Answer:
False
Explanation:
Gametes are formed by meiotic division, and classified by shape, size and activity. In some species they are undifferentiated, that is, isogamous, resembling, but not identical, regardless of gender. However, most species have heterogeneous gametes (anisogamy), differentiated by morphological, dimensional and mobility aspects.
Answer:
Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.

Answer:
constructing dams and building desalination plants help reduce the effects of droughts
Explanation:
The main type of evidence the scientists used is fossils.
Palaeontologists study plants and animals that existed in the geologic past. To do so, they use fossils and try to determine an organism's evolution and relationship with the environment and other organisms. In this example, palaeontologists used fossils from ancient horses that have gone extinct and try to decipher their evolutionary path. Recognising the evolutionary steps of the ancient horses will make it possible to compare them to the modern horses.
