David is researching caribou for a science project and learns they require

deep frozen ice to walk on while searching for food to survive. Which two

Earth systems are involved in the interaction of caribou and ice?

C. Cyrosphere and biosphere

Explanation:

Caribou are members of the Earth's Biosphere which is an umbrella term for all living organisms on Earth.

The Cyrosphere refers to any and all areas of Earth where water is in frozen form.

David learning that Caribou need deep frozen ice to walk on is therefore an interaction of these two systems as it shows a living organism being the Caribou interacting with deep frozen ice which is part of the Cyrosphere.

there are conflicting perceptions. what cannot be denied is that despite a long history of discrimination, they finally chose to bow out in grace and handed over power to the majority. it was a painful experience for them to part with their prerogatives and some chose to leave the country. however, they did decide to bite the bullet and go through the process with minimum obstructions.

presently, whites are still a force to reckon with. they are well educated, have technical and business expertise, they understand imperatives of good governance and are responsible for keeping south africa connected with developed countries. despite a bitter history, they are useful team members of the south african team.
