Answer:
They are called Trace elements
they function as catalysts for enzymatic reactions
in some oxidation-reduction reactions (Cu) for some metabolic reactions to for ATPs synthesis,and
also as oxygen carrying elements in Hb and myoglobin muscles e,g(Fe)
Explanation:
Basically Trace elements are group of minerals in small quantity in living organisms.Their functions may be important or essential to the organisms,or needed in small amounts non essentials.
Example of these elements are Fe,Zn,Se,Cu,I,Mn Mb. etc
They are also involved in prevention of some diseases .Generally when they are consumed in large amounts they are toxic to living cells.
others like aluminum, cadmium, mercury lead may beneficial to living organisms,but there role has not yet be verified.
The proprioceptors
The proprioceptors such as muscle
spindle and golgi tendon organ are sensors located in the limbs. The proprioceptors
give information about muscle length, muscle tension and joint angle which is coordinated
to provide information about the limb’s position in space.
Answer:
Answer is option (3).
"Blowing your nose may cause bruising and edema."
Explanation:
Nasal surgeries like septoplasty, rhinoplasty, sinus surgery, etc are usually performed to improve breathing, repair nasal injuries, correct deformities
, change the size or shape of the nose, correct sinus problems, etc.
After the surgery, the patient must follow certain instructions for at least 10 days. The instructions are;
- Avoid strenuous activity for at least two weeks as it may cause bleeding or increase swelling in the operated area.
- Avoid nose blowing after surgery as it may cause bleeding and spreading of infection into the eye. When the patient blows the nose after nasal surgery, the sinus pressure increases and results in increased pressure on the operative site which may cause bruising and edema. But it does not increase intracranial pressure or cause a fracture or decrease oxygen availability.
- Apply nasal saline sprays on each nostril frequently as it keeps the nose clean and clears all debris (dried blood) and maintains moisture in the nose. Also, the clearing of nasal passage results in increased oxygenation.
- Use nasal decongestants to reduce the swelling in the nose.
Answer:
The sea affects the climate of a place. Coastal areas are cooler and wetter than inland areas. Clouds form when warm air from inland areas meets cool air from the sea. In the summer, temperatures can be very hot and dry as moisture from the sea evaporates before it reaches the centre of the land mass.
