Polyploidy is a major force in the evolution of both wild and cultivated plants. ... Some of the most important consequences of polyploidy for plant breeding are the increment in plant organs
Answer:
True
Explanation:
Peristalsis is the wave-like motion of the walls of the alimentary canal that allow food to move along the lumen of the alimentary canal towards the posterior (anus). These waves are powered by the contraction and relaxation of the smooth muscles.
Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources. At the first trophic level<span>, </span>primary producers<span> (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis. Herbivores—animals that feed solely on plants—make up the second trophic level. Predators that eat herbivores comprise the third trophic level; if larger predators are present, they represent still higher trophic levels. Organisms that feed at several trophic levels (for example, grizzly bears that eat berries and salmon) are classified at the highest of the trophic levels at which they feed. Decomposers, which include bacteria, fungi, molds, worms, and insects, break down wastes and dead organisms and return nutrients to the soil

Answer:
dxminxnt allele
Explanation:
if a hetzygous genotype, the dome allele will express the phenotype over the recess allele. therefore, it is the dome trait that'll be commonly expressed as it acts through hetzygous and homzygous genotypes while recess trait only shows up in homzygous genotype.
hope it helps :)
