Polarity of bonds and molecules is determined by the ______________ of the atoms involved.
Explanation:
Polarity is defined as the formation of opposite charges on the atoms of a compound due to the difference in their electronegativities.
For example, in a HCl molecule chlorine is more electronegative in nature as compared to the hydrogen atom.
Hence, chlorine will attract the valence electron of hydrogen atom more towards itself. Due to this a partial positive charge will develop on hydrogen atom and a partial negative charge will develop on the chlorine atom.
Thus, we can conclude that polarity of bonds and molecules is determined by the difference in electronegativity of the atoms involved.

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.

Which of these organelles is present in both prokaryotic cells and eukaryotic cells?
Ribosomes are organelles present in both prokaryotic and eukaryotic cells. They are essential for protein synthesis. Unlike other organelles, ribosomes can function without a membrane, making them universal across all cell types.
The correct answer to the question about which organelle is present in both prokaryotic cells and eukaryotic cells is the ribosome. Ribosomes are essential for protein synthesis and are found in both prokaryotic and eukaryotic cells. While eukaryotic cells contain membrane-bound organelles like the nucleus and mitochondria, prokaryotic cells do not. However, both types of cells share the presence of ribosomes for translating mRNA into proteins.
Here are the important points to remember:
Nucleus: Only in eukaryotesMitochondrion: Only in eukaryotesVacuole: Typically in plant and fungal cells, not in prokaryotesRibosomes: Present in both prokaryotes and eukaryotesRibosomes are not surrounded by a membrane and function as the site of protein synthesis, essentially translating genetic information into functional proteins. This makes them a universal and crucial component of all living cells, regardless of whether they are prokaryotic or eukaryotic.

A major oil spill has just happened in a near-shore environment. What prediction could be made as to why an oil spill in this area would be much more dangerous to marine life than one in the open ocean?
Answer:
An oil spill happening near the shore would be more dangerous because now not only is aquatic life in danger so are humans, in the sense of them swimming in the oil and possibly ingesting it. which would cause poisoning and could potentially lead to death.

The two processes that determine the world's current biodiversity are
Final answer:
Biodiversity is shaped by two key evolutionary processes: speciation, which creates new species, and extinction, which removes species. The balance and fluctuations between these processes determine the rise and fall of biodiversity levels over time.
Explanation:
The two evolutionary processes that determine the world's current biodiversity are speciation and extinction. These processes serve as the 'birth' and 'death' of species, contributing to the dynamic nature of biodiversity throughout geological time. When the rate of speciation exceeds that of extinction, biodiversity increases, and conversely, it decreases when extinction rates are higher. These fluctuations are evident from the fossil record and have led to dramatic changes in biodiversity over Earth's history.

The development of specialized tissues and organs in a multicellular organism's embryo occurs as a result of the differentiation process.
What is Embryo?
An unborn baby at an early stage of development in the uterus is called an embryo. It is responsible for the development of simple to complex structures in the body of multicellular organisms.
Differentiation is a process of the generation of specialized cell types and organs in multicellular organisms. During this process, a cell ceases to divide and develops specialized structural elements and distinct functional properties.
Therefore, the development of specialized tissues and organs in a multicellular organism's embryo occurs as a result of the differentiation process.

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.
What is a flatworm?Flatworms came under phylum platyhelminths.

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.

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'.
