How does mantle convection cause seafloor spreading?

Biology
1 answer:
Julli [10]3 years ago
8 0

Answer:

Mantle convection is the slow, churning motion of Earth's mantle. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

What process occurs in prokaryotes but not in eukaryotes?
Naddika [18.5K]

Explanation:

In the given question, the options are not provided in the question and neither they are found anywhere therefore based on the previous knowledge this can be answered.

Since both the prokaryotes and eukaryotes are living therefore they perform the metabolism or chemical reactions in the form of process.

Both eukaryotes and prokaryotes perform almost similar process like the cellular respiration, photosynthesis by green colored organisms, the Central dogma related process like the replication, transcription and translation.

The central dogma related processes differ in these process only in terms of the site they are performed and a few modifications which are characteristics of the eukaryotic cells.

In prokaryotes, the transcription and translation are coupled and takes place in the cytosol whereas in eukaryotes transcription in the nucleus and translation in the cytosol.

Also in eukaryotes, modifications like the splicing, alternative splicing, capping and tailing are observed which are not observed in the prokaryotes.

When acetylcholine binds to receptors at the motor end plate, the end plate membrane becames:__________a. repolarized. b. more p
sladkih [1.3K]

Answer:

d. more permeable to sodium ions.

Explanation:

The binding of Acetylcholine  with the receptors at  motor end plate facilitate   membrane permeability to sodium ions therefore  opening of voltage gated channels for sodium ions.

Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.

If  the  stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the  synapse to depolarize the membrane with  reversal of charges to generate action potential.

The continuous  binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization.  Acetycholinesterase enzymes breakdown Acetycholine to choline  and Acetyl Co -A. These are recycle back to Acetycholiine
