Answer:

a. Undefined  

b. Bacteria

c. Viruses

d. Parasite

e. Bacteria

f. Parasite

Explanation:

In the first case is imperative to obtain more information in order to determine the causes of this contagious disease (contaminated seafood may be associated with different types of infections).

<em>Vibrio vulnificus</em> is a Gram-negative pathogenic bacterium associated with the consumption of contaminated oysters. <em>V. vulnificus</em> causes gastroenteritis, necrotizing infections and invasive sepsis.  

Jaundice is a condition caused by hepatitis A, B and E viruses, it is a disease associated with poor liver function and the destruction of red blood cells.  

<em>Cryptosporidium parvum</em> is a protist parasite (Phylum Apicomplexa) that causes the diarrheal disease cryptosporidiosis. <em>C. parvum</em> parasite is present in contaminated foods and water.

<em>Salmonella enterica </em>is a Gram-negative bacterium transmitted by eating contaminated foods, which causes severe diarrhea, fever and abdominal pain. Salmonella infection may also cause inflammatory diseases and dehydration.

<em>Thichinella spiralis </em>is a parasitic nematode that causes the trichinosis, a disease where larvae migrate to muscle, thereby producing muscle pains and serious pathologies. Trichinosis is caused by eating undercooked meat from contaminated animals.

During an interphase lasting 23 hours the S stage takes average 8.0 hours.What is the percentage of interphase is taken up by S
Alik [6]

The right answer is 34.78%

The interphase is the period of the cell cycle that the cell transcribes its genes and the chromosomes are duplicated. It can be subdivided into several phases:

* phase G1

* phase S: during which the chromosomal material is doubled by DNA replication. This is called chromosome duplication.

* phase G2.

Phase G1 is the longest phase of the interphase (its duration depends on the type of cell), followed by phase S, then phase G2.

To calculate the proportion of phase S in the interphase simply make the division:

phase duration S / interphase duration = 8/23 = 0.3478 (in percentage that is 34.78% (0.3478*100)).

How do jellyfish fit into the cladogram of invertebrates?
Ipatiy [6.2K]

Cladogram is a diagram that tells the relationships between different groups of taxa called “clades”.  Cladogram gives phylogeny (evolutionary history) of the taxa. The organisms which share derived characteristics are grouped together while constructing a cladogram. Jelly fish is a cnidarian share common characteristics such as radial symmetry, simple tissues and no body organs with other members like corals and sea anemones.
