Answer:
A
Explanation:
Reptiles arose about 310–320 million years ago during the Carboniferous period.
This process of dna copying would be mitosis.
Answer:
1. use of the wrong antibiotic
2. use of insufficient concentration of the right antibiotic
Explanation:
MRSA means Methicillin-resistant staphylococcus aureus
VRSA means Vancomycin-resistant Staphylococcus aureus
These are resistant forms of the bacteria <em>Staphylococcus aureus</em> to the antibiotics mentioned.
Bacterial resistance to antibiotics occurs when bacteria develop mechanisms that protect them against the effects of previously effective antibiotics.
Misguided and inappropriate use of antibiotics results in resistance, and they mainly occur as a result of two activities:
1. Use of wrong antibiotics: antibiotics are chosen using a microbiological technique called 'sensitivity testing', to determine which antibiotic is effective against a bacterium. However, when antibiotics are taken without proper sensitivity testing, the bacteria develop resistance against such antibiotics.
2. Use of inadequate concentration of the right antibiotic: This involves using less than the minimum inhibitory of minimum bactericidal concentration of an antibiotic against a bacteria. In this case, the organism has ample time to evolve in the presence of the antibiotic, hence the occurrence of resistance.
28. Part A.
A nucleic has a sugar group, a phosphate group, and nitrogenous base. A carbohydrate only has the sugar group units.
Part B
Nucleic acids make up the DNA and RNA which contain the genetic material for life.
Carbohydrates are used to provide energy to the cells.
Part C
Because all life require energy and this energy can be obtained from carbohydrates.

Part A
The phenotype will be red flower.
Part B.
Using the Punnett Square, the results are
RR, Rr, Rr, rr
There are 3 red flower plant for every 1 white flower plant
Part C.
He should cross a wild or pure breed red flower and white flower snap dragons.
Because it doesnt give oxygen, cant do any human things, and it doesnt do anything a plant does, it just gives off fumes. example:plants can breed and breathe, it can grow. fire doesnt breathe it cant breed but it can grow.
