Bison are found in grasslands. they spend much of there time in herds eating grasses and other small plants. what kind of teeth do bison likely have (a. broad flat teeth for grinding) (b. long sharp teeth for taring) (c. flat sharp teeth for chopping) (d. small sharp teeth for grabbing)

Option-A

Explanation:

Bison are the animals that can be characterized by their short but broad forehead in the temperate grasslands. The Bison has adapted to live in this grassland that is to survive in the dry conditions and the grasses.  

The main adaptations shown by the bison are the teeth that can chew the grasses and their digestive system which can digest the cellulose present in the grasses. Their teeth are broad and flat-topped which can easily grind the grasses.

Thus, Option-A is the correct answer.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
