Explanation:
The passing of traits from parents to offspring is Inheritance (D).
9:3: 3:1 is the phenotypic ratio showing traits as black and long hair : black and short hair: chestnut and long hair: chestnut and short hair when a chestnut horse heterozygous for pacing and hair length with a hybrid horse.
Explanation:
Dominant trait = black hair colour (BB,Bb), trotting (TT,Tt) , long hair (LL,Ll)
recessive trait = chesnut hair colour (bb), pacing gait (tt), short hair(ll)
cross between chestnut horse heterozygous for pacing and hair length will have alleles as BbLl
alleles for hybrid horse will also be heterozygous Bb, Ll
Punnett square to show the cross:
BL Bl bL bl
BL BBLL BBLl BbLL BbLl
Bl BBLl BBll BbLl Bbll
bL BbLL BbLl bbLL bbLl
bl BbLl Bbll bblL bbll
phenotype ratio
black and long hair : black and short hair: chestnut and long hair: chestnut and short hair
9:3: 3:1 is the phenotype ratio.
Answer: The correct answer is B) Superconductor, conductor, semiconductor, insulator.
Resistivity to the flow of electrons is inversely related to the conductivity of the material. This means that more is the resistivity, lesser is the conductivity.
Superconductors are those materials, which have zero resistivity. Thus, they have maximum conductivity, conductors are those that have little resistivity, semiconductors have more resistivity than conductors, and insulators have maximum resistivity so they do not allow the electric current to pass through them.
Thus, B) is the right answer.
Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals
