Answer:

A light pole

Explanation:

A light pole does not contain any areas in which an organism could inhabit

A hydrothermal vent contain many bacterias which can survive under those conditions, similar to an abandoned mine

The Kowloon Walled City can be considered an ecosystem only because within the City there may be many areas in which an organism could inhabit

A __________________ allows hydrogen ions to flow across the inner mitochondrial membrane.
yuradex [85]

The name of the embedded protein that provides a channel for the hydrogen ions to pass through the membrane is ATP synthase.

ATP synthase is a protein that catalyzes the formation of the energy storage molecule adenosine triphosphate (ATP) using adenosine diphosphate (ADP) and inorganic phosphate (Pi). It is classified under ligases as it changes ADP by the formation of P-O bond (phosphodiester bond). ATP synthase is a molecular machine.

The overall reaction catalyzed by ATP synthase is:

ADP + Pi + 2H+(out)    ⇌      ATP + H2O + 2H+(in)

The formation of ATP from ADP and Pi is energetically unfavorable and would normally proceed in the reverse direction. In order to drive this reaction forward, ATP synthase couples ATP synthesis during cellular respiration to an electrochemical gradient created by the difference in proton (H+) concentration across the inner mitochondrial membrane in eukaryotes or the plasma membrane in bacteria. During photosynthesis in plants, ATP is synthesized by ATP synthase using a proton gradient created in the thylakoid lumen through the thylakoid membrane and into the chloroplast stroma.

Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain protei
Vlada [557]

Answer:

D

Explanation:

Intestinal cell takes in glucose against Concentration gradient (uses energy in the form of ATP) to transport glucose into cell.

In blood cell, uptake of glucose occurs down concentration gradient. Hence, its facilitated diffusion (passive transport)

Glucose is a polar molecules due to presence of polar hydrophilic - OH group, hence carrier proteins are needed to provide a hydrophilic channel for glucose to enter the cell via facilitated diffusion.

Over time, a plant pollinated by a hummingbird has developed very long, tube-like flowers. Why might the flower have adapted in
erik [133]
The flower would have adapted to allow the hummingbird to better pollinate it. I believe this to be true because it follows the process of adaptation.
