The central nervous system includes the brain and spinal cord.
Answer:
Option D, a test for the presence of cells that contain DNA
Explanation:
As we know all living organisms are made up of cells and DNA is the basic genetic material that codes for protein and traits with an organism. If even a single cell with DNA is detected on the extraterrestrial planet then it will be clear that it has life on it or the environmental conditions are favorable to support life. Cells are microscopic and hence can be seen through microscope which can be installed easily on a probe.
Hence, option D is correct

Answer:
1. Chloroplast
2. cellular respiration
3. ATP
4. C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy
Explanation:
This question is describing the processes of photosynthesis and cellular respiration. Photosynthesis occurs in the CHLOROPLAST, which is responsible for the conversion of solar energy (from sun) into chemical energy (in glucose). The general photosynthetic reaction is:
6CO2(g) + 6H2O(l) + energy → C6H12O6(s) + O2(g)
Contrarily, the process of cellular respiration occurs in the MITOCHONDRIA. Cellular respiration involves the breaking down of food molecules to synthesize ATP (energy) for use during biochemical reactions. The general chemical reaction is as follows:
C6H1206(s) + 02(g) → CO2(g) + 6H20(I) + energy
