Answer:
B)hydronium
Explanation:
This chemical structure is formed when an acid is disolved into water, as the cation (H+), which comes from the acid, cannot exist as such isolated in water (H20), hence the proton (H+) will be hydrated by a water molecule (H2O)
The union between H+ and H2O is due to the pair of electrons from oxygen and positive charge from H+
Answer:
H3O+ units are also known as hydronium ions. Hence the answer is option B.
Explanation:
Hydronium ions is defined as ions that contains proteinated ions and it is present in all the aqua solutions. These ions are abundant in protons and they have less electrons in them. It is because they had donated electrons to their other forms which gives a positive sign to the ion.
Hydronium ion is produced when an Arrhenius acid is mixed with dihydrogen oxide. This iron is found in universe like in comets, interstellar things, etc.

18. Of what are phospholipids important components?
A.the double bond in hydrocarbon chains
B.the plasma membrane of animal cells
C.the ring structure of steroids
D.the waxy covering on leaves
Phospholipids are vital components of the plasma membrane of animal cells. They formulate a lipid bilayer which controls transportation of substances across the membrane.
Explanation:Phospholipids are important components of the plasma membrane of animal cells. Phospholipids form a lipid bilayer, which is the basic structure of a cell membrane. This bilayer is semi-permeable and allows the transportation of specific substances across the cell membrane. The structure of phospholipids, with a hydrophilic (water-loving) head and two hydrophobic (water-fearing) tails, make them optimal for this role in cell biology. An example of a cell-regulation process involving phospholipids is the transportation of ions and small molecules across the membrane.

Susan wants to see how different chemicals in the soil affect plant growth. Therefore, she gets all of the same type of plant, sets them up in the same place, waters them the same amount, but then puts different chemicals on each of them. What is the independent variable in Susan's experiment?
The chemicals
The plant growth
The amount of water
Where she set-up the plants
Answer:
The chemicals
Explanation:
When a scientific experiment is proposed, it is necessary that the dependent and independent variables are identified.
An independent variable is one that does not need the influence of another variable and is responsible for presenting a result that depends on its manipulation. The dependent variable, on the other hand, is one that is influenced by the dependent variable and needs its manipulation to generate a result.
In the question above, we saw that Susan wants to know what results the manipulation of different chemicals will have on plant growth. With that, we can say that chemicals are the independent variable, while plant growth is the dependent variable.

How do changes in nutrient levels affect the structure of aquatic food webs?
ANSWER:
The effects of increasing or decreasing the nutrient levels in an aquatic food webs is described in the explanation.
Explanation:
If the nutrient levels in an aquatic food web increase moderately then it will result in increased production of the primary producers and the consumers.
But if the nutrient levels are increased excessively, like in eutrophication, then the increased level of nutrients will result in overproduction of the consumers like fishes, etc. Hence, there will be a scarcity of resources like oxygen in the water to support them and this will lead to a decline in biodiversity of the aquatic food web.
If the nutrient levels are decreased, then there will be competition for resources among the species which will ultimately lead to the decline of some species from the aquatic food web.

A certain species of desert lizard digs tunnels in which to lay its eggs. The eggs must incubate inside the tunnel for several weeks before hatching, and they fail to hatch if they are disturbed at any time during this incubation period. Yet these lizards guard their tunnels for only a few days after laying their eggs.
Which of the following, if true, most helps explain why there is no need for lizards to guard their tunnels for more than a few days?(A) The eggs are at risk of being disturbed only during the brief egg-laying season when many lizards are digging in a relatively small area.(B) The length of the incubation period varies somewhat from one tunnel to another.(C) Each female lizard lays from 15 to 20 eggs, only about 10 of which hatch even if the eggs are not disturbed at any time during the incubation period.(D) The temperature and humidity within the tunnels will not be suitable for the incubating eggs unless the tunnels are plugged with sand immediately after the eggs are laid.(E) The only way to disturb the eggs of this lizard species is by opening up one of the tunnels in which they are laid.
Answer:
a. The eggs are at risk of being disturbed only during the brief egg laying season when many lizards are digging in a relatively small area.
Explanation:
Lizards work like this, some species have egg to reproduce the babies, in this case, the lizard just stay some days to watch that there are no possible risk for the eggs. If the animal is completely sure that is a safe and a good place to leave the eggs, the lizard continue to do its own life.
After some months, the baby lizard need to figure out how to survive in this new world, as his/her mother did. They need to use its instinct.

A 1cm diameter, 6 cm long core is removed from a carrot. The resulting hole is filled with corn syrup, and a glass tube is inserted into the hole to make a watertight seal. The carrot is suspended in a cup of pure water. Beginning with the carrot cells adjoining the hole, and going out to the carrot epidermal cells exposed to the water, describe what will happen to the carrot cells. Also, what will happen to the level of liquid in the glass tube and why?
✿━━━━@♥ℳg━━━━✿
[tex]\boxed{Explained\:Answer}[/tex]______________________________
✿━━━━@♥ℳg━━━━✿
■Here,The corn syrup is hypertonic to the carrot, so will take water from the adjoining cells, causing those cells to shrink, become hypertonic to their neighboring cells and to take water from them.
■Conversely the water is hypotonic, and will enter the cells in the outer of the carrot.
■Because of this water will pass from the outside of the carrot to the inside, and cause liquid in the tube to rise
Answer:
Carrot cell will swell and liquid level in glass will reduce
Explanation:
Carrot cell will absorb water and swell in due course of time as there is difference in concentration of water outside and inside the cell.
Similarly, the corn syrup remains intact from the epidermal cell of the carrot due to the glass tube. Being hyper-tonic in nature and also due to presence of water tight glass lid, it is unable to extract water from the adjoining cell; corn syrup will take water from the tube thereby further reducing the level of water in the tube
Body posture is best described as ___________.
a. a characteristic way of bearing one’s body
b. clothing and accessory decisions that individuals choose to accent their body features
c. human movement that is used to communicate messages between people
d. the way in which individuals try to present their body type
Answer:
The correct answer is c. human movement that is used to communicate messages between people.
Explanation:
Body posture comes under non-verbal communication. Most of the time people communicate non-verbally than verbally by facial expression, body posture, appearance, and gesture.
Body posture says a lot of things about a person like if a person's body posture is straight that shows that the person is focused, interested and confident but if a person has stooped posture while sitting or standing gives a message that the person is bored and lack self-confidence.
Body posture also affects the health and personality of any individual. Day to day lifestyle of modern life is hugely responsible for people's bad body posture and health issues.
Therefore, the correct answer is c. human movement that is used to communicate messages between people.
Which of the choices below reflects the balance (or imbalance) between the direction and amount of fluid that flows across the capillary walls?
A. hydrostatic pressure only
B. plasma and formed element concentration
C. blood volume and viscosity
D. hydrostatic and osmotic pressure
Answer:
The correct answer is option - D. hydrostatic and osmotic pressure.
Explanation:
The hydrostatic pressure is the pressure that is produced by the fluid at a particular point due to gravity. The hydrostatic pressure takes the material out of the capillaries.
The osmotic pressure is the pressure that prevents a true solvent to flow inward a solution through the semi-permeable membrane. It takes the material back in the capillaries. Hydrostatic pressure at the side of the artery is more than osmotic pressure thus, the overall materials through the material across the capillaries walls.
Thus, the correct answer is option - D. hydrostatic and osmotic pressure.
The correct choice that reflects the balance between the fluid flow across capillary walls is the combined effect of hydrostatic and osmotic pressure. Hydrostatic pressure, influenced by the heart's pumping action, pushes fluids out, while osmotic pressure, driven by plasma proteins, pulls fluids back into the capillaries.
Explanation:The balance or imbalance between the direction and amount of fluid that flows across the capillary walls is reflected by both hydrostatic and osmotic pressure. Hydrostatic pressure, such as capillary hydrostatic pressure (CHP), is the pressure exerted by blood against the walls of blood vessels. Osmotic pressure, particularly blood colloidal osmotic pressure (BCOP) produced by plasma proteins such as albumin, draws fluid back into the capillaries. Together, these pressures determine the movement of fluid between capillaries and interstitial spaces.
At the arteriolar end of a capillary, hydrostatic pressure is typically higher than osmotic pressure, which pushes fluids and nutrients out of the capillaries. At the venular end, the hydrostatic pressure is lower than the osmotic pressure, which facilitates the re-entry of fluid into the capillaries. Capillary hydrostatic pressure and blood colloidal osmotic pressure can be described through values such as 35 mm Hg and 25 mm Hg respectively at different points along the capillary bed, revealing when filtration or reabsorption occurs.

Five mass extinctions have occurred throughout Earth's history, the last hypothesized to have been caused by an asteroid impact at the end of the Cretaceous. Currently, scientists agree that we are in the middle of a sixth mass extinction. What is the cause of the current mass extinction?
Answer:
The cause of the current mass extinction is the anthropic activity. The consumption of fossil fuels, ocean acidification, pollution, deforestation and forced migration threaten life and have caused the disappearance of many species.
Final answer:
The sixth mass extinction differs from past events as it is caused by human actions, including habitat destruction, pollution, and overexploitation of species, marking a significant shift from natural catastrophic events to anthropogenic impacts.
Explanation:
The cause of the current, or sixth mass extinction, is significantly different from those of the past. While past extinctions were largely due to major geologic and climatic events, the sixth extinction is directly attributable to human actions. These actions include habitat destruction, overexploitation of species, pollution, and the introduction of invasive species, all of which have dramatically increased the rate of species extinction.
Unlike previous mass extinctions that were caused by events such as asteroid impacts or massive volcanic eruptions, the current crisis is the result of the activities of Homo sapiens, especially since the onset of the industrial revolution.
The cell ____________ acts as a selective barrier (or filter) regulating which compounds or particles dissolved or suspended in water are allowed to pass through the endodermis and into the vascular system.

Membrane
Explanation:
A cell membrane is a protective layer for the cell, and this cell membrane is selectively permeable, meaning that is will let some things into the cell while keeping other things out.
The cell membrane is made up of a phospholipid bilayer which contains proteins which are involve in the transport of molecules in and out of the cell.
the cell membrane has several major roles:
It protects the cells from it's surroundings.It maintains an internal environment that is different from it's external environment.It determines which particles may enter and exit the cellIn the anatomical position, the body is standing erect with the feet flat on the floor, face and eyes facing forward, and arms at the sides with the palms facing forward. Which of the following best describes the anatomical position? Select one:
A. Right and left are reversed.
B. Toes and palms are anterior.
C. Toes and palms are posterior.
D. The head is inferior to the abdomen.
E. The transverse plane divides the body into right and left portions.
Answer:
B. Toes and palms are anterior.
Explanation:
In an anatomical position, directional terms are used to describe the position of the body parts with respect to each other. Anterior, also referred to as ventral position, means the specific body part is at the front of the body or facing forward.
According to the given position of the standing body, palms are facing forward making them anterior in position. The body is standing on the floor with flat feet which means that the toes of the feet are also facing forward.
This makes both toes and palms of the given standing body to be anterior in their position.
In the anatomical position, the body is upright with eyes facing forward and arms at the sides, palms and feet facing forward. In this stance, it is accurate to say that the toes and palms are anterior (facing to the front of the body), not posterior (facing toward the back of the body).
Explanation:In the anatomical position, the body is positioned in the upright posture with the feet flat on the floor. The face and eyes facing forward and arms are positioned at the sides, with palms turned so they are facing forward as well. In this stance, it is most accurate to say that the toes and palms are anterior (B).
Anterior refers to the front of the body or positioned nearer to the head. Therefore, when standing in anatomical position, the palms and toes are indeed anterior, as they are oriented toward the front. The term posterior, on the other hand, refers to the back of the body or something further away from the head. So, in anatomical position, the palms and toes are not posterior.

How do the basic principles of inheritance, identified by Mendel in plants, differ from those in humans?
a. They are simpler.
b. There are no Mendelian traits in humans.
c. Plants don’t have alleles.
d. The number of chromosomes is different; therefore, genetic principles vary.
e. There are no differences since the basic principles are the same.
Answer:
e. There are no differences since the basic principles are the same.
Explanation:
The basic principles of inheritance as proposed by Mendel while working on garden pea are applied to all living beings including humans. The human also has discrete units that regulate genetic traits. These units are called genes.
Genes are present on chromosomes which in turn carry them from parent to progeny. Gametes formed in humans also follow the law of segregation and bear only one allele of each gene.
Two pairs of genes are independently segregated from each other which in turn leads to the production of parental as well as recombination gametes. Therefore, the concepts of genes, purity of gametes, the independent assortment of two pairs of genes, dominance are applicable to humans also.
chemical eric 8. It also turns out that he has unpredictable shock responses, so that a small cut needing three stitches left him pale and in shock while breaking his left wrist in at least 15 places did not. What hormone could be involved?
Answer:
The correct answer is- cortisol, and prostaglandins.
Explanation:
The shock response take place when the body overwhelmed with the responses due to infection or injury. The shock response is regulated by the hormones that play major role in the body to fight against these injuries and infections.
Cortisol is primary hormone related to the stress conditions that lead to increase glucose level in body and blood to repair tissue however in some condition due to cortisol production issues did not play its role as mention in the question. ACTH impacts the adrenal gland and the production of this hormone can be compromised.
High levels of prostaglandins also play a role in the healing of the injury that takes place by causing inflammation redness and pain at the site of injury.
Thus, the correct answer is - cortisol and prostaglandins.
Adrenaline (Epinephrine) is the hormone involved in Eric's unpredictable shock response. It is released during moments of stress, instigating the 'fight or flight' response. Inconsistent reactions could result from varying adrenaline release and body reactions.
Explanation:The hormone involved in Eric's unpredictable shock response could be Adrenaline, also called Epinephrine. Adrenaline is a hormone released by the adrenal glands that acts primarily in the body's response to stress, enhancing alertness, and preparing for physical expenditure, such as the 'fight or flight' reaction.
Shock response in such a scenario could be attributed to the sudden rush or lack of adrenaline. This hormone is capable of resulting in varying reactions depending on how the body releases and reacts to it, as exemplified by Eric's contrasting responses to different injuries.

Write a paragraph of at least three sentences about stem cells. The paragraph should include what stem cells are, the controversy around them, and your opinion about using them for research.
Answer:
Stem cells are cells of a multi-cellular giving rise to an unending gift of more cells of the same type. The stem cell controversy is looking at how the stem cells develop, how they are used and how they destroy human embryos. I think its a good thing the do it because it may be a big thing in the near future that they can use it for some cure or something.
Explanation:
Stem cells are a type of cell that have the extraordinary ability to transform into any specialized cell in an organism. These cells are able to differentiate, through cell divisions even if stored for long periods of time. In summary, a stem cell is able to pass through several cell divisions creating a large number of cells, capable of forming tissues, restoring organs, among many other benefits.
The great controversy surrounding these cells is that they need to be extracted from embryos. As you know, the embryo is the initial stage of a living organism and for that reason, many people believe that it is unethical to remove cells from an embryo when it does not have the capacity to allow or deny it. Other people claim that the regenerative power of stem cells should not be manipulated by humans, as it takes away the sovereignty of God in relation to life and the human body. There are also people who believe that the regeneration capacity of these cells is somewhat controversial and that the negative points of using them have not been fully explained.
However, we must see scientific research that uses stem cells as a major scientific advance, which will help countless people around the planet, such as people with osteoporosis, bone problems, cancers, among others. Such research should be encouraged, so that the problems surrounding stem cells are resolved and this technology can be used.
