A frame shift mutation will occur.

This the type of gene mutation arises when the normal sequence of codons is disrupted by the insertion or deletion of one or more nucleotides, provided the number of nucleotides is added or removed is not a multiple of three. For instance, if just one nucleotide is added, then all of the codons including and after the mutation will have disrupted reading frame. This can result in  the inclusion of many incorrect amino acids into the protein.

Each of the following relates to an aspect of evolution by natural selection. Explain the following. ii. Natural selection and t
dlinn [17]

         The first one, ii. Natural selection and the formation of inseticide resistant insects or antibiotic resistant bacteria.

          This can be explained in very simple way. As we all know, natural selection works in a way that only that adapted living beings are going to survive through a specific environment, whether it's because they can grab their food without too much work, or even that they can adapt to the weather. When we use inseticide, we are killing lots of non-resistant insects, and what's left are those that are resistant to this inseticide, and they'll reproduce again, and again we'll go through the same process, but remember, this insect is now stronger and more resistant that before.

            The second case, iii. speciation and isolation give three examples how it may occur.

            Well. the allopatric speciation and isolation will happen when theres a geographic barrier between one species. This one then is divided into two diffent habitats, but what can divide than could be a mountain, a tree, a river, a rock, anything. And this could be too called as a geographic isolation, because in this new environment, species are going to develop in a different way.

What should be your response as you approach a roundabout?
BigorU [14]
<span>The correct answer is B) choose the correct lane. It is always important when driving to ensure you are in the correct lane, but in roundabouts, it is essential to the traffic flow. Choice A is not correct because roundabouts are designed to slow down traffic and you need to be paying attention to what is going on and slowing down before you enter. Choice C is not correct because you do not have the right-of-way; the traffic already in the roundabout does and you would need to yield to them. Choice D is not correct because choices A and C are not correct.</span>
