Keystone predators effect their habitat by keeping the population of animals down.
The correct answer is B, internal intercostal muscles and abdominal muscles would contract.
Exhalation is the flow of the breath out of the body. During forced exhalation, internal intercostal muscles contracts which lower the rib cage and decrease thoracic volume, while the abdominal muscles push up on the diaphragm which causes the thoracic cavity to contract.
2. High birth rate, zero death rate, high immigration, zero emigration
This is because birth rate and immigration increase population size, and death rate and emigration decrease population size, so maximizing the former and minimizing the latter are ideal
Answer:
Microarray technology is a very useful technology that allows to study the measure the expression levels of large numbers of genes simultaneously. It consists of a solid support (that can be glass, silice, or nylon), and to it are attached a lot of single stranded DNA fragments that acts like probes. By complementarity, the genes corresponding to this probes that are being expressed at some time will attach to it. Probe-target hybridization is usually detected and quantified by detection of a fluorophore compund, a silver stained, or chemiluminescence-labeled targets.
