Answer: d. tundra
Explanation:
Polar bears are present only in the Arctic tundra biome. The most important areas for polar bears in the arctic are are the edges of pack ice where the wind and water interact, which createsa constant refreezing and melting network of leads (open spaces in the sea ice) and ice patches.
A polar bear has a fat layer under the skin that helps it stay warm and the big paws help a polar bear walk through the snow.
Hence, the correct option is D. Tundra.

An angle bisector is a line segment that splits an angle into two equal halves while a perpendicular bisector is a line segment that divides the other line segment that is opposite to it perpendicularly.
- Angle bisector and perpendicular bisector are similar as the angle is split in two by both.
- Perpendicular and angle bisectors differ in the way that an angle bisector is not required to make a perpendicular angle with the opposite side, but a perpendicular bisector must.
- The perpendicular bisector makes a right angle from a horizontal line, in contrast to the angle bisector, which divides an angle in half. They both "divide" the object in two.
- A line known as a bisector divides an object into two equally sized portions. A line that cuts through an angle to produce two identical angles is known as an angle bisector.
- For instance, if we establish an angle bisector with a 90-degree angle, the line that passes across the angle will produce two new 45-degree angles.

The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.
<u>What is the end product of light reaction in photosynthesis?</u>
The energy from sunlight is converted into a small amount of ATP and an energy carrier called NADPH. Together with carbon dioxide, these are used to make glucose (sugar) through a process called the Calvin Cycle. This is the things happening during light reaction of photosynthesis .
