I did some research and the answer is "the process where information from the gene is used in a gene product." Gene expression is used in order to allow genes to function in the body so they process information from one gene to another in order to have each gene function correctly.

Hope this helps!

dangina [55]

Answer:

Option A, most closely related to mammals

Explanation:

Insects like arthropods and molluscs have an open circulatory system and thus do have a distinguishable heart. Fish has two chambered heart. Reptiles have three chambered heart. Amphibians too have a three chambered heart.  

All mammals and fish have four chambered heart. The right and left sides of the chambers have restricted entry and hence remain intact from each other

Hence, option A is correct

The mitochondrial matrix has what charge compared with the intermembrane space?
Solnce55 [7]
The matrix (inside mito) has a negative charge compared to the intermembrane space (outside of mito but still inside) because positively charged protons are constantly pumped from the matrix to the intermembrane space. A cell oxidizes an organic molecule producing 3 NADH molecules and 3 FADH2 molecules..

A scientist develops a chemical that prevents golgi bodies from functioning. contrast the specific effects the chemical would ha
snow_lady [41]

The role of the Golgi body or Golgi apparatus is to package the proteins in vesicles and target it to their respective place of function. Example, the receptor proteins that are synthesised in the Endoplasmic Reticulum will be sent to the Golgi body for its packaging into the vesicles that bind and fuse with the cell membrane. The targeting is done by the special set of markers present on the secreted vesicle. All the eukaryotic cells have a Golgi apparatus. When chemical treatment is done to stop its functioning, the cell stops functioning and eventually dies due to the hampered targeting of proteins to the various organelle. On the other hand, prokaryotic cells lack Golgi body as the cell size is small enough to allow for the synthesised protein to move by diffusion to its target. Hence no effect will be seen when prokaryotic cells are treated with that chemical.
