Imagine you have been shipwrecked and are floating on a small piece of wood in the middle of the ocean. You are terribly thirsty and take a drink of seawater (3.5% salt). What do you think happens to your stomach cells (1% salt), and why?

Answers

Answer 1

Given the higher salinity of the ocean water in comparison to your stomach cells, you will lose water from your cells and become dehydrated.

Osmosis is a phenomenon that shows that in the presence of a space in which the solute concentration is higher than its current location, water will travel towards that more concentrated space in an attempt to dilute the concentration.

The urge to drink is what we call being thirsty. This urge has a biological origin. It is the body's way of telling you that your cells need more water, which leads us to often consume any water we have available. This is not always in our best interest.

However, due to osmosis, drinking the seawater would only have a negative effect on your stomach cells. As stated in the question, the cells contain less concentration of solute (in this case salt) than the water. This means that instead of entering the cell, water would leave to dilute the new seawater, thus dehydrating you more and worsening your condition.

5 organelle cells not found in human cells

Hurry homework due in couple minutes

Answers

Answer:

Not every cell in the human body contains DNA bundled in a cell nucleus. Specifically, mature red blood cells and cornified cells in the skin, hair, and nails contain no nucleus. Mature hair cells do not contain any nuclear DNA. ... As part of the maturation process, human red blood cells destroy their cell nuclei.

This means they have no mitochondria, Golgi apparatus, or endoplasmic reticulum. They also lack a membrane-bound nucleus, although they do have genetic material located in a nucleoid region. Prokaryotic cells are surrounded by a plasma membrane, and some types of bacteria have cell walls as well.

Nucleolus. Within the nucleus is a small subspace known as the nucleolus. It is not bound by a membrane, so it is not an organelle. This space forms near the part of DNA with instructions for making ribosomes, the molecules responsible for making proteins.

Explanation:

Consider the global 'Greenhouse Effect", where thermal energy from the sun is naturally trapped by 'greenhouse gases' present within the Earth's atmosphere. A majority of heat generated from this process is then absorbed by the world's oceans, where it is sequestered and stored. What are some of the predictable consequences recently observed over the past 40-50 years with the observed rise in Global Mean Temperature, correlate with an increase in greenhouse gas emissions from burning of fossil fuels across that same period?
a. retreat of winter and summer sea ice, decreasing the amount of solar energy directly absorbed into the oceans
b. warming of deep ocean water and increased evaporation at the surface
c. warming of oceanic surface temperatures, driving the formation of more powerful hurricanes & rainstorms
d. thermal expansion of oceanic water, leading to mean global sea level rise
e. melting of Himalayan glaciers and collapse of Antarctic ice shelves into the sea

Answers

Answer: it would be C e is correct however but that’s already happened. So that wouldn’t be much of a prediction. Hope this helped :)

Explanation:

Thermal expansion of oceanic water leads to a main global sea level rise. So the correct option is D.

What is the greenhouse effect?

Because it absorbs heat in the form of infrared light from the Sun, a greenhouse gas circulates that heat throughout the atmosphere before losing it to space. Although it has a considerably smaller impact on global temperatures, greenhouse gases also speed up the pace at which the environment can collect short-wave radiation emitted by the Sun.

More heat from the Sun is being trapped in our atmosphere thanks to the accumulation of CO2 that is emitted after the combustion of fossil fuels. Human-made acts are referred to as anthropogenic actions, and the emission of CO2 is one such anthropogenic activity that adds to the current heightened greenhouse effect.

A greenhouse gas's contribution to the greenhouse effect is determined by how much energy it absorbs, how much it reflects back, and how much of it is present in the atmosphere.

Therefore the correct option is D.

Recently there has been a decline in the abundance of life on coral reefs. Scientists are unsure why, but one of the explanations for it is that global temperatures are increasing, making water temperatures rise. These small changes are killing off some of the smallest animals on the reef, which then affects the entire food chain. Which of the following would NOT help protect the diversity of the coral reef?

What are coral reefs?

Coral reefs are among the world's most diversified ecosystem and an underwater habitat that is characterized by corals that construct reefs. 

Coral polyps, the invertebrates responsible for reef formation, come in a variety of shapes and sizes, including vast reef-building colonies, graceful flowing fans, and even small, solitary species.

Coral polyp colonies are bound together by calcium carbonate to build reefs.

According to UNESCO, if we continue to generate greenhouse gases at current levels, the coral reefs in all 29 reef-containing World Heritage sites would be extinct by the end of this century.

The Paris Agreement's goal of keeping global average temperature far below 2°C above pre-industrial levels is the only way for coral reefs to survive.

Hence the correct option is B.

the path of a nerve signal involved in kicking a ball .When and where do you motor or sensory nerves fire?​

Answers

Answer:

Explanation:

the path of a nerve signal involved in kicking a ball .When and where do you motor or sensory nerves fire?​

The nervous system is made up of two parts. Each part contains billions of neurons. The first part is the central nervous system. It contains the brain and spinal cord, which is a fibrous, ropelike structure that runs through the spinal column down the middle of the back.

The other part is the peripheral nervous system. It consists of thousands of nerves that connect the spinal cord to muscles and sensory receptors. The peripheral nervous system is responsible for reflexes, which help the body avoid serious injury. It's also responsible for the fight or flight response that helps protect you when you feel stress or danger.

Let's examine an individual neuron up close.

Here is a peripheral nerve. Each one of the nerve bundles, or fascicles, contains hundreds of individual nerve.

Here's an individual neuron, with its dendrites, axon, and cell body. The dendrites are tree-like structures. Their job is to receive signals from other neurons and from special sensory cells that tell us about our surroundings.

The cell body is the headquarters of the neuron. It contains the cell's DNA. The axon transmits signals away from the cell body to other neurons. Many neurons are insulated like pieces of electrical wire. The insulation protects them and allows their signals to move faster along the axon. Without it, signals from the brain might never reach muscle groups in the limbs.

Motor neurons are responsible for voluntary control of the muscles all over the body. The operation of the nervous system depends on how well neurons communicate. For an electrical signal to travel between two neurons, it must first be converted to a chemical signal. Then it crosses a space about a millionth of an inch wide. The space is called a synapse. The chemical signal is called a neurotransmitter.

Neurotransmitters allow the billions of neurons in the nervous system to communicate with one another. That's what makes the nervous system the body's master communicator.
