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.

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.
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.
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

Virus
Answer:
Viruses are not alive
Explanation:
Viruses are acellular structures capable of performing some biological functions.
What are viruses?Viruses are parasitic structures made of an outer protein capsid and genetic material which are able to replicate in a living cell and thus cause infection in the cell.
Viruses hijack the replicative machinery of the host to produce copies of its own genetic material. A single infected cell is capable of producing thousands of viruses.
The virus only injects the nucleic acid inside the target cell, the envelope and capsid are left outside. The hijacked genetic machinery of the host produces further copies of the nucleic acid, capsid and envelope.
These structures are assembled to give rise to new viruses.
If a large number of viruses are synthesized rapidly, it results in cell lysis. This type of infection is called the lytic cycle.
If the virus genome incorporates with the host genome, it is present there silently and being replicated. Upon receiving an activation signal lytic cycle is activated. It is called the lysogenic cycle
Therefore, viruses are acellular structures capable of performing some biological functions.
