Answer:
DNA, ribosomes, plasma membrane and cytoplasm are the structures that are found in both.
Explanation:
Prokaryotes are the organisms that do not have a nucleus and other membrane-bound organelles and eukaryotes have a membrane-bound nucleus and another membrane-bound organelle.
Apart from this there are some similarities between prokaryotic and eukaryotic cell like both have a highly selective cell membrane, they both have cytoplasm, both have DNA and ribosomes which is responsible for the expression of genes. Therefore DNA, ribosomes, plasma membrane, and cytoplasm are the structures that are common in both prokaryotes and eukaryotes.
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:
The following are the sections which can be seen in a food label:
1) Product dates:
Under this section look for the production date and the expiry date ( best before). The production date tells when the food was made. The expiry date tells the date before which the food has to be used.
2) Ingredient list:
The list of all the ingredients used for the preparation of the food is mentioned.
3) Nutrition Facts Label
At the top of this label, we will see the total number of servings and size of the container. Thus table shows some key nutrients and the percent of them present in the container of food. It also shows the calories of each. Percent Daily Value (DV) shows the percentage of each nutrient present.
The nutrient label are important to an athlete because he/she needs to take a diet which is capable of filling us nutrient requirements. Athletes tend to perform well when they have a balanced diet. To get a balanced diet, they need to look at the nutritional values.
