Answer:
more saliva (spit) would come in your mouth
Answer:
If you place a small piece of a salted cracker on your tongue, the salty flavor would increase the amount of saliva in the mouth. Salivary amylase degrades the starch from the cracker into glucose. The salty flavor will increase the salivary amylase in the mouth.

Explanation:
Explain the relationship between DNA, mRNA, and protein
Answer: In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. ... The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein. Figure 2: The amino acids specified by each mRNA codon. DNA is the genetic code that stores the instructions to make a protein. mRNA is involved in reading DNA, in a process known as transcription. This mRNA is then processed b ribosomes to make proteins. The sequence of DNA determines the codons in mRNA, which determines the sequence of amino acids, which determines the protein being made.

Based on the data shown in the graph, which of the following best describes how ecologists could determine when this ecosystem is approaching a climax community?
A
Determine if the keystone species in the ecosystem is present two years after the volcanic eruption
B
Measure the biomass of the pioneer species present before and after the volcanic eruption
(C
Record the number and type of producers present every year after the eruption
D
Calculate the net primary productivity of a specific indicator species every year after the eruption
Scientists can tell that an ecosystem's climax is approaching when they record the number and type of producers present each year after the eruption, as shown in option C.
We can arrive at this answer because:
An ecological community reaches its climax when it reaches its last stage of ecological succession.At this stage, animals and plants are well developed and interact in a balanced way.Thus, the ecological region must have a considerably high number of producers, as it shows that the basis for interactions between living beings is well established.Thus, scientists must observe the number of producers that settle in each ecological succession, to be able to determine when the community is close to its climax.

Answer:
That scrape on our knee will never heal and the blood loss due to bleeding will never be replaced. This is because RNA is inside of cells and without the ability to create new RNA you cannot replace missing cells. So the scrape will never heal if your cells cannot create new RNA.

How does matter and energy cycle through the living and nonliving parts of an ecosystem? In five sentences, please.
Matter and energy cycle through the living and nonliving parts of the ecosystem in the form of chemical compounds. Some chemical compounds make up living organisms that are called 'organic compounds'. Chemicals in the ecosystem are recycled. Some of the organic compounds of living organisms are returned to the ecosystem. Some of the organic compounds make up dead organisms. Some organic compounds are returned as nutrients to the ecosystem. Dead producers and consumers provide matter and energy to decomposers. Dead decomposers recycle dead matter, and the dead matter is returned to the ecosystem. All matter and energy are then returned to the ecosystem in one way or another. The matter and energy of the ecosystem can be recycled indefinitely because it is constantly being produced and consumed.

what is the main enzyme used during transcription?
Answer: RNA polymerase
Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. Transcription factors can bind to specific DNA sequences called enhancer and promoter sequences in order to recruit RNA polymerase to an appropriate transcription site.
Briefly describe the function of polymerase chain reaction (PCR)
Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest.

Answer:
carbohydrates
Explanation:
Sugar units are the building blocks of all carbs. Simple sugars (monosaccharides and disaccharides) and complex carbohydrates (polysaccharides, which are polymers of simple sugars) are the two forms of carbohydrates.
Carbohydrates are one of biology's most researched macromolecules. They produce glucose, or "blood sugar," as their fundamental energy unit, whether simple or complicated. Furthermore, both simple and complex carbohydrates are made up of chains of glucose molecules at their most fundamental level.

Carbohydrates are made of simple and complex sugars.
What are carbohydrates?Carbohydrates, also known as carbs, are vital at every stage of life. They're the body's primary source of energy and the brain's preferred energy source.
Moreover, carbs are broken down by the body into glucose – a type of sugar. Glucose is used as fuel by your body's cells, tissues, and organs.
Carbohydrates are found in a wide array of both healthy and unhealthy foods—bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pie. They also come in a variety of forms. The most common and abundant forms are sugars, fibers, and starches.

5. Identify the most likely location for an Earthquake of high magnitude. *
1 point
Oceanic-Oceanic, Divergent Boundary
Oceanic-Continental, Convergent Boundary
Oceanic-Oceanic, Transform Boundary
Given what we know about the mechanisms that create and cause earthquakes of varying magnitudes, we can confirm that the most likely location for an Earthquake of a high magnitude is an "Oceanic-Oceanic Transform Boundary".
As stated, a transform boundary, also often referred to as a strike-slip boundary or just simply transform fault, is a fault where the plates that comprise it move mostly in a horizontal manner along the plates boundary. They are often linked to subduction zones, ridges, or other transform faults, where they end in an abrupt fashion.
History has shown that the greatest earthquakes recorded have formed along one of these transform boundaries. The most powerful earthquake zone on earth, in a historic sense, is the circum-Pacific seismic belt or "Ring of fire". This transform boundary alone is responsible for roughly 81% of the world's largest earthquakes.

Based on the genetic code chart above, which of the following would be the result of this single base-pair substitution?.
The nonsense mutation is a point mutation that originates a new stop codon within the sequence. The result of this single base-pair substitution is A nonsense mutation resulting in early termination of translation. OPTION E
------------------------
When a change occurs in a single base pair, it is known as a point mutation.
Points mutations might be either silent, missense, or nonsense.
In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. If the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation. Finally, if the mutation causes the mRNA codon to be a stop codon, we are referring to a nonsense mutation.In the exposed example,
30 31 32 33 34 35 36 37 38 39
Original sequence G C U A U U A A C A
Mutated sequence G C U A U A A A C A
The mutation occurs in base number 35. An adenine replaces the original uracil.
Since only a single base changes, this is a point mutation.
This point mutation originates a new stop codon, which places before the stop codon of the original sequence (UAG) .
We are referring, then, to a NONSENSE MUTATION.
The options are:
A. a silent mutation (no change in the amino acid sequence of the protein)
INCORRECT. It is not a silent mutation
B. a frameshift mutation causing extensive change in the amino acid sequence of the protein
INCORRECT. It does not extensive change in the amino acid sequence
C. a missense mutation causing a single amino acid change in the protein
INCORRECT. It is not a missense mutation.
D. a frameshift mutation causing a single amino acid change in the protein
INCORRECT. It is not a frameshift mutation.
E. a nonsense mutation resulting in early termination of translation
CORRECT. The change of a single base produces a new stop codon placed before the original one.
The result of this single base-pair substitution is A nonsense mutation resulting in early termination of translation. OPTION E
