Portal circulation is a unique form of circulation that occurs at a few locations across the body when veins instead of arteries provide blood to the capillary bed.

Micro circulation is the movement of blood over a capillary bed from an arteriole to a venule. To allow for the exchange of nutrients and other biological components between the blood through circulation and the surrounding tissue, blood flow in the capillaries slows down. Only a single red blood cell may get through without deforming.

A man is 1.7 m long. A paramecium is 85 µm long. How does the length of the man compare to the length of the paramecium?
NISA [10]

Answer is C. The man is twenty thousand (2 x 10⁴) times larger than the paramecium.

1 meter (m) = 10⁶ micrometers (µm)

Therefore, 1.7 m = 1.7 × 10⁶ µm

Thus, the length of the man compared to the length of the paramecium will be

1.7 × 10⁶ / 85 = 2× 10⁴ .  

Therefore, length of the man is  2× 10⁴ times larger than the length of the paramecium.

The Punnett square predicts the ratio of genotypes in the offspring based on the genotypes of the parents. Which Punnett square
Fudgin [204]

Answer:

A Punnett square is shown. The columns are labeled Upper D and d. The rows are labeled d and d. Clockwise from upper left the boxes contain: Upper D d, d d, d d, Upper D d.

Explanation:

Punnett square is used to depict the cross between two organisms. Progeny genotypes can be determined by punnett square. Columns and rows are labelled according to the alleles present in the genotype of respective parents, in this case the mom and the dad.

It has been given that the mom is heterozygous for dimples trait. Since, heterozygous genotype has two different alleles together, mom's genotype must be Dd. Dad is homozygous for no dimples so he can either be DD or dd depending on the dominance nature of the trait. Out of the given options, only the selected option has one heterozygous genotype (Dd) and one homozygous genotype (dd) together hence it is the correct option.

As bile is produced and secreted, what structures or cells does it encounter?
eimsori [14]

The order is Hepatocyte, Bile canaliculus, Common hepatic duct, Cystic duct, and Gallbladder.

<h3>What is bile?</h3>

The liver of most vertebrates produces bile, also known as gall, which is a dark-green to the yellowish-brown fluid that aids in the small intestine's breakdown of lipids. Bile is continuously created by the liver in humans (liver bile), and it is stored and concentrated in the gallbladder. Hepatic bile is made up of 200 meq/l inorganic salts, 0.7% bile salts, 0.2% bilirubin, 0.5% lipids (cholesterol, fatty acids, and lecithin), and 97-98% water. Biliverdin, a green oxidized version of bilirubin, is one of the two primary pigments in bile. They combine to give feces their specific brown hue color. Adult humans produce about 400 to 800 milliliters of bile every day.
