Answer:

The correct option is B: the expression of NMDA receptors is more abundant in hippocampal than cortical neurons

Explanation:

Global Ischemia is known to cause damage to neurons in distinct areas of the brain. The expression of NMDA, a pattern of selective vulnerability capable of being reproduced is usually seen in the dorsal hippocampal of animals, especially rodents, where the neurons in the CA1 area is mainly affected. Thus, this explains why the hippocampal is the area well faced with a high risk of vulnerability during global ischemia.

Explain how heat from the Sun results in convection currents in the ocean
Fofino [41]
<span>The sun's energy is absorbed by the top layer of the ocean water. The water molecules spread apart, become less dense, and cause movement of water. The energy from warmer water transfers to cooler water. Note: Satellite imagery allows you to see this process. Combined with wind currents, water of different densities that is mixing can be seen on the ocean's surface in the form of ripples or swirls.

Alex787 [66]

Answer: Artists use different mediums to make art, and they often specialize in a particular medium throughout their careers, although their style might change over time.

Explanation:

When drawing, they often use ink or pencils. Paintinters use watercolor, acrylic, pastel, and pencils as well. Sculptures are made of glass, stone, clay, aluminum, wood, or any three-dimensional material.

Paintings in watercolor are the kind of medium most often seen.

However, modern art installations have added new mediums. Such is the case of the Korean artist Choi Jeong Hwa. He uses different recycled waste items to build public artworks, like a colossal fish puppet made from plastic bags and buildings made from old doors.
