why osmosis is special case of diffusion?
Answer:
Diffusion can be called as osmosis in some cases because if the substance is liquid and passes through a semi-permiable membrane then its osmosis.
WELCOME!
Answer:
Osmosis is a special kind of diffusion because in both cases there is a movement of particles from a higher concentration region to a lower concentration region. The only difference is that osmosis is applicable to the movement of the solvent only through the semi-permeable membrane where the solvent is water.

Almost 40% of the world population and many ecosystems are suffering from water scarcity. Many actions taken in the past have led to the water shortage being experienced today. Evaluate each of the factors listed below. All of these have led to water scarcity EXCEPT: A) sea-level rise B) population growth agricultural demand D) climate change, including drought
Answer:
Water scarcity already affects every continent. Around 1.2 billion people, or almost one-fifth of the world's population, live in areas of physical scarcity, and 500 million people are approaching this situation. Another 1.6 billion people, or almost one quarter of the world's population, face economic water shortage (where countries lack the necessary infrastructure to take water from rivers and aquifers).
Water scarcity is among the main problems to be faced by many societies and the World in the XXIst century. Water use has been growing at more than twice the rate of population increase in the last century, and, although there is no global water scarcity as such, an increasing number of regions are chronically short of water.
Water scarcity is both a natural and a human-made phenomenon. There is enough freshwater on the planet for seven billion people but it is distributed unevenly and too much of it is wasted, polluted and unsustainably managed.

●
Thick skins are dominant to thin-skins
[5]
Parents:
The expected phenotypic ratio of offspring from a cross between a striped watermelon with thick skin is 1/2 thick skin and 1/2 striped watermelon.
What is dominance?In genetics, dominance refers to the expression of a given allele or gene variant in heterozygous individuals.
In dominance, this dominant allele masks the expression of the recessive allele for a given gene locus.
In conclusion, the expected phenotypic ratio of offspring from a cross between a striped watermelon with thick skin is 1/2 thick skin and 1/2 striped watermelon.

Why is knowing agricultural statistics, background information, and soil characteristics about the territory in which your farm is located important?
Knowing the agricultural statistics of where your farm is located is important because it can help a farmer to identify the efficiencies that will lead to more productivity and profitability, less input costs, and optimized fertilizer use. The background information is important to farmers because it helps a farmer know whether or not the ground is good for growing crops, if something had happened to the land before their use. Soil characteristics are important to farmers because fertile soil is important for crop growth. The soil needs to be able to allow water and air to infiltrate, roots to be able to move more, and for biota to be able to thrive.

How do bacterial species build antibiotic resistance?
Explanation:
So when u take antibiotics you kill lots of the bacteria. however you don't kill all of them. the bacteria that is left over hasn't been killed because they are resistant to the antibiotics taken. if left these bacteria will reproduce and build and species resistant to that type of antibiotics which can be incredibly dangerous. this is why it is necessary to finish your full antibiotics course so even if u feel better just to make sure you kill all the bacteria.

The illustration shows an ocean food chain and the concentrations of the toxin DDT at each trophic level. What conclusions can be made as to how DDT impacts this food chain? Include where the concentration of DDT is likely to be lowest, and where it is likely to be highest
DDT increases as it moves up a food chain.
Explain how?DDT increases or biomagnifies if we look at a food chain. DDT is fat-soluble, which means animals store it in fatty tissues. It also takes a relatively long amount of time to break down.
Thus, if a predator consumes multiple organisms and each organism has a small amount of DDT, the amount of DDT in the predator is going to be the result of all of those small amounts combined.

Explanation:
Why do large-scale convection currents occur in the atmosphere?
Explanation:
Convection drives the circulation of air in the earth's atmosphere. The sun heats the air near the earth's equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.

n this experiment, you need to examine the idea of thermal energy transfer. Using a controlled experiment, what might a good question about the variables that affect thermal energy transfer be? Thermal energy transfer depends on many properties, but limit your question to only two.
The thermal conductivity and temperature difference between the surrounding plays a crucial role in the transfer of thermal energy between the materials.
What are the three modes of thermal energy transfer?The three modes of thermal energy transfer include conduction (direct contact of atoms), convection (migration of warm particles), and radiation (migration of electromagnetic waves).
The first property is thermal conductivity. Examples include a cube of ice when positioned in the hand of a man. It causes the ice to melt via the thermal conduction from men's hands.
The second property is the temperature difference. Examples include when a hot cup of tea mingled with a cold glass of water. It changes the temperature to a new value which is different from the exact temperature of both initial fluids.
Therefore, it is well described above.

Which of the following is NOT a result of global warming?
(societal conflicts)
(sea-level rise)
(loss of biodiversity)
(ozone depletion)
Ozone depletion is NOT a direct result of global warming. While both global warming and ozone depletion are environmental concerns, they are caused by different factors and have distinct impacts.
Global warming is primarily caused by the increased concentration of greenhouse gases in the atmosphere, trapping heat and leading to a rise in global temperatures. It results in a wide range of consequences, including the melting of polar ice caps, rising sea levels, extreme weather events, shifts in ecosystems, and the potential loss of biodiversity as species struggle to adapt to changing conditions.
On the other hand, ozone depletion is mainly caused by the release of certain chemicals known as ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs) and halons. These substances break down ozone molecules in the stratosphere, leading to the thinning of the ozone layer. Ozone depletion primarily affects the stratospheric ozone layer, which shields the Earth from harmful ultraviolet (UV) radiation. The thinning of the ozone layer can have detrimental effects on human health, ecosystems, and agricultural productivity.
Therefore, while global warming and ozone depletion are both significant environmental issues, ozone depletion is not a direct result of global warming.

Planet A has a tilt a of five degrees. What seasonal changes would be expected on this planet?
Extreme temperature changes between seasons
Little to no change in temperatures between seasons
Seasonal changes along the equator only
Seasonal changes at the poles only
Answer:
B. Little to no change in temperatures between seasons.
Assuming planet A is the earth, the earth is very slightly rotated on its axis toward the sun and Jupiter, so there would not be a dramatic change if we tilted the earth 5 degrees.
