What is the major cause of changes in gene expression?

Answers

Answer 1

Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions by adjusting the amount and type of proteins it manufactures.

Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:

Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:The United States uses many different energy sources and technologies to generate electricity. The sources and technologies have changed over time, and some are used more than others. The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.

What type of succession starts with some soil but then goes through the 10p
steps of succession?

A. Primary Succession
B. Secondary Succession
C. Climax Community

Answers

Explanation:

Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.[1]

Succession after disturbance: a boreal forest one year (left) and two years (right) after a wildfire.

The community begins with relatively few pioneering plants and animals and develops through increasing complexity until it becomes stable or self-perpetuating as a climax community. The "engine" of succession, the cause of ecosystem change, is the impact of established organisms upon their own environments. A consequence of living is the sometimes subtle and sometimes overt alteration of one's own environment.[2]

It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe landslide, or by some form of disturbance of a community, such as from a fire, severe windthrow, or logging. Succession that begins in new habitats, uninfluenced by pre-existing communities is called primary succession, whereas succession that follows disruption of a pre-existing community is called secondary succession.

Succession was among the first theories advanced in ecology. Ecological succession was first documented in the Indiana Dunes of Northwest Indiana and remains at the core of much ecological science.[3]

Answers

Answer:

The correct answer would be - AUGCUUAUC

Explanation:

The new mRNA strands are made by the process called transcription that involves an enzyme that helps to copy a segment of DNA or gene to produce a new RNA strand that encodes for the protein. In this process, a new RNA strand copied the complementary to the sequence of DNA strand. It means adenosine is copied into its complementary form uracil in RNA, Thymin to adenosine, cytosine to guanine and guanine to cytosine.

Original strands: TACGAATAG

new RNA strand: AUGCUUAUC

What are new stars that are found in the spiral arms and formed from recycled dead star material known as?

population II stars

red dwarf stars

population I stars

brown dwarf stars

Answers

Answer:

population I stars.

Explanation:

A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.

It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).

The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.

Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.

New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
