Answer:
The nephrons of the kidneys process blood and create urine through a process of filtration, reabsorption, and secretion. Urine is about 95% water and 5% waste products. Nitrogenous wastes excreted in urine include urea, creatinine, ammonia, and uric acid.
Most lipids are <u>nonpolar</u>. This property causes lipids to be <u>water-insoluble</u> in the bloodstream. Lipoproteins form <u>water-soluble </u>complexes for transport through the bloodstream by surrounding <u>nonpolar</u> lipids with <u>polar </u>phospholipids and proteins .
A central hydrophobic core of non-polar lipids, predominantly cholesterol esters and triglycerides, makes up the complex particles known as lipoproteins. Since lipids like cholesterol and triglycerides are not soluble in water, they must be carried in the bloodstream along with proteins called lipoproteins.
These lipoproteins are essential for the small intestine to absorb and transport dietary lipids, for lipids to travel from the liver to peripheral tissues, and for lipids to travel from peripheral tissues to the liver and intestine.

This is a law because the math behind it is simple and makes
sense – is scientifically proven and developed and is designed to be used. If
double the force, you have double acceleration, double the mass, you get half
the acceleration. A theory is an opinion or an idea, this is a law because it
is sound and the only law for this theme, it stands true for every scenario.
<span>a...it is a fixed equation that is true for
every scenario...</span>
Answer:Prevailing winds are from the southwest in summer and from the northwest in winter while storms and northeast wind (nor'easters), which have the most potential to cause coastal erosion, occur mostly in the fall.
Explanation:
The correct statement is that "Archaea are older organisms than eukaryotes"
- Archaeans are group of organisms classified under the domain Archaebacteria. They are found in environments with extreme conditions e.g. high temperature etc.
- They are prokaryotic in nature i.e. they do not possess a membrane-bound nucleus in their cells.
- Based on this, archaea are not classified under the same domain as bacteria (domain- protista). They are unicellular organisms.
- However, archaea are older set of organisms than eukaryotes. This is the correct statement among the options provided.
