What is indicated by the arrow?

An arrow is a graphical symbol, such as ← or →, or a pictogram, used to point or indicate direction. In its simplest form, an arrow is a triangle, chevron, or concave kite, usually affixed to a line segment or rectangle, and in more complex forms a representation of an actual arrow (e.g. ➵ U+27B5).

What do these four elements have in common?

An element has an atomic number of 17 and a mass of 35. How many protons, neutrons, and electrons does the element have? What do these four elements have in common? They all have an incomplete valence electron shell.

What is the function associated with the indicated neural activity?

What is the function associated with the indicated neural activity? Ions are unequally distributed across the plasma membrane of all cells. This ion distribution creates an electrical potential difference across the membrane.

What is the difference between kinetic and potential energy mastering A and P?

What is the difference between kinetic and potential energy? Kinetic energy is energy in action, while potential energy is stored energy.

Which structure is indicated by the arrow quizlet?

The structure indicated by the arrow in the illustration below is the frontal lobe.

Which lobe of the brain is indicated by the arrow?

Diagram showing left side of the brain with the parietal lobe, coloured yellow and indicated with a red arrow. An important part of the visual brain is found at the back of the parietal lobes, close to where they meet the occipital lobes. These are called the posterior parietal lobes.

What do carbon and hydrogen have in common?

What do the four elements most abundant in life – carbon, oxygen, hydrogen and nitrogen – have in common? They all have the same number of valence electrons. They all have unpaired electrons in their valence shells. They are elements produced only in living cells.

What element is most carbon?

Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen.

Why can dehydration be such a life threatening event?

Hypovolemic shock: This occurs when a low blood volume causes the person’s blood pressure and amount of oxygen in the body to drop. This is one of the more serious conditions that can come from dehydration. If not treated, it can become life – threatening.

Are longer axons more likely to be myelinated?

No; they can be either myelinated or unmyelinated. Myelinated axons are ensheathed along their entire length. The axon caliber (diameter) in mammalian PNS ranges from 0.1 μm to 20 μm, with unmyelinated axons being less than 2 μm and myelinated axons being more than 1–2 μm in diameter.

Why is neuronal activity important?

Neuronal activity plays an essential role in shaping synaptic strength and connectivity at all stages of neuronal development and function. A neuron reacts to changes in synaptic transmission by modulating gene expression programs, which in turn regulate important synaptic factors.

Where do most action potentials originate?

Action potentials can originate not only at the axon hillock, but also in the axon initial segment, 30–40 μm from the soma and close to the first myelinated segment. In some neurons the action potential even originates at the first node of Ranvier, where sodium channels are highly concentrated (Figure 1).

How do you know if something is kinetic or potential energy?

The main difference between potential and kinetic energy is that one is the energy of what can be and one is the energy of what is. In other words, potential energy is stationary, with stored energy to be released; kinetic energy is energy in motion, actively using energy for movement.

What are the similarities between kinetic and potential energy?

One of the most important similarities between potential energy and kinetic energy is that they can both be converted into each other’s form of energy. When a force is applied to potential energy it converts to kinetic energy. This means that when an object such as a ball is still it has the potential to move.
