Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment and are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Hope this helps :))
Pathogens are harmful because they are tiny organisms like a bacterium, a fungi, or a virus that causes people to be sick. It causes diseases like the rhinovirus which is the cause of common cold. It is commonly found in hospital wastes and even the water used in swimming.
Answer:
Chemical residue remain on the vegetation.
Explanation:
The negative effects of chemical control of weeds on rangelands is that the chemical residue remain on the vegetation in rangeland which is dangerous for animals that feed on vegetation because the chemicals are toxic that cause serious damaged. Sometime the chemical also damaged the weeds as well as vegetation of rangelands and also kill the beneficial insects that is needed by the plants present in rangelands.
A metabolic manner referred to as cellular respiration converts glucose to ATP. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the stages of cellular respiration.
Four steps of Cellular Respiration
- Glycolysis. During glycolysis, the six-carbon sugar glucose is going thru some of chemical changes. In the end, it's miles converted into molecules of pyruvate, an natural molecule with 3 carbons.
- Oxidation of pyruvate. The mitochondrial matrix, the inner most compartment of the mitochondria, gets every pyruvate produced for the duration of glycolysis.
- Cycle of citric acid. A four-carbon molecule and the created acetyl CoA engage and go through a chain of events, in the end renewing the preliminary four-carbon molecule.
- Phosphorylation through oxidation A gradient is created as protons are pumped out of the matrix as electrons flow down the chain, liberating power as they do so. Through the introduction of ATP through the enzyme ATP synthase, protons float returned into the matrix.
Chemical Energy: C6H12O6 6O2 → 6CO2 6H2O (in ATP)
According to the equation, oxygen (O2) and glucose (C6H12O6) react to provide carbon dioxide (CO2) and water (H2O), which releases power. Cellular respiratory is an cardio manner because oxygen is essential for it to occur.
