All of the following are reasons for regulation of gene expression EXCEPT -
Answer:
There are three broad levels of regulating gene expression:
transcriptional control (whether and how much a gene is transcribed into mRNA)
translational control (whether and how much an mRNA is translated into protein)
Explanation:
The first method of controlling transcription is by regulating the quantity of mRNA that can be generated from a given gene, hence option C is correct.
What is gene expression?The level of regulation involves post-transcriptional processes that manage how mRNA is translated into proteins, repair of damaged cells are not controlled by gene expression.
The expression of an animal's genes ultimately determines its phenotype, which is influenced by environmental variables like as nutrition, temperature, oxygen levels, light cycles, and the presence of mutagens.
Therefore, despite the fact that every cell type in your body has the exact same DNA, gene regulation allows for each cell type to have a unique collection of activated genes, hence option C is correct.

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

24. Why is everything in our solar system attracted to the sun? *
a. smallest gravitational attraction in the solar system
b. largest gravitational attraction in the solar system
c. it is equal distance to all the planets
O d. it orbits around the planets
Answer:
B. Largest gravitational attraction
Explanation:
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
I beleive it's B because it would have to be a strong gravitational pull to keep everything balanced correctly.
Please mark me brainliest if correct :)

what are some connections of photosynthesis to the real world?
Answer:
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.

Emily’s friend Mark recently learned that he was adopted; although his parents tried to keep it a secret for as long as possible, he realized that he could not be their biological son because he has brown eyes, a dominant trait, while they both have blue eyes, a recessive trait.
Is Mark correct in assuming he must be adopted because of his difference in eye colour?
Answer:
Explanation:
Two blue eyed parents have a brown eyed baby Although it is uncommon, parents with blue eyes can have children with brown eyes. The inheritance of eye color is more complex than originally suspected because multiple genes are involved.
The pigment plants have that they use for photosynthesis is called _________.
Answer:
chlorophyll
Explanation:
The mechanism by which light energy can be transformed into chemical energy by synthesis of organic compounds is chlorophyll, a member of the most significant pigment class involved in photosynthesis. In nearly all photosynthetic species, e.g. green plants, cyanobacteria and algae, the use of chlorophyll is identified. It consumes light energy and is then used for the conversion to carbohydrates of carbon dioxide.

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.
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.
