Answer:
See below.
Explanation:
Belemnites is a genus of an extinct group of cephalopodsThese cephalopods existed in the Early Jurassic period from the Hettangian age (196.5–199.6 million years ago) to the Toarcian age (175.6–183.0 million years ago). Therefore, the discovered rock could be anywhere from 175.6 - 196.5 million years oldHow could Flor explain why all three species share some body structures and have some differences? Why do only house geckos and Pacific gulls have two temporal holes in their skulls?
The similarities in the structure of the three species is due to their sharing a common ancestor while the differences is due to adaptation.
What is divergent evolution?Divergent evolution is evolution where individuals who shared a common ancient ancestor process to have differing structures due to differences in their habitats.
All three species that Flor observed having similar structures is because they had a common ancestor.

How does natural selection enable species to changes their body shape, appearance, and/or size over time? *
A) Individuals that are better adapted to their environment survive and reproduce.
B) Overproduction provides food for stronger members of the species.
C) Environmental changes kill weaker members of the species.
Answer:
A
Selective pressures( Predators, less food etc. ) will cause the less fit variation of a species to decrease in population, causing them not to be able to reproduce. The more fit variation would be able to reproduce more so that over time, the individuals in the species will have the features of the more fit variation.

a) Based on this information and the food chain below, what are the implications of
not taking immediate steps to reduce CO2 emissions in the atmosphere? (2 points)
algae → snails — crabs — salmon → man
b) Because killer whales are at the top of many food chains, it may seem as if they
are not at risk of starving if seals die off. Why is this not necessarily true? (2 points)
Answer:
a) Higher carbon dioxide levels means a rapid growth of Algae, especially toxic blue-green algae that can float to the surface of the water. This growing amount of Algae will expand across the ocean and clutter it. Harmful algal blooms can be harmful to aquatic life, as some produce toxins that can make animals sick, while others can die off in large quantities and deplete oxygen in the water when they decompose. Snails, specifically aqaurium snails, crabs, and salmon do feed on Algae, which could control it to a degree. However, as the ocean becomes more acidic, it could dissolve the shells of crabs and snails, which will cause them to cook in the sun, and therefore die out. As for salmon, studies showed that high CO2 concentrations disturb fish acid-balance, induce stress response, increase nephrocalcinosis incidence, energy metabolism, and feed conversion ratio, and reduces body condition factor, feed intake, and growth. Fish in this condition are very vunerable to dying despite food being all around them. Additionally, fish in those conditions are not suitable for consumption, which means less food for mankind.
b) This is not true. Although they eat sharks, whales, and dolphins, that is just occasional. Seals are their primary meal. As the killer whale is a consumer, it cannot provide food/energy for itself, therefore relying on organisms below it on the food chain. The killer whale predominately consumes seals, being it’s only large predator, killer whales are crucial to the stabilisation of seal population.

D) According to the graph, obesity and diabetes are intertwined, which could be why obesity and diabetes are linked.
E) Diabetes had the greatest rise in prevalence in 1997 until 2000, with prevalence percentages between about 76% to 78%.
Explanation: Explanation for these answers are below:
D) Looking at the graph, obesity and diabetes had similar prevalences in 1997 and 1998, and started to part ways a little in 1999. In fact, even without the graph, scientists have known for a long time that people who have obesity also have diabetes. This graph supports that claim because of how closely linked diabetes and obesity are and how similar the prevalence percentages are.
E) Diabetes had the greatest rise in 1997 to 2000, which had a 78% prevalence by 2000. Obesity had very similar prevalence percentages from 75.5% to 77% in 1997 to 2000.
