It depends how the lights are formed

Let’s say they were Christmas lights, on older types of Christmas lights if one bulb went out the whole string of lights would go out, those were parallel, now they are usually wired in series, so if one light went out the rest of them would still light up

Explain why Neil Shubin thinks Tiktaalik says something about our own bodies? (in other words – why the Inner Fish title for the

Sophie [7]

Answer:

Neil Shubin bases his argument that the anatomy of Tiktaalik is relevant to that of humans by discussing specific features of the anatomy of Tiktaalik that vary from typical fish anatomy and correspond to features of the human body. For example, he points out that Tiktaalik has a neck that is able to bend independently of the rest of the body, unlike fish, and like all terrestrial vertebrates, including humans. Therefore, the evolutionary history of humans can be traced to an organism similar to Tiktaalik, resulting in the concept of the "inner fish."

In many animals, height is an example of a polygenic trait. Which types of natural selection can affect polygenic traits? I. dir

Marat540 [252]

The question is incomplete as it does not have the options which are:

I. only

I. and II. only

II. and III. only

I, II, and III.

Answer:

I, II, and III.

Explanation:

The mechanism of natural selection can be explained for the trait which is determined by one gene but the traits which can be determined by more than one gene like height (polygenic trait), the selection becomes very complex.

The natural selection can be explained by the phenotype produced in a population and that depends on the genes. The polygenic trait shows the variation in the population, therefore, it is impossible to predict only one mechanism and therefore all types of natural selection occurs on a population.

Thus, I, II, and III are correct.
