Hyperpolarization means that the ________. Group of answer choices membrane potential becomes more negative than the resting pot
gladu [14]

Answer:

Hyperpolarization means that the membrane potential becomes more negative than the resting potential.

Explanation:

The voltage across the membrane of a neuron that is at rest and not sending out signals is called the resting membrane potential, or just the resting potential. The concentration gradients of ions across the membrane and the amount of each type of ion that can pass through the membrane determine the resting potential. When a neuron is at rest, there are different levels of sodium and potassium on both sides of the cell membrane. Ions move down their gradients through channels. This creates a difference in charge, which gives rise to the resting potential.

When the membrane potential at a particular location on the neuron's membrane gets more negative, this phenomenon is known as hyperpolarization. Depolarization, on the other hand, occurs when the membrane potential becomes less negative (more positive). Both depolarization and hyperpolarization can take place as a result of the opening and closing of ion channels in the membrane, which changes the rate at which certain types of ions can enter or leave the cell.

Why are biologists still debating the classification of protozoans
e-lub [12.9K]

The biologists have categorized protozoans as a part of Kingdom Protista, they have attempted to sort protists in comparison to three of the other kingdoms, that is, animals, plants, and fungi. However, this has not worked as several of the protists demonstrate features from two or more of these kingdoms.  

The protozoans show considerable diversity, that is, some live as predators, some as parasites, and some others are thriving as producers. Scientists have attempted to categorize the organisms within the protists as either fungus-like, plant-like, or animal-like.  

However, close testing and genetic examination have shown that these classifications often does not imply.

Human blood groups are governed by three alleles, IA, IB, and i. IA and IB are codominant and i is recessive to both. A man who
tangare [24]

Answer:

The correct answer is e. all of the above

Explanation:

A person can only have two allele of a character, therefore, the genotype of a male parent can be IBIB or IBi and the genotype of female parent can be IAIA or IAi. Therefore during gamete formation, all allele will segregate and assort independently.

So all the possible combinations are possible that are  IAIB, IAi, IBi or ii because all the allele can be present in the two parents in which one have A blood group and another have B blood group.

Therefore their children could have A, B, AB, or O blood group so the correct answer is e. all of the above.
