Answer:

5.2 × 10 ⁹ cfu

Explanation:

Applying the dilution factors

0.1 ml of the final dilution contains 52 colonies

1 ml would thus have around 520 colonies

10 ml of the final sample would contain 5200 colonies

at a 1 / 100 dilution

1 ml of the sample holds 5200 colonies

100 ml of the sample will yield 520000 colonies

1 ml from the 0.1 ml + 9.9 ml encompasses 520000 colonies

10 ml would then have 5200000

following the second stage of the dilution

0.1 ml of the slurry contained 5200000 colonies

1 ml would yield 52000000 colonies

10 ml would lead to 520000000 colonies

100 ml of the starting sample ( 10 grams + 90 ml ) results in 5200000000 colonies =

5.2 × 10 ⁹ cfu

Describe how an amino acid molecule passes from the lumen of the ileum to the liver​
vlada-n [1829]

Answer: Amino acids enter the body using a Sodium cotransporter, employing a mechanism similar to that of monosaccharides.

Explanation: Amino acids are taken up via a Sodium cotransporter, akin to the absorption of monosaccharides. Once absorbed, they cross the alabaster membrane through facilitated diffusion. Di- and tripeptides utilize distinct H+ dependent cotransporters, and upon entering the cell, they are hydrolyzed into amino acids.

Species A and species B are in the same phylum. Species A and species C, but not species B, are in the same order. From this inf
Tresset [1663]

Answer:

Species A, B, and C share the same phylum.

Explanation:

Organisms are categorized based on a taxonomic structure that involves various ranks such as species, genus, order, and family.

This hierarchy includes:

Domain

Kingdom

Phylum

Class

Order

Family

Genus

Species

Species represents the most specific taxonomic rank, while Domain indicates the broadest. Every organism within a lower rank also belongs to a higher-ranked category. For example, all organisms within the same species will also belong to the same genus, but the converse is not necessarily true.

Based on the information provided, since species A and C fall under the same order, it implies they are also classified within the same class and phylum...

Furthermore, species A and B are classified in the same phylum, thus since species C is within the same phylum as A, it indicates that all three species are in the same phylum.
