Answer:
In the ecosystem, the tides of the water rise in each figure. In figure 4, there is an increase in land animals present, and a lower amount of aquatic animals present. In the first figure, there are no birds, however there are multiple in the rest of the figures, this is possibly due to migration in the winter or that the ecosystem has drawn birds near. The types of plants change throughout each figure which is most likely to new adaptations such as more water available. The tides most likely rose because of more precipitation.

Answer:
a. histones. is the correct answer.
Explanation:
In a nucleosome, the DNA is wrapped around eight histones proteins to create strong loops termed nucleosome.
A nucleosome is the structural subunit of the chromatin.
Chromatin is a fiber polymer of double-stranded DNA which is composed up of a nucleosome core. The nucleosome core is made of histone proteins
Each nucleosome is composed of DNA enclosed around eight histone proteins which are called histone octamer.
Answer:
1a. False
1b. False
Explanation:
They are genetic clones which make them identical so there is no difference in phenotype which is the key mechanism for evolution to occur through natural selection.
- since they are of one phenotype(genetically identical) genetic drift can not occur. For genetic drift to occur, there must be a change in the frequency of one allele within a population over a period of time and this genetic variation must occur randomly for a genetic drift to occur.
