Please help!! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line to figure out how many kilo

meters a plate moved from the spreading boundary in a set number of years. Convert that rate to the distance a point moves in just one year, rounding your answer to the nearest millimeter.

Answer:

R = 16mm/y  

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t  

To calculate it in millimeters per year we need to convert it:

<em>1 km = 1000 m  </em>

<em>1 m = 100 cm </em>

<em>1cm = 10mm </em>

<em>1 km = 1,000,000 mm   </em>

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

Can someone please help me answer questions 16-20 please. Thank you!!
torisob [31]

Answer:

16) 6 electrons

17) 6 protons

18) 6 neutrons

19) 4 electrons

20) 6

Explanation:

There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.

The protoplasm and cytoplasm of a plant are interchangeable terms.TrueFalse
Svetllana [295]
No, they are not interchangeable because p<span>rotoplasm is the living content of a cell that is surrounded by a plasma membrane (cell membrane). Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macro-molecules such as nucleic acids, proteins, lipids and polysaccharides. In eukaryotes the protoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm. </span>

What characterizes a biome
goblinko [34]
A BIOME is a major ecosystem spread over a wide geographic area, and characterized by certain types of flora and fauna, as determined by climate. Climate and soil determine the flora, which, in turn, largely determine what type of other organisms live in that biome.
