Concerned about the exposure of children to chlorine, staff running a public pool measure the exact concentration of the chlorine currently in the pool water. however, assuming the amount of water in the pool is unchanging, to accurately determine the dose of chlorine exposure, the staff must also know

The staff must also know that for how long the child is in the pool.

Chlorine is the number one contaminant in drinking water. While the chemical is supplemented as a source to clean water and eradicate the harmful microorganisms and other waterborne pathogens, however, it exhibits some kinds of harmful effects as well.

It has been found that drinking and long-term exposure to chlorinated water can possibly enhance the threats of asthmatic attacks mainly in children who do not exhibit bettered airway systems. In case, if chlorinated water is exposed to the skin for a longer duration, it can also result in burning and irritation of the skin.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
