Can an enzyme be recycled? Explain.

Answers

Answer:

Enzymes serve as catalysts to many biological processes, and so they are not used up in reactions and they may be recovered and reused. However, in a laboratory setting, reactions involving enzymes can leave the enzyme unrecoverable. This process makes the enzyme at once less reactive but more stable.

Explain how zooxanthellae have a symbiotic relationship with coral.

Answers

Answer:

Zooxanthellae and coral have a mutualistic, symbiotic relationship. Coral obtains oxygen and organic products from the algae that live within them. These algae also help the coral remove waste. The zooxanthellae obtains needed carbon dioxide and needed nutrients from the coral. The coral also provides the zooxanthellae with a protected habitat. Because both organisms derive a benefit from their relationship, it is considered mutualistic.

A symbiotic interaction benefits both the species. Corals and zooxanthellae shows a symbiotic relationship where zooxanthellae produce oxygen and corals perform photosynthesis.

What is Symbiotic relationship?

Symbiosis is a type of species interaction, it is any type of a close and long-term biological interaction which is between the two different biological organisms. Symbiotic relationships are mutualistic, commensalistic, or parasitic type. The organisms, are termed as symbiont.

The corals and the special cells of zooxanthellae have a mutualistic relationship. The corals provide the zooxanthellae with a protected surrounding environment and the compounds which they need for the process of photosynthesis. In return, the zooxanthellae produce oxygen for respiration and helps the coral species to remove waste materials.

Control of glands and the muscles of internal organs is a function of the __ nervous system
A. parasympathetic
B. somatic
C. peripheral
D. autonomic

Answers

Answer:

autonomic

Explanation:

edg 2020

Control of glands and the muscles of internal organs is a function of the autonomic nervous system.

What is autonomic nervous system?

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS) contain both afferent and efferent fibers that provide sensory input and motor output, respectively, to the central nervous system (CNS).

Activation of the SNS leads to a state of overall elevated activity and attention: the “fight or flight” response. In this process, blood pressure and heart rate increase, glycogenolysis ensues, gastrointestinal peristalsis ceases, etc.

Therefore, Control of glands and the muscles of internal organs is a function of the autonomic nervous system.

Explanation:

Even though the images were not displayed in the question, but we know that carbon is a member of group 14 in the periodic table.

Every member of this group possess four electrons on their outermost or valence shell in addition to the nucleus at the center of the atom.

Hence the structure having four outermost electrons and a nucleus represents carbon atom.

When a sample of food is dehydrated and making it bacteria-free, but in a few days bacteria are found in the food, it shows, bacteria which are there were in the food as endospores.

What are endospores?

Endospores are the alternate stage of bacteria, which is the dormant stage, genus Bacillus, and the genus Clostridium,  are examples of bacteria that make endospores.

These endospores are resistant to physical and chemical treatments, so this makes it easier for bacteria to survive in stressful conditions. It is a major threat to the food industry which provide heat treatment to the bacteria but they show resistance due to spore formation.

Therefore,  when a sample of food is dehydrated to kill all of the bacteria in the food, but microscopic investigations indicate that bacteria are in the food, it is due to endospores.

What is Polymer?

A polymer is defined as a substance or material consisting of very large molecules known as macromolecules, which are made up of many repeating subunits. Due to their wide spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.

During the process of polymerization, polymers are formed in which smaller units known as monomers are joined together with the help of covalent bonds. Polymers are of four types:

1. Natural

2. Synthetic

3. Addition

4. Condensation
