I'm assuming you meant pool instead of poolon, i'll take it as a grammatical error. Anyhow, the water in a pool on sunny days tend to have less chlorination then on regular days. This is because chlorine forms hypochlorite ions in the water, and these are broken down by the ultraviolet light from the sun. Rainy or shiny, the weather is always affecting the chemistry in your pool.

Now, if you want to get more complicated into it, you can add a stabilizer into the pool. The common one safely used in pools is cyanuric acid. This almost completley prevents all de-chloronification.

I hope this information was of any use to you.

The bones in the wings of birds and bats are _______ because they derived from a _______ ancestor, while the wings are _______ t

dolphi86 [110]

The answer is: homologous; common; homoplastic.

The bones in the wings of birds and bats are homologous because they derived from a common ancestor, while the wings are homoplastic traits. Homologous structures are similar structures shared by different groups and that are derived from a common ancestor. The similar anatomy of bones in the wings of birds and bats is inherited from a common ancestor of tetrapods (to which birds and bats belong). However, wings are not inherited from the common ancestor of birds and bats. Therefore, wins are homoplastic traits (analogous structures) because they have similar function but they are not inherited from the common ancentor.

Kepler's second law using Mercury , which has an orbital period of about 0.24 and a semimajor axis of about 0.387 . Explain your

krok68 [10]

As the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.

<h3>What is Kepler's second law?</h3>

Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the Sun.

This law exaplains the speed of planets around the sun, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.

From the findings, the astronomical unit of the Mercury is 0.387 and the orbital period is 0.24 year.

$T \propto a^{3/2}$

$T = ka^{3/2}\\\\k = \frac{T}{a^{3/2}}$

From the equation above, as the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.
