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.
As it gets colder, the molecules get less dense which causes it to get smaller.
The answer is omnivores.All these species are omnivores. Omnivores are animals that eat both either animals and plants. Some species of cricket are known to eat some plant materials and small insects. Robin eats mostly fruits and berries, but also worms and insects. Raccoon eats nuts, berries, fruits, fish, frogs, insect, mice, rabbits and other small animals.All this classifies them as omnivores.
Thats a hypothesis another word for it is a theory but the scientific term is a hypothesis, hope this helps love
Answer:
his continental drift
Explanation:
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. ... Wegener suggested that these creatures were alive in warm climate zones and that the fossils and coal later had drifted to new locations on the continents.
