Answer:

The letter D is the right answer

Explanation:

Even in this century, the Earth's temperature will be 1.5ºC higher than in the 19th century, when the British invested in carbon-burning processes that had recently created the industry.

Scientists' predictions for the future of the Earth, in the face of climate change, include more intense droughts and cyclones, more acidic oceans, extinction of species that guarantee ecological balance. This is because due to the increase in the average air temperature on our planet, the polar caps and ice at the poles will melt at an ever increasing speed, causing the increase in ocean levels, causing flooding and destroying part of our biodiversity, besides In addition, evaporation will increase by drying up rivers and causing us serious problems.

The increase in salinity, however, is not a result of rising earth temperatures.

D because just because of all the other effects it has no salt effect on the ocean

An inhibitory stimulus has occurred. B. Chemically gated potassium channels have opened. C. Excessive potassium has diffused out

andrezito [222]

Given question is incomplete. Complete question has been attached.

Answer:

C. Excessive potassium has diffused out causing hyperpolarization.

Explanation:

The nerve action potential can be divided into following stages:

Stimulus is detected by the cell in resting stage.
Sodium channels in the membrane open from where influx of sodium ions occur which is called depolarization
After a while, sodium channels close and potassium channels open from where efflux of potassium ions occur which is called repolarization.
The membrane potential further lowers due to continous efflux of potassium ions which is called hyperpolarization.
After a while potassium channels close and membrane returns to its resting stage.

In the given figure, stage 4 depicts hyperpolarization because the membrane potential has dropped to the lowest point below -70mV. Hence, option C is correct.

The white blood cells primarily responsible for adaptive immunity are

leonid [27]

Answer:

T and B cells.

Explanation:

Adaptive immunity is the kind of immunity that you acquire after exposure to an antigen (pathogen or vaccine), it involves memory in order to facilitate a quick response if there's a reinfection with the same pathogen.<em> T cells are responsible for the cell-mediated response while the B cells are responsible for the humoral response.</em> Both of these cells are specific to the pathogen's structure, therefore they can kill it directly.

I hope you find this information useful and interesting! Good luck!
