In the past, preservation efforts usually focused on single species, such as polar bears or Florida panthers. However, current p
reservation efforts generally focus on whole communities and ecosystems. One approach to the preservation of biodiversity on this scale is the establishment of protected areas such as natural parks and reserves. Marine reserves are protected areas in the ocean where harvesting fish and invertebrates is limited or prohibited. Generally, these reserves protect a coral reef ecosystem, a kelp forest ecosystem, or an area near a particular shoreline, rather than a single species. The following graphs represent changes typical after the establishment of some well-planned marine reserves. Interpret the graphs and determine which of the following statements are true? a. Species diversity generally increases in marine reserves.
b. If lobster harvesting is prohibited in an area, sea urchin density would likely increase.
c. Sea urchin density is higher in marine reserves, probably as a result of decreased collection by commercial divers.
d. Although marine reserves help predatory species such as sea otters and lobsters to thrive, there is only a slight effect on kelp.
e. An increase in the number of predators in a community correlates with a decrease in the number of grazers (sea urchins in this case).
f. Organism size increased by about 30% after the establishment of this reserve.
g. Kelp forest recovery in marine reserves is likely due to an increase in predators.
h. The density of all the organisms in an area can be expected to increase after the establishment of a reserve.
i. Because reserves have a higher diversity of species, individuals of each species are, on average, smaller.
831.00, 81.82, 83.5 are the icd-10 code that are reported to a patient who underwent dibridement of the acromion, subacromial and abrasion acromioplasty. Bursectomy and division of the ligament are included in the acromioplasty.The dislocation is not acute but is stated as recurrent.
Promoters are DNA sequences that direct RNA polymerase to the initiation site. Promoter sequences are simply DNA sequences that helps in defining where the gene transcription by RNA polymerase will start.
Promoter sequences are located directly upstream and are an important part of the expression vectors as the binding of DNA to the RNA polymeras are being controlled by them.
Newton's three laws of motion are examples of laws in physical science. A scientific law states what always happens but not why it happens. Scientific theories answer “why” questions.
The inheritance of mitochondrial DNA (mtDNA) is matrilineal, it means that an organism inherits the mtDNA from its mother
Explanation:
The phenomenon of matrilineal inheritance has deep genetic implications since it enables the study of phylogenetic lineages of the species (or among populations within the same species) by analyzing mitochondrial inheritance.
