I’ll go with False? Mainly because I’m thinking that some genes may change in the body overtime. Like a mutation of the DNA that might change the cell(s).
Answer:
The correct answer is: A. The genes for insulin production are not activated in heart cells.
Explanation:
<u>DNA </u><u>is present in practically every cell in an organism</u>, but not every cell performs the same tasks as the rest. This happens because genes in the DNA <u>code for different types of proteins</u>, from enzymes to transporters, that impact greatly on the <u>function</u> of a cell; and these genes can be activated or inactivated which will directly correlate to the type of cell and the function that it has.
<u>If the cells in the pancreas can produce insulin but the cells in the heart can't it's because the cells in the heart have the genes for insulin production inactivated</u>.
The amount of mitochondria and ribosomes does not directly affect the production of insulin.
A common human child, they grow from a infant to a teen and go through changes.. Or maybe a plant they go from a seed then develop into a small plant then grow bigger as long as their life continues.
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.
Answer:
This is an example of adaptation due to a progressive mutation
Explanation:
At the beginning, the bacteria can use the galactose as carbon source for it needs, but since this food is getting out in every new generation. The new generations can be adapted to survive with smaller quantities of galactose until there will be one generation that can survive with any galactose source, when this offspring reach the area of the plate without galactose, then it can be grown in ant area.
