I can’t read it i need my glasses but i lost them do you know where they are?
Answer:
B
Explanation:
The structure of the mitochondrion is key to the process of aerobic (in the presence of oxygen) cellular respiration, especially the Krebs cycle and electron transport.
Before assessing the two given cases, an assumption needs to be made about the digestion of the two types of food items, corn and beef. Let us assume that both get digested by expending same amount of energy by the human body. Let the amount of energy at producer level be an arbitrary X.
Case 1: Corn to human:
Since corn is at the producer level, it will have X amount of energy. The transfer of energy from corn to human will take place with a loss of 90% energy at the producer level. Hence the humans will receive 10% of X amount of energy.
Case 2: Corn to cow to human:
Since corn has X amount of energy, only 10% will pass to the next level, i.e. cow. So cow has 10% of X. Cow transfers only 10% of the energy that it has. Hence humans receive only 10% of 10% of X amount of energy.
It can be seen that humans receive more energy in case 1 than case 2. Hence we can say that it is more efficient for humans to feed on corn.
False, a grill chromosome is a cell! LOL
Answer: 1,2 and 3.
The following are common to transformation, transduction and conjugation.
1. Unidirectional transfer of genes.
2. Incomplete gene transfer.
3. Homologous recombination.
Explanation:
Transformation is the taking up of free DNA from the environment.
Transduction is the transfer of DNA by bacteria to a viruses.
Conjugation is the transfer of Plasmid or circular DNA through a tube between the cells. Incomplete DNA are transferred unidirectional .
