Answer:
Nutrient-rich blood flows into the liver from the intestines through the hepatic portal vein.
Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.
Explanation:
Formulae :

Given: Length of track start to finish= 400 meters
After completing its 4 laps, total distance covered = 400 × 4 = 1600 meters
Time taken by Lila = 6 minutes
= 6 × 60 seconds [There are 60 seconds in 1 minute.]
= 360 seconds
Then, 

But from start to finish displacement = 0 m [displacement is the shortest distance between starting point to the finishing point]
So, 
Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.
Gametes
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes. Gametes are more commonly called sperm in males and eggs in females.
The expected progeny plants of the F2 generation (pink flower x<span> pink flower) will be:
</span>1/4 = 25% RR (homozygous dominant)- phenotype: red
2/4 = 50% Rr (heterozygous) phenotype: pink
1/4 = 25% rr (homozygous recessive)phenotype: white
R- red
r- white
