QUESTION 3 3.1
A scientist conducted an investigation on digestion, involving gastric juice. She
compared the time taken for 50 g of different cooked egg samples to form chyme in the
stomach, with the time taken for the same sample to form chyme in a test tube
containing gastric juice. The test tube was maintained at 37°C.
The results are indicated in the graph below.

"a.) well–developed vascular system."

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
