Explanation:

The embryonic period also known as the stage of pregnancy and it will be prepare in Eight week. The heart is the principal organ to frame during advancement of the body. At the point when an undeveloped organism is comprised of just a not many cells, every cell can get the supplements it needs legitimately from its environment  The early stage arrange keeps going from implantation (2 weeks) until the eighth seven day stretch of pregnancy.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
