The correct structure is shown below,

According to rules the longest carbon chain is selected, and numbering is started from side nearer to carbonyl group. As the parent name goes to ketone, so among alkyne and halogen second priority is given to alkyne and 3rd to halogen

So, the name shoul carry following words,

3- one (for ketone)

5-yne (for Alkyne)

7-Bromo (for Halogen)

Result:
So the structure is as follow,

If there are 32 sister chromatids in a normal somatic cell, what is the haploid number for that cell?

malfutka [58]

Answer:

The answer is 16.

Explanation:

Somatic cells include all the cells in the body except for the reproductive cells. Haploid cells are used to represent the reproductive cells which have half the chromosome as the somatic cells. So if there are 32 sister chromatids in a somatic cell, which means there are 16 chromosomes, then the haploid number for it is 16 chromatids. I hope this answer helps.

How did Darwin arrive at the idea about species variation

jeyben [28]

Answer:

We can see some of the most important patterns Darwin noticed in distribution of organisms by looking at his observations of the Galápagos Islands off the coast of Ecuador. Darwin found that nearby islands in the Galápagos had similar but nonidentical species of finches living on them.
