Answer:
b. True
Explanation:
Behavioral ecology is a science that studies animal behavior, considering its evolutionary and ecological bases, in which through experiments it seeks ways to show the evolutionary / adaptive causes of behaviors. Ecoetology deals with functional questions about behavior, how a behavioral pattern contributes to the survival chances of an animal or group of animals and their reproductive success. In addition, behavioral ecology is a meeting point for the study of behavior, ecology and evolution, in which ecology is the stage on which the animal must perform its behavior, and evolution in which organisms will be selected for having higher behaviors. success.
For this reason, we can conclude that the study of behavioral evolution, emphasizing the role of ecological factors as agents of natural selection, is known as behavioral ecology.
Answer:
Background
During the course of a bacterial infection, the rapid identification of the causative agent(s) is necessary for the determination of effective treatment options. We have developed a method based on a modified broad-range PCR and an oligonucleotide microarray for the simultaneous detection and identification of 12 bacterial pathogens at the species level. The broad-range PCR primer mixture was designed using conserved regions of the bacterial topoisomerase genes gyrB and parE. The primer design allowed the use of a novel DNA amplification method, which produced labeled, single-stranded DNA suitable for microarray hybridization. The probes on the microarray were designed from the alignments of species- or genus-specific variable regions of the gyrB and parE genes flanked by the primers. We included mecA-specific primers and probes in the same assay to indicate the presence of methicillin resistance in the bacterial species. The feasibility of this assay in routine diagnostic testing was evaluated using 146 blood culture positive and 40 blood culture negative samples.
Explanation:
Results
Comparison of our results with those of a conventional culture-based method revealed a sensitivity of 96% (initial sensitivity of 82%) and specificity of 98%. Furthermore, only one cross-reaction was observed upon investigating 102 culture isolates from 70 untargeted bacteria. The total assay time was only three hours, including the time required for the DNA extraction, PCR and microarray steps in sequence.
Answer:
D) All visible light waves except red are absorbed by the ball
Explanation:
When we see things that are a certain color, it is because the object is absorbing all the visible light waves except the one we are seeing. In this case, the ball is absorbing every color on the visible spectrum except for red. Red is being reflected back towards the child's eye which is why the child sees the ball as red.

Microscopes have been used for centuries in order to see specimen scientists cannot see with their unaided eye. Antón VanLeeonhoeuk is given credit for designing the first lenses for microscopes in the 16th century. He looked at “animacules” which we would now call bacteria and protists. Robert Hooke first coined the term cell, as he looked at cork and thought it looked like cells that monks slept in. Improvements were made in the following centuries, and Ernest Leintz in the 1800s creates a way to have differing magnification lenses on one microscope. Continuing into the 1900s and 2000s there are now electron scanning microscopes, ultraviolet microscopes, atomic force microscopes, and electron tunneling microscopes—all which allow scientists to have better resolution and to see smaller and smaller things. Microscope technology will continue to improve as scientists discover more ways to magnify the microscopic world.
