What do you mean by fermentation?

The metabolic process of fermentation alters the chemical composition of organic substrates through the action of enzymes. The process of generating energy from carbohydrates without the presence of oxygen is expressly stated as such in biochemistry. If the action of microbes produces the intended alteration to a food or beverage, it may more broadly refer to any process utilized in food production. Zymology, or fermentation science, is a field of study. The primary mechanism by which bacteria manufacture adenosine triphosphate is fermentation, which involves the anaerobic degradation of organic molecules (ATP).

The only phylum in the group Parazoans is ________. A. Porifera B. Cnidaria C. Lophotrochozoa D. Ctenophora E. Ecdysozoa
ludmilkaskok [199]

Answer:

A. Porifera

Explanation:

Parazoan is a sub-kingdom of animal consisting only of the phylum of sponges (porifera), having two tissue layers only and lacking a nervous system and true digestive cavity.

They have certain characteristics like: sponges are marine, but there are some freshwater sponges that enjoy their water without salt. Most sponges do not have any type of symmetry, but some are radially symmetrical and they come in a variety of shapes, colors, and sizes, they are multicellular, heterotrophic and lack cell walls. Unlike other organisms, sponges lack true tissues and organs.

The mesohyl functions as an endoskeleton in most sponges, and is the only skeleton in soft sponges. This mesohyl is stiffened by mineral spicules, by spongin fibers or both.

What is the electrical pathway of the heart, in order? NOTE- this includes pacemaker and conduction components.
s2008m [1.1K]

Answer:

The correct answer will be option A.

Explanation:

The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.  

This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.

Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.

Thus, option-A is the correct answer.
