When you did some experiments and picked out a bunch of random stumpy-tailed cats and mated them, they had some stumpy-tailed kittens and some regular-tailed kittens. You did the same with the the regular tailed cats, but they always had only regular tailed kittens. What does this tell you about the genotype of the regular tailed cats

The International Astronomical Union (IAU) defines a constellation by its:

boundary

star pattern

Greek name

Answers

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.

Using the diagram above, answer the following questions: 6. True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false. 7. True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false. 8. Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected? 9. Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected. 10. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.

Answers

FALSE. The factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energyarrow E represents cycling of carbon from living organisms to non-living organisms. this is because it is showing conversion of a carbon from the dead tree to fossil fuel.Its true because the arrow letter A uses the of solar power from the sun then makes a chemical reaction to make food for the plant so basically photosynthesis. The arrow C represents the emission of carbondioxide in the atmosphere. As you can see that the arrow is from the smoke that is emitted from the factories and industries and to the carbondioxide in the atmosphere.All the arrows in a combined form are used to show the biogeochemical cycle or the carbon cycle. In this cycle, carbon is cycled between the biotic and abiotic component of the biome. In any biogeochemical cycle, mas and energy are always conserved.

Is enzyme substrate complex concentration the product of enzyme concentration and substrate concentration?

Answers

Answer:

Yes

Explanation:

The enzyme substrate complex may be defined as the enzyme when interacting with the substrate at an active site and it produces a new product in the process. It is temporary molecule formed when the substrate comes in contact with the enzyme.

An enzyme is the molecule of a protein which acts like an organic catalyst and a substrate is a the molecule which interacts with the specific enzyme to form a product.

Therefore, the enzyme substrate complex concentration is the product of the substrate concentration as well as the enzyme concentration.
