How are new alleles created? Occasionally, DNA mutations occur in germ cells – cells destined to become eggs or sperm. In this case, the DNA mutation is copied into every new cell of the growing embryo following fertilisation. ... If the mutation affects a gene, it will result in a new version of that gene – a new allele.
Answer:DNA is the hereditary molecule that determines hair color in humans, However, the DNA molecule itself is colorless
Explanation:
Hello!
One of the most basic examples of relative dating, specifically in this case, would be the law of superposition. This simply states that out of many layers of rock, the oldest would be at the bottom and the youngest on top, so therefore the age of the fossils inside the rock would also increase when going down the layers. Therefore, we see that layer a is the oldest, and layer g is the youngest.
This disproves the first answer choice - the fossils in layer g are the youngest, not the oldest. Now, when comparing Layer F and D, we see that the rock layer F is above layer D. This means that layer F is younger than layer D (and same for the fossils in those respective layers). The third choice is incorrect as layer A would be older than F as it is beneath layer F.
Therefore, this means your second choice, or the fossils in layer F are newer than the fossils in layer D, is correct.
Hope this helps!
Explanation:
This research could help determine how efficient energy and matter transfer is through the ecosystem. Currently, it is known that this transfer is very inefficient with a mere 10% energy transfer captured in biomass from one trophic level to another. Most of the energy is lost to the environment mainly as heat energy.
It is, therefore, critical that research determines ways of drastically enhance this efficiency so as to be able to colonise Mars. It will be required that whatever humans grow/rear on Mars in small modified fields translate into a high transfer of energy when consumed by humans. This makes it tenable to sustain humans on the distant planet.
