Answer:
How does the mitochondria produce energy for the cell answers key?
Explanation:
Mitochondria are the powerhouses of the cell because they "burn" or break the chemical bonds of glucose to release energy to do work in a cell
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.
Answer:
Resistance = 30 Ω
Explanation:
The resistance of an electric circuit = 
voltage = 24V
current (I) = 0.80A
Therefore, R = 
R = 30 ohms
Answer:
Transgenic organism are the genetically modified organisms on their molecular level by altering their gene to improve the particular quality that is related to the particular gene in the organisms. It can be perform in bacteria, plants and animals, the produced organisms called transgenic organisms. The beneficial applications of such organism are given as follows:
Transgenic bacteria: these bacteria are first organisms to be genetically modified and used for several functions such as human proteins, producing material plastics and many more.
Transgenic plants: such genetically modified plants can be used to enhance food quality and quantity, to make pest resistant breed and increase the extreme condition tolerance and many more.
Transgenic animals: they are used to improve the quality of food supply, improve medicines and research purposes and many more applications.
