Answer:

The question lacks options, the options are:

a. They must be continuously replaced after each catalyzed reaction

b. They increase the energy that is released by reactions

c. They are not used up by reactions

d. They increase the energy that must be absorbed by reactions

The answer is C

Explanation:

Enzymes are proteinous biomolecules produced by living organisms. They act as biological catalysts and regulate the rate of biochemical reactions in living cells by binding to the reactants/substrates involved in the reaction. Most reactions will not occur or occur slowly without certain enzymes.

Enzymes, like other catalysts share the same catalytic properties including the fact that they do not get used up or changed in any reaction they regulate, instead they are released and used again.

Answer:

The type of layout that would be used to construct such rooms is:

fixed-position layout.

Explanation:

With this type of layout, the life support systems for each room will not be moved from one room to the next.  Each room will have its own specialized equipment and systems so that only the workers and some test materials will be moving into and out of the separate rooms.  There are other types of layout, including hybrid, process, and product layouts.  Fixed-position layouts are more appropriate for systems and equipment that are too large or too heavy to move or require separate use to reduce contamination.

What are the four types of tissues?
ElenaW [278]

The term ''tissue'' refers to a group of similar cells. Being a combination of equal cells, a tissue has the same function in any part of the body.

The four types of tissues are:

. The epithelial tissue

. The connective tissue

. Muscle tissue

. The nervous tissue

. The epithelial tissue serves as a cover, among these are the skin and the lining of several ducts inside the body. It is divided into two general classifications: Simple Epithelium and Stratified Epithelium.

. The connective tissue supports and joins other tissues such as bone, blood and lymphatic as well as adipose tissue and reticular tissue.

. Muscle tissue consists of striated or voluntary muscles that move the skeleton and smooth muscle, such as the one that surrounds the stomach. It is divided into three types: Skeletal Muscle Tissue, Cardiac Muscle Tissue and Smooth Muscle Tissue.

. Nervous tissue is formed by nerve cells or neurons and serves to carry messages to and from various parts of the body. This tissue is present mostly in the brains and spinal cord. It has two types of tissue: The Nerve Cell and the Neuroglia.
