¿ Que condiciones del ambiente influyen en el comportamiento de la mariposa
monarca?

Answers

Answer 1

Answer:

Durante el invierno las mariposas monarca migran hacia el sur en busca de temperaturas más cálidas, y luego en primavera migran nuevamente hacia latitudes mayores  

Explanation:

La mariposa monarca (Danaus plexippus) es un insecto lepidóptero que habita América del Norte, la cual es conocida por llevar a cabo una de las migraciones más extraordinarias observadas en el reino animal. La subespecies de mariposas monarca D. plexippus plexippus es popularmente conocida porque sus poblaciones realizan una migración masiva hacia el sur durante los meses de agosto a octubre (es decir, antes del comienzo del invierno en el hemisferio norte) y, posteriormente, estas poblaciones migran nuevamente hacia el norte en primavera. Recientes estudios han determinado cómo la temperatura induce un cambio de dirección de vuelo (es decir, el patrón de migración) de estas mariposas, lo cual demuestra que los efectos del cambio climático reprentan un grave peligro no sólo para la biodiversidad de Danaus plexippus, sino también para las especies vegetales autóctonas que se benefician de este polinizador natural y, en última instancia también, para toda la cadena trófica que abarca su radio de migración. Es por esta razón que el aumento en las temperaturas medias causado por el calentamiento global ha causado una gran alarma en la comunidad científica sobre sus efectos sobre esta especie.

Genetic abnormalities result in a cluster of distinct characteristics that tend to occur together respective to a given:

Answers

Genetic abnormalities result in a cluster of distinct characteristics that tend to occur together respective to a given individual's genetic makeup. Genetic abnormalities are responsible for a wide range of physical and cognitive disabilities.

Genetic abnormalities result from changes in the DNA sequence of an individual that can affect one gene or multiple genes.There are different types of genetic abnormalities, such as chromosomal abnormalities, single gene disorders, and multifactorial disorders. Chromosomal abnormalities occur when the number or structure of chromosomes is changed.

Down syndrome is an example of a chromosomal abnormality.Single gene disorders result from changes or mutations in a single gene. Cystic fibrosis, sickle cell anemia, and Huntington's disease are examples of single gene disorders. Multifactorial disorders occur when a combination of genetic and environmental factors contribute to the development of a disorder. Heart disease, diabetes, and some types of cancer are examples of multifactorial disorders.

Some genetic abnormalities are inherited, while others occur spontaneously due to genetic mutations. Genetic abnormalities can affect any part of the body and result in a wide range of symptoms and disabilities. Treatment for genetic abnormalities is often focused on managing symptoms and improving quality of life for affected individuals. Genetic counseling and testing can help individuals and families understand their risk for genetic abnormalities and make informed decisions about family planning.

In conclusion, genetic abnormalities result in a cluster of distinct characteristics that tend to occur together respective to a given individual's genetic makeup. Genetic abnormalities are responsible for a wide range of physical and cognitive disabilities.

What are Bacterial cells?

Bacteria, singular bacterium, any of a group of microscopic single-celled organisms that are abundant on Earth and can be found in nearly every environment, from human digestive tracts to deep-sea vents.

Bacteria are classified as prokaryotes, which are unicellular life forms. They lack a membrane-bound nucleus and other internal components. Prokaryotes have dominated life on Earth for at least three-quarters of its existence and have adapted to nearly all of the planet's biological niches. They exhibit incredibly diverse metabolic capacities as a whole and can utilise practically any organic chemical as well as some inorganic compounds as food. While certain bacteria can infect people, animals, or plants with diseases, the majority of them are benign ecological agents 

What is flagella in bacterial cell?

A microbe may have a single flagellum or several. For instance, the gram-negative bacterium Helicobacter pylori uses its many flagella to break through the mucous membrane and reach the stomach epithelium, where it may lead to the formation of a gastric ulcer. The flagellum of some bacteria can also serve as a sensory organelle, sensitive to moisture outside the cell.

Consider a diploid organism with a haploid complement of 4 chromosomes in its gametes. At meiotic prophase I, how many total chromosomes copies will be present in a cell?

Answers

In a diploid organism with a haploid complement of 4 chromosomes in its gametes, meiotic prophase I will result in a total of 8 chromosome copies in a cell. This is because during meiosis, the cells undergo two rounds of cell division, resulting in four haploid cells with half the number of chromosomes as the parent cell.

During meiotic prophase, I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. This results in the formation of tetrads, which are groups of four chromatids. Each chromatid contains a copy of the same chromosome, so a tetrad contains two copies of each chromosome.
Therefore, at the end of meiotic prophase I, each cell will contain four tetrads, which is a total of eight chromosome copies. These chromosome copies will then separate during the subsequent stages of meiosis, resulting in the formation of four haploid cells, each with a unique combination of genetic material.
Overall, meiosis is a crucial process for generating genetic diversity and ensuring the production of viable gametes in sexually reproducing organisms.

Explanation:

a field containing soil that is 60 percent clay can hold a tremendous amount of nutrients but often has poor crop growth. what is the most likely explanation for this phenomenon? excessive concentrations of nutrients in soil can become toxic to many types of plants. clay can hold heavy metals that are toxic to plants. plant roots have difficulty penetrating a soil that is 60 percent clay. the base saturation of clay soil is too high for most plants.

Answers

The physical characteristics of soil can be broken down into twelve categories. Each of these physical characteristics of soil is important to agriculture and improves plant health in general.

One of the heaviest soils is said to be clay. Due to the capillary action between the clay particles, the soil can keep a lot of nutrients and water while draining more slowly. Clay soil has the tiniest particles of any type of soil for plant health.

Clay soil can be recognized rather easily. It may be rolled, smeared easily, and smoothed into a glossy finish. It is sticky when wet. However, clay soil has a propensity to become extremely hard as it dries, which leads to the clay cracking as it dries.

an abnormal condition of bone death (due to lack of blood supply) is

Answers

The abnormal condition of bone death due to lack of blood supply is called avascular necrosis.

Avascular necrosis is a condition characterized by the death of bone tissue due to a lack of blood supply. It can occur in any bone, but is most commonly seen in the hip joint. Without an adequate blood supply, bone tissue begins to die and can eventually lead to bone collapse and joint damage.

Avascular necrosis may be caused by a number of factors, including injury, prolonged use of corticosteroid medications, excessive alcohol consumption, and certain medical conditions like sickle cell anemia. Treatment options depend on the severity of the condition and may include medication, physical therapy, and surgery, such as joint replacement or bone grafting.

T/F In the human heart, the muscular structure of the ventricles enables them to pump blood a greater distance than atria can

Answers

True. In the human heart, the muscular structure of the ventricles enables them to pump blood a greater distance than the atria can.

True. In the human heart, the muscular structure of the ventricles enables them to pump blood a greater distance than the atria can. The atria are smaller and have less muscular walls compared to the ventricles that are larger and have more muscular walls. The left ventricle is responsible for pumping oxygenated blood to the rest of the body, while the right ventricle pumps deoxygenated blood to the lungs for oxygenation. The ventricles are chambers that pump blood through the circulatory system. They act as pumps and distribute blood throughout the body. The ventricles, unlike the atria, must have thicker, more muscular walls to produce the necessary force for blood to circulate throughout the body. In summary, the muscular structure of the ventricles in the human heart enables them to pump blood a greater distance than the atria can. The ventricles have thicker, more muscular walls, which helps produce the necessary force for blood to circulate throughout the body.

The limitations of using fossil in evolution theory are that fossils are rare and only show changes in bones of animals. In many environments the preservation of fossils is hard creating gaps in fossil records that can make identifying change very hard. And when changes present themselves they can be in many forms, such as changing in the soft tissue, coverage and thickness of hair, and changes in organs, all of which can not be preserved by fossilization.

The _____ is used to monitor the centering of the process.
Select one:
a .np-chart
b.-chart
c. R-chart
d. p-chart

Answers

The _R-chart_ is used to monitor the centering of the process.The correct answer is c. R-chart.

The R-chart, also known as the Range chart, is used to monitor the centering of the process. It is a statistical control chart that tracks the variability or dispersion within a process by measuring the range between the maximum and minimum values of a sample. The R-chart is commonly used in conjunction with the X-bar chart (also known as the process mean chart) to monitor process performance. While the X-bar chart focuses on the central tendency or average of the process, the R-chart helps assess the spread or variability of the process.

By plotting the ranges of multiple samples on the R-chart, one can determine if the process is exhibiting consistent variation or if there are shifts or changes in the dispersion. If the ranges remain within control limits, it indicates that the process is in statistical control and the centering is stable. However, if there are points that fall outside the control limits or a systematic pattern emerges, it suggests that the process variation has changed, and further investigation or corrective actions may be necessary. Overall, the R-chart is a valuable tool for monitoring the centering of a process by assessing the variability or dispersion within the process over time.

Decreased levels of bile salts in the bile would interfere with:
a. protein digestion.
b. fat digestion.
c. digestion of disaccharides.
d. digestion of complex carbohydrates.
e. digestion of vitamins.

Answers

Bile salts are a critical component of bile, which is produced by the liver and stored in the gallbladder. The correct answer is B. Fat digestion.

When food containing fat enters the small intestine, the gallbladder releases bile into the duodenum. Bile salts within the bile help to break down the large fat droplets into smaller droplets, increasing their surface area and allowing pancreatic lipase to more effectively break them down into fatty acids and glycerol.

If there are decreased levels of bile salts in the bile, it would interfere with fat digestion, as the bile would not be as effective at emulsifying the fats. This could lead to malabsorption of fats, which can cause a variety of symptoms including diarrhea, bloating, and weight loss. Additionally, decreased bile salt levels could also affect the absorption of fat-soluble vitamins, such as vitamins A, D, E, and K, which are necessary for a range of functions in the body.

Decreased bile salt levels would not have a significant impact on protein digestion, digestion of disaccharides, or digestion of complex carbohydrates, as these processes do not rely on bile salts for their effectiveness. However, the role of bile salts in fat digestion is critical, and any decrease in their levels could have significant consequences for overall digestive health.

The person did a lot of work because s/he pushed with a high force


No work was done because the boulder was not displaced

Answers

Answer:

No work was done because the boulder was not displaced.

Explanation:

Even if a person is pushing with a force of 50N and for 10 min, zero work is done and there's no acceleration. Zero work means when the force or displacement on the object is equal to 0 J, and since the boulder never moved it would be 0 J.  If the person was pushing with 50 N or even higher and the the object didn't budge, the velocity hasn't changed from rest and that would mean no acceleration occurred.
