Answer:
Coral reef bleaching
Explanation:
<em>The correct answer would be coral bleaching.</em>
Coral bleaching is generally define as the change in color that results from the expulsion of green symbiotic algae from the tissues of the coral.
The expulsion of symbiotic algae from the tissue of coral is usually caused by a change in stressor factors of ocean water such as light, temperature, nutrient.
<u>When the temperature of ocean water increases as a result of global warming, the vibrant color of corals may be lost because the change in stress condition usually leads to the degradation of the algal pigments or outright expulsion of the symbiotic algae from the tissue of the corals. When this happens, it leaves the coral tissues completely white and they are said to have been bleached.</u>
In vascular plant, Xylem is one of the two tissue involve in transport water from roots to stems and leaves and also transports nutrients.
Two types of cells of this tissue are tracheids and vessel elements which are involved in transport.
<h3>What is the function of xylem ?</h3>
Xylem and phloem are known are two major vascular tissue.
Xylem tissue involve in transport of water and some nutrients from the roots to the leaves.
Phloem tissue involve transport of sucrose and other nutrients throughout the plant.
The passive transport called xylem sap occur through a long tube xylem cells.
The phenomenon where the xylem sap allow the flow upwards against gravity is called capillary action.

Answer:
b) 7 degrees
Explanation:
The brain scanning techniques like CT and MRI have the reference lines like IOML or Infraorbitomeatal line and OML or Orbitomeatal line. These lines act as the standard reference during the CT techniques based on X-Rays.
The OML line passes through the centre of the external auditory meatus and the canthus of the eye whereas the line drawn between the external acoustic meatus to the infraorbital margin. These lines are used to adjust the positions of the cranium or the skull during the Radio-imaging process. The difference formed between these lines approximately lies between 7-8 degrees.
Thus, 7 degrees is the correct answer.
