The movement of glucose across the cell membrane through facilitated diffusion is a form of passive transport because
Artist 52 [7]

Answer:

The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.

In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.  

Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.

How do pioneer species make ecological succession possible on an island formed from a volcanic eruptions
SIZIF [17.4K]

Answer:

The correct option is <em>3. they break down rock into soil in which plants can grow</em>

Explanation:

When a disaster is such huge that even the soil and organic matter get removed from the place, then the succession that will occur in such kind of place will be termed as primary succession. For example, a volcanic eruption or an earthquake.

On the other hand, if after a disaster some of the organic matter remains on the land, then the succession that will occur will be termed as secondary succession. E.g a succession after fire

In primary succession, the pioneer species will be plants that require less soil such as the lichens. The lichens will break down the rocks into the soil and eventually new species of plants will start to grow on the land.

Which of the following biomolecules is best represented by this formula?
Alona [7]

Answer:

The correct answer is option D. "lipid".

Explanation:

Lipids, known also as fats or oils, are organic compounds that are insoluble in water and are made up of carbon, hydrogen, and oxygen. The formula of this question shows a biomolecule that is made up of this three atoms, and even though carbohydrate are made up of this three atoms as well, we can determine that it belongs to a lipid because it contains many more hydrogen atoms than oxygen atoms. Other characteristic of lipids is their long chains of carbon and hydrogen atoms, which are represented by the lines shown in blue. I attached the missing formula.
