1. Using a Key In which year was the number of cichlids the greatest?
2. Using a Key How many years did it take for the cichlid population to decrease
by 50 percent?
3. Inferring Relationships Which fish in Lake Victoria do you think is higher on
the food chain
the cichlid or the Nile Perch? Explain your answer.
4. Identifying Trends Based on the rate of decrease of cichlids shown on the map,

is the DNA in the form of chromatin or chromosomes when a cell finished cytokinesis
Answer:
Cell cycle consists of interphase and mitosis. During interphase there are 3 phases- G1, S and G2 phases. G1 is the resting phase after previous mitotic phase, S phase is DNA synthesis phase and G2 phase is again resting phase.
DNA synthesis occurs before mitotic phase which is the actual cell division phase and chromosomes are condensed during mitotic phase therefore it's in the chromatin form that DNA is synthesised.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
According to the statement, it can be concluded that the three mountains were formed around the same geological era. Additionally, they have similar layers due to the sedimentation and metamorphization processes.
Since its emergence, the Earth has experienced different physical and chemical phenomena that have influenced changes in it. In the case of the lithosphere and the Earth's crust, they have been influenced by phenomena such as
Volcanism The rock cycle The wind The rainfall Among other
Additionally, geologists have developed methods of studying the crust to know the age and composition of the layers of the Earth's crust. According to this, it can be established that these three layers are of the same age because their composition of layers is studied and the materials and distribution of the layers match, that is, they were formed at the same time.
This coincidence in distribution is explained through the processes of sedimentation of materials and their metamorphization.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
The above observation shows that the mountain chains in Northern Europe and West Africa are part of the Appalachian Mountains as a result of the same age, matching of rocks, etc
A mountain chain simply means a row of high mountain summits or a contiguous ridge of mountains within a larger mountain range.
The theory of plate tectonics establishes a co-relation with these mountain chains by understanding their movements. It was shown that Europe and Africa were part of the same landmass in the past. Due to the gradual movement of plates, both continents move apart.
