Answer:
Gene flow would decrease as a result of the alteration of migration patterns. Therefore, the variability of this species would decrease.
Explanation:
Gene flow refers to the<u> transfer or introduction of genes from one population to another</u>. Gene flow enables the introduction of new alleles, therefore increasing biodiversity.
The rate of gene flow between groups of species depends on different factors. For instance, gene flow increases with the ability of a species to move from one place to another and, at the same time, on the possibility of migrating species mating with resident species. This occurs not only with birds but even with humans, when they migrate from one country to another, which increases diversity and variability.
Therefore, <u>if the migration patterns of birds that pollinate a plant species from South America is altered, then there would be less variability within this plant and also with this bird species.</u>
Answer:
Anomalous expansion
Explanation:
Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.
At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.
When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.
This way, organisms can survive in the water due to the lower layer not freezing.
The answer would be D. Four groups
Fungi are usually classified in four divisions: the Chytridiomycota (chytrids), Zygomycota (bread molds), Ascomycota (yeasts and sac fungi), and the Basidiomycota (club fungi).
