Can anyone explain to me the "all or nothing law" of action potentials? I'm in a college physiology class, and I do not understand this concept.

Answers

Answer 1

Answer: The all or nothing law of action potentials mainly talks about how the axons in the neurons only fire when there is enough action potential to fire. If there is not enough action potential, then the neuron will not be able to send signals because the action potential does not fire because of the deficit.

Photosynthesis plays an important role in supplying energy to living things. Considering what the products of photosynthesis are, What is another way in which photosynthesis is vital to life?

Chlorophyll traps _____ from sunlight.a. oxygen
c. hydrogen
b. energy
d. glucose

Answers

The correct answer is b - energy

Chlorophyll is a green pigment that has light absorbing ability. Light from the sun contains energy in the form of photons.

The photons are trapped by chlorophyll and are used to provide power to split water molecules in the leaf in the process of photosynthesis.

Because chlorophyll is a pigment that absorbs light, it is called a photoreceptor. By absorbing light energy, chlorophyll is vital in the photosynthesis and without it, green plants would not be able to get power to run photosynthesis.

Hypothesize whether prokaryotic cells might have been symbiotic before the evolution of eukaryotic

Answers

Two prokaryotes turning into a eukaryotic cell began with a process called

endosymbiosis. One large prokaryote engulfs (a process called

endocytosis) one small, aerobically respiring prokaryote. The small

prokaryote turned into a membrane-bound organelle, which prokaryotes do

not have, and like we know, only eukaryotes have membrane-bound

organelles. So that is how the eukaryotic cell structure evolved from

prokaryotic cells, meaning that before this evolution, they were most likely symbiotic.

Which of the following describes light as a wave?Light is a transverse wave.

Light is a wave but does not have frequency as a property.

Light is exactly similar to water and sound.

Light is a converse wave.

Answers

Light is a transverse wave and this is what describes light as a wave. The correct option among all the options that are given in the question is the first option. Light is not at all similar to water and sound. It would be a big mistake to consider light as similar to the mediums water and sound. I hope the answer helps.

Answer:

Light is a transverse wave.

Explanation:

Light is a transverse wave. Its particles vibrates or oscillates in the direction perpendicular to the direction of propagation of wave.

Light wave also have both electric and magnetic field component. So, light waves are also called as electromagnetic wave. Another type of wave is longitudinal wave. In this type, the particles of wave are in the direction of propagation of wave.

Hence, the correct option is " light is a transverse wave ".
