Answer:To measure the distance of a star, astronomers use a baseline of 1 astronomical unit (AU), which is the average distance between Earth and the sun, about 93 million miles (150 million kilometers). They also measure small angles in arcseconds, which are tiny fractions of a degree on the night sky.

How would you revise the simulation so users can evaluate the role of human activity in the ph of the ocean? need help now!!!
aleksklad [387]

You would revise the simulation so users can evaluate the role of human activity in the pH of the ocean by lowering the temperature.

<h3>What is pH?</h3>

pH may be defined as the power of hydrogen. It determines the acidity or basicity (alkalinity) of any substances under any temperature or pressure.

The role of human activity affects the overall consequences of oceans to a larger extent.

Therefore, you would revise the simulation so users can evaluate the role of human activity in the pH of the ocean by lowering the temperature.

How are human mitochondria inherited? See Concept 15.5 (Page 311) View Available Hint(s) How are human mitochondria inherited? S
mel-nik [20]

Answer:

from the mother only

Explanation:

Maternal inheritance is exhibited by certain organelles such as chloroplasts and mitochondria. Mitochondria are the cytoplasmic organelles present in the eukaryotic cells. Mitochondria exhibit maternal inheritance in humans which means that the egg cells contribute the mitochondria to the zygote. The male gametes, sperms do not contribute mitochondria to the zygote. Therefore, any mutation in the mitochondrial DNA of the egg cell is transmitted to the progeny but the mitochondrial genome of sperms and any mutations in it are not carried to the progeny.
