Answer:
Each constellation is a region of the sky, bordered by arcs of right ascension and declination. ... Together they cover the entire celestial sphere, with their boundaries adopted officially by the International Astronomical Union in 1928 and published in 1930.
So I would say its A : Boundary
Explanation:
- Eijiro <3
Love the pfp by the way! :D
The International Astronomical Union (IAU) defines a constellation by its boundary. The correct option is A.
What is International Astronomical Union?In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.
The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.
The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.
Thus, the correct option is A.

A small crab will make its home inside a mussel, obtaining food and shelter while the mussel simply tolerates the situation. In contrast, a different crab falls victim to an intruder who slowly extracts nutrients from its body by spreading a fungus-like substance throughout its extremities.

Earthquakes and faults form at __________ boundaries.
transform
convergent
divergent
Answer:
transform
Explanation:
Most earthquakes occur at the boundaries where the plates meet. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones, transform faults, and subduction zones.

What is the correct mRNA transcription of the following DNA sequence? ATGGCACCTTAC
A. UACCGUGGAAUG
B. AUGGCACCUUAC
C. CAUUCCACGGUA
D. CATTCCACGGTA
The process of transcription produces the mRNA sequence from the DNA. The mRNA transcription of ATGGCACCTTAC will be UACCGUGGAAUG. Thus, option A is correct.
What is mRNA transcription?Transcription is the process of the formation of mRNA from the replicated DNA strand of the cell. It produces an mRNA transcript that is a single strand and further codes for amino acids.
The mRNA transcript forms by the base pairing with the DNA template. If the DNA sequence is ATGGCACCTTAC then according to the base pairing rule the adenine (A) pairs with uracil (U) in mRNA, and guanine (G) pairs with cytosine (C). In mRNA, the adenine binds with uracil and not thymine, and hence A pairs with U, whereas the G-C bond remains the same.
The DNA strand: ATGGCACCTTAC
The mRNA sequence will be: UACCGUGGAAUG
Therefore, option A. UACCGUGGAAUG is the mRNA transcript.

Answer:
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.
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.
