Explanation:
PLANT-LIKE:
presence of flagella
shows absence of cell wall, though chloroplast may be present
ANIMAL-LIKE:
slime mold belongs in this category
absence of cell wall, as well as chloroplast
FUNGUS-LIKE:
feeds on decaying matter enclosed by a membrane called a pellicle.
Answer:
Cabbage is a different story. Per capita consumption of it peaked way back in the 1920s, when the average American ate 22 pounds of it per year. Nowadays, we eat about eight pounds, most of it disguised as cole slaw or sauerkraut.
This makes it pretty interesting that kale and cabbage — along with broccoli, Brussels sprouts, cauliflower, collard greens, and kohlrabi, and several other vegetables — all come from the exact same plant species: Brassica oleracea.
In some circles, kale has become really, really popular. Once a little-known speciality crop, its meteoric rise is now the subject of national news segments. Some experts are predicting that kale salads will soon be on the menus at TGI Friday's and McDonald's.
Answer:
Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.
Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.
Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.
Answer:
5.) While it appears in a balanced ecosystem that nothing is changing, there is indeed either subtle or gradual changes that constantly happens through natural succession.
6.) Predator-prey relationships achieve a state of balance:
a.) Prey- They are food for predatory animals and help them thrive with nutrients that they possess.
b.) Predator- They help reduce overpopulation for prey
