Answer:

- binary stars

Explanation:

A binary star is a star system. It is composed of its stars that orbit the same center of mass, that is, orbit around each other.

If two stars orbit each other, but maintaining a great distance from each other, they evolve independently and are called a separate pair. If they are close enough for matter to transfer between them due to tidal forces, they are called close pair or contact.

Binary stars obey Kepler's Laws of Planetary Motion, which are three:

1st law (law of orbits): Each star moves along an elliptical orbit, with the center of mass of the system at one of the foci of this ellipse.
2nd law (law of areas): the line connecting one star to another scans equal areas at equal time intervals.
3rd law (harmonic law): The square of the orbital period of the stars is proportional to the cube of their average distance to each other.

A stem growing up and out of the soil, away from gravity is an example of a _______.

Tomtit [17]

A tropism is a movement of an organism toward or away from a stimulus. A positive tropism is when the organism moves toward the stimuli. A negative tropism is when the organism moves away from the stimuli. So, your answer will be negative tropism, since the stem is growing up and out of the soil, AWAY from gravity.

Enzyme hot spring graphing what enzymes probably came from the digestive tract of the mondoni

AURORKA [14]

I found the full exercise on the internet and it describes that there are three enzymes and you want to know which are the two enzymes from the digestive tract of the mondoni and which one is the enzyme from a hot spring.
Attached are two graphs from the analysis of the activity of these enzymes regarding temperature and pH. I found these graphs with the full exercise.
The enzymes that probably came from the digestive tract of the mondoni were enzymes A and B. These enzymes were resistant two lower levels of pH which indicates that they could be present in a digestive tract, which tends to be acidic, while the enzyme C does not tolerate lower pH levels. Enzymes A and B were also more active when in lower temperatures that match temperatures of a normal living organism, whereas enzyme C was more active in higher temperatures matching its probable provenience - a hot spring.
