False

In case of all polar molecule the amount of inter molecular forces (such as cohesion, adhesion etc.) is much smaller than intramolecular forces (such as dipole –dipole interactions, Hydrogen bonding etc.)

Due to this reason a polar molecule form a dipole –dipole structure due to which the charges are unevenly distributed on different parts of  neutral molecule. The electrons are more strongly oriented towards oxygen atom and thus it gets negatively charged and hydrogen gets positively charged. A polar molecule attract another polar molecule either through Hydrogen bonding or through dipolar attraction between them.  

For example dissolution of HCl in water is a polar -polar molecule interaction.

Write a paragraph on how Blood Glucose goes with Negative Feedback
vagabundo [1.1K]

Answer:

Here are some explanations from 0nline so if you want rewrite in your own words

hope this helps  :))

blood glucose-

"The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels."

"If the blood glucose level is too low, the pancreas releases the hormone glucagon. This travels to the liver in the blood and causes the break-down of glycogen into glucose. The glucose enters the blood stream and glucose levels increase back to normal. This is an example of negative feedback."

body temperature-

" Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body."

"Body temperature is controlled by the hypothalamus in the brain. If the hypothalamus detects that the body is too hot, the response is that the body begins to sweat to try and reduce the temperature back to the correct level."

"Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances."

"Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback"

Given that a virus divides every 3 hours, and that a cell lyses (explodes) after it reaches a viral load of 5,000,000 units, how
vladimir2022 [97]

The replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

<h3>How to calculate the Exponential growth/decay formula?</h3>

x ( t ) = x 0 × (1 + r ) t

  • x(t) is the value at time t.

  • x 0 is the initial value at time t = 0.

  • r is the growth rate when r/ 0 or decay rate when r < 0, in percentage.

  • t is the time in discrete intervals and selected time units.

Whit this information, we can conclude that the replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.
