Answer:
b. to amplify the signal
Explanation:
A multi-enzyme phosphorylation cascade is a series of signaling events where one enzyme phosphorylates to another, then this last enzyme acts to phosphorylate another protein and so successively, thereby triggering a chain reaction that leads to the phosphorylation of hundreds or even thousands of proteins. A multi-enzyme phosphorylation cascade is known to increase the number of activated (phosphorylated) proteins at each step of the signaling cascade. Phosphorylation is a posttranslational modification capable of activating proteins during long periods, thereby a phosphorylation cascade also enables the activation of multiple proteins before these proteins become inactive again.
One of the purposes of a multi-enzyme phosphorylation cascade is signal amplification, as shown in option B.
We can arrive at this answer because:
A multi-enzyme phosphorylation cascade allows the emission of a sequence of signals, which occur simultaneously.These signals are created from a series of enzymes, each of which emits a signal by phosphorylating a protein.This all promotes thousands of phosphorylations to be promoted at the same time, all giving off signals.This simultaneous emission of signals extends the range of these signals and allows the phosphorylated proteins to emit more signals, further expanding their reception.In this case, we can state that the multi-enzyme phosphorylation cascade has the function of amplifying an emitted signal.

Some people see hydroelectric energy, energy harnessed from water
movement, as a clean alternative to fossil fuels. Others believe that utilizing
this renewable energy source is dangerous for the salmon populations that
rely on water sources for migration. Which environmental factor should be
taken into consideration when deciding to use renewable sources of energy
like hydroelectricity?
a. cost savings from switching from fossil fuels to renewable energy
increases in carbon emissions due to the production of new energy
systems
decreases in renewable energy as they are being used for human
sustainability
d. fluctuations of limiting factors in the ecosystem affected by the new
source of energy
C.
The correct answer is D. Fluctuations of limiting factors in the ecosystem affected by the new source of energy.
Explanation
As is mentioned in the statement, the energy from a hydroelectric plant is obtained through the movement of water that makes move some blades which produce energy with it. lLater, this is transformed and transported to the cities. However, to obtain these clean natural renewable resources, it is necessary to take into account what environmental factors may be affected with the implementation of a hydroelectric plant, because the operation of hydroelectric can affect natural processes such as fish migration, patterns of reproduction, feeding, among others that take place in a river, having negative consequences for these species which would cause an imbalance in nature. According to the above, the correct answer is D. Fluctuations of limiting factors in the ecosystem affected by the new energy source.

A well-known cell-survival pathway involves a kinase called _______ that is activated by the _______, leading to a larger chance that the cell will survive a stimulus that would normally lead to its destruction
Answer:
Protein kinase B (PKB); 3,4,5-triphosphorylated phosphoinositide (PIP3)
Explanation:
Protein kinase B (PKB) is a kinase protein involved in receptor tyrosine kinase regulatory pathways. This enzyme attaches ATP-phosphate groups to serine/threonine residues in order to alter the activity of target protein substrates. PKB is involved in many cellular processes including transcription, cell proliferation and apoptosis. PKB is activated by the 3,4,5-triphosphorylated phosphoinositide (PIP3) enzyme and then this kinase propagates the signal to Akt (another serine/threonine kinase) by phosphorylation of its catalytic domain. The Akt/PKB signaling pathway is well-known to promote cell survival in response to extracellular signals/stimuli.

For the proteins you researched, how does the structure help the protein perform its function?
Answer: Protein structure depends on its amino acid sequence and local, low-energy chemical bonds between atoms in both the polypeptide backbone and in amino acid side chains. Protein structure plays a key role in its function; if a protein loses its shape at any structural level, it may no longer be functional.
Hope this helps.... Stay safe and have a Merry Christmas!!!!!!! :D
The relationship between the structure and function of proteins is complex. The way a protein interacts with other molecules in the cell depends on the precise arrangement of amino acids and the resulting three-dimensional form.
For example, the structure of a protein's active site enables it to bind to particular substrates and act as an enzyme by catalyzing chemical reactions. Signals can be transmitted by receptor proteins because of their binding sites, which fit into particular molecules like keys to a lock. Collagen and other structural proteins form the fibrous network that gives strength and support to tissues.
Molecules can travel across membranes more easily thanks to unique channels or binding sites on transport proteins. A protein's stability, folding and ability to carry out its intended function all depend on its overall structure.

During the bacterial transformation lab, what was the primary purpose of including Ampicillin in the agar
Answer:
allows for selection of E. coli mutants that successfully picked up the plasmid
Explanation:
Ampicillin is a penicilin type medicine or antibiotic that can treat the infections caused by bacteria.
In bacterial transformation lab, the ampicillin is added in the agar in order to select the E.coli mutants which picked the plasmid and have gained ampicillin resistance gene. Bu doing so, it causes the production of the enzymes that prevents the activity of the ampicillin as well as the bacteria survive. The ampicillin antibiotics present in the agar kills the bacteria without having the ampicillin resistance gene.

Answer:
Estuaries is a water body where freshwater from rivers and streams combines with salt water that is coming from the ocean.
Explanation:
Estuaries is a type of water body that is partially enclosed present at the coastal side where freshwater from rivers and streams combines with salt water that is coming from the ocean. Shallow estuary waters create unique habitats for organisms living there because the presence of brackish water refers to the mixture of fresh water draining from the land and salty seawater. The salinity in water change as you move from inland areas out towards the ocean because the water of inland has less salt in it while water of ocean has huge amount of salt present in it so when we move from inland to the ocean salt concentration increases in it. estuaries provide protection for inland areas by filtering pollutants, prevent shoreline erosion, flooding and storm.
what are the causes of antibiotics resistance ?
Answer:
Over-prescription of antibiotics.
Patients not finishing the entire antibiotic course.
Overuse of antibiotics in livestock and fish farming.
Poor infection control in health care settings.
Poor hygiene and sanitation.
Explanation:
Answer: Antibiotic resistance has become a global threat, and with Antibiotic Awareness Week, it is important to understand the series of events that have led the world to this predicament. Originally touted as a miracle discovery, we are seeing that there can be too much of a good thing.
Explanation: The use of antibiotics has saved millions of lives, but its pervasive use to treat any infection, whether serious, minor, or even viral has lead to the increase in antibiotic resistance. Antibiotics strictly target bacteria, but it is sometimes difficult to differentiate between viral and bacterial infections without costly tests. It is often less time-consuming and more cost effective to proactively prescribe antibiotics, rather than take precautions and prescribe only the correct treatment.
Another issue with antibiotics is the inability to monitor patient intake. Antibiotic dosages are designed to eradicate entire populations of the pathogens. When antibiotics are not taken for the entire prescribed course, pathogenic bacteria can adapt to the presence of low dose antibiotics, and eventually form a population that is completely resistant to the antibiotic regardless of the dosage.
Antibiotic usage is also not exclusive to humans. Every day, antibiotics are used to treat livestock and fish to prevent infections. Similar to overuse in humans, uncontrolled use of antibiotics creates a reservoir of bacteria that could become resistant, thus rendering the antibiotic useless.
