Why does water have a high surface tension? (2 points) Group of answer choices The lengths of the bonds in water molecules can change. Water molecules contain 18 electrons. Hydrogen bonding keeps water molecules close together. Water is a liquid at room temperature.
Answer:
Water's high surface tension is due to the hydrogen bonding in water molecules. Water also has an exceptionally high heat of vaporization. ... Water's heat of vaporization is 41 kJ/mol. Vapor pressure is inversely related to intermolecular forces, so those with stronger intermolecular forces have a lower vapor pressure.please help me with my biology!!!

Deep ocean technology has allowed scientists to discover and study organisms living near deep-sea vents. Unlike surface organisms, these organisms survive on a food web based on chemosynthesis instead of photosynthesis. Deep-sea vent organisms live in complete darkness under extreme pressure. What are deep-sea vent organisms evidence of?
Answer:
Evolution.
Explanation:
The deep-sea vent organisms are the evidence of evolution because these organisms evolve with the passage of time and able to survive the extreme environmental condition of the deep sea vent. Evolution is the change in the characteristics of a species with the passage of several generations and relies on the process of natural selection. This evolution helps the organisms to adopt the surrounding environment and able them to survive in it.
Answer:
These organisms depend on sulphur coming form the vents.
Explanation:
A hydrothermal vent is a fissure on the seafloor and is geothermally heated by the hot magma from below. They exist due to the tectonic activity of the earth. These hydrothermal vents are found along the mid-oceanic ridges They are located where the new crust is formed. Most of the deep-sea creature tends to thrive in these vents. These creatures have adapted to the high temperature and pressure changes and mainly adapted through symbiosis. They make use of sulphur gas coming from these vents to sustain themselves.carol has an unknown element in group 7. Using the periodic table, how many valence electrons does her element have?
A.) Five
B.) Seven
C.) Nine
D.) Seventeen
Answer: seven
Explanation: the valence electrons are the numi of electrons found in the outermost shell of an element. The group of an element indicates it's number of electrons in the outermost shell while the number of shells occupied by electrons indicates the period.
Thus since the element is in group seven it has seven valence electrons.

Can humans ever directly see a photon?
Answer:
Yes humans can directly see a photon.
Explanation:
In fact, photons are the only things that humans can directly see. A photon is a bit of light. Human eyes are specifically designed to detect light.
This happens when a photon enters the eye and is absorbed by one of the rod or cone cells that cover the retina on the inner back surface of the eye.
For Example
When you look at a chair, you are not actually seeing a chair. You are seeing a bunch of photons that have reflected off of the chair.Thus, Yes humans can directly see a photon.

Cheetahs and lions live in the same regions and eat the same food sources, such as gazelles and small wildebeests. Because of this, when food is limited, they often have to fight to survive.
is this mutualism, parasitism, or commensalism?
None of these answers seem to fit because the relationship between the cheetahs and lions is a competitive relationship, while mutualism, parasitism, and commensalism are all symbiotic relationships.
Cheetahs and lions live in the same regions and eat the same food, thereby it can be described as an interspecific-competition relationship.
What is competition?Competition is an ecological relationship where two species are confronted with limited resources (e.g. food)
Mutualism is an ecological relationship where both species are benefited from their interactions.Parasitism is an ecological relationship where one species is benefited whereas the other is harmed from such interactions.In conclusion, cheetahs and lions live in the same regions and eat the same food sources, thereby it can be described as an interspecific-competition relationship.

how do turtles interact with the abiotic factors in their environment?
Answer:
An abiotic factor that affects sea turtles is hurricanes, hurricanes affect sea turtle's nests placed on the beach, they get destroyed by hurricanes if not moved into a secure place.
Explanation:
Turtles remarkably interact with abiotic factors like water, air present in the sea, and various abnormal circumstances like floods and hurricanes.
What are Abiotic factors?Abiotic factors may be defined as those factors that significantly deal with the non-living part of an ecosystem that shapes its environment.
It includes climatic factors like temperature, light, rain, fire, winds, etc., topographic factors like mountains, hills, plains, deserts, etc., and edaphic factors like characteristics of the soil. Both biotic factors and abiotic factors are influential for the survival of living organisms.
Turtles are positively influenced by water. The nesting of turtles assists beaches by depositing their eggs in the sand. They typically get nutrients from beach grasses that help to prevent coastal erosion. The place which best suited their adaptation is excessive water present.
Therefore, abiotic factors like an aquatic ecosystem, water, winds, certain abnormal situations, etc. through which turtles interact.

what is a complex sugar
Answer:
Complex Carbohydrates: Also know as polysaccharides (poly = many), these carbohydrates have more than two units of glucose (sugar) linked together. Polysaccharides are generally not sweet and are not water soluble. Starches and dietary fiber are complex carbohydrates.
Complex carbs pack in more nutrients than simple carbs. They're higher in fiber and digest more slowly. This also makes them more filling, which means they're a good option for weight control. They're also ideal for people with type 2 diabetes because they help manage blood sugar spikes after meals.
Simple carbs — also known as simple sugars — contain one or two sugar molecules, whereas complex carbs have three or more. A simple sugar may be a mono- or disaccharide.
three effects of constipation
1. Infections
If you end up being constipated, you are probably having trouble passing a stool. If the stool has become dry and hard from lack of moisture, it could make having a bowel movement painful. When the rectum is stretched out to accommodate the painful stool, the rectum could stay open resulting in rectal prolapse. This could lead to an infection.
2. Bad breath
One unusual side effect is bad breath. You may wonder how a condition that is occurring at one end of your body could affect the complete opposite end of your body, but it can. What happens is the gasses and toxic waste that are building up because you are constipated rises up and as it goes throughout the body and it usually ends up in your mouth.
3. Lowered ratio of healthy bacteria
Healthy bacteria in your body is called flora. The purpose of flora is to help with the production of vitamins and helps with your immune system. When you are constipated the amount of flora in your intestine is reduced putting you at risk for illness and infection.
Extra Options
4. Colon cancer
The colon is meant to store a couple of pounds of stools. If you become constipated, there is a buildup of stools and puts the colon at risk for ripping. When the colon becomes strained because it is overloaded, it strains the inner membrane. Ruptures and possible infections occur and it could lead to colon cancer.
5. Increased toxins
Your skin will show on the outside what your body is going through on the inside. If you become constipated, you will suffer an excess of toxins in your body. The skin, your largest organ, has to work overtime to get rid of these toxins. If your skin looks less than glowing you need to address the issues that are going on inside of your body before you start looking for a new facial cream.

What is speciation? What are the causes of speciation? How does isolation lead to speciation?NO LINKS PLEASE
The biological species concept tells us that organisms belong to the same species if they can breed to produce fertile and viable offspring. Speciation is therefore the development of reproductive isolation between individuals of an original population.
This can occur in 2 different ways:
1. Allopatric speciation. This is when speciation occurs due to some sort of geographic barrier separates a population into 2 groups. These two groups can then undergo genetic divergence, where each group grows increasingly dissimilar genetically due to random mutations and natural selection acting separately in each group, or from processes such as genetic drift. It is important to recognize that the lack of gene flow between these two groups contributes to the genetic divergence of the groups. Genetic divergence can lead to prezygotic and post-zygotic barriers which prevent production of fertile/viable offspring between the 2 groups. Each of these populations now represents a new species, whose gene pools are completely separate from one another.
2. Sympatric speciation. This is when speciation occurs without the presence of any sort of physical/geographical barriers. Truthfully, this is a much less common occurence. However, it is thought that sympatric speciation can occur as a result of strong divergent selection. Sympatric speciation may also occur as a result of a polyploid individual being introduced into a diploid population.
Isolation leads to speciation by preventing gene flow between 2 groups of an original population, allowing genetic differences between the groups to accumulate over time (via natural selection, genetic drift, etc.). Over time, the accumulation of these genetic differences may result in reproductive isolation between the 2 groups, causing these two groups to be committed to separate evolutionary paths.
Answer: So, how might speciation happen?
Explanation:
Speciation describes a situation where a population in a species becomes so different that it can no longer successfully interbreed with other populations of the ‘same’ species.

ACE OR EXPERT HELP PLS: Words are very similar to genes in that they use bases instead of letters to create genetic expression. If a mutation in letters makes a new word meaning, what would a mutation in bases create?
Answer:
A mutation could create a difference in the sequence of the codons which could potentially create a different outcome in amino acids. Letters create words and bases create codes for amino acids. If a letter changes in a word than the meaning of the word may change, correspondingly if a base changes ( or a mutation occurs ) in a nucleotide the outcome of the amino acid may change.
