One summer you begin noticing ants in your kitchen. It starts off as just a few here and there, but pretty soon you begin notici

ng more and more appearing each day. Before long, it is apparent you have an ant infestation. While you wait for an exterminator to come to your house, you observe their behaviours. You notice that some ants seem to be congregating near crumbs, while other ants seem to avoid the crumbs and, instead, are eating the plant you have in the kitchen. You try to clear the ants away from the food, and when you do, you notice a strong, unpleasant scent. You then try to clear the ants away from the plants, and when you do, you observe no unpleasant odors. When the exterminator arrives, you ask him about these strange observances. Upon closer look at the ants, the exterminator concludes that you have an infestation of two different species, Crematogaster ashmeadi (acrobat ants) and Linepithema humile (Argentine ants). a) Propose the most probable type of speciation that occured between C. ashmeadi and L. humile. Justify your response. b) Identify one potential postzygotic isolating mechanism that reduces the fitness of the hybrid individuals.

Answer:

Sympatric speciation.

Explanation:

Sympatric speciation occurs between Crematogaster ashmeadi and Linepithema humile ants because they live on the same geographical location. Sympatric speciation is a type of speciation in which ancestral population evolve into separate species without separation of geography. Hybrid sterility is the postzygotic isolating mechanism that decreases the fitness of the hybrid individuals and helps in controlling the population of an organisms..

Alborosie
<span>For the answer to the question above, the mRNA stands for messenger RNA. The job of the messenger RNA is to copy the code from the DNA and go through a ribosome so a protein can be created.

rRNA stands or ribosomal RNA. It is essentially the ribosome and is comprised of the large and small subunit. The rRNA allows the mRNA to go through rRNA in order to create the amino acid chain.

tRNA stands for transfer RNA. tRNA brings amino acids to the coordinating codon on the mRNA and matches it to the correct codon.

As a glacier moves across the land, it pushes soil and rocks in front of it and to the sides of it. What are the hills resulting
spin [16.1K]

Answer: They are called Moraines

Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.

Glaciers constantly move on land and they do this under their own weight.

As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.

The resulting hill formed as a result of this soil movement is called a Moraine.

A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.

Please explain the difference between a frameshift mutation and a base substitution mutation.
harina [27]

Answer:

A frameshift changes every codon past it. A base substitution only changes one codon.

Explanation:

DNA is comprised of nucleotides (A, C, T, G) that make up amino acids. Every three bases is called a codon and represents an amino acid.

In a frameshift mutation, a nucleotide is either added or deleted from the sequence. This offsets the entire sequence after it because the reading frame shifts. Here's an example:

ACTGCTATCGTCATC

If another T is added in between the first and second codons, then every codon after will be changed.

ACT>T<GCTATCGTCATC

A substitution mutation is usually less severe, as it only alters one codon in the sequence. These occur when one nucleotide is replaced by another one. Here's an example:

ACTGCTATCGTCATC

Let's say the first G is replaced by a T.

ACT>T<CTATCGTCATC

As you can see, none of the other codons changed.

Typically, a frameshift mutation is considered worse than a substitution mutation.
