Explanation:
Vegetable oil is........................the phospholipids in vegetable oil have fatty acid tails that ARE BEND.
Vegetable oil are made up of unsaturated fatty acids, which means that double bonds are present in the oil. The degree of unsaturation varies depending on the type of oil. The configuration for double bond is cis; this makes the phospholipid in the vegetable oil to have bent structure.
Answer:
The changes in the population of a species in a stable ecosystem has diverse effects on the ecosystem on the whole.
The reduction in the baleen whale population will cause a rapid increase on the prey organisms on which the baleen whale fed. This is because the number of predators for these preys will decrease.
On the other hand, the number of organisms which fed on the baleen whale will decrease as they will have lesser amounts of food available.
Answer:
These changes are not inherited, but occur as random events during the formation of reproductive cells (eggs and sperm). An error in cell division called nondisjunction results in reproductive cells with an abnormal number of chromosomes

Answer:
Letter a. Yes, yeasts can exist in an oxygen-poor environment.
Explanation:
Mitochondria are an organelle that we can find in the majority of eukaryotic cells. Mitochondria help in produces the energetical molecule of ATP. We start with one molecule of glucose that passes through a process called glycolysis to convert glucose into pyruvate. This pyruvate molecule can follow two pathways: when oxygen is available the pyruvate enter into the Krebs cycle and proceeds to the respiratory chain in the mitochondria, when oxygen is not present, pyruvate pass into another pathway, one is the alcoholic fermentation producing ethanol and dioxide of carbon.
As yeast are a eukaryotic organism, they have mitochondria and can grow in the presence of oxygen. When oxygen is absent yeast can grow using the fermentation pathway producing alcohol.
