They are made of the same material, a number of substances, common to all, which show a unit of composition.
Answer:
The correct answer is Internal receptor binding.
Explanation:
Steroid hormones are derived from cholesterol. There are varios steriod hormone present inside our body such as Testosterone,glucocorticoid, mineralocortocoid, coticosterone etc.
Steroid hormone are hydrophobic in nature as a result they can cross the plasma membrane and binds to the receptor present in either nucleus or cytoplasm.
After binding to the rceceptor the receptor hormone complex interract with specific DNA sequence known as steroid hormone responsive element which further leads to the transcription of that DNA resulting in the formtion of mRNA that further enters into the translation process to synthesize specific protein associated with the functioning of that hormone .
Answer:
Insects use sound to communicate with other insects, to navigate, and to hear the sounds of a predator approaching.
Explanation:
It is believed that the tilapia fish was introduced into the mangrove system by escaping from fisheries and aquariums by accident, but this species is also used to control the population of mosquitos to prevent outbreaks of malaria and other invasive species on which they feed.
The tilapia are highly tolerant and easily adaptable to different conditions in the mangrove ecosystem and they are highly efficient predators. This often makes them more successful in the environments where they are introduced than the indigenous species, which results in disruption of the food chain.
The negative human impact on mangroves disrupts the balance in the mangrove ecosystems, weakening the populations of different species that originate from mangrove forests. This leaves more space and resources to be exploited by the tilapia.
The strategies to control tilapia in mangrove ecosystems focus on restoring the habitat and strengthening the populations of indigenous species while decreasing the numbers of tilapia.
The species can be eradicated by selective overfishing of the species or by introducing another species into the habitat which is a natural enemy of the tilapia.
em no entiendo esa pregunta creo que por ser mas delicadas ay nose
