describe how lactose undergoes enzymatic hydrolysis by lactase.
Lactose is a dissacharide composed of two monosacharides(glucose and galactose). Glucose and galactose are isomers, which means they have the same molecular formula(C6H12O6) but different structural formulas.
During hydrolysis the bond between the two monosacharides is broken and a water molecule is added.
lactose(C12H22O11)+H2O-->glucose(C6H12O6)+galactose(C6H12O6)
the enzyme that catalyzes this reaction is called lactase and is secreted by the small intestine

Due to the Earth's shape and orientation, areas near the Equator receive the greatest amount of energy from the Sun. Ocean currents
Complete question:
Due to the Earth's shape and orientation, areas near the Equator receive the greatest amount of energy from the Sun. Ocean currents
A. move only away from the equator as a result.
B. help to distribute this energy by warming other regions of the globe.
C. move only toward the equator as a result.
D. keep this energy concentrated in one region of the globe
Answer:
B. help to distribute this energy by warming other regions of the globe.
Explanation:
Heat it gained in equatorial latitudes and lost in higher latitudes. Winds and marine currents redistribute the heat around the earth. The ocean clime is influenced by winds, and show a lower thermic amplitude than continental climes due to a bigger redistribution of heat by the currents.
There exist horizontal water movements that are produced by the action of different winds on the ocean surface. Superficial winds, influenced by the Coriolis effects, are responsible for most of the marine currents.
Trade winds push the water surface forward western direction in the equator, while western winds produce currents that move water to the east at higher latitudes. By the Coriolis effect, water masses are deviated to the west or the east, depending on the hemisphere, and result in large clockwise circular turns in the Northern Hemisphere, and in the opposite direction in the Southern Hemisphere.
Warmer currents travel from the tropics, along the continental margins, carrying warm water to higher latitudes, and as they do so, these water masses get cooler, producing cold currents.
There also exist vertical water movements, such as the ascendant “upwelling” currents that transport cold water with nutrients from the bottom to the surface. Through trade winds at higher latitudes, surface water is diverted out to sea, making a place for the ascent of cold water from the deep. At tropical latitudes, descendent “downwelling” currents occur. Dense cold water from the poles descends as they get in touch with warmer water from lower latitudes.
Answer:
help to distribute this energy by warming other regions of the globe.

Linda is a forensic entomologist. At a crime scene, she notes that there are several Piophilidae, or cheese skippers, on the body. Which stage of decomposition has the body reached? A. protein fermentation B. rigor mortis C. primary flaccidity D. pallor mortis
Answer: Forensic entomologists are the people which in solving the forensic investigations or cases in which they tend to study the life cycle of the insect which is found on the body of the dead person.
Explanation:
There are various stages of decay of body and different life cycle of insects or insects are found at different stages of decay of the dead body.
Out of those, cheese skippers or Piophilidae are found on the stage when there is protein fermentation in the body.
This is advanced stage or we can say later stage as these insects are not interested in the body when it is fresh, it usually appears during the time of protein fermentation.(option A)
Answer:
Forensic entomologists are the people which in solving the forensic investigations or cases in which they tend to study the life cycle of the insect which is found on the body of the dead person.

Study the graph above. What does this graph suggest about the relationship between human population and extinction rate
A)
As human population increases, extinction rates also increase.
B)
Human population is increasing, while extinction rates are decreasing.
C)
In order for the extinction rate to slow, the human population must
increase
D)
There is an inverse relationship between human population and extinction
rates.
Answer:
A
Explanation:
as human population increases so does extinction
The graph shows that there is a direct correlation between the human population and the extinction rate.
Graphical IllustrationFrom the graph, as the population of humans increases, the extinction rate also increases. Similarly, a decrease in the human population also results in a decrease in the extinction rate.
Thus, it can be concluded that there is a direct correlation between the population of humans and the extinction rate as far as the graph is concerned.

If the temperature outside is 35
degrees Fahrenheit what type of
precipitation is likely to occur? Why?
PLZ EXPLAIN WHY
Answer:
Rain: Rain made of liquid water droplets falls when temperatures in the air and at the surface are above freezing (32°F, 0°C).
Explanation:
As average temperatures at the Earth's surface rise, more evaporation occurs, which, in turn, increases overall precipitation. ... In addition, higher temperatures lead to more evaporation, so increased precipitation will not necessarily increase the amount of water available for drinking, irrigation, and industry.
Freezing rain is simply rain that falls through a shallow layer of cold temperatures at or below 0 degrees Celsius (32 degrees F) near the surface. When this rain becomes supercooled, it can freeze on contact with roads, bridges, trees, power lines, and vehicles.

Light material floated up and became the early mantle and crust while iron and nickel pulled to the center of Earth. Which answer uses the word "light" in the SAME way as the sentence above? Group of answer choices A. If the power goes out, they will have to light candles. B. The sudden, bright flash of light woke him up. C. After the injury, she was only able to lift light objects D. Her mother gave her a light kiss before she left for school.
Answer:
C. After the injury, she was only able to lift light objects.
Explanation:
"Light material floated up and became the early mantle and crust while iron and nickel pulled to the center of Earth" In this sentence, the word light is an adjective that means of little weight. Sentence C uses light in the same way because it is referring to objects that are easy to move since they are not heavy.
In option A, the word light is a verb that means to burn a candle to let them see.
In option B, the word light is a noun that is the brightness that allows us to see.
In option D, light is an adjective that modifies the noun kiss. It describes a delicate, small kiss.
The main organic source of energy for living things is
Answer:
The Sun
Explanation:
Nearly everything eats sunshine – or eats something else that ate sunshine. The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter.

Which mutation would NOT cause a change in an organism's phenotype?
Answer:
B)TAT becomes TAC
Explanation:
since thymine(T) pairs with adenine(A), thymine(T) is replaced with uracil(U) in the RNA and guanine(G) pairs with cytosine(C)
we can find the complementary codons for each strand
the codon for TAT is AUA which codes for methionine
the codon for TAC is AUG which also codes for methionine
that means the phenotype (methionine)remains unchanged for different genotypes(TAT and TAC)
Answer:
A silent mutation does not produce a phenotype change. Explanation: In point mutations, a base pair of the DNA sequence is altered.

Which of the following would be the correct mRNA sequence for the DNA of the light colored moths...
Answer:
There are no options but the question can be answered based on general understanding. The mRNA sequence is:
CGU AGG CUU AGC
Explanation:
Transcription is the process by which DNA template is used to synthesize a mRNA sequence. The transcription process, which occurs in the NUCLEUS, follows the complementary base pairing rule, which states that an Adenine will always pair with Thymine (Uracil in RNA), while the Guanine will always pair with Cytosine i.e. A-U, G-C.
According to the image in this question, it shows the DNA sequences of a light and dark colored moth (mutant). The DNA sequence of the light colored moth is as follows: GCA TCC GAA TCG.
Using the priniples of complementary base pairing, the mRNA sequence of this DNA template will be: CGU AGG CUU AGC
