Tissue culture, also known as micropropagation, is a biotechnological process in which plant cells are grown with growth hormones to produce genetically identical plants.
Explanation:The process described in the question is known as tissue culture or micropropagation. It is a technique used in biotechnology to produce a large number of genetically identical plants from a single plant cell or tissue. Plant cells are isolated and grown in a sterile environment with a special mixture of growth hormones, under controlled conditions. The hormones, typically auxins and cytokinins, stimulate the plant cells to divide and differentiate, eventually forming a whole plant. Each of these plants will have the exact genetic makeup of the original specimen, which makes this process especially useful in agriculture and horticulture for reproducing high-quality plants.

What is the cause of inflammation of the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli of the lungs?
Answer:
There is not just one type of respiratory infection, but several infections that can reach the respiratory tract, some lighter and some more severe. Some of the most common causes of respiratory infections include:
Common Cold or Flu: It is an infection caused by viruses, causing cough, runny nose, sneezing and nasal obstruction. In influenza, there is infection with influenza viruses, which cause more intense symptoms such as body pain and fever.Sinusitis: is the infection caused in the bones of the face and can cause headache, facial pain, nasal discharge, cough and fever, caused by viruses, bacteria or fungi;Pharyngitis: There is infection of the throat region, causing local inflammation, as well as runny nose and cough, most often caused by viruses;Tonsillitis: pharyngitis may be accompanied by tonsil infections, causing intense inflammation, being more intense when there is infection by bacteria, which can produce pus in the region;Bronchitis: is the inflammation of the bronchi, already considered a low respiratory infection, since it already reaches the lungs. It causes coughing and shortness of breath and may have both allergic and infectious causes from viruses or bacteria.Pneumonia: It is the infection of the lungs and pulmonary alveoli, which can cause intense secretion, cough, shortness of breath and fever. It is usually caused by bacteria, it can also be caused by viruses or fungi;Tuberculosis: This is a type of lung infection caused by the bacterium of Koch bacillus, which causes chronic, gradual inflammation with cough, fever, weight loss and weakness, which can become severe if treatment is not done promptly.These infections can be classified as acute when they appear suddenly and rapidly worsen, or as chronic when they have a long lasting, sluggish course and difficult to treat, which often happens in certain cases of sinusitis, bronchitis or tuberculosis. , for example.

He human eye is poorly suited to night vision, suffering impairments in __________.
The human eye is grief in damage of in-depth perception, color recognition, and peripheral vision. Judging speed and distance based on visual evidence is also more difficult in the dark. In addition, the darkness of night, and even the dimness of dusk and dawn.
Answer:
He human eye is poorly suited to night vision, suffering impairments in seeing the environment in low light situations.
Explanation:
In the eyes are the rods, the neurons responsible for the night vision. In total darkness, there is a need for at least 45 minutes to get the best vision, because the human eye is poorly adapted to night vision and is deficient in seeing in the dark. In the retina of the human eye there are two distinct regions, one responds by the central vision, the macula, and another peripheral vision.
Inside the macula, a region called fovea consists only of cones, which are neurons responsible for maximum vision. The cones do not work in low light conditions. However, around the fovea, there is a mixture of conese rods. This blend allows an intermediate view, which guarantees the ability to see in the penumbra.
identify the four principles of natural selection
The four principles of natural selection are variation, inheritance, high rate of population growth, and differential survival and reproduction. These principles explain the differences in traits among individuals within a species, the hereditary nature of some of these traits, overproduction of offspring, and the survival advantage of favorable traits.
Explanation:The four principles of natural selection are: Variation, Inheritance, High Rate of Population Growth, and Differential Survival and Reproduction.
The principle of Variation explains that within a population, individuals have diverse traits, these differences could be physical or behavioral. The principle of Inheritance explains that some of these traits are hereditary and can be passed on to the next generation.
The principle of a High Rate of Population Growth says that most species produce more offspring than can survive given the limited resources, and thus many offspring do not survive to reproductive age. The principle of Differential Survival and Reproduction suggests that those individuals with the most favorable traits are more likely to survive and reproduce, thereby passing on these traits to the next generation. This is often referred to as 'survival of the fittest'.

The binding of epinephrine to its receptor activates ________ which in turn activates ________. protein kinase a ; adenylyl cyclase protein kinase a ; g protein adenylyl cyclase ; g-protein g-protein ; protein kinase a g-protein ; adenylyl cyclase
The binding of epinephrine to its receptor activates g-protein which in turn activates adenylyl cyclase.
When epinephrine binds to its receptor, it triggers a cascade of events leading to the conversion of ATP to CAMP by adenylyl cyclase. This signaling pathway plays a crucial role in mediating cell-specific responses.
What effect does skipping breakfast have on daily food intake patterns?
Research indicates that skipping breakfast increases food portion intake for the rest of the day. This is due to increased hunger pangs. This result to overeating in the other meals of the day, by especially craving for foods with higher energy densities. Eating breakfast is usually advisable for person tying to lose weight or avoid obesity.
The answer is resulting into the effect of overeating in different meals of the day.
Explanation:It is all because of the hunger increased pangs that will be responsible for skipping of the food meals. This will be resulting into the overeating of the meals at the high energy based densities.

During the follicular phase, granulosa cells secrete ________, which stimulates secretion of ________.
During the follicular phase, granulosa cells secrete estrogen, which stimulates secretion of gonadotropin-releasing hormone (GnRH), which then increases production of luteinizing hormone (LH). The follicular phase is the phase of the menstrual cycle, during which follicles in the ovary mature and it ends with ovulation.
During the follicular phase, granulosa cells secrete estrogen which stimulates the secretion of gonadotropins such as FSH and LH.
During the follicular phase, granulosa cells secrete estrogen, which stimulates the secretion of gonadotropins by the anterior pituitary gland. Specifically, Follicle-stimulating hormone (FSH) stimulates the follicles leading to their growth and secretion of estrogens. Granulosa and theca cells, upon receiving Luteinizing hormone (LH), produce the sex steroid hormone estradiol. This increase in estrogen levels results in a negative feedback loop that regulates the secretion of GnRH, FSH, and LH to optimize the chances of one dominant follicle reaching maturation and ovulating an egg cell.

Two students are planning an experiment that will test how planaria (aquatic flatworms) respond to different environments. They will conduct two investigations—one that tests the worms’ responses to different water temperatures and one that tests the worms’ responses to different levels of acidity. Student 1 wants to buy two groups of flatworms and use a different group for each investigation. Student 2 thinks the same group of worms should be used for both investigations. Do you think either student’s method would give more accurate results? Why or why not? Explain your response.
Student 1’s methods would be more accurate, because the student would control more factors. Only one variable at a time (either temperature or acidity) would be tested on each group of worms. On the other hand, Student 2 is testing both factors on all the worms, which could make the results unclear.
Student 1 is taking different groups of worms, so his result will be more accurate, because the same group of worms may show the same or more related result.
