Answer:
Nucleotide ( monomer )
Explained Definition:
The classes of biological molecules may be grouped into the types of polymers they form and the monomers that act as subunits: Lipids - polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids
1. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.
2. Polysaccharides, also called glycans, are large polymers composed of hundreds of monosaccharide monomers. Unlike mono- and disaccharides, polysaccharides are not sweet and, in general, they are not soluble in water. Like disaccharides, the monomeric units of polysaccharides are linked together by glyosidic bonds.
3. Fatty acids form more complex lipid polymers called triglycerides, triacyclglycerols or triacyl glycerides when each single-bonded oxygen molecule bonds to a carbon that's part of a glycerol molecule. ... Triglycerides are also commonly found in foods, especially animal products
4. polymers are known as polypeptides; monomers are amino acids. Nucleic Acids - polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group

The volume (V) of a cylinder can be determined by using the formula
V = ar?h,
where r = the radius of the base, and h = the height of the cylinder. What is the result
of solving this equation for r?
Answer:
Explanation:
To solve for r, simply means to isolate the variable:
[tex]V = pi*r^2*h\\[/tex]
The inverse of multiplication is division, so divide both sides by pi and h
[tex]\frac{V}{pi*h} = r^2[/tex]
[tex]r = \sqrt\frac{V}{pi*h}[/tex]
what three patterns of biodiversity did darwin observe
Answer:
Species vary globally, species vary locally, and species vary over time.
Explanation:
Darwin noticed three distinctive patterns of biological diversity.
Charles Darwin observed three patterns of biodiversity during his exploration on the voyage of the HMS Beagle and in his subsequent research:
Species Variation: Darwin noticed that within a particular species, there is a wide range of variation among individuals.
Geographical Distribution: Darwin observed that different regions of the world have distinct sets of plant and animal species.
Fossil Record: Darwin studied the fossil record and recognized that it contains evidence of extinct species that differ from those currently living.
Thus, these three patterns of biodiversity species variation, geographical distribution, and the fossil record were instrumental in shaping Darwin's theory of evolution by natural selection.

Why do lysosomes keep their digestive
enzymes in membranous sacs?
A. because the membranous sacs can sense when the cell is about
to be attacked
B. because the membranous sacs keep the digestive enzymes
from destroying the cell
C. because the membranous sacs act as tails that help the
lysosomes move faster
D. because the membranous sacs act as factories helping the
digestive enzymes make proteins
The correct answer is option B. because the membranous sacs keep the digestive enzymes from destroying the cell.
What is the purpose of the membrane surrounding the lysosome?The membrane surrounding the lysosome is vital to ensure these enzymes do not leak out into the cytoplasm and damage the cell from within. In order to maintain the acidic pH of the lysosome, protons are actively transported into the organelle across the lysosomal membrane.
What part of the cell is a membranous sac?
A vesicle is a small, membrane-bound sac that transports substances in cells. The ER moves proteins and other substances within eukaryotic cells. Vesicles that contain newly made proteins move through the cytoplasm from the ER to an organelle called the Golgi apparatus.

distinguish between molecules and compounds. can a compound be made of molecules?
Answer:
Molecules are two or more atoms chemically joined together
Compounds are two or more different elements joined together chemically(heteronuclear or homonuclear).
Explanation:
All compounds are molecules, but not all molecules are compounds. a molecule can be made of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule, all compounds are made up of two or more different types of atoms.One that is used a lot is water(H2o)
