Soil is made up of air, water, minerals and organic material and is one of the most important natural resources on earth. Most life on earth depends on soil as a direct or indirect source of food. Plants and animals source their nutrients from the soil and it is home to many different forms of life.

Explain how Charles Darwin’s theory of natural selection would account for evolution of populations. Use the following terms in

vovikov84 [41]

Explanation:

charles darwin proposed thoery of natural selection.he had collected imnumerable specimens of plant and animals.he published concept survival of fittest. while explaining he says that There is always competition for food.only those organism survive which shows adptations in various reasons. it thoery of natural selection.

There are some objections,

1. natural selection is not only factor responsible for evolution.

2. darwin did not mention uesful and useless modifications.

3. There is no explanation about slow and abrupt changes

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.
