To believe that humans are rational is to believe that humans act on the basis of reason.
Why are human beings rational?Because it has intelligence that gives it the ability to communicate through a structured language based on speech, increasing its power to communicate, to issue judgments and to develop methodologies capable of increasing the quality of life.
Rationality is a characteristic that differentiates humans from animals, being this focus for social development, for the development of technology and science, which impacts our lives so much through engineering, medicine, mathematics, etc.
Therefore, acting based on reason is a characteristic of human beings, which is based on their intelligence and ability to think analytically to adapt and improve society.

During the t wave of the electrocardiogram, the ventricles are electrically ________ and functionally ________
During the t wave of the electrocardiogram, the ventricles are electrically repolarizing and functionally relaxing.
The T Wave shows ventricular repolarization when the ventricles relax after contracting and depolarizing. The ST segment shows the period between ventricular depolarization and repolarization, which is the space (a flat or slightly upcurved line) between the S wave and the T wave.
Although absent or downward sloping ST segments may suggest myocardial ischemia, a raised ST segment is the typical sign of myocardial infarctions. The U wave, which denotes the repolarization of the Purkinje fibres, comes after the T wave.
Because it is a relatively little wave in relation to the others, it does not usually appear on an ECG.

Why does strength and contrcation increase somwhat after a few stimulation/contraction events?
The muscle generates stress during the contraction phase, which is accompanied by the cycling of the cross bridges. During the relaxation phase, the muscle lengthens back to normal.
All of the muscle fibers connected to that motor neuron will contract as an action potential moves down the motor neuron. A muscle twitch is the contraction caused by a single action potential. A single muscle twitch consists of three parts. the contraction phase, the relaxation phase, and the latent period, often known as the lag phase. The action potential reaches the muscle, and the latent period is the brief (1-2 msec) interval before tension is seen in the muscle. This period of time is necessary for calcium to diffuse out of the SR, bind to troponin, transfer tropomyosin away from the active sites, build cross bridges, and pick up any slack in the system.learn more about contraction phase here: https://brainly.com/question/26765109

Read the scenario.
An ecologist is studying the ecosystems on a mountain slope
following a volcanic eruption. In the first year, the ecologist
observes that most of the slope is covered in ash and debris
and very few trees and shrubs survived. The ecologist also
observes no wildlife in the area. The ecologist wonders if the
ecosystem can recover.
The ecologist reads records of primary succession following
other volcanic eruptions and learns that certain organisms tend
to colonize the land first. In the following years, the ecologist
observes a few lichens growing on bare rocks and then a few
hardy grasses. Ten years after the eruption, the ecologist
surveys the landscape and finds small wildflowers, grasses, and
insects.
Which question most closely relates to the ecologist's
observations and collected data?
A. How many years will it take for the mountainside
ecosystem to return to its original state?
B. What reproductive strategies do plants use to grow
following a volcanic eruption?
C. Do the plants on the mountainside have a disease?

What differences did you observe in the structure of an artery versus the structure of a vein?
Arteries Larger, more muscular and more elastic, carry oxygenated blood from the heart, with the exception of the pulmonary artery. The blood has more pressure from the heart. Veins Under less pressure, so valves are needed. They are less strong than arteries and appear more floppy.
Arteries have thick, elastic, muscular walls whereas veins have thin walls with few elastic fibers. Arteries need these properties to give them the strength and elasticity needed to cope with the high pressure surges of oxygenated blood coming from the heart. Veins carry blood back to your heart from the rest of your body. The pressure of the blood returning to the heart is very low, so the walls of veins are much thinner than arteries.

Why are amphibians known as the ""planet’s greatest survivors""? How have they evolved over time?
Amphibians are referred to as the "planet's greatest survivors" because they have repeatedly avoided extinction over the course of 400 million years.

Over the years, the amphibians have had to adapt to various surroundings. Small animals called amphibians require water or a moist environment to exist. This group of species includes newts, salamanders, toads, and frogs. All have extremely thin skin that allows them to breathe and absorb water. Additionally, amphibians have unique skin glands that create functional proteins.
According to fossil evidence, amphibians descended from lobe-finned lungfish about 365 million years ago. They were very successful since they were the first terrestrial vertebrates.

The odds of finding the energy concentrated on just a few molecules in a macroscopically-measurable sample are very less likely.
If energy was only concentrated onto one molecule, the law of entropy is not followed because the system becomes organized into that one molecule only and the other molecules do not have energy. Due to the property of entropy, the energy will more likely be spread among all molecules rather than just one molecule.
