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.

Of the 200 to 400 million sperm cells released in a typical ejaculation, approximately how many do you think will reach the ovum
Travka [436]
Only 200 out of 2 000, 000 sperm cells reach the ovum. And only one (in exception to very rare cases of two) sperm cells actually participate in the process of fertilization. In comparison, an average female only produces 400 of egg cells during their lifetime, but the eggs cells are significantly larger than sperm cells.
