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.

How was life today similar and different to the Silurian period? ( animals, plants , organisms)

Answers

Answer:

The creatures developed in silurian period have evolved to live in sea bottoms.

Explanation:

Silurian life that is marine benthic which are bottom lying organisms belongs to the community of ecological zones that express themselves. As the gradients of temperature, pressure, and salinity. Consists of a community that is adapted to live in a darker region, used to lie in quieter environments that are in deep offshore water. These are much like the reef communities today as they do not tolerate excessive sediments. Prefer wave water that is shallow than 30 meters. These platforms are very gentle and are found over a hundred km gradients. Most of the fish represent the Silurian age and are widely distributed in marine environments. Examples of jawless fish, terrestrial fungi etc.

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.

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
