If the na+ voltage-gated channels in a muscle cell open, what will be the result?

Answers

If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.
If Na+ voltage-gated channels open, Na ions will enter the cell and make it less negative or more positive. The neuromuscular junction is a chemical synapse. ... This action potential is propagated along the sarcolemma of the muscle fiber, which triggers sliding of the myofilaments for muscle contraction.

written description of how carbon moves through the biosphere, atmosphere, hydrosphere, and geosphere.

Answers

Carbon is present in the biosphere and other systems of the planet and is an essential part of life. Carbon moves through these systems by feeding the heterotrophs of other organisms, through the consumption of dead organisms. When oxygen is present, there is aerobic respiration, which releases carbon dioxide into the surrounding air or water. It plays an important role in the structure, biochemistry, and nutrition of all living cells.

The noble gas present in relatively large concentrations in the atmosphere is

Answers

The noble gas present in relatively large connections in the atmosphere is ARGON
Final answer:

The noble gas present in relatively large concentrations in the atmosphere is Argon. It makes up about 0.93% of the Earth's atmosphere and is the most abundant among the noble gases.

Explanation:

The noble gas that is present in relatively large concentrations in the atmosphere is Argon (Ar). This is because Argon makes up about 0.93% of the Earth's atmosphere, making it the most abundant noble gas. The noble gases are typically unreactive due to their full electron shells and include Helium, Neon, Argon, Krypton, Xenon, and Radon. Of these, Argon is the most common in our atmosphere due to its stability and the fact that it is produced in significant quantities through the radioactive decay of Potassium-40.

An 83-year-old woman is placed at a small table in a dark corner of a trendy nightclub and is ignored by the staff. her shoddy treatment is probably due to her age, which is a(an) ______________ status.

Answers

This is an ascribed status. These are the characteristics and parts of one's being that are attained at birth or given to them later in life without their control. Age, sex, race, ethnicity: all of these characteristics are largely out of a person's control and are ascribed to them from the time they are born.

The elderly woman's poor treatment is due to her ascribed status of age, leading to ageism. Ageism involves discrimination and stereotyping that result in unequal treatment and can affect health, healthcare, and financial security for the elderly.

The 83-year-old woman's shoddy treatment at the nightclub can be attributed to her ascribed status, which is a position in society that one is given involuntarily, often based on characteristics such as race, ethnicity, gender, and age. In this instance, the woman's age is an ascribed status that has likely led to her experiencing ageism. Ageism involves stereotypes and discriminatory practices that result in unequal treatment of individuals because of their age. In many societies, including the United States, there are negative stereotypes about older adults being incompetent, physically weak, and unattractive.

Thus, the elderly, especially women and people of color, often face additional challenges related to health, healthcare, and financial security, which are compounded by a lifetime of inequalities. This not only affects their experiences in social settings like nightclubs but also has serious implications for their overall quality of life.

During _______________ the homologous chromosome pairs separate in a random fashion leading to genetic diversity among the offspring.

Answers

"During meiosis I the homologous chromosome pairs separate in a random fashion leading to genetic diversity among the offspring."

It is during meiosis I that segregation of the homologous chromosomes happens. In this phase, all the homologous chromosomes are aligned in the centre of the cell and then pulled apart, each homologous chromosome to an opposite pole of the cell. This allows genetic diversity because is guaranteed that from each of the parents, the offspring only gets one of the homologous pair of chromosomes.

Which structural feature of the cell membrane allows molecules such as oxygen and carbon dioxide to diffuse into and out of the cell? *

The cell membrane contains proteins molecules.
The cell membrane contains cholesterol molecules.
The cell membrane is made up of two layers of phospholipids.
The cell membrane is anchored to the cytoplasm by the cytoskeleton.

Answers

Final answer:

The two layers of phospholipids in the cell membrane allow molecules like oxygen and carbon dioxide to diffuse into and out of the cell.

Explanation:

The correct structural feature of the cell membrane that allows molecules such as oxygen and carbon dioxide to diffuse into and out of the cell is the two layers of phospholipids. The cell membrane is composed of a phospholipid bilayer which has a hydrophobic interior and hydrophilic exterior. This arrangement allows small, nonpolar molecules like oxygen and carbon dioxide to easily pass through the membrane by simple diffusion.

Answers


The function of evolution of organisms is to aid in the increased chance for life to thrive and survive. Earthquakes, volcanic eruptions and climate change are also natural occurrences and selective factors that force species to evolve and adapt to their environment. They contribute to organisms’ adaptability through cellular and organismic adaptation because these organisms want to survive.

C.

D.
repeating patterns of isotopes

Answers

I just did this quiz , the answer is A .

Answer: Option (A) is the correct answer.

Explanation:

Elements that belong to the same group show similar chemical properties.

This is because elements that lie in the same group have same number of valence electrons. Hence, they tend to show same type of reactivity which makes them exhibit similar chemical properties.

For example, all alkali metals are very reactive in nature as all of them contain 1 valence electron.

Therefore, in a group pattern of outer electrons is repeating.

Thus, we can conclude that a repeating pattern of outer electrons is the arrangement which is represented in the periodic table.

A lizard lives in a desert. which would be an adaptation for this lizard?

Answers

Hello Dpickard5164, a lizard lives in a desert, which would be an adaptation for this lizard, camouflage so they blend into their surroundings, body temperature, and preventing lethal extremes.

The adaptations in a lizard living in a desert include camouflage, heat tolerance, nocturnal behavior, burrowing, and specialized diet.

What are the adaptations?

A lizard living in a desert would likely have several adaptations to help it survive in the harsh environment. Some of these adaptations may include:

1. Camouflage: The lizard may have a color pattern that matches its surroundings, allowing it to blend in and avoid predators.

2. Heat tolerance: The lizard might have physiological adaptations that help it withstand high temperatures, such as a higher tolerance for dehydration or a more efficient cooling mechanism.

3. Nocturnal behavior: To avoid the extreme heat of the day, the lizard might be active primarily at night when temperatures are cooler.

4. Burrowing: The lizard may have adaptations for digging, allowing it to create burrows to escape the heat and provide shelter.

5. Specialized diet: The lizard might have a diet that is specifically suited to its environment, such as eating insects or plants that are more common in the desert.

These are just a few examples of adaptations that a desert lizard might possess to help it survive and thrive in its arid environment.
