During Telophase 2, a nuclear envelope forms around each set of new chromosomes. In this stage, cytokinesis occurs, which is responsible for producing four daughter cells each with a haploid set of chromosomes. During the crossing-over phase some chromosomes are observed to have segments that have recombined with the original parent chromosomes.   
<span>
When the phase is over, the two cells are now finally separated and their nuclear membranes are fully formed causing the meiosis cell division to be completed.</span>

Reflex action refers to the response to a stimulus, while reflex arch refers to the path taken by the reflex action.

<h3>What is the nervous system? </h3>

1. Low oxygen levels are detected by sensory receptors in the arteries.

2. An impulse is produced by sensory neurons.

3. Certain parts of the brain get an impulse from the central nervous system.

4. Motor neurons carry messages from the brain.

5. Isabel's respiration becomes more rapid.

Reflex actions are immediate, reflexive reactions to stimuli that limit bodily harm.

Therefore, it travels to the brain via the central nervous system and sends impulses via Isabel's motor neurons, which aid to speed up her breathing.

sergiy2304 [10]

Answer:

protected; increase

Explanation:

Ozone is composed of trioxygen which is highly reactive gas compared to dioxygen. Ozone layer is present in stratosphere and troposphere and protect the humans from ultraviolet radiations but it may be toxic if inhaled. Ozone can be broken down into molecular oxygen by chlorine and bromine atoms.

A hole was discovered in ozone layer in 1982 and scientist believed that it could be dangerous for human health. The compounds involved in depletion of ozone are mainly Chlorofluorocarbons (CFS) and (HFCS). Then a global agreement was signed in 1987 which leads to prohibition of use of all chemicals that are involved in depletion of ozone layer. The problem of ozone depletion is solved by the agreement and ozone hole started to recover it from 2000.

But recent reports showed that the alternative chemicals used to protect the depletion of ozone layer began to trap the heat inside the earth like greenhouse effect. Now scientists are in search of chemical that can prevent both ozone depletion as well as global warming.
