A mixture can be separated by all of the following EXCEPT
Filtration
Distillation
Sieving
A magnet
Evaporation
All are methods to separate mixtures
Answer:
All are methods to separate mixtures
Explanation:
A mixture consists of 2 or more substances that are mixed physically but not chemically. Hence, mixtures can be separated by any physical separation means which include but not limited to filtration, distillation, sieving, magnetization, and evaporation.
Filtration is usually used to separate suspended particles in a liquid using a membrane of a filter paper. Distillation is used to separate miscible liquids with varying boiling points by evaporating and condensing them back at their respective boiling points. Sieving is used to separate mixtures with varying particle sizes of individual components.
Magnetization is usually used to separate mixtures with, at least, one component with magnetic property. Evaporation is used to separate dissolved solids from liquids.
Hence, all the methods listed are used to separate mixtures.

A student carried out an experiment to determine how different concentrations of sucrose solution will affect osmosis. The student
set up five bags of dialysis tubing with different concentrations of solutions in each one. The first one had distilled water (OM).
followed by 0.25 M.0.5 M, 0.75 M, and 1.0 M sucrose solutions. These bags were placed in distilled water for thirty minutes. The bags
were then massed removed from the distilled water and massed on a scale. Revise the experiment by selecting all of the choices
below that would strengthen the experimental design
Answer:The bags should be massed before going into the distilled water, the temperature of the solutions in the experiment should be held constant, the bags should be kept in the distilled water soil it ion for the same length of time.

Answer:
It allows the cell to regulate the movement of materials into and out of the cell
Explanation:
This molecule is a saturated fatty acid. The cell membrane is made up of a phosphate head and three fatty acid tails that form a lipid bilayer arrangement.
This lipid bilayer regulates the entry and exit of substances into and out of the cell. Small non-polar molecules, like oxygen and carbon dioxide, are soluble in the lipid bilayer and can easily cross the plasma membrane. Small uncharged polar molecules, like water, can pass through the membrane by osmosis. Larger molecules such as glucose, or charged molecules like ions, require active transport to be passed across the cell membrane.
Answer:
It allows the cell to regulate the movement of materials into and out of the cell

what's the difference between pseaudscience and science
Answer:
hope it helps..
Explanation:
Pseudoscience is differentiated from science because – although it claims to be science – pseudoscience does not adhere to accepted scientific standards, such as the scientific method, falsifiability of claims, and Mertonian norms.

1. Summarize the phosphorus cycle? Does phosphorus go into the atmosphere?
Answer:
Phosphorus forms parts of important life-sustaining molecules that are very common in the biosphere. Phosphorus does enter the atmosphere in very small amounts when the dust is dissolved in rainwater and seaspray but remains mostly on land and in rock and soil minerals.
when is the earth closet to the sun
Answer:
Explanation:
January
It is all about the tilt of the Earth's axis. Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January!

The majority of earth is covered with water. Water takes longer to heat up and cool down which has an impact on the air temperature. The slow change in water temperature is due to waters
Answer:
high specific heat
Explanation:
The specific heat of the water plays an important role as it can absorb a lot of heat without a significant increase in the temperature.
Nitrogenous wastes result from the metabolism of what?
Answer:
Explanation:
The nitrogen compounds through which excess nitrogen is eliminated from organisms are called nitrogenous wastes (/naɪˈtrɒdʒɪnəs/) or nitrogen wastes. They are ammonia, urea, uric acid, and creatinine. All of these substances are produced from protein metabolism.

Owls (primary predators of rock pocket mice) are nocturnal visual predators that are able to distinguish effectively between dark and light colors in low-light conditions,
Which of the following best explains the relationship between coat color and predation rate in the rock pocket mouse population on the lava flow rocks with
respect to the different coat color
phenotypes?
Answer: A dark coat color provides camouflage to mice on the lava flow rocks; therefore, mice with dark coats have a lower predation rate in that habitat.
What is G-zero (G0) and why is it important to the cell?
Answer:
The G0 phase describes a cellular state outside of the replicative cell cycle. Classically, cells were thought to enter G0 primarily due to environmental factors, like nutrient deprivation, that limited the resources necessary for proliferation. Thus it was thought of as a resting phase.

Answer: Homeostasis
Explanation: One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.

3. Approximately when was
the Moon full?
Answer:
When the Sun and the moon directly align.
Explanation:
At Full Moon, the entire face of the Moon is illuminated by the Sun's rays and it can be bright enough to light up otherwise dark nights.
Technically, this primary Moon phase only lasts a moment, the instant when the Sun and the Moon are aligned on opposite sides of Earth (see illustration). So the exact time for Full Moon is during the day on parts of the planet.
However, the Moon can appear to be full a day before or after while more than 98% of the Moon's disc is illuminated.
Therefore, it can be difficult to tell the difference between a Full Moon and the last stage of a Waxing Gibbous Moon or the beginning of a Waning Gibbous Moon.
answer:
the last full moon was on _______ 2020
