If you breathed in a lot of chlorine at the pool, which of your cells would be affected? If an embryo were exposed to chlorine, which of his cells would be affected?​

Answers

Answer:

I HATE KEYONNN\

Explanation:

If a lot of chlorine is breathed in, then it would harm the lungs' cells, especially the cells of the airways, the pseudostratified epithelial cells. It harms the different organs of developing embryos as it depends on the mother.

What is breathing?

Breathing is the process of taking the oxygen inside the lungs from the atmosphere and releasing the carbon dioxide into the atmosphere. If a large amount of chlorine is taken, it will affect the cells in the airways.

Long-term inhalation of such gases causes lung problems such as acute lung disorder, asthma, pulmonary pneumonia, and so on. If such a condition arises, then it would be very difficult to provide proper oxygen to the body, and many other cellular activities would be affected.

In the case of developing embryos, it depends on the maternal supply. If the maternal blood is toxicated with chlorine, then it will supply the baby, and the developing baby organs will be affected. There are many disorders such as improper development of the brain, lungs, bones, etc. It will affect the embryo's cognitive capacity too.

Hence, a lot of chlorine affects the lungs the most when breathed.

Some students investigated the effect of light intensity on the rate of photosynthesis.
They used the apparatus shown in Figure 1.

Figure 1
The students:
- placed the lamp 10 cm from the pondweed
- counted the number of bubbles of gas released from the pondweed in 1 minute
- repeated this for different distances between the lamp and the pondweed.
The lamp gives out heat as well as light.


What could the students do to make sure that heat from the lamp did not affect the rate of photosynthesis?

Answers

The effect of light intensity on the photosynthesis rate using an aquatic organism. The effect of light intensity on photosynthesis can be investigated in water plants. Use Cabomba or Elodea, which are sold in aquarium shops. The plants will release bubbles of oxygen – a product of photosynthesis

The student can do a couple of things to make sure that the heat from the lamp did not affect the rate of photosynthesis. These include:

Using a heat screen that light can pass through easily.Using Light Emission Diode in the place of the bulb.Using low energy bulb that will generate very little to no heat.Adding a water bath will ensure that the heat is absorbed by the water in the bath instead of heating the water in the test tube directly.

Using any of the above will greatly minimize or totally eliminate the heat that will get to the plant and hence, will have no effect on the rate of photosynthesis.

What do the phase changes (condensation, evaporation, crystallization) in the water cycle have in common?

Answers

They involve the transfer of energy from the changes in state

Change in thermal energy from the Sun is the common factor during the phase changes ( condensation, evaporation, crystallization) in the water cycle.

What is Water Cycle ?

Water cycle is the continuous movement of water between Earth and atmosphere. It is also known as Hydrological cycle. Water Cycle occurs in three phases i.e. Solid , Liquid and Gas. This cycle never stops, it doesn't have a beginning or an end. It's like a big circle.

Liquid water evaporates into water vapour which condense to form cloud and precipitates back to earth in the form of rain or snow. It is a simple circular cycle of evaporation, condensation and precipitation.

Water vapour is the primary form of atmospheric moisture. Its storage is small, water vapour is extremely important in forming the moisture supply for dew, frost, fog,etc.

There are Five parts of the water cycle. They are

1. Evaporation

2. Transpiration

3. Condensation

4. Precipitation

5. Runoff.

Thus, change in thermal energy from the Sun is the common factor during the phase changes ( condensation, evaporation, crystallization) in the water cycle.
