KASTLE - MEYER COLOR TEST can be used to determine if a stain is blood or not.
Kastle - Meyer color test is a presumptive blood test that is used to determine whether a stain is a blood or not. It is an easy and reliable forensic method of determining the nature of a stain in crime laboratory. The test involves using the indicator, phenophtalein to determine if hemoglobin is present in a stain. A positive result is obtained it the phenophtalein turn to a bright pink colour when it comes in contact with the stain.
The correct answer is D) Altered ecosystems
Answer:
D) altered ecosystems
Explanation:
just took the quiz
1. Catabolism of glucose in glycolysis and pyruvate oxidation.
2. Oxidation of intermediates in the Krebs cycle.
3. Formation of a proton gradient by the electron transport chain.
Cellular respiration include the metabolic pathways of glycolysis, the Krebs
cycle, and the electron transport chain which perform different roles in
ensuring ATP is produced by the cells.
1.Catabolism of glucose in glycolysis and pyruvate oxidation-This process
facilitates the production of NADH which is used in the electron transport
chain. It also produces acetyl-CoA which is the starting substrate which
enters into the Kreb's cycle and energy used for phosphorylation of ADP to
form ATP.
2. Oxidation of intermediates in the Krebs cycle- This results in NADH or
FADH₂ being produced and used in the electron transport chain. It also
produces GTP (guanosine triphosphate) used in the phosphorylation of ADP
to form ATP.
3.Formation of a protongradient by the electron transport chain-The flow of protons through membrane-bound ATP synthase provides energy used phosphorylation of ADP to form ATP.

Cellular respiration included the metabolic pathways of glycolysis, the Krebs cycle, and the electron transport chain is described below.
Explanation:
1. Catabolism of glucose in glycolysis and pyruvate oxidation-Produces NADH for use in ETC.Produces acetyl-CoA for entry into kerbs cycle.Provides energy for phosphorylation of ADP.
2. Oxidation of intermediates in the Krebs cycle-Produces NADH or FADH2 for use in ETC.Releases high energy electrons for use in ETC.Provides energy to pump protons against their concentration gradient.Produces GTP for phosphorylation of ADP.
3. Formation of a proton gradient by the electron transport chain-The flow of protons through membrane-bound ATP synthase generates ATP.Provides energy for phosphorylation of ADP.
