Why is water pollution a concern if water is continuously cycled through Earth’s systems?

Biology

blsea [12.9K]3 years ago
7 0
The Earth's Water Cycle involves Evaporation, Condensation, and Precipitation. Evaporation purifies the water resulting to the replenishment of freshwater to the Earth.

Water pollution is a concern despite of the water being continuously cycled through Earth's systems because the source of pollution is has not been removed.

Water pollution is defined as the contamination of bodies of water. Pollutants are directly or indirectly released to the bodies of water causing the water to be polluted.

Imagine: A river is filled with garbage, it is polluted. The water from the river undergoes the water cycle but since the garbage is still present in the river, the freshwater that comes from precipitation becomes polluted.

Male-patterned baldness is more common in males as the name suggest.why is this?
Ray Of Light [21]

Answer:

mark brainliest :))

Explanation:

Because baldness is a sex-linked trait.  

In other words, men are simply more likely to express the trait for baldness than women are, because they only need one set of genes for baldness, while women need two.  

If, for example, for each gene there is a 1/2 chance that the gene will be for baldness and 1/2 that it will not, then men have a 1/2 chance (because 1/2^1 = 1/2) of being bald, while women have a 1/4 chance (because 1/2^2 = 1/4) of being bald.  

This is the reason it's called "male-pattern baldness": it is more common in males. However, this does not explain nor rule out the dearth of women with baldness-women can get it too: it's just less common

Animal and Plant Cell Organelles Use the drop-down menus to determine where these organelles can be found. Ribosome Endoplasmic
rjkz [21]

Answer:

  • Animal Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, small Vacuoles, Lysosomes, Mitochondria, Cell membrane, Cytoplasm.

  • Plant Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, Cell wall, Big Vacuole, Lysosomes, Mitochondria, Cell membrane, Cytoplasm, Chloroplasts.

Explanation:

                       <u>   Animal Cells                              Vegetable Cells</u>

Cell wall                          NO                                             YES

Vacuoles       YES, Small and more than ones     YES, Only one and big

Chloroplast                      NO                                        YES

Plasmatic membrane       YES                                            YES

Mitochondria                       YES                                         YES

Lysosomes                       YES                                           YES

Endoplasmic reticulum      YES                                           YES

Golgi apparatus                   YES                                           YES

Cytoplasm                            YES                                           YES

Ribosome                             YES                                           YES

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

However, they have some differences:

<u>Cell wall</u>: A rigid structure that provides support and protection.

  • Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible, so they can adopt different shapes.
  • Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

<u>Chloroplast:</u> these are organelles that accumulate chlorophyll.

  • Animal cells do not have chloroplasts because they do not photosynthesize.
  • Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

<u>Vacuoles</u>:

  • Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.
  • Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

Other differences are:

The animal cell has centrioles, while the vegetable cell does not.

Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.
