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.

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.

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.
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.

Which sampling site had the highest proportion of heavily infected monarchs?
A. Mexico
B. Guif Coast
C. Northern United States
D. South America
Answer:
The correct answer is option D "Mexico"
Explanation:
In February 2008, we gathered grown-up rulers at two discrete overwintering destinations in the Neovolcanic Piles of Focal Mexico:
(I) Sierra Chincua
(ii) Cerro Pelon.
The two locations are situated in Michoacan, Mexico. Butterflies were gathered utilizing standard flying nets with expandable posts.
The commonness of monarchs vigorously infected with OE at every one of these two areas in 2008 was 14.4 and 13.6%.
From ten imitate bunches (five groups for every site), we arbitrarily chose sound and tainted butterflies following starter screening of parasite tests in the field, for a sum of 75 solid and 100 intensely infected monarchs.
How does petrification link to how the oldest fossils are found in the lowest rock
Answer:
Explanation:
In geology, petrifaction or petrification is the original material and the filling of the original pore spaces with minerals. Petrified wood typifies this process, but all organisms, from bacteria to vertebrates, can become petrified. Petrification (petros means stone) occurs when the organic matter is completely replaced by minerals and the fossil is turned to stone. This generally occurs by filling the pores of the tissue, and inter and intra cellular spaces with minerals, then dissolving the organic matter and replacing it with minerals. Researchers at UCLA and the University of Wisconsin–Madison have confirmed that microscopic fossils discovered in a nearly 3.5 billion-year-old piece of rock in Western Australia are the oldest fossils ever found and indeed the earliest direct evidence of life on Earth.

Explanation:
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.

When eating food, what anatomical and functional divisions of the nervous system are involved in the perceptual experience?
Answer:
Taste afferents reach the geniculate, inferior petrosal, and plexiform ganglia and then proceed to the brain stem to synapse in the solitary tract of the medulla oblongata. Nerve branches branch from here to the lateral hypothalamus, the amygdala, and the thalamus
Explanation:
The taste sensitivity of the tongue is conveyed by three different cranial nerves (VII, IX and X). The taste buds of the anterior two thirds of the tongue are innervated by the chorda tympani nerve, a branch of the facial. The facial nerve also collects the taste sensitivity of the soft palate through another of its branches, the greater superficial petrosal nerve.At the thalamic level, cross relationships are established with the contralateral gustatory nucleus and convergence with other lingual and olfactory afferences of the piriformis cortex. Third-order neurons are sent from the thalamus to the parietal cortex. Somatosthetic fibers have mainly contralateral projections, while taste projections are ipsilateral.
The sensation associated with taste when eating food is primarily sensed by nerves that are located in the peripheral nervous system (PNS) and they are involved in sensory and somatic functions.
A nervous system refers to a neural network that comprises nerve cells and fibers, which are used for the transmission of neural impulses (signals) around the various body parts of a living organism.
In living organisms, the nervous system is made up of two (2) major components and these are;
Central nervous system (CNS)Peripheral nervous system (PNS)Generally, the peripheral nervous system (PNS) is the anatomical and functional divisions of the nervous system that is responsible for perceptual experience when eating food.
