You are a scientist working on an experiment with plants in order to test Mendel's findings. You know that he selected true-breeding varieties because they all have offspring exactly like the parents. Why is this an important factor in these experiments? -Using True-breeding varieties allows you to track a specific plant variety and not have characteristics of other plants interfere with your data.
-Using True-breeding varieties allows you to know that you don't have mixed-breed of plants types.
-Using True-breeding varieties is cheaper and more cost effective than using a fancy type of plant
-Using True-breeding varieties allows you to trace traced the inheritance of individual traits from parents to offspring, with certainty that no other factors are influencing the outcome.

The pea aphid, a type of insect, contains light-capturing pigments in its exoskeleton. pea aphids gained the ability to synthesize these pigments from genes transferred from fungi. while pea aphids do not have chloroplasts or fix carbon, researchers have found that pea aphids with more pigments have higher levels of atp than those with fewer pigments. pea aphids also have been shown to increase production of atp when exposed to sunlight. based on this information, is the pea aphid a true autotroph? a. yes, because the pea aphid can store energy from the sun in atp molecules. b. no, because the pea aphid is unable to use the energy from sunlight. c. yes, because the pea aphid does not need to use energy from food. d. no, because the pea aphid does not store energy from the sun as sugars.
