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:
Gametic cells.
4 cells.
Chromosomes number reduces to half.
Explanation:
Meiosis may be defined as a type of cell division in which a single parent cell divides to form the daughter cells. The sex cells or gametes (sperm and ova ) undergoes the meiosis division.
The single parent call divides into four daughter cells by the process of meiosis- I and meiosis- II. Meiosis II is similar to the process of mitosis.
Meiosis is also known as reduction division. The chromosome number reduces to half as compared with the parent cell. The haploid cells are produced in the meiosis.
Integrase is the viral enzyme that catalyzes the Integration of virally derived DNA into the host cell DNA in the nucleus, forming a provirus that can be activated to produce viral proteins.
Answer: Option C
Explanation:
The nephron is the microscopic structure found in the kidney. It is the structural and functional unit of kidney.
It is composed of renal tubule, glomerulus and Bowman's capsule. The renal corpuscles consists of a tuft of capillaries which is known as glomerulus.
Bowman's Capsule can be defined as a sac like structure that lies at the starting of the tubular part of a nephron in a kidney. It performs the first step of filtration of blood that reaches the kidney.
Hence, the correct answer is all of these.
