Which biological toxin is cytotoxic?
Ricin is a biological toxin that is cytotoxic. It is a protein found in the seeds of the castor oil plant and acts by inhibiting protein synthesis in cells, leading to cell death.
Is lipids present in food?
Lipids are present in vegetable oil, olive oil, and others of biological origin. But they are not present in petroleum, which consists mostly of hydrocarbons.
What forms if biological debris remains in lithified rock?
When biological debris is lithified, it can form fossils or organic-rich sediments such as coal or oil. These remnants provide valuable information about past life forms and environmental conditions. Over time, they may undergo further transformation into minerals within the rock.
What is a biological pump?
A biological pump is the collection of biological ocean processes which regulate the uptake, storage, and release of carbon.
Do oil spills evaporate in salt water?
Not entirely. The oil that spilled in the gulf coast will change in composition with time, due to evaporation and biological processes. It may exist the well head as a light oil and wash up later on beaches as an oil emulsion, or tar balls with a much higher viscosity.
What are the biological compounds of oil?
Crude oil compounds: Carbon, hydrogen, sulfur nitrogen, oxygen, metals, salts.
Is the greenhouse effect biological?
No, it is primarily physical. Biological events 300 to 100 million years ago pulled carbon from the atmosphere and locked it up at the bottom of vast swamps, which formed our modern coal and oil deposits. But the burning of that coal and oil is not considered a biological effect. The excess CO2 in our atmosphere is not of biological origin in that sense. Some excess methane gas, however, IS from direct biological sources.

What is liquid fat called?
Animal meats have high levels of fat (beef, pork, etc.). and to be accurate practically all foods from biological sources contain fat as lipids are intergral component of biological systems
Which biological toxin is cytotoxic?
Ricin is a biological toxin that is cytotoxic. It is a protein found in the seeds of the castor oil plant and acts by inhibiting protein synthesis in cells, leading to cell death.
What is the definition of a natural plastic?
A "natural plastic" is a material created from biological sources other than petroleum (oil).
Why is biodiesel called biodiesel?
Because it is derived from biological sources (crops such as rape) and not mineral sources such as coal or oil.
What is the meaning of biofuels and why it is related to oil price?
Bio fuel is made of current biological products (soy bean oil, etc) rather than historic deposits of "mineral" oil. It's expensive to make, and if oil is cheap then no one will bother.
What has the author Eric Schrier written?
Eric Schrier has written: 'Cleanup efficiency and biological effects of a fuel oil spill in cold weather' -- subject(s): Oil spills
Is lipids present in food?
Lipids are present in vegetable oil, olive oil, and others of biological origin. But they are not present in petroleum, which consists mostly of hydrocarbons.
Can used cooking oil as alternative source of petroleum?
No it can not. But it can be used instead of diesel if your engine is suitable or has been modified to take biological fuel.
How does oil affect soil?
Oil can contaminate soil, affecting its physical, chemical, and biological properties. It can reduce soil permeability, disrupt nutrient cycling, and inhibit plant growth. The presence of oil in soil can also impact the soil microbiota, affecting soil health and fertility.
