Answer:

glucose

Explanation:

Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot.

In the given images, The<em> left cylindrical is showing gas phase while the right cylindrical is showing a solid phase.</em>

The process of conversion of gas into solid is called deposition. Deposition process takes place when atoms lose their energy and have high kinetic energy so they directly convert into solid and not into liquid.

Hence, the correct option is "C".

Give an example of spinal reflex and explain how the nervous system functions in this reflex action
Bad White [126]

The patellar reflex is the most common example or a spinal reflex. When the knee is tapped, the nerve that will receives this stimulus sends an impulse to the spinal cord and relay it to the motor nerve. This sources the quadriceps muscle at the front of the thigh to contract and twitch up the leg. This reflex contains simply two nerves and one synapse.

What kind of model is a globe and what are its limits
tester [92]

A model of a globe is a physical model. The limits are that the solar system is too big to be seen all at once. From the Tennessee science textbook, "Many years ago, scientists thought that Earth was the center of the universe and the sky was a blanket that covered the planet. Later through the observation, it was discovered that the objects you see in the sky are the sun, the moon ,stars, and other planets. This new model explained the solar system differently.

Are plants able to do cellular respiration? Why or why not?
Maru [420]

Both plants and animals are able to do cellular respiration. Plants convert nutrients from the soil into usable energy.

This is the plant cellular respiration formula:

oxygen + glucose -> carbon dioxide + water + heat energy

Hope this helped! Let me know if there is anything I need to clarify or explain more in depth
