- Mountain gorillas are a highly endangered primate species, with 800 or so individuals surviving in the two remaining populations. A recent sampling of mountain gorilla genomes revealed a very low level of genetic diversity. Explain why a decline in genetic diversity often accompanies a decline in population size.26. Biologists studying living primates in recent years, such as Geladas and Baboons, have noticed that some of these species may still be able to successful reproduce viable and healthy offspring despite great morphological differences. As well as geographics isolation between these species of hundreds of thousands or several million years. These species known as ___ may pose a problem for identifying different species in the fossil record. a. Chronospecies b. Founder species c. Species isolates d. SyngameonsCaughly’sresearch on the distribution of three different species of Australian kangaroos(Macropus giganteus, M. fuliginosus, and M. rufus) suggests the:a.physical environment limits the distribution of the kangaroos.b.topography limits the distribution of the kangaroos.c.amount of rainfall limits the distribution of the kangaroos.d.temperature limits the distribution of the kangaroos.e.none of the choices apply

An example(s) of environmental conditions is/are: temperature nutrients sunlight all of these. Part B)DR TJ freaks out because she doesn’t hear any cicadas singing in January. If she understood the biology of these animals she would know that was because adult cicadas do not emerge from underground until summer! Dr TJ should have a better understanding of the importance of ___ in studying ecology. timing spatial distributions none of these Part C)If I read 50 papers on phenotypic plasticity in sea stars and they all showed that these animals exhibit behaviors that allow them to persist under temperature stress, this would be an example of ____ in science. detection measurement repeatabilityExplain at least one reasonable hypothesis about what caused the extinction of the dinosaurs at theK–T extinction (abbreviation of Cretaceous–Tertiary extinction) also called the K–Pg extinction or Cretaceous–Paleogene extinction event about 66 million years ago.
- Only when extensive genetic data became available were scientists able to definitively resolve the relationship between humans, chimpanzees and gorillas. Explain why the relationship between these three species was a particularly difficult challenge to solve. Important point. Explain why the relationship between these three species was a particularly difficult challenge to solve?? I don't really see that in your answer. I posted this question 3 times but answer given me wrong.The 2020s have been rough to say the least, and the world is desperately in need of some good news. Nay, not just good news, we need a hero. Enter DiegoLinks to an external site., who fathered 800 offspring to save his species (the Española Galapagos tortoise). The population now sits at 2,000 tortoises and Diego is going home. As we saw last week, population size is important. Ideally, this means you started with a lot of genetically diverse founders, but of course that isn’t always the case. In the case of the Española Galapagos tortoises it was 12 females and 2 males. So, often you have to grow your population to stabilize it and ensure there isn’t an unacceptable loss of genetic diversity over time, even if that genetic diversity is low. If you think back to the math from last week and do a little not so fancy algebra, you can see that genetic deterioration occurs at a rate that is the inverse of genetic retention, which you probably remember is 1- (1/2Ne) The above…Insects are the largest group of animals on Earth. Insectdiversity is greatest in the tropics, where habitat destructionand species extinction are occurring at an alarming rate.What biological, economic, and ethical arguments can youadvance to persuade people and governments to preservethis biological diversity?
