What are some possible consequences of a mutation? Give a specific example for each consequence you list.
Tju [1.3M]
Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations<span> occur in non-reproductive cells and won't be passed onto offspring. For example, the golden color on half of this Red Delicious apple was caused by a somatic mutation. Its seeds will not carry the mutation.
</span>

A single germ line mutation can have a range of effects:

<span><span>No change occurs in phenotype.
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span><span>Small change occurs in phenotype.
A single mutation caused this cat's ears to curl backwards slightly.</span><span>Big change occurs in phenotype.
Some really important phenotypic changes, like DDT resistance in insects are sometimes caused by single mutations. A single mutation can also have strong negative effects for the organism. Mutations that cause the death of an organism are called lethals — and it doesn't get more negative than that.</span></span>

Use Analogies Luke found a box of photos labeled 1970–1995. Each photo shows his entire extended family. No dates appear on the
suter [353]

Luke can use this information to sort the photos into four batches excluding the time period when it is not possible for all participants to be in the photo.

<h3>How are fossils dated?</h3>

The process of dating fossils is done by analyzing the sedimentary rocks that are formed around the animal for thousands of years, an analysis is also made of the atoms of the fossil of the animal, to give a certain accuracy to the research data.

With this information, we can conclude that Luke can use this information to sort the photos into four batches excluding the time period when it is not possible for all participants to be in the photo.

What type of wave interaction allows you to hear someone and not see them?
FrozenT [24]
Hello,

The answer should be "sound waves".

Reason:

If a gun go off the sound waves can go through anything to allow the person to hear for example: the sound wave can go through walls, water, and hard surface. It can also allow you to hear something but not see it therefore the answer is sound wave!

If you need anymore help feel free to ask me!

Hope this helps!
