During a muscle contraction, the muscle cell membrane becomes temporarily permeable to
a. acetylcholine.
b. sodium
ОООО
с. АТР.
d. calcium.
During muscle contraction, the muscle cell membrane becomes temporarily permeable to sodium (Option b is correct).
Muscle cells are excitable, which means that these cells change from a resting state to an excited state in response to stimuli.At resting (non-signaling) state, Na+ ions are found at a higher concentration outside of the muscle cell than inside the cell, whereas potassium (K2+) ions are found at a higher concentration inside the cell than out the cell.When a nerve transmits an excitable signal that a muscle cell, Na+ flows into the muscle cell, and simultaneously potassium (K2+) ions out of the cell.The influx of Na+ ions is caused by the opening of voltage-gated sodium (Nav) channels found in the membrane (sarcolemma) of muscle cells.In conclusion, during muscle contraction, the muscle cell membrane becomes permeable to sodium ions (Option b is correct).

Cree usted que las diferencias anatómicas entre los individuos de la humanidad surgieron como respuestas a acondicionamientos ambientales
Answer:
no, la selección natural opera sobre los fenotipos seleccionando aquellos que mejor se adaptan a su medio ambiente. En consecuencia, el medio ambiente actúa como agente selectivo pero no es el disparador de los cambios fenotípicos/anatómicos
Explanation:
Jean-Baptiste de Lamarck fue un naturalista francés el cual propuso que los individuos se adaptaban para sobrevivir a su ambiente, y que estos cambios fenotípicos/anatómicos eran transmitidos a la progenie. Por otra parte, Darwin propuso la teoría de la evolución por selección natural la cual establece que aquellos individuos mejor adaptados a su ambiente tiene más chance de sobrevivir y reproducirse, y con lo cual también tienen más chances de trasmitir sus rasgos anatómicos/fenotípicos a la siguiente generación. Hoy en día, la teoría de la evolución de Darwin es ampliamente aceptada por la comunidad científica y permite explicar la variación existente entre individuos. De este modo, de acuerdo a la pregunta planteada, las diferencias anatómicas/fenotípicas entre los individuos de la humanidad no surgieron como respuesta al acondicionamiento ambiental: el ambiente funciona como agente selectivo, seleccionado aquellos individuos mejor adaptados a sobrevivir en cada ambiente en particular.

On May 18,1980, Mount St. Helens in the state of Washington erupted with the force of a hydrogen bomb. The volcano had been dormant for over 120 years, but now 57 people were dead; forests and lakes were totally destroyed, including nearby Spirit Lake, which became a mud hole. The blast leveled trees in areas over 10 miles from the crater and ash deposits suffocated life on the mountain. However, within weeks, mammals that had taken shelter underground started to appear in the area, and now, over thirty years later, many areas of the mountain are colonized with a large variety of plant and animal life. How does an area move from a sterile, barren wilderness to one full of life
Answer:
The correct answer is - Ecological Succession.
Explanation:
Ecological succession is a change in the species or biodiversity over time by the increase in the vegetation or growth of the community. This takes place after a natural disaster or any event that causes nudation or complete removal of species or comunities from an area such as volcanic eruption.
It starts with nudation then invaded with primary successors and then ecological conditions lead to invading more species and the third stage would be competition and interaction between a component of the species and vegetation then stable.

How is composting solid waste similar to and different from burying it in a landfill?
Answer:
Basically, this means that because municipal solid waste that is buried in a landfill does not receive oxygen, it will produce methane. A compost pile, on the other hand, undergoes aerobic decomposition. ... But, if a compost pile is being taken care of properly, it will produce far less methane than a landfill.

Describe what happened to the colored water and the pieces of paper after the holes were punched in the material covering the beaker
Answer:
The paper spreads over the surface of water and the colored water sunk to the bottom.
Explanation:
The paper hole punches were spread over the surface of the water in the large beaker due to lower density of paper as compared to water whereas the colored water had sunk to the bottom. Convection currents is the driving force that caused the pieces of paper to move over the water's surface. At the surface, the water cools and becomes more denser so the coloring sank toward the bottom of the beaker creating convection currents that will leads to the presence of paper on the surface of water.

Many desert mammals have developed a nocturnal lifestyle. This means that during the day they sleep underground in their burrows, and they come out to eat and play at night. What is a good reason for a desert fox to show this pattern of behavior?
Answer:
A good reason why a desert fox shows this pattern of behavior is to protect themselves from cold conditions since at nighttime, it gets very cold in the desert!
Explanation:
Nocturnal is a type of animal behaviour shown when the animals are active at night time and inactive at daytime. Desert fox shows this behaviour so that it can avoid the hot daytime of the desert.
What is nocturnal behaviour?Nocturnal lifestyle is the behaviour adopted by animals that are active at night time and are inactive during the daytime. During the daytime, they rest in the cool burrows, holes and underground canals to prevent the loss of water and to protect themselves from the extremely hot environment.
The desert animals like desert foxes have adapted the nocturnal lifestyle to avoid the extreme heat during the daytime and sleep in their underground burrows. Instead, they come out during the night when it is cool in deserts to eat and play.
Nocturnal lifestyle is shown by the diurnal animals that rest and sleeps in the burrows, holes and cool places during the hot time of the day.
Therefore, the desert fox shows a nocturnal lifestyle.

5. Radioisotopes
Radioisotopes are isotopes that are radioactive—they spontaneously emit energy (or radiation) when their nucleus breaks down. The term for this process is radioactive decay. When the process involves a change in the number of protons in the nucleus, the atom can change into another element. In one type of radioactive decay, a neutron in the nucleus splits into a proton and an electron. This split decreases the number of neutrons by one and increases the number of protons by one, but since protons and neutrons have approximately the same mass, the mass number stays the same. Since the number of protons changes, the atom becomes a new element.
Carbon-14 has 8 neutrons and 6 protons. When this radioisotope undergoes the radioactive decay process discussed above, it becomes nitrogen-14.
The number of protons in nitrogen-14 is?
Answer:
7
Explanation:
The number of proton becomes 7 in nitrogen- 14 because there is one proton increase in the nucleus as a result of radioactive decay. There are 6 number of protons and 8 number of neutron in the nucleus of carbon-14 isotope. when the radioactive decay occurs, there is decrease occur in neutron number by removing one neutron and number of proton increases in the nucleus due to addition of one proton so that's we can say that the number of proton in nitrogen-14 is 7.

The results of investigators who endeavor to show that the permeability increases in light only for some substances, while it may decrease in light for other substances, and that the permeability of protoplasm of some plants increases in the dark while it is not changed by the change of illumination in other cases, are incorrect since the methods used by these investigators to determine the permeability were inexact or faulty
