Answer:

D) arteriosclerosis

Explanation:

  • Arteriosclerosis refers to the thickening and hardening of walls of the arteries.  In simple words it is the stiffening of the artery walls.
  • Arteriosclerosis is caused by high blood pressure, high cholesterol levels or smoking, which damages the arteries causing the formation of plaques.
  • Formation of plaques makes arteries to thicken and stiffen thus restricting the flow of bloods to organs and tissues in the body.

Which of the following statement(s) are true with respect to graded potentials?a. A graded potential has a threshold Graded pote
puteri [66]

Answer:

Following statements are correct

A graded potential has a threshold Graded potential amplitudes decay over distances

Graded potentials can summate in space and time

Graded potential amplitude increases with stimulus strength

Explanation:

Graded potential is generated in a neuron when ions enter or exit through the ligand gated channels. In general, this potential decreases with time before reaching axon. Signals that reach the graded potential, determine whether the amplitude of the potential will reach the threshold and hence causes action potential. Graded potential travel only over a short distance and is either depolarization or hyperpolarization. Their strength reduces with time as the charged ions move out of the membrane. They summate temporally or spatially

Graded potentials spread by passive means i.e spreading electronically to neighboring membrane regions.

Hence, the correct statements are

A graded potential has a threshold Graded potential amplitudes decay over distances

Graded potentials can summate in space and time

Graded potential amplitude increases with stimulus strength

These question all about ice storms!!!!!!!! answer them in complete sentence
Arisa [49]
The scale used to measure the intensity of ice storms is called the Sperry–Piltz Ice Accumulation Index, <span>based on the expected footprint of an ice storm, the expected ice accumulation as a result of a storm, and the expected damage a storm inflicts on human-built structures.

Meteorologists use Dual Polarization Radar, and the Q2 a mix of sensors and algorithms to predict precipitation.

Yes ice storms can be predicted by weather agencies, and it depends how fast it is detected and how severe it is.
