Answer:
Nitrate
Explanation:
Bacteria can direct their movements according to the presence of particular molecules found in the environment. Chemotaxis enables the movement of bacteria in response to environmental factors, including chemical factors. Nitrate is an anion (i.e., negatively charged) that acts both as an electron acceptor during anaerobic respiration as well as a source of nitrogen during aerobic growth. Bacterial nitrate chemotaxis is a phenomenon that occurs under environmental conditions associated with nitrate starvation (i.e., nutrient stress), during the life cycle of diverse types of bacteria. Moreover, methyl-accepting chemotaxis proteins are receptors widely distributed in the cytoplasmic membrane of bacteria and archaea. These receptors form hexagonal arrays that act in signal transduction pathways by processing environmental inputs (in this case, nitrate conditions).
Complementary strand to that would be:
AACGTGC

The answer for the above question is the Euglenid. These are a protist characterized by one or more whiplike flagella that are used for locomotion and by a photoreceptor that detects light. These are photosynthetic, however if they are deprived of chlorophyll, some are capable of heterotrophic mode of nutrition where the ingest already made food.

Answer:
True
Explanation:
Each silk connects to an individual ovule (potential kernel). A given silk must be pollinated in order for the ovule to be fertilized and develop into a kernel. Up to 1000 ovules typically form per ear, even though we typically harvest only 400 to 600 actual kernels per ear.
Technically, pollination is almost always successful (i.e., the pollen reaches the silks), but unsuccessful fertilization (i.e., pollen tube failure, silk failure, pollen death) will fail to result in a kernel.
