Silvia has blond hair, even though her mother and father each have brown hair. What do we know about Silvia's parents? At least
Svetradugi [14.3K]

Answer:

Each of her parents must have one recessive gene for blond hair color

Explanation:

  • Blond is a recessive trait
  • Since Silvia is blond this means she has both copies of the recessive gene for hair color
  • Therefore, both her parents have a recessive gene for blond hair and passed it down to her.
  • The parents don't have blond hair because their dominant gene for browns masks the recessive gene for blond.

During the course of an action potential, the membrane potential rapidly rises and reaches a peak of about +40 mV before falling
ad-work [718]

Answer:

A)  A decrease in Na+ permeability, and an increase in K+ permeability.

Explanation:

When the potential action reaches a peak of about +40 mv Na+ channels are open and a high number of Na+ ions are entering the inside of the cell. Shortly after this happens the K+ channels will start to open their gates increasing the cell  K+ permeability  while the Na+ channels will start to close their gates, so the Na+ permeability will decrease. This happens  in order to valance the positive charge on the inside of the cell. Normally the inside has a negative charge while the outside has a positive one, as the inside is more positive due to the increase in Na+ permeability at the beginning of the potential action, K+ cations (which are in abundance in the cell) will have to go out through the K+ channels  so as to restore the charge valance, that means that there is an increase in K+ permeability.

As a character of all living things, homeostasis relates most directly to which of the following biological themes
Novosadov [1.4K]

Explanation:

As a characteristic of all living things, homeostasis relates most directly to which of the following biological themes?

A.) Interacting systems.

B.) Stability.

C.) Evolution.

D.) Scale and structure.

Correct: B.) Stability.

During homeostasis the body maintains a constant internal balance (stability) in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis.

Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

Generally describe what forces ultimately shaped the earth into its modern form
Trava [24]

The force of gravity is a major force that created the earth.  As rocks and ice clumped together as they spun around the newly formed star (sun), the force of gravitational pull increased and attracted more debris (rocks and ice). The clumps of rocks, debris, and ice, therefore, grew into a planet.  

Another is electromagnetic force. The spinning currents in the outer core of the earth create a dynamo effect that forms a magnetic field around the earth. This shields the earth from the solar storms of the sun hence protects life and the atmosphere.

Weak nuclear force is responsible for maintaining the heat of the earth’s interior which is critical for maintaining the dynamo  effect of the outer core so the earth is protected by its magnetic field.
