Hello.
sometimes water just produces bubbles even without any plant in it! If the water is under pressure in the water pipes before you open the tap, then the water has lots of air dissolved in it and this will come out of solution when you leave it to stand. If you boil water, it will get rid of the air.
The gas bubbles generated during photosynthesis by aquatic plants produce distinctive sound pulses when leaving the plants. In photosynthesis of submerse water plants Oxygen emission occurs in form of bubbles which are released from the stomata or small openings caused by injuries.
Have a nice day
Frog's heart<span> has one ventricle, while humans have 2, hence deoxygenated blood from body mixes with the oxygenated blood coming from lungs.

Answer:
loose connective tissue
Explanation:
A layer of tissue lies immediately below the dermis of vertebrate skin. It is often referred to as subcutaneous tissue. The hypodermis consists primarily of loose connective tissue. It contains larger blood vessels and nerves than those found in the dermis.
i hope this helps! :)
Answer:
All results for the experimental groups involving wing surgery would be invalid.
Explanation:
The experimental group involving wing surgery would not lead to correct results because it is a direct parameter that is impaired. This has been already clearly stated in the question that these flies are prone to attack compared to those which are not treated. There could be several reasons for that such as: (1) the reattachment would not have been successful, and/or (2) the flies' health (fitness) status would have been compromised.
On the other hand, it is not correct that all experimental groups will lead to incorrect results because the untreated flies were not attacked (or less attacked). Similarly, there is no condition given for houseflies rather only zonosemata flies. So 3rd option is also not possible. Finally, the reliability of the results would definitely change because the treated flies would be more attacked and lead to a clear difference in results.
