Answer: Water will leave the cell and the cell will shrink.

Explanation:

Osmosis is the net movement of water from an area of low to high concentration of solutes through a semipermeable membrane. If none of the compartments contains solutes, then the water moves in either direction between the compartments. <u>However, if we add a solute to one of the compartments, this will affect the probability of water molecules leaving that compartment and moving into the other compartment.</u> The ability of water to move into or out of a cell is called tonicity. The tonicity of a solution is related to its osmolarity, which is the total concentration of all the solutes in the solution. A solution with low osmolarity has few solute particles per liter of solution, whereas a solution with high osmolarity has many solute particles per liter of solution. When two solutions with different osmolarities are separated by a membrane permeable to water but not permeable to solutes, water diffuses from the side with lower osmolarity to the side with higher osmolarity. So, solutions can be:

  • <u>Hypotonic</u>: The extracellular fluid has a lower osmolarity than the fluid inside the cell, it is hypotonic with respect to the cell, and the net flow of water will be into the cell.
  • <u>Hypertonic</u>: The extracellular fluid has a higher osmolarity than the cytoplasm of the cell, it is hypertonic with respect to the cell and water will flow out of the cell.
  • <u>Isotonic</u>: The extracellular fluid and the cell have the same osmolarity so there is no net movement of water.

If a cell is placed in a hypertonic solution, water will leave the cell and the cell will shrink due to the difference in pressure and may even die from dehydration.

Give an example of two types of cells that never go through cell division once fully formed.
AnnyKZ [126]

Answer:

The two types of cells that never go through cell division once fully formed are nerve cells and muscle cells.

Explanation:

The nerve cells and the muscle cells not undergo cell division after formation, because they can never re grow or cannot be repaired once they are mature. We should take good care of it once they are matured. They just under division from being baby to teenagers after that they stop undergoing cell division. This is true for both elephants as well as human beings. This thing is also applicable in case of bones.

Can someone write me an essay on the effects of pollution on the ocean? 500 words
Kryger [21]

Explanation:

Everything in this world we use comes from the ocean in some way. The air we breathe, the water we drink, even the products we use day to day, would not be possible without the ocean. That's why the issue of ocean pollution is so important and needs to be addressed as soon as possible. We depend on the ocean for so much in our life, without it we would surely become extinct. People seem to think that since the ocean is so large and vast, we can dump as much waste as we'd like into it and it will never have an effect on us. However, since we've been polluting the ocean as far back as Roman times, the evidence of ocean pollution becoming a major problem is all too clear. There are many different ways the ocean can become polluted.Fishnets improperly discarded into the ocean can also cause major issues, tangling into unsuspecting mammals and fish. According to the Marin Academy's Oceanography website, there are over 46,000 pieces of plastic floating in each square mile of ocean off the Northeast coast of the United States, which contributes to the death of 100,000 marine mammals and two millions sea birds yearly. A way you wouldn't expect pollution to be caused is by noise. The pressure from the sounds omitted by ships, sonar devices, oil rigs, and earthquakes can disrupt communication, hunting, migration, and reproduction patterns from many marine animals like whales and dolphins. This can throw the whole system off balance. Air pollution can also cause ocean pollution by being absorbed into the water and contaminating it, and vice versa. Ocean pollution can eventually cause air pollution. Dirt can also spill into waterways from top soil or silt from fields or construction sites, causing endangerment to fish and wildlife habitats. Out of all of these ways, oil spills can cause a noticeably excessive amount of damage to the ocean. Although only 12% of the oil entering the sea is caused by spills, they can deteriorate ocean life and environment more than any other pollution. One gallon of used oil spilled into the ocean, which contains toxic chemicals and heavy metals severely dangerous to the micro-organism at the base of the food chain, can cause an eight-acre layer

out at the beautiful ocean, the silky sand and gorgeous seashells lay underneath my feet. The blue waves crashing down onto the shore. The ocean is truly a beautiful sight to see. However, we are slowly ruining this beautiful thing because of the way we treat this planet, the ocean is extremely polluted and marine life is paying for it. A few of the ways mankind is damaging marine life is by heavy oil pollution, and exposing marine life to dangerous chemicals. One way our oceans are polluted is because.

Ocean Pollution Ocean pollution kills marine life everyday and damages the ocean in many ways that sometimes can't be fixed. The real question is where does it all go? Much of it ends up on our beaches washed in with the waves and tides, some sinks, some is eaten by marine animals mistaking it for food. The majority of pollutants going into the ocean come from activities on land. According to the United Nations Environment Programme (UNEP).

Ocean pollution is one of the most urgent issues in our world today. The ocean is crucial to our ecosystem and it is being severely damaged at an alarmingly increasing rate. In this paper I will educate about the role the ocean plays in our beautiful Earth, why it is being so widely ignored and dismissed, the causes of pollution, and its effects on animals and humans alike. Since the beginning of the human race, people have flocked to the ocean. The largest civilizations were built in fertile, coastal

The oceans face many types of pollution every day, every second. The ocean is our greatest ecosystem and out most valuable resource. A common misconception is that the rainforests are the lungs of the planet however, the majority of our oxygen is made via the algae in the sea. The oceans feeds, hydrates, and provides us with oxygen; ironically enough, despite its monetary value to mankind, it is what is treated the worst. For ages we have been dumping our trash, chemicals, and waste into the oceans

I'm in the ocean every day, it’s my second home. Because of this, I am very sensitive to literary and other pollution that ends up in our oceans. I can't walk down the beach today without seeing a pile of trash. Because of this curiosity, I wanted to research what another type of litter fill our local ocean. Our ocean is filthy, Plastics and fibers make their way into the sea naturally every day. Apart from the rest of the trash, some of these plastics and fibers are microscopic, coining the terms.

"the _____ controls the release of our body s stress hormone, cortisol."
zepelin [54]
The correct answer is HPA axis.

The Hypothalamic-Pituitary-Adrenal (HPA) axis is one of the most important neuroendocrine systems, which regulates the stress response and other functions such as the digestion, mood, emotions and the immune system.

The hypothalamus, when triggered by a possible stressor, releases two hormones; the vasopressin and the corticotropin-releasing hormone (CRH). CRH, in turn, triggers the release of the adrenocorticotropin hormone (ACTH) from the pituitary gland. As a result of the secretion of ACTH, cortisol is secreted by the adrenal cortex.

Cortisol is a steroid hormone, considered to be our body's stress hormone.
