Explain why water use is a concern and how freshwater is vital to human life.

Without fresh water you will die in just a few days.  Plain and simple, no sugar coating, it is a simple morbid fact that helps drive the point across, water equals life.  Most of us learn this along the way, so why are you complacent when you see fertilizers, oil and other pollutants pour into rivers and streams each time it rains?  Would you eat a fish with some weed killer marinade, or drink water with a nice motor oil sheen on top?

  Using less water keeps money in your pocket.  By utilizing basic water conservation techniques you are able to save thousands of gallons of water each year.  You do the math, use less water and the water company charges you less money.  That sounds like a good deal all around.

 Protecting our natural eco-systems from further damage is critical, especially for the survival of some endangered species.  The oceans, streams and lakes that are the lifeblood of so many local eco-systems are used as dumping grounds, hurting everything that relies on these water sources.  The great pacific garbage patch is a great example of the worst side of our wasteful practices.

  Conserving water can also save energy.  In order to pump the water from a central facility into your home or office, energy is required to run that equipment.  For example, studies have shown that in California alone, 6.5 percent of all energy consumed goes towards moving water from one place to another.  So saving water means using less energy which reduces your carbon footprint and helps the country become more energy independent 

For our friends in Florida and other areas prone to sinkholes, water conservation can actually reduce the occurrence of sinkholes.  When the natural aquifers run low, it leaves a gap where water once was.  Simple gravity pushes the ground downward since there is now a void and voila, you have a sinkhole.

The right answer is C. sex cells.

Like all cells, a somatic cell can mutate.

* A somatic mutation, if it is "viable" (if it does not kill the cell, organ or organism that carries it), and if it is not controlled by the body (apoptosis, confinement of the mutated cell) can give rise to new identical cell lines, thus carrying the same mutation.

* In so-called evolved animals (which can not clone naturally), this mutation affects only the organ or the organism concerned, but will not be transmitted to the offspring of the individual.

The answer is the hypothalamus. It is a portion of the brain that comprises a quantity of small nuclei with an assortment of functions. One of the most significant purpose of the hypothalamus is to connect the nervous system to the endocrine system through the pituitary gland.

It depends upon what type of cell which underwent the division. If it is a somatic cell and it underwent mitosis, the number of chromosomes remains unchanged at 46 in each cell. On the other hand, if it is a sex cell, the number of chromosomes is halved (23) after meiosis. By the way, mitosis is the term for cell division among somatic cells and meiosis is for the sex cells.

Answer:

The answers of first question is-D) from higher concentration to lower concentration.

The answer is second question is- A) similar genetic information.

Explanation:

Diffusion is the process in which particles move from that region where their concentration is more to a region where the concentration of these particles is less. Diffusion is a passive process which means it does not require any king of energy to transport the particles because it occurs along the concentration gradient.

During asexual reproduction, parent makes identical copies of itself. As in asexual reproduction, no combination of gamete takes place from outside and the daughter cells have the same copy of DNA as of the parent cell therefore asexual reproduction in parent cell results in offspring with similar genetic information.

Monosaccharides and disaccharides are the monomeric units of carbohydrates. The two units of monomers are joined by a glycosidic bond.

Carbohydrates are biomolecules, which are made up of monomeric units, known as monosaccharides. These monomeric units like glucose join together to form maltose.

The bond between the monosaccharides is glycosidic. It is formed by the dehydration synthesis reaction, in which one monosaccharide (glucose) will lose H-atom, and the other (glucose) will lose an OH-group. Thus, it leads to the elimination of water molecules, and new covalent bonds are formed.

Therefore, monosaccharides are joined by glycosidic bonds.
