Purple loosestrife, Lythrum salicaria, is a beautiful, long-stemmed wetlands species brought to the United States from Europe as

an ornamental plant. In the United States, it has no predators and crowds out cattails, Typha latifolia, another wetlands plant that's a valuable resource for many species. Purple loosestrife is an example of:

Answer:

an introduced species.

Explanation:

An introduced species, often referred to as exotic species or invasive species, is term that describes species of either plants or animals that are not native to the place ore area in which they are being introduced, either as a result of accident or deliberate movement by human activity or external factors.

Common examples of animals that are introduced species are:

gypsy moth in eastern North America, the zebra mussel and alewife in the Great Lakes, the Canada goose and gray squirrel in Europe etc.

Notable example of introduced species of plants are:

the kudzu vine, Andean pampas grass, and yellow starthistle.

Hence, Purple loosestrife, Lythrum salicaria, being native to Europe, and taken to United States, is considered to an introduced specie.

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.
