Hi there!
Most native species that evolved with their habitat also have an array of natural predators and parasites to keep the population in check. The exception to this is invasive species. Such species are usually introduced into a habitat artificially and lack the natural predators and parasites present in their original home.
Therefore, the type of species that normally reproduces quickly with little to no predators to control the population are invasive species.
Answer:
A sequence is a section of DNA that is required to make a protein.
Explanation:
The definition of a point mutation states that a mutations is a point mutation if it affects only one or few nucleotides in the DNA product. We have that DNA is read in frames of 3 nucleotides. If the starting point of one frame is changed, then all frames are changed because the frames are grouped by 3 nucleotides. We have that frameshift mutations not point mutations because a shift in the reading frame affects how the rest of the DNA is read. This is the case for insertion and deletion of a nucleotide; it changes the number of nucleotides and shifts the reading frame by 1. A missense mutation is a point mutation though; it involves substituting a nucleotide with a wrong one. It involves an error only in one place and it does not change the reading frame so it affects only one nucleotide.
Answer:
B. Does the organism perform photosynthesis?
Explanation:
Plants are autotrophic, that is they are capable of making their own food. They carry out photosynthesis, converting light energy to chemical energy which they use.
Fungi on the other hand are heterotrophic, they do not make their own food. They do not carry out photosynthesis.
Hence, ability to perform photosynthesis is an attribute that'll differentiate between fungi and plants.
The antibodies to the HIV virus may take up to three months to appear in the blood of the infected person.
Therefore, the second blood test is necessary three months after a person thinks that he/she has been exposed to HIV to check the presence of these antibodies and confirm whether the person is infected or not.
