Acidic solutions have pH of less than 7. Neutral have pH of 7. Basic solutions have pH higher than 7.
The key evolutionary development of animals seen for the first time in sponges is that of Multicellularity. A Multicellular organism has a longer lifespan than an unicellular organism and since it has multiple cells, it can perform more functions. Sponges do not have distinct circulatory, respiratory, digestive, and excretory systems – instead the water flow system supports all these functions.
It becomes pollened and therefor more will come afterwards
Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.
John's genotype with unattached being dominant is Aa.
- Using A to represent the alleles
- Since his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa).
- So for John to have an unattached earlobe, his father has to be either AA or Aa.
- Therefore John's genotype would be Aa

Answer:
Hey!
The formation of the North-Atlantic deep water current involves the conversion of warm salty sea water from the Equatorial area moving to the cold dense deep waters behind the Greenland-Iceland-Scotland Ridge.
The mixture of the warm and cold waters causes the current to form and then moving clockwise from Greenland towrads Scotland and Norway
