Cohesion, surface tension, and adhesion are the properties of water molecules that ________
Answers
Answer:
Hydrogen bonding
Explanation:
Hydrogen bonds between surface water molecules resist being stretched.
Cohesion, surface tension, and adhesion are the properties of water molecules that are all a result of hydrogen bonding.
Hydrogen bonding is a transient intermolecular force caused by the electrical attraction between partially positive hydrogen atoms and partially negative F, O, or N atoms.
The attraction between partially positive hydrogen atoms and partially negative oxygen atoms of adjacent water molecules that form hydrogen bonding takes place in water.The differences in electronegativity between hydrogen and oxygen atoms lead to associated properties that are Cohesion, surface tension, and adhesion. Cohesion - Attraction between water moleculesAdhesion - the attraction between the water molecules and other compounds.The surface tension - sticking of water molecules to one anotherThus, the correct answer is - are all a result of hydrogen bonding.

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.

Your teacher gives you a task in science class. You must decide which of the five samples you are given are alive or were once alive. One specimen is a crust gray-green object. What is the BEST clue you could use to decide: living thing or not a living thing.
A) Does it move?
B) Does it have DNA?
C) Is it made of cells?
D) Can it make its own food?
Answers
The best clue that can be used to decide living thing or not a living thing is the observation of living or dead cells present in the specimen. All the living or dead organisms exhibit cells. Cell is a structural and functional unit of life. The growth and metabolism of living organism are dependent upon a cell. A cell in a life form exhibit organelles and components which are not found in non-living objects
The BEST clue you could use to decide: living thing or not a living thing- is option C. is it made of cells and
The living things have some basic characteristic features of life in them that help in determining if an object or thing is living or nonliving thing. these characteristic can be present in all or some, are as follows:
Cellular organization - made of cell is very basic trait of life of every living being.the ability to reproduce - it is present in almost every living thing it could be sexual or asexual.growth & development - living things grow and developenergy use - use energy to perform various functionshomeostasis - regulate according the environmentGenetic material : it can have DNA as genetic materialthus, there is two options only that present in every living organism that are made of cells and presence of DNA, but for DNA one need to investigate thoroughly so the correct answer is - C) Is it made of cells?

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
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.
What does glycolysis process?Glycolysis is the method of breaking down glucose. Glycolysis can take place with or without oxygen. Glycolysis produces two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water.
Glycolysis occurs in the cytoplasm.

prostate cells usually require testosterone and other androgens to survive. but some prostate cancer cells thrive despite treatments that eliminate androgens. one hypothesis is that estrogen, often considered a female, may be activating genes normally controlled by an androgen in these cancer cells. desribe one or more experiments to test this hypothesis
Answers
One can check for the translation and transcription of genes of interest in the absence of androgens, one can check whether the estrogen is involved in the expression of oncogenic proteins of interest by depleting the estrogen, and one can also examine the existence of estrogen receptor complex in the prostrate cancer cells nuclei.
• One can check for the translation and transcription of genes of interest in the non-existence of androgens and if these genes are expressed then this suggests that apart from androgens other factors also affect their expression.
• One can deplete the estrogen from cancer cells and if the involvement of estrogen is there in the expression of oncogenic proteins of interest then its reduction will result in diminished multiplication rates in cancer cells.
• One can also test the existence of estrogen-receptor complex in the prostate cancer cells nuclei to confirm that estrogen is taking part in the regulation of gene expression.
Thus, various experiments can be conducted to check that whether the expression of genes controlled by the androgens under normal conditions are affected by the presence of estrogens in prostate cancer cells.

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.

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