Its referred to as cohesion

The water molecule has the ability to form hydrogen bonds, between atoms of oxygen and hydrogen of different molecules (they can also be formed between atoms of hydrogen, phosphorus, and nitrogen, but in the case of water we refer only to hydrogen and oxygen). When this phenomenon occurs between molecules of the same species (one molecule of H2O with another molecule of H2O), it is called cohesion, which is the attraction that molecules have for others of the same type. In the case of water, cohesion occurs thanks to hydrogen bonds, and this union is very strong and difficult to break.

Proteus vulgaris has a doubling time of roughly 28 minutes. If an initial population of 500 cells is allowed to grow for 6 hours

romanna [79]

Answer: The final population of Proteus vulgaris after 6 hours is $3.71\times 10^{6}cells$

Explanation:

We are given:

Proteus vulgaris divides and doubles every 28 minutes

Total time given = 6 hours = 360 min (Conversion factor: 1 hr = 60 min)

Number of times Proteus vulgaris doubles in 6 hours = $\frac{360min}{28min}=12.857times$

Calculating the number of bacteria after 6 hours under ideal conditions:

We are given:

Initial population = 500 cells

Number of times it doubles = 12.857 times

Final Proteus vulgaris population = $500\times 2^{12.857}=3709476.8=3.71\times 10^{6}cells$

Hence, the final population of Proteus vulgaris after 6 hours is $3.71\times 10^{6}cells$

Damm [24]

Answer:

Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.6

What is the role of the ion channel (in easy words)

ArbitrLikvidat [17]

Answer:

Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient.

Explanation:

Ion channels are molecular machines that serve as principal integrating and regulatory devices for controlling cellular excitability. Different types of ion channels have been described: channels that respond to mechanical, electrical (voltage-dependent ion channels), or chemical stimuli (ligand-gated ion channels); ion channels that are controlled by phosphorylation/dephosphorylation mechanisms; and ion channels that are dependent on G proteins. Most ion channels are of the voltage-dependent type and consist mainly of sodium (Na+), potassium (K+), and calcium (Ca2+) channels. Drugs can affect ion channel function directly by binding to the channel protein and altering its function or indirectly through G proteins and other intermediates. Lidocaine is a good example of a drug that directly affects voltage-gated Na+ channels by blocking the channel and thus Na+ entry into the cell.

Thanks! Have a great day!
