Answer:
Models are used to simulate reality and make predictions. The major limitation of models is that they are 'idealizations' or 'simplification' of reality and thus cannot possibly replace reality. A number of assumptions are made during modeling and this causes differences between model and reality.
Answer:
Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
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.
Answer;
Ovaries, Fallopian tubes
An ovum bursts from one of a woman's Ovaries & is drawn into one of the two Fallopian tubes.
Explanation;
-Follicles develop inside - and eventually rupture, being released outside - the ovaries. It is soon swept into the nearest Fallopian tube by the finger-like projections that form the end of the tube, where it will hopefully be fertilized. At ovulation, the follicle ruptures and the egg breaks through the surface of the ovary.
-Sperm can penetrate the egg beginning embryonic development, if it successfully implants in the uterus you will have a pregnancy.
