Answer:
4 amperes
Explanation:
Using the formula; V = IR
Where;
V = voltage (volts)
I = current (amperes)
R = resistance (ohms)
From the formula; I = V/R
According to the information provided in this question, the resistance of circuit (R) is 3 ohms while the voltage (V) produced by the cell in the circuit is 12 volts.
Therefore, I = 12/3
I = 4 A or amperes.
Nucleic acid hybridization is based on the fact that pairing between complementary bases occurs. Nucleic acid hybridization is a<span> technique in which single-stranded </span>nucleic acids<span> (DNA or RNA) are allowed to interact so that complexes called hybrids are formed by molecules with similar, complementary sequences.</span>
Answer:
B. passed through levels A, B, and C to organisms
Explanation:
DDT is an insecticide that passed through the food chain from one trophic level to the next.
The concentration of DDT increases with the each trophic level in food chain and the amount of toxin increases as passes from A to B, B to C, and C to D where D has the higher concentration of DDT as it is the higher trophic level than A, B, and C.
Hence, the correct answer is "B. passed through levels A, B, and C to organisms".
Heterozygous means two alleles are different. In this case, it means one is dominant (P) and the other one is recessive (p).
So genotype of both parents are Pp.
The problem can be solved quickly with a Punnett square:
P p
P PP Pp
p Pp pp
So genotype/phenotype
25% PP polka-dot tail
50% Pp polka-dot tail
25% pp solid-coloured tail
So for genotypes:
PP 25%
Pp 50%
pp 25%
For phenotypes:
75% polka-dot tail
25% solid-coloured tail
