The Miller-Urey experiment showed that simple molecules could have arisen abiotically. This chemical experiment included conditions similar to those present on the early Earth, and tested the origin of life under those conditions.
Water (H2O), methane (CH4), ammonia (NH3) and hydrogen (H2) were the chemicals used to produce the results of the experiment, the factors needed for simple life to arise. Given similar conditions on other planets, it's possible that life could arise there as well.
You can use a plotting compass or iron filings to detect a magnetic field:
1.put a piece of paper over a magnet (this stops the iron filings sticking to the magnet)
2. sprinkle iron filings onto the paper
3.gently tap the paper to spread the filings out
4.observe and record the results
Answer:
Yes, 75%
Explanation:
Since the first offspring produced between the ram and the ewe was black you can determine that both sheep have a recessive and dominant allele. Both of the parent's genotypes would be Ww, this is because they both have the white phenotype and they were able to produce a black offspring. Since both parents have a genotype of Ww the probability of a black offspring being produced is 25% and 75% for a white lamb.
