Answer:

This drilling enhances economy of the country but at the same time disturbs aquatic animals.

Explanation:

Due to drilling at coastline, oil should be extracted from the sea which fulfills the oil requirement of the country and valuable money can earned by exporting this oil. Due to this drilling, the habitat of aquatic animals are destroyed and no trade should be done from this coastline with other countries because the area is now only for drilling. So this plans has both positive effect on the country's economy but has negative impacts on the environment and ecosystem.

dusya [7]

Numerous antiepileptic medications, such phenytoin, have been designed to block voltage-gated sodium channels (VGSC) in neuronal membrane. In addition, multiple toxins and pharmacological modulators work by attaching to various biophysical states of the VGSC to cause their effects.  Depending on how modulatory agents act, some VGSC states are stabilized or destabilized, altering the channel's biophysical properties. The first anticonvulsant to successfully treat epileptic disorders without causing undesirable side effects such as brain drowsiness was phenytoin.

Phenytoin has been indicated to block high-frequency neuronal activity potentials from the inner vestibule of the pore, as demonstrated by electrophysiological research and site-directed mutation.

Frequency and voltage both affect phenytoin binding.

There are theories that phenytoin interferes with the late sodium current that sustains depolarizations in epilepsy by blocking non-inactivated channels.

Maslowich

Answer:

Provide information about geography

Explanation:

<em>UAVs are otherwise known as unmanned aerial vehicles or drones. They are usually remotely controlled and monitored from a screen. They can be flown over a large expanse of land to obtain geographical information such as the topography of an area,  the distance between two points, the height above sea level, and so on.</em>

<u>Except the UAVs are specially designed and equipped with extra features, they cannot be used to obtain information relating to soil nutrients, soil hydration, or information about plant health on a field. </u>

Hence, the correct answer would be option 1,

Darina [25.2K]

Answer:

white eyes and hairy body

Explanation:

Based on the scenario being described within the question it can be said that the allele combination that has the greater map distance would be white eyes and hairy body . This is mainly due to the fact that this combination have four map units between them, when compared to the other same chromosome combinations which, the next runner up would be red eyes and normal body with two-units between them.
