If a student is making flashcards to help them study for a test on Earth's internal structures, which statement below should they NOT include while studying?

A. Earth’s liquid inner core creates a magnetic field.

B. Scientists use seismic waves to study the Earth’s structure.

C. Materials that make up the Earth’s layers have different densities.

D. Earth’s core can’t be studied directly because of its extreme internal heat.

B.) Scientists use seismic waves to study earth structure

Explanation:

the question is asking for what they use to study the structure is it asking about the structure

c. heat from the poles back down towards the equator.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
