How did diffusion of the perfume change with an increase of concentration

Answers

Answer:

Explanation:

Diffusion is trigger by concentration differences.

When perfume is sprayed in the room, the molecules of the perform come in contact with the air molecules and tend to mix well with air molecules, this molecules then spread and move from area of lower concentration to an area of higher concentration. Because the molecules are in constant motion, they move to area where there is high concentration.

5. What is symbolic about the Dragon’s Cup and why was it added to the movie?

Answers

The dragon's cup was an alliance between Beowulf and Grendel's mom, it was a symbol of their truce. It fits the movie and kind of symbolizes the fight between the dragon and Beowulf.

Beowulf and Grendel's mother formed an alliance, and the dragon's cup served as a sign of their understanding. It is appropriate for the film, and perhaps alludes to Beowulf and the dragon's conflict.

What  is symbolic about the Dragon’s Cup?

The dragon's hoard of treasure eloquently symbolizes both, the flimsiness of human desires and the changeability of time. The wealth in the dragon's tomb is plentiful, but no one can use it.

Gardner uses the dragon as a symbol for life's sorrow—the kind of misery that might result in the gloomy beliefs (and disgusting social behaviors) he eventually shares with Grendel.

Beowulf grabs a knife from his belt and stabs the dragon's flank desperately. The fatal strike causes the writhing serpent to wither.

But as soon as Beowulf achieves victory, the cut on his neck starts to enlarge and burn. He understands that the venom from the dragon bite is killing him.

Therefore, flimsiness of human desires and the changeability of time symbolic about the Dragon’s Cup.

Number 8. was colorblind just like his father: Where did the son at 8 get his allele for colorblindness?

Answers

Answer:

son 8 inherited it from her.

Explanation:

Given that Son 8's mother is a carrier of the blindness allele

Assuming that the father is colorblind due to a genetic mutation, there are a few possible scenarios for how the son inherited the allele for colorblindness.

What is genetic inheritance?

Genetic inheritance is the study of how certain inherited traits are passed down from generation to generation.

Assuming the father is colorblind due to a genetic mutation, there are a few possibilities for how the son inherited the colorblind allele:

His father's colorblindness allele was passed down to his son. The son in this case inherited the mutation from his father.The mother carries the colorblindness allele, which she passed on to her son. In this case, the son inherited the mutation from his mother, who is not colorblind but carries the gene.The colorblindness mutation is present in both the mother and father, and the son received one copy from each parent. This is a less likely scenario, but it is possible if both parents carry the gene.

Thus, in any of these scenarios, the son inherited the allele for colorblindness from one or both of his parents.

During glycolysis, the molecule glucose is broken down into pyruvate. What type of reaction is this?

Answers

Explanation:

Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.

Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.

The overall equation for this pathway is:

1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O

Explain the difference between sex hormones and glandular stimulating hormones

Answers

Answer:

Sex hormones are those hormones that within the endocrine system of the human being, are considered more directly involved in human sexuality, particularly in the processes of copulation and reproduction.On the other hand, glandular stimulating hormones are those that act on hormonal production in another endocrine gland, that is, they are stimulants, since they stimulate the corresponding glands.

Explanation:

Sex hormones are chemical substances secreted by the sex endocrine glands (the testes and ovaries) and subsequently released into the bloodstream, to be transported to the organs on which they exert their action (increasing or decreasing their activity).The production of hormones is regulated in many cases by a negative feedback system, which causes an excess of a hormone to be followed by a decrease in its production. The glandular stimulating hormones are transported to the blood to stimulate the corresponding glands (thyroid, adrenal cortex, and gonads) and these will be the ones that secrete various types of hormones (thyroxine, corticosteroids and sex hormones, respectively), which in addition to acting in the body, they feed back into the pituitary and hypothalamus to inhibit their activity and balance the respective secretions of these two organs and the target gland. For example, follicle-stimulating hormone encourages sperm production in men and stimulates the ovaries to release eggs in women. Luteinizing hormone and follicle stimulator work together to allow normal function of the ovaries or testicles.

I think the answer is b.

Goblet cells' main job is to secrete mucin and produce a layer of protective mucus. Goblet cells may possibly have a role in the regulation of the immune system.Thus, option B is correct.

What epithelium is associated with goblet cells?

Goblet cells' primary function is to secrete mucus in order to safeguard the mucous membranes that surround them. This is done by goblet cells secreting mucins, which are big glycoproteins made primarily of carbohydrates.

Goblet cells exhibit a distinctively polarized morphology regardless of fixation. Along with organelles like the Golgi, endoplasmic reticulum, and mitochondria, their nucleus is located at the base of the cell.

Mucus-filled secretory granules that are membrane-bound fill the remaining space in the cell.

Therefore, Most of the major airways are lined with pseudostrategized ciliated columnar epithelium that contains goblet cells. This tracheal pseudostratified epithelium is an illustration.

When evaluating the viruses that had infected these hosts the previous year, she identifies a cross-species transfer from pigs to ducks in the year 2022. What information supports the hypothesis that cross-species transfer leads to more severe disease in the new host

Answers

Answer:

pigs suffered severe influenza in the year 2022  

Explanation:

Influenza, commonly known as flu, is a viral infectious disease caused by different types of influenza viruses. Some of the most common symptoms of this disease include, among others, headache, coughing, fever, muscle pain, etc. Influenza viruses can affect humans and different animals such as, for example, cats, dogs, birds and horses. There is evidence showing cross-species influenza virus transmission. For example, it has been shown that the influenza type A virus can be transmitted from one species to another (for example, between humans and pigs). In these cases, cross-species transmission information may indicate how much potential a virus has to cause a pandemic in the new host by analyzing the severity and infectivity of the virus in the original host.
