The correct answer among the choices listed above is option C. It is important that a plant's phloem extends into its leaves because the phloem <span>collects the sugars made during photosynthesis and carries them around the plant. Hope this answers the question.</span>
The answer is A.) Troposphere, Stratosphere, Mesosphere, Thermosphere
Answer:
The cell was first discovered by Robert Hooke in 1665 using a microscope. The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s.
Histotoxic hypoxia, which happens whenever body cells are not able to utilize oxygen while receiving sufficient amounts, is typically caused by metabolic toxins like cyanide.
What is hypoxia?
- Hypoxia is a state in which there is insufficient oxygen reaching the tissues throughout the system or a specific area of the body.
- Although fluctuations in arterial concentrations of oxygen are frequently associated with clinical conditions, they can also occur naturally during severe physical activity or hypoventilation training.
When does Histotoxic hypoxia occur?
When the supply of gas entering the cell is adequate, but the cells are unable to utilize the oxygen properly due to deactivated oxidative phosphorylation enzymes, histotoxic hypoxia develops. Ingestion of cyanide may result in this.
