Answer:
Oil
Explanation:
Since, unlike oil, source like wind, solar, water etc. come naturally we don't and can't replace them but when the viscosity in oil has been used up it must be change to allow the proper functioning of the machine.
Answer:
Homologous pairs separate in first round of meiosis or meiosis 1
However,
sister chromatids separate in second round of meiosis or meiosis 2.
Those reproductive cells are called gametes
Answer: 50% ErWw (wild-type traits) and 50% rrww (red eyes, white-banded wings)
To solve this, we need to analyze step by step all the data they give us.
First, they told you about two homozygous traits that are recessive in this kind of animal, Red eyes and withe-banded wings.
We'll assign the names rr and ww (lower because they are recessive)
You know the dominant traits are wild type and all are in the same chromosome.
EE will be normal eyes, and WW will be normal wings.
If you cross this F0, rrww x EERR all the offspring are ErWw.
Crossing F1 with red eyes, with-banded wing you have to draw a Punnte square with ErWw x rrww and the ofsspring posibilities you'll find are 50% ErWw (wild-type traits) and 50% rrww (red eyes, white-banded wings)
