The lungs deliver a regular supply of oxygen to the blood, which is in turn circulated to most all the cells of the body. At the

same time oxygen is consumed during aerobic cellular respiration within these cells. This implies that ________.

Answer:

The correct answer would be - oxygen will passively diffuse into the cells.

Explanation:

As the oxygen molecules are very small and has no polarity or no charge they show the passive diffusion through the plasma membrane from the higher concentration to lower concentration inside the cell.

In the lungs the oxygen diffuses out the air sacs into the blood as the air sacs of lungs have higher concentration of oxygen than the blood stream and as the various cells perform the aerobic cellular respiration the concentration of the oxygen inside of the cell become low to the blood so oxygen diffuses into cells.

Thus, the correct answer is - oxygen will passively diffuse into the cells.

Answer:  Layers of the Sun are : Core, Radiative zone and convection zone

(all three constitutes inner layers), photosphere, chromosphere, transition region and corona (all four constitutes outer layer).

Explanation:

The Sun is made from hydrogen and helium.

The Sun is consists of inner and outer layer. Inner layer constitutes main part of the Sun and is further classified into 3 parts -  Core, Radiative zone and convection zone .

The atmosphere of Sun forms it's outer layer which comprises 4 parts - photosphere, chromosphere, transition region and corona.

Light and heat radiated from Sun is energy that is released from Sun as part of nuclear reaction that takes part in it's middle part know as core.

Energy from core moves as electromagnetic radiation towards radiative zone, from where is moves out further by photon carriers.

From radiative zone energy moves towards convection zone. This zone is the outer most of zone of Sun's inner layer and it is here where light energy coming from core layer is converted into light form.

Umnica [9.8K]

Answer:

The correct option is B  

Explanation:

The alpha and beta-gamma subunits both can bind to target  proteins. Once a G protein becomes active, its alpha subunit and beta-gamma dimer both have the ability to pass on messages in the cell via connecting or binding with other membrane proteins that are involved in the transduction of signals. In this light, B is the best option.
