<h3><u>Answer;</u></h3>
The above statement is <u>false </u>
<h3><u>Explanation</u>;</h3>
- The chordae tendineae are a group of tough, tendinous strands in the heart.
- <em><u>The chordae tendineae play a vital role in holding the atrioventricular valves in place while the heart is pumping blood</u></em>.
- The chordae tendineae connect the papillary muscles to the tricuspid valve and the mitral valve in the heart.
- Papillary muscles are located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves via the chordae tendineae and contract to prevent inversion or prolapse of these valves.
Answer:
There are a number of mechanisms through which a bacterial cell might become resistant to a specific antibody.
- Some bacteria might posses a cell membrane which wouldn't allow the transfer of antibiotics into the cell of the bacteria. Some bacterial cells might not have the target sites on which the antibiotics attack. A bacterial cell that would be non-resistant wouldn't block the entry of the drug or it might not lack the site where the drug has to function.
- Some resistant bacteria might produce enzymes that would inactivate the activity of the antibiotics. This enzyme machinery would lack in a non-resistant strain. The resistant bacteria might have undergone mutations over a period of time to evolve a machinery for antibiotic resistance.
They are not made up of living cells.
viruses can’t reproduce or replicate themselves on their own and need a host cell. They don’t grow and can’t make their own energy....
1. Monera (prokaryotes)
2. Protista (eukaryotes)
3. Fungi (eukaryotes)
4. Plantae (eukaryotes)
5. Animalia (eukaryotes)
Problem is where do the Archaea sit? Some put them in Monera, some say there are actually 6 kingdoms - Monera broken into Archaebacteria (ancient bacteria) and Eubacteria (true bacteria).
What I can say is that Archaea are definitely NOT bacteria.
The muscle of the skeletal structure work together to support proper alignment and posture. The balanced strength and flexibility of the skeletal muscles enable good posture, walking, sitting and standing. These muscles hav ethe ability to contract which helps to cause body movement.
