Cohesion, surface tension, and adhesion are the properties of water molecules that ________
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.

18) What kind of mutation causes extensive damage in the DNA?
a. Point mutation c. Frame shift mutation b. Chromosomal mutation d.Nonsense mutation
Answer:
c. Frame shift mutation.
Explanation:
Frame shift mutation is a type of mutation which causes more damage to the DNA of the cell. It causes changes in the amino acid sequences in a polypeptide chain. Point mutation is a type of mutation in which only one amino acid changed, while on the other hand, frameshift mutation changes the whole sequence of amino acids so we can say that frame shift mutation is more damaging to the DNA molecule.

A) Does it move?
B) Does it have DNA?
C) Is it made of cells?
D) Can it make its own food?
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.

Explain the difference between sex hormones and glandular stimulating hormones
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.

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

O c. Simple columnar epithelium.
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.

Answer:
like animals plants reproduce by there parent plant from seeds there is three ways plants reproduce from wind, water and animal
animals: animal like monkey eat the fruit of the plant and throw the seed away later it will start growing
wind: when a strong winds occur it will carry plants like dandelions, swan plants away from its parents and when the wind is over it will start growing

b) Explain why a leaf cannot be tested for starch by adding iodine solution directly.
Answer:
Due to presence of waxy layer.
Explanation:
A leaf cannot be tested for starch by adding iodine solution directly because waxy cuticle covering the leaves that prevents the penetration of iodine in the leave cells. First, the waxy layer should be removed by boiling the leaves that causes disruption in the cell membranes that make easier for the iodine to penetrate in the leave cells so that's why iodine can not be tested for starch directly.

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
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.
