Answer: The given statement is false.
Explanation: An electric motor converts electrical energy to mechanical energy and not potential energy.
Mechanical energy is the sum of kinetic and potential energy possessed by an object. It is the energy associated due to the movement and position of an object.
An electric motor works by the process of electromagnetic induction which happens when a voltage is induced by a changing magnetic field.
Answer: C. atp and carbon dioxide gas
The increased pressure forces the carbon chain structure of whatever element into a crystalline structure since that's the most resilient molecular structure. so is A
Answer:
Ss (male) × Ss (female)
Explanation:
This question involves a single gene coding for hair length in guinea pigs. Based on the information in this question, the allele for short hair (S) is dominant over the allele for long hair (s). This means that a guinea pig will only be phenotypically long-haired if the genotype is "ss".
According to this question, Two short-haired guinea pigs are mated several times. Out of the 100 offsprings produced by this cross, 25 of them have long hair (recessive). This means that the phenotypic ratio of this cross is 3 short hair : 1 long hair i.e. 100 - 25 = 75 short hair. 75/25 = 3/1 = 3:1
To produce this phenotypic ratio, the parents must both be heterozygous (Ss) for the hair length gene.
