Answer: star
Exoplanets are the planets present in the other star system. There are billions of stars in our galaxy and we expect presence of other planetary systems similar to our solar system. Exoplanets can be detected by a) radial velocity method b) astrometric method c) transient method. In the radial method, we observe the changes in the spectrum of the light coming from star when an exoplanet is orbiting it. There is change in gravitational pull as the planets goes around the star. It sometimes pulls into smaller orbit. like this the star wobbles back and forth. By measuring the blueshift and redshift in the star's spectrum, exoplanet can be discovered.

Hello!
I'm going to have to infer that you meant "grams" and not "gallons" :-)
Anyways, to find the density, you need to the divide mass over volume (d = m/V).
Since we are given the volume being 15.0 mL, and the weight being 40.5 grams, we can find the density of the aluminum block.
40.5 grams / 15.0 mL = 2.7 g/mL
Therefore, the density of the aluminum block is 2.7 grams per milliliter.
Answer:
The correct answer is A: Hypertonic solution
Explanation:
Syrup is a solution with a <u>high concentration of sugar</u>. When you put the fruit in this solution, the syrup concentration is higher than the sugar concentration inside the fruit, this is called an <u>hypertonic solution</u>. Consequently, there is a gradient of concentration between the interior of fruit cells and the exterior. The water will go out from the cells towards the exterior, in favor of the concentration gradient. In this way, you are removing water from inside the fruit (drying).
Not sure but Maybe a “value and a unit”
