Answer:
Let assume one of option is - decreasing adhesive forces in between the water molecules and the glass due to mineral solution.
Explanation:
Adhesive force is the attraction of two different types of atoms or the molecules of unlike substances. Water and glass molecules are not similar as water is not having charged molecules like the glass molecules. Water molecules are attracted to glass molecules that are charged due to adhesive force.
Treating the glass with mineral solution decreases the adhesive force which leads to forming drops instead of the puddle.
Thus, the correct answer is -decreasing adhesive forces in between the water molecules and the glass due to mineral solution.
Answer:
This question is asking for the polymer and monomer of nucleotide and protein respectively.
The answer is:
Protein - monomer is AMINO ACID
Nucleotide - polymer is NUCLEIC ACID
Explanation:
There are four major biological molecules found in nature namely: protein, carbohydrates, fats and oil, nucleic acid. These biological molecules are, however, complex and polymeric in nature and like every other polymer, they must contain monomers that make up their structure.
- PROTEINS are made up of monomers called AMINO ACIDS.
- CARBOHYDRATES are made up of monomers called MONOSACCHARIDES.
- LIPIDS are made up of monomers called FATTY ACIDS.
- NUCLEIC ACIDS are made up of monomers called NUCLEOTIDES.

Substitution point mutations are silent mutations and does not cause any significant change in the protein or the phenotype.
Explanation:
A substitution point mutation is a silent mutation resulting from base substitution (one base is substituted for another base on a codon in a DNA sequence) occurring only between two gene points.
The amino acids coding for a protein are formed by codons or the bases grouped together.
When only a single base is substituted, the resulting protein formed will not change since the substitution causes only very mild undetectable changes which cannot bring about strong mutation to change the nature of a protein.
Proteins formed are responsible for the various characters or phenotypes formed in an organism. Hence, the phenotypes of the beetle like the antennae length or the dark color also do not change due to substitution point mutations.
Answer:
more distant galaxies are moving away faster.
the shift towards red (Doppler effect like with sound on Earth) is the indication.
Explanation:
what did this have to do with biology ?
and by the way, this is also something I debate severely in scientific communities, because yes, the red shift is there. but "more distant" also means "more in the past", so that the data shows us actually that things in the past moved faster away. not necessarily today ...
