Answer:
Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds. From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

What happens when an action potential is produced with a signal that is stronger than threshold?
A)
weaker action potential generated
B)
no action potential generated
C)
action potential has same strength as threshold
D)
stronger action potential generated
Answer:
C) action potential has same strength as threshold
Explanation:
What happens when an action potential is produced with a signal that is stronger than threshold action potential has same strength as threshold
When an action potential is produced with a signal that is stronger than the threshold, the resulting action potential is typically stronger or more intense compared to a standard action potential. The answer is D) Stronger action potential generated.
The threshold is the minimum level of depolarization required to initiate an action potential in a neuron. If the signal surpasses the threshold, it means that the depolarization is greater than what is necessary to trigger the action potential.
When a stronger signal is received by the neuron, it results in a larger influx of ions (such as sodium) into the neuron, leading to a more pronounced depolarization of the cell membrane.
As a result, the action potential generated will have a higher amplitude or voltage compared to a regular action potential. Therefore, the answer is D) Stronger action potential generated.

which antioxidant plays an important role in cell differentiation, the process by which stem cells mature into highly specialized cells?
Vitamin A is regarded as the antioxidant that plays an important role in cell
differentiation.
Cell differentiation is the process by which cells become specialized by
changing from one form to another to achieve a common structure and
function.
Vitamin A has a strong metabolite known as retinoic acid which is involved
in this process which supports it and also helps to eliminate the free radicals
which may be present.

The work of such researchers as Broca, Fritsch, Hitzig, and Ferrier demonstrated localized brain function, which was somewhat similar to the predictions made by ________.
The work of Broca, Fritsch, Hitzig, and Ferrier demonstrated localized brain function, which was similar to predictions made by phrenologists. Phrenology is a pseudoscience.
Phrenology is a pseudoscience aimed at measuring bumps on the skull to predict personality traits.
Eduard Hitzig and Gustav Fritsch demonstrated that electrical stimulation of specific areas of the cerebral cortex could trigger movement.
Broca's area is an area located in the frontal part of the left brain hemisphere discovered by Paul Broca, who observed how this area has a fundamental function for the generation of speech in humans.
Finally, David Ferrier was a neurologist who discovered a series of motor fields within the cerebral cortex of monkeys.

As a result of higher osmotic gradient outside, ____________ moves out of the thin descending limb of Loop of Henle
Answer:
is it water?
Explanation:
As a result of higher osmotic gradient outside, water moves out of the thin descending limb of Loop of Henle.
What is osmotic potential?Osmotic potential is a component of water potential whose magnitude depends on the amount of solutes present in the solution, with osmotic pressure defined as the pressure necessary to prevent osmosis from occurring.
The loop of Henle (or nephr), in anatomy, is the segment of the nephron that comes just after the proximal convoluted tubule, being a U-shaped tubular structure, with a thick and a thin portion. That can be done with the osmotic potential.

A running back is running down the field and two people on the opposing team run towards him. One person is running east with a force of 250 N. The other person is running west with 250 N of force . They all collide at the same time. Show the forces affecting the running back.
Are the forces balanced or unbalanced?
Net force = ?
Given our understanding of the laws of physics, we can confirm that the Net force affecting the running back (ignoring gravity and its complementary force) is that of 500N and balanced.
In physics, we can say that the net forces being applied to an object are balanced when the forces are
Equal in sizeApplied in opposite directionsApplied at the same time.The question states that the running back collides with two members of the opposing team at the same time. This, coupled with the fact that the opposing team members are described to arrive on exactly opposite sides, we can say that the forces being applied to the running back are indeed balanced.
Furthermore, since the forces are 250N in size each, we can confirm that the net force applied to the running back is 500N. To this, we would normally add the force of gravity, however, in order to do this, we would need the weight of the running back, that is, data that is not provided.

Given the number of blood vessels in the retina, why do you suppose that you are not able to see them normally
Answer:
You can't see the blood vessels themselves because vision depends on a process that makes it impossible to see things that are stationary with respect to the retina. Light receptors in the retina respond only to changes in light reaching them, not to a steady image.

Answer:
Many species of termites need to find areas of vegetation with plenty of moisture to survive. To get around their lack of vision, the pests have antennae covered with moisture-sensing receptors.They also have eyes but their wings do not develop further. These develop into the neotenics (see below), which are one of the reproductive types and have the ability to produce eggs in the colony in certain situations
