development of continuous flow systems to access secondary amines through previously incompatible biocatalytic cascades
The use of continuous flow reactors enabled previously inaccessible enzyme combinations in multi-enzyme cascade reactions.
The combination of oxidases with aminating biocatalysts (transaminase/reductive aminase) and was extended to the continuous in situ biocatalytic generation of amino donors for the reductive aminase.
The reaction cascades described here started with the generation of aldehydes from stable and commercially available alcohols. As aldehydes are versatile yet unstable intermediates, it was thought a continuous flow system that generated this group in situ at high concentrations could allow for a range of subsequent enzymatic modifications. Biocatalytic oxidations are fundamental in transitioning to a bio-based economy, in particular the use of oxidases which carry out selective oxidation using molecular oxygen as the sole oxidant.
For the first time it has been shown that previously incompatible enzyme cascades can be run continuously, greatly improving the metrics (up to 58-fold for STY and 4-fold for enzyme productivity) when compared to the equivalent batch reactions. This system is extremely versatile with several enzyme combinations tested that enabled the generation of a range of amine intermediates. The reactors were also extended to demonstrate proof-of-concept, high throughput reaction screening in continuous flow. A continuous synthesis of the biologically relevant molecule 4O-methylnorbelladine was also successfully demonstrated. Using a continuous approach allows many additional benefits to those discussed here to further improve biocatalytic reaction efficiency.

What would happen if sulfur was removed entirely?
Sulfur is essential for humans, animals and plants. When it enters our body, it can be incorporated into tissues such as skin and cartilage. It is also found in some proteins and vitamins. if the sulfur were completely removed, it causes several symptoms, such as depression, neuritis, unpleasant odor in the saliva and a decrease in the brightness of the skin. To avoid this deficit, it is recommended to eat fruits and vegetables. Foods of animal origin such as milk and eggs also have it in their constitution.
What is the role of sulfur in the human body?Another great advantage of sulfur is that it has anti-inflammatory action, in addition to being an antioxidant. This means that it fights free radicals and also increases the body's defense against invading agents, preventing, for example, the flu. In addition, the mineral helps to detoxify the body.
With this information, we can conclude that Sulfur dioxide is a toxic gas that mainly affects the mucous membranes, acting on the respiratory system and eyes, causing irritation.

Which Sentence is true about cells?
(A) All cells do the same job
(B) All cells are the same inside.
(C) All Living things are made of cells.
(D) All living things have the same number of cells.
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory.
The survival of a species depends on its ability to adapt to changes in the environment. A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?
Mutations are always passed on to subsequent generations of the species
Mutations lead to genetic variation
Mutations are the cause of disease in the species
Mutations are not harmful when they occur in somatic cells of a species
Answer:
Your answer is B) Mutations lead to genetic variation.
Think of it like this, when rays were first starting to develop, they probably started with only one kind, stingless. Somewhere down the line, the genes of the rays started to mutate and eventually, there were stingrays and stingless rays. Now at this point there are predators that frequently feast upon the rays, so which of the two rays are more likely to defend themselves, and get away to live long enough to reproduce and pass on their genes? The stingrays! The mutation that may have occurred millions of years ago, has determined which organisms were more fit for a changing environment.
The survival of the species depends on the resources available and environmental conditions. The species or organisms capable to adapt to the surrounding have higher chances of reproduction and survival.
The correct answer is:
Option B: Mutations lead to genetic variation
The organisms adapting to the surrounding will undergo an alteration in their genetic sequence, known as mutations. The mutations are heritable and lead to genetic variation.
The mutation leads to genetic variation as:
It leads to the introduction of new alleles in the gene pool.Sexual reproduction and random mating also contribute to genetic variation. The mutations are heritable, and thus can cause an increase in the frequency of the mutated allele in the gene pool.
Thus, the correct answer is that mutation leads to genetic variation.

Explain the similarities between prokaryotic and eukaryotic cells. Explain the difference between prokaryotic and eukaryotic cells.
Answer:
Prokaryotes do not contain membrane-bound organelles or genetic information within nuclei, while eukaryotes contain membrane-bound organelles and do store their DNA in nuclei. Both types of organisms may be producers and consumers
Explanation:
Cells are the basic microscopic elements of all organisms. There are two cell types: Prokaryotes and Eukaryotes.
Prokaryotic describes single-celled microorganisms that do not have a cell nucleus or other organelles surrounded by membranes. Eukaryotes are either single-celled or form complex multicellular bodies. They contain many membrane bound organelles, and their genetic information is stored within a nucleus.
Both groups may contain structures like cell walls, and carry out heterotrophic or autotrophic nutrition.
classify each electrolyte as an intracellular or extracellular anion (negatively charged ion) or cation (positively charged ion).
Electrolytes are substances that, when dissolved in water, conduct electricity. A variety of biological functions depend on electrolytes. They acquire a natural positive or negative electrical charge.
What is intracellular or extracellular ions?
Electrolytes are classified as both intracellular fluid and the extracellular fluid include electrolytes chemicals. The main cation and anion in extracellular fluid, respectively, are sodium and chloride.
Sodium is one of the most crucial electrolytes in the extracellular fluid because it is an active cation. It is in charge of regulating the cell's membrane potential, as well as maintaining the extracellular fluid volume.
All body tissues require the mineral potassium, which is a necessary component. Because it carries a little electrical charge that activates numerous cell and nerve activities, it is also referred to as an extracellular anion.
Therefore, electrolytes are classified as intracellular or extracellular.

Which of the following scenarios can be classified as a negative feedback loop?
a increase in blood pressure to reduce heart rate
b increase in testosterone to help increase a fight-or-flight response
c increase in oxytocin caused by increased contractions
d increase in platelet production to help increase blood clotting
Answer:
The scenario that can be considered an example of a negative feedback loop is increase in platelet production to help increase blood clotting (option d).
Explanation:
Negative feedback loop is what occurs when a change occurs in the body, producing a response that decreases or stops that change, with the intention of maintaining homeostasis.
When there is a wound that produces bleeding, a series of mechanisms are activated, the coagulation cascade, which promotes the release of factors that allow the formation of clots. The increased release of platelets implies negative feedback because it helps to stop the change that occurs in the body, the loss of blood, through the formation of clots.
One thing that can cause confusion is the fact that this response also involves positive, though limited, feedback that promotes the production of clotting factors and platelets to increase clot formation. What really happens is that the positive feedback promotes the general feedback, which is the negative feedback: clot formation to stop the bleeding, restoring homeostasis.
The other options are not correct because:
a. Increase in blood pressure to reduce heart rate is not possible.
b. In the fight and flight response the hormones involved are cortisol and adrenaline, not testosterone.
c. Increased oxytocin in response to uterine contractions is positive feedback.

Factors in the environment that an organism reacts to, such as light, temperature, sound are known as stimulus.
In the field of biology, a stimulus can be described as any kind of change in an environment that is perceived by the sensory receptors of an organism. In order to survive a change, the body has to produce a response to the stimulus.
When a change in the environment i.e stimulus is detected by the sensory receptors, a signal is carried to the central nervous system (CNS). The central nervous system (CNS) determines this change and sends a message through the effector motor neurons with a necessary response action.
Any change in the environment, such as a change in temperature, light intensity, or sound intensity is perceived by the sensory receptors and is a stimulus.
