I think you mean the coronavirus pandemic of 2019. Hopefully that clarifies!
In behavioural terms, drugs like aspirin are considered negative reinforcers because they stop a person from feeling pain.
Negative reinforcement is a method that can be used to help teach specific behaviours. With negative reinforcement, something uncomfortable or otherwise unpleasant is taken away in response to a stimulus. Over time, the target behaviour should increase with the expectation that the unpleasant thing will be taken away.
For negative reinforcement to work, whatever is taken away must be taken away immediately after the behaviour in question. The end result is to get whatever behaviour is happening to continue and even increase.
Example :
A person hears a loud alarm. They push the STOP button on the alarm to make the noise stop. Now whenever the alarm goes off, they push the STOP button as quickly as they can.
- Before behaviour: Loud alarm
- Behaviour: Person turns alarm off
- After behaviour: No more annoying sound
- Future behaviour: Person pushes STOP every morning to quiet alarm

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

Answer:
c. inner cell mass
Explanation:
The inner cell mass of the blastocyst forms the embryo while the outer layer, the trophoblast forms the placenta.
answer- the last one you said
i think... i'm not 100% sure though
i'm taking the test rn... good luck
