What is the main source of downward convection<span> flow in the mantle called? The downward sliding characteristic of ridge-push is the result of what? </span>What causes<span> the </span>thermal convection that drives plate motion<span>? Is it the downward arm of convective flow in the mantle?
Here's your answer...
</span>The heat driving<span> mantle </span>convection<span> has three sources. "Primordial" </span>heat<span> (left over from the accretion and differentiation that led to the formation of Earth's core) contributes 20 to 50% of the </span>heat<span>. ... Mantle </span>convection<span> is the main mechanism by which this </span>heat<span> escapes from the interior of Earth.

The electrons in these bonds carry energy. Within the power plants of the cell (mitochondria), energy is used to add one molecule of inorganic phosphate (P) to a molecule of adenosine diphosphate (ADP). The amount of energy stored is about 7,300 calories for every mole of ATP formed.
The needs with the amount of budget from highest to lowest include
- Food
- Education
- Household operation
- Savings
- Medical & dental
- Utilities
- Recreation.
The most important aspect of life in organisms is food as we need it to stay
alive and healthy which is why it has the highest budget.
Education comes second due to it ensuring people are learned ,developed
and has a relatively high cost.

Answer:
D.all lipids contain fatty acids.
Explanation:
A.Lipids are fats, like oil, that are insoluble in water. ... The most abundant class of lipid molecule found in cell membranes is the phospholipid. The phospholipid molecule's polar head group contains a phosphate group. It also sports two nonpolar fatty acid chain groups as its tail.
B.The simplest definition is a lipid as any molecule that is insoluble in water and soluble in organic solvents. Most lipids are soluble to some extent in organic solvents such as hexane, ether, chloroform or benzene. They constitute a complex collection organic compounds that include fatty acids, (A,D, E and K).
C.There are two major types of lipids- simple lipids and complex lipids. Simple lipids are esters of fatty acids with various alcohols. For eg., fats and waxes.
D.Not all lipids have fatty acids. The operational definition of a lipid is a biomolecule is that is sufficiently hydrophobic to be more soluble in an organic solvent than in water. The common theme to their structures is a high percentage of hydrocarbon character.
E.Most lipid hormones are steroid hormones, which are usually ketones or alcohols and are insoluble in water. Steroid hormones (ending in '-ol' or '-one') include estradiol, testosterone, aldosterone, and cortisol. ... Amino acid-derived hormones and protein hormones are water-soluble and insoluble in lipids.
Antibiotic resistance happens when an antibiotic lost its ability in controlling or killing bacterial growth. At this moment the bacteria are already resistant to the antibiotic and are multiplying even though the drug is present. This is a natural phenomenon.
