Compared to unmyelinated axons, myelinated axons?

Biology
1 answer:
Furkat [3]3 years ago
4 0

Answer:

A. Conduct impulses faster.

Explanation:

Myelinated axons are called that way due to the myelin sheath that surrounds them. Myelin has an insulation property so electrical impulses cannot travel through it, except on certain sites called Nodes of Ranvier. In order for electrical impulses to be conducted on myelinated axons they must "jump" from one Node of Ranvier to the next, and thus conduction is faster. This is called saltatory conduction.

The energy in fossil fuels is derived from the energy stored in plant and animal matter
timofeeve [1]
<span>The energy which we are using in today's world for our needs is fossil fuel, we used to power our home by burning coal and run our vehicle through the oil or fossil fuel, but we should know that it is limited in quantity and cannot use it once it releases energy or burned, it is created by the dead organic materials like trees and animals etc. which slowly buried in the ground as the time goes and after 1000's of years it get pressurised and rise in temperature make that organic material into fossil fuel, so that's how the fossil fuel comes in existence, which we extract from the ground by drilling deep into the ground.</span>

The rate of a physical or chemical process
Nady [450]

Answer:

(A) rate=

Sp

Ss

st

Explanation:

The rate of chemical is a measure of the speed of a chemical reaction.

The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.

Reaction rate is usually expressed in terms of a change in concentration of the chosen reactant or product per unit of time.

During a reaction, the concentration of the reactant decreases exponentially with time while that of a product increases exponentially with time.

Reaction rate  = \frac{change  in concentration of a reactant/product}{Time taken}

Pls hurry im doing an exam Four groups of students plan scientific investigations to answer four questions for the science fair.
mafiozo [28]

Answer:

The correct option is 3

Explanation:

An experimental investigation would require an hypothesis, aim, methodology, results, discussion and conclusion.

The third option can be easily answered using the "requirements" above.

The hypothesis (null hypothesis) would be different types of grass do not affect how far a ball rolls

The aim would be to determine the effect of different types of grass on the movement of a ball

The methodology would involve identifying several playing grounds with different grasses and then rolling the ball with a constant force on the different grasses and then determining the eventual speed and distance traveled by the ball on those grasses which would serve as the results. Inferences can then be made from this results and then conclusions drawn subsequently.
