Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.

Which of the following would be the correct mRNA sequence for the DNA of the light colored moths...​

Answers

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

Which mutation would NOT cause a change in an organism's phenotype?

Answers

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.

what kind of authority does our elected government officials exercise?​

Answers

Answer:

Depending upon the country and community in which you live, the authority exercised by elected officials is defined by formal rules and informal norms of behavior that apply in that jurisdiction. Authority is the willing compliance, almost automatic, with dictates from figures to whom we grant that authority. The formal rules limiting government officials’ authority should protect citizens from abuses of that authority but informal norms may sometimes allow elected officials to get away with actions that violate those rules or, at least, bend them to their own purposes.

Rational- legal authority is practiced by elected government officials. The

practice of the people voting the officials they deem fit is referred to as

Democracy.

Democracy involves leadership of the people through laws which govern

that area. The laws  are referred to as constitution and contains the power

and authority that government officials and says what can be done by them

or not with laid down consequences if disobeyed.

This however helps to put office holders in check as no one is above the

law in order to prevent anarchy.

Due to the Earth's shape and orientation, areas near the Equator receive the greatest amount of energy from the Sun. Ocean currents

Answers

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.

Answers

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 Illustration

From 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.

PLZ EXPLAIN WHY

Answers

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.
