Fill in the blank question. The initial effect of a stimulus on a sensory receptor is a small, local change in membrane potential called a(n)

Answers

Answer 1

Answer:

The initial effect of a stimulus on a sensory receptor is a small, local change in membrane potential called a(n) receptor potential.

Explanation:

The process used by sensory receptors to transform the physical energy of the sensory stimulus into action potentials, the fundamental unit of information in the nervous system, is called sensory transduction. The entrance of positive charges towards the interior (mainly Na +), will cause a depolarization; while if there is an exit of positive charges from the interior (mainly K +) then hyperpolarization will occur. This change in membrane potential is called the receptor potential. A receptor potential is then a local potential that can sometimes represent the only response that results from the transduction process, for example in the taste sensory cell.

What are seasons?

A season exists the year that stands determined by particular climate conditions. The four seasonsspring, summer, fall, and winter—follow one another regularly. Each includes its light, temperature, and weather designs that repeat yearly.

Summer exists the hottest of the four temperate seasons, happening after spring and before autumn. At or centered on the summer solstice, the earlier sunrise and latest sunset happen, daylight hours exist longest and dark hours exist shortest, with day length falling as the season progresses after the solstice.

Winter, the coldest season of the year, between autumn and spring; the name arrives from an old Germanic word that represents “time of water” and guides to the rain and snow of winter in middle and increased latitudes.

Hence, Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.

Describe how pollution can cause acid rain, and how acid rain affects the ecosystems of surrounding areas?

Answers

Pollution specifically air pollution can cause acid. Gases such as sulphur (IV) oxide and Nitrogen (IV) oxide when they are released into the atmosphere and comes into contact with precipitation, that is rain water causes acid rain. Sulphurous acid and Nitric acid is formed thus the rain falls in acidic form.

Acid rain when it falls on the leaves of the flora (plants) causes removal of the green colouring matter (chlorophyll) thus making plants to be deficient of food. Food in plants is made my the process of photosynthesis, removal of chlorophyll in plants kills them due to lack of food.

Also when acid rain finds it's way into the water bodies through surface runoff, aquatic animals such as fishes die due to lack of favourable environment and oxygen deficiency in water. Acidity in the soil also kills important decomposers therefore soil aeration is altered.

acid rain can affect the surrounding areas by ruining its ecosystem

Why has the number of people in the world increased if the human population growth rate has decreased?

Answers

Answer:

Life expectancy has steadily risen.

People live longer lives.

To understand the reasons why the number of people in the world has increased and the population growth rate has decreased, it is necessary to understand how the world's demographic growth rate is calculated.

The calculation is made from the balance between the total number of people alive and the total number of deaths that occurred in a period of time.

Therefore, we can understand that the population growth rate has decreased due to several relevant factors, such as:

Increased life expectancy.The decrease in infant mortality.Rising fertility rates.Urbanization.Economic development.

These are some of the reasons that help us understand why population numbers increase and population growth rate decreases.

Economic development, new technologies and a better quality of life for the population are directly related to the decrease in the population growth rate.

In a population of wild bees, a mutation resulted in slightly larger wingspan in some of the bees. This larger wingspan made the bees more efficient in their flights to flowers to collect nectar. Thus, these bees became more successful. This trait was passed on to offspring, and eventually the larger wingspan variety of bee replaced their smaller-winged relatives completely. It could be said that ____ favored the bee with the larger wingspan, and so the ____ evolved

Answers

Answer:

The correct answer is - natural selection, population.

Explanation:

In this case, the wild bees population experienced a mutation which helps in become more eeficient to fight for nector. This bees population is more sucessful to other that didnt recieved mutation and this mutation as it is adavtageous.

You treat a sample of DNA with DNase and run the digested fragments out on an electrophoretic gel. You found mostly long fragments. What can you conclude about this sample of DNA

Answers

Answer:

the sample contains mostly heterochromatin  

Explanation:

Heterochromatin refers to a highly condensed state of DNA, whereas euchromatin is lightly packed. It is for that reason that heterochromatin is associated with a transcriptionally inactive state, whereas euchromatin regions are active for transcription. Heterochromatin regions resist DNases because these enzymes don't cut DNA randomly, but they show sequence preference. In consequence, highly repetitive DNA heterochromatin regions (e.g., centromeres, telomeres, etc) may exhibit resistance to DNA cleavage.

A common genetic mutation that lowers levels of the enzyme cathepsin C severely reduces a person’s ability to ward off periodontitis, or gum disease. The enzyme triggers immunological reactions that destroy diseased cells and eliminate infections
in the mouth. But researchers are developing ways to restore the enzyme to normal levels. Once that happens, we will be able to eliminate periodontitis.
Which one of the following is an assumption on which the argument depends?
(A) Restoring cathepsin C to normal levels is the only way to eliminate periodontitis.
(B) Genetic mutation is the only cause of lowered levels of cathepsin C.
(C) Researchers will soon succeed in finding means of restoring cathepsin C to normal levels.
(D) Persons who do not have the genetic mutation that lowers levels of cathepsin C do not get gum disease.
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.

Answers

Answer:

(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.

Explanation:

Considering the fact that there may be some other causes of periodontitis aside from the lowered levels of the enzyme.

Therefore, should there be some other causes of periodontitis, hence, it can be concluded the process of restoring the enzyme to normal levels might not be sufficient for eliminating periodontitis.

Hence, the author's argument is solely based on this assumption, and option. Hence, option (E) is the correct answer.

Which type of cell adhesion is useful for anchoring cells together and defending against shear forces on tissues

Answers

Answer:

Desmosomes

Explanation:

Desmosomes are cellular structures that adhere to neighboring cells. Its function is to hold the epithelial cells together, associating the intermediate filament cytoskeletons of neighboring cells, thus forming a transcellular network with high resistance to mechanical traction. It thus allows the cells to maintain their shape and the epithelial sheet to exist in a stable form. Inside cells act as anchoring sites for intermediate rope-shaped filaments, which form a structural network in the cytoplasm providing a certain rigidity. Through these junctions the intermediate filaments of the adjacent cells are indirectly connected forming a continuous network that extends throughout the tissue.
