Prokaryotic cells lack a defined nucleus, but have a region in the cell, termed the nucleoid, in which a single chromosomal, circular, double-stranded DNA molecule is located.

In the formula, E K = 1/2 • m • v 2 if mass (m) was doubled, how much would kinetic energy
Viktor [21]

Answer:

mass doubled makes KE twice as large

velocity doubled makes KE 4 times as large

Explanation:

Try it with an example

m = 4

v = 8

KE = 1/2 m * v^2

KE = 1/2*4 * 8^2

KE = 1/2 * 4 * 64

KE = 128

Now double the mass

m  = 8

v = 8

KE = 1/2 8 * 8^2

KE = 1/2 8 * 64

KE = 4 * 64

KE = 256 double what it started out as.

Now do it again.

m = 4     That was the original mass

v = 16

KE = 1/2 4 * 16^2

KE = 2 * 256

KE = 512

When the velocity is doubled the KE becomes 4 times as big.

4*128 = 512

Where are glaciers found select 3 opt
kotegsom [21]

Answer:

Glaciers will only form under certain conditions and in specific environments. A cold climate and sufficient moisture in the air for the precipitation of snow are both necessary factors that permit at least some snow to last year-round. This allows for the build-up and compaction of snow that will eventually become glacial ice. Sufficiently cold climate conditions exist at high altitudes and high latitudes.

Explanation:

There must be landmasses at high latitudes for continental glaciers to occur, as they cannot form over open water. While persistent sea ice can and does form, because it floats, it does not flow as a glacier does.

Which structures that distinguish a eukaryotic cell from a prokaryotic cell are part of the internal membrane system?
Nat2105 [25]

Answer:

nuclear membrane, endoplasmic reticulum, Golgi apparatus, and vesicle

Explanation:

The structures or organelles in internal membrane system in the cell do all production, processing and secretion function together. A prokaryotic cell does not contain any membrane bound organelles but Eukaryotic cells do have. Nuclear membrane has double membrane and golgi-rendoplasmic reticulum and vesicle contain single membrane so all these organelles are membrane bounded.
