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.
During high-intensity exercise, muscles primarily get their energy from the carbohydrates we intake. These biomolecules are what the body uses to store and produce energy for each activity we do. These substances are very important to be part of our diet.
Answer: Option E
Explanation:
Most of all poriferans/ sponges are suspension or filter feeders. Suspension feeders are organisms that each food materials which are suspended in their environment ie sea water, while filter feeders filter their food source from water by drawing water containing bacteria and organic matter in through their ostia(pores). Substrate feeders at organism that live in or on their food source.
Members of the poriferans do hava an ectoderm (epidermis) and an endoderm including a non-cellular late that is present in between the two layers.
No, they do not belong to the phylum cnidaria but porifera. Cnidarians including hydra, sex anemones, jellyfish etc and these have features that different from that of the sponges e.g the presence of nematocysts in cnidarians
Sponges can reproduce both sexually and asexually. Sexually by releasing larva fertilized in the sponge into water where they float around for some days and then proceed to adhere to a solid surface and begin their growth into adults. Asexually by budding
They are multicellular, lack tissues, are animals, lack organs and are asymmetrical. These are th distinguish features of poriferans
