This first step to protecting this endangered species of snail is to preserve its existing habitat. This means that steps need to be taken to ensure that <span>Chittenango Falls state park continues to offer a refuge to this snail, and that steps are taken to improve the water quality in the park. A scientific study can be run to identify the pollutants and their concentrations that are having a negative effect on the snail species. For this, water quality testing can be conducted to first identify any pollutants. Once suspect pollutants are identified, ecotoxicology tests can be run to identify concentrations of the pollutants that have an effect on the snail. Both acute (short term) and chronic (long term) tests would have to be conducted, looking at mortality as well as sub-acute end points such as growth and reproduction. Once concentrations of pollutants are identified that would negatively affect the snail, we can call these 'water quality guidelines' that we would need to keep water quality within. We can then identify sources of these pollutants upstream, and take steps to reduce the pollution at source, by forcing factories to treat their water more rigorously or changing upstream land use. Finally, what can also be considered is introducing the snail species to new habitat within the State of New York. We must be careful here though as the actions of man have spread invasive species globally. </span>
Answer:
Anterior lobe
Explanation:
The pituitary gland is made up of two distinct lobes: the anterior lobe and the posterior lobe. The anterior lobe secretes as many as seven different hormones. Some of the hormones secreted by anterior lobe are namely adrenocorticotrophic hormone, prolactin, gonadotropins, melanocyte-stimulating hormone, and thyroid-stimulating hormone. The posterior lobe releases only oxytocin and vasopressin in the bloodstream. These hormones are not produced by the posterior lobe but are only stored and released by it.
Answer:
Todos los grupos de organismos vivos comparten varias características o funciones clave: orden, sensibilidad o respuesta a estímulos, reproducción, adaptación, crecimiento y desarrollo, regulación, homeostasis y procesamiento de energía. Cuando se ven juntas, estas ocho características sirven para definir la vida.
Explanation:
Answer:
DNA never leaves the nucleus; RNA is in the nucleus and in the cytoplasm.
Explanation:
DNA and RNA differ from each other with respect to their structure, function, and location. DNA is always present in the nucleus and never leaves the nucleus.
DNA replication and transcription also occur in the nucleus to form DNA and RNA respectively.
On the other hand, RNA is present in both the nucleus and cytoplasm. The mRNA leaves the nucleus and enters the cytoplasm to serve as a template in protein synthesis. The rRNA and tRNA are also present in the cytoplasm.
The answer is because the cell membrane is pressed against the cell wall.
