Answer:
Both (b) and (c)
Explanation:
Fats, steroids and waxes are some of the most common types of lipids. Lipids are non-polar hydrocarbons because of the presence of non-polar carbon-carbon and carbon-hydrogen bonds in there structure.
Generally, polar molecules are soluble in water while non-polar molecules are insoluble in water, hence, lipids do not dissolve in water. There non-polarity also makes them a suitable component in the selectively permeable biological cell membrane.
<span>Carbon enters the atmosphere as carbon dioxide from respiration (breathing) and combustion (burning). This then reacts in the atmosphere in the carbon dioxide cycle, increasing global warming as gases get trapped by the ozone layer. Autotrophs use energy from the sun and inhale CO2 to release oxygen through photosynthesis. Heterotrophs respire and are consumers of plant life, through cellular respiration, waste products are created, organism decay, dead organisms and their waste products then transform into fossils and fossil fuels used for energy resources and feed into the ocean uptake. The entire cycle creates a greenhouse effect on the planet and carbon and nitrogen gases become trapped in the atmosphere.

Animal, Plant and Root Respiration + Auto and Factory Emissions
=> CO2 cycle + sunlight => photosynthesis
=> organism decay, dead organisms + waste products
=> fossils and fossil fuels + ocean uptake
If an egg sits for 3 days in the water, then in will float becasue of the density of the egg
Water (H
2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound and is described as the "universal solvent" [17][18] and the "solvent of life".[19] It is the most abundant substance on Earth[20] and the only common substance to exist as a solid, liquid, and gas on Earth's surface.[21] It is also the third most abundant molecule in the universe.[20]
Answer:
c. platelets - phagocytize
Explanation:
Platelets are blood cells also known as thrombocyte, that helps with blood clotting to stop bleeding. In the case of an injury that leads to blood vessel damage, signals are sent to the blood platelets, once the signals are sent, the platelets and other coagulation react to the blood vessel damage and they form they initiate a plug (clot) to fix the blood vessel damage.
The are usually not involved in phagocytosis, the phagocytes including macrophages, monocytes, granulocytes, and dendritic cells are involved in phagocytosis
