Answer:

D) heat.

Explanation:

"Thermal", as defined by Oxford Languages, is <em>relating to heat</em>.  In the case of thermal energy therefore, it is simply referring to <em>how energy would react to either the heat, or the lack thereof.</em>

Use the principles of diffusion to explain why oxygen molecules in the tissues of the lung go into the blood
Keith_Richards [23]

Answer:

Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.

Explanation:

Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.

Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.

Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.

Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.

Explain how the resting potential is created and maintained. (sodium potassium pump) What happens when sodium comes in and potas
MAVERICK [17]

Answer:

The resting membrane potential is created and maintained due to the difference in the total charge or ions present outside and inside of the cell. The resting membrane potential depolarize if sodium come in and and potassium leaves the cell.

Explanation:

The resting membrane is maintained and created by the distribution of potassium and sodium ions. The membrane potential of a resting cell is -70mV (negative) because more sodium ions is present outside the cell than the potassium ions present inside the cell.

When the sodium ions enter inside the cell and potassium ions move outside the cell, the inside of the cell becomes more positive as compared to the outside and the membrane potential changes from -70 mV to +30 mV. The cells will depolarize due to the accumulation of sodium ions inside the cell.

Item 2 In which sphere does a dolphin swim?
Romashka-Z-Leto [24]

Hydrosphere

Explanation:

  • The dolphin swims in the hydrosphere.
  • The hydropshere is the region occupied by water on the earth surface.
  • They are the oceans, lakes, rivers, glaciers e.t.c
  • The hydrosphere makes up 70% the total surface area on earth.
  • Ocean occupies a whooping 95% of all.
  • The hydrosphere is able to support aquatic life and this is why the dolphin with its streamlined body swims in this sphere.
