Answer:
Taking into account that:
The flow velocity u of a fluid is a vector field
u = u (x, t)
What gives the velocity of a Fluid Plot at position x y time t.
q = || u ||
Now if the flow is continuous as it happens in the blood vessels then:
The flow of a fluid is said to be constant if it does not move over time, that is why the variant would be 0.
Explanation:
As for the pump with narrow vessels, there the area would be less, therefore the flow also and the flow velocity as well. Adding that the friction with the walls increases as it is narrower, thus generating an increase in pressure with the flow of the liquid.
So this is where we have to put emphasis on the biophysics branch that explains the following:
The Venturi effect is explained by the Bernoulli Principle and the principle of continuity of mass. If the flow rate of a fluid is constant but the section decreases, the speed necessarily increases after crossing this section. By the theorem of conservation of mechanical energy, if the kinetic energy increases, the energy determined by the value of pressure necessarily decreases.
Indeed, according to Bernoulli's principle:
P 1 + 21 ρv 12 + ρgh 1 = P 2 + 21 ρv 22 + ρgh 2

Most health experts recommend eating tuna a few times a week and eating shark few times a month because: eating these fish could result in the buildup of pollutants in fat tissue of humans.
<h3>Why health experts recommend tuna and shark to be consumed less?</h3>
Large fish like sharks and tuna feed on smaller fish and can accumulate high levels of environmental pollutants like mercury and the risk also increases as off-shore pollution increases.
Shark meat is recommended only a few times a month because sharks are apex predators who accumulate high levels of toxic chemicals and heavy metals from both skin absorption and from consuming prey. This is called bioaccumulation.

Hmmmmm Ig it’s d but I’m not sure tho
Explanation:
After a physical examination of the child, some of the manifestations that lead the pediatrician or doctor to conclude that the child has had moderate dehydration are the following:
Sunken eyes and in case he is crying, the cry is without tears, dry oral mucosa, and recapillary time greater than 2 seconds.
