Sodium and potassium ions move in and out of the axon when the membrane is ______

Biology
1 answer:
Ostrovityanka [42]3 years ago
7 0

Answer:

Answer : Depolarized

Explanation:

Sodium and Potassium ions tend to move inside of the axin when the membrane is depolarized.

A change in polarity occurs in the axon membrane when a nerve impulse travels across it.  At the beginning of an action potential or nerve impulse , the ions of sodium tend to move inside of axon causing depolarization. As a result potassium ions tend to move outside of the axon causing re polarization. Hence, this effect causes the nerve impulse to travel in one direction only inside the axon.

What is an effect of adaptive radiation?
Vlad [161]

Answer: B! Many new species form.

Explanation:

Adaptive radiation refers to the process by which animals diversify rapidly from the ancestral species into different forms especially when resources are abundantly available. The effect of adaptive radiation is the emergence of new species, which exhibit different morphological and physiological traits.

What are the four types of tissues found in the human body and what are the primary functions of each one.?
deff fn [24]
Epithelial, muscle, connective, And nervous.
epithelial covers the body surface, connective tissues support and protect (serve many functions) the nervous tissues receive stimuli while alsoconduction to and from all over the body, lastly muscle tissues.

muscles tissue consist of three types :/
skeletal, smooth and cardiac. skeletal muscle is use to help contract the skeleto., the cardiac muscle is found within the heart, and the smooth muscle is found in the walls of internal organs and blood vessels

HOME › ASSIGNMENTS ► ASSIGNMENT -<br> Asexual versus Sexual Reproduction 3
nexus9112 [7]

The fusion of two parents' genetic material is understood as sexual reproduction while asexual reproduction yields genetically similar offspring to the same parent.

<u>Asexual Reproduction:</u>

This way all the prokaryotes and other eukaryotes produce offspring. There are a variety of different asexual reproductive practices. These comprises of binary, fragmentation, and budding fission.

  • The binary fission appears when a parent cell wants to split into 2 separate daughter cells of the same diameter. For an instance, protozoa reproduces in the same way.
  • Fragmentation happens when a parent entity divides into small parts or fragments, and each segment grows into a recent organism. Starfish, that way replicate.
  • Budding happens when a parent cell develops a bud close to a bubble. When growing and developing, the bud remains connected to the parent cell. This get detached from the parent cell when the bud is completely grown, and becomes a new entity. It is common in hydra and yeast.

<u>Sexual Reproduction:</u>

  • A reproductive process which comprises haploid female gamete fusion, i.e. egg cell and haploid male gamete i.e. sperm cell.
  • That implies they only include half the number of chromosomes contained in other species cells. A form of cell division named meiosis creates gametes.
  • These gametes are fused at fertilization which results in the production of a diploid zygote having the chromosome double of gametes.
