The agents of metamorphism are _______.
a. uplifting and folding
b. foliation and deposition
c. contact and regional deformation
d. heat, pressure, and chemical fluids
e. slaty and platy cleavage

Answers

Answer 1
The agents of metamorphism are heat, pressure, and chemical fluids.
Answer 2

The agents of metamorphism are  heat, pressure, and chemical fluids. Hence, option (d) is correct.

What is metamorphism?

The process of metamorphism involves changing the protolith, an existing rock, into a new rock with a different mineral composition or texture. The rock remains essentially solid throughout the metamorphism process, which happens at temperatures between 150°C and 200 °C (300°F and 400 °F), as well as frequently at high pressures or in the presence of chemically active fluids. Weathering and diagenesis, which are changes that occur at or near the Earth's surface, are not the same as metamorphism.

Metamorphism can take many different forms, such as regional, contact, hydrothermal, shock, and dynamic metamorphism. The typical temperatures, pressures, and rates at which they occur, as well as the degree to which reactive fluids are involved, vary between these. Prograde metamorphism is that which occurs under conditions of rising pressure and temperature.

Explain the law of large numbers. how does this law apply to gambling​ casinos?

Answers

The law of large numbers states that when a random process is repeated many times, the frequencies of the observed outcomes get increasingly closer to the theoretical probabilities. This law of numbers work to the advantage of casinos. The advantage is because when the player's risk is concentrated on little numbers of rounds or hands, the casino's risk is spread out among all the games and bets that are in play.
Final answer:

The law of large numbers is a principle from probability theory, stating that as you repeat a probability experiment, the relative frequency of events tend to approach their theoretical probabilities. In a gambling context, this means that while short-term results can be unpredictable, over the long run, outcomes conform to their theoretical probabilities – which is why casinos, which always have a slight edge, tend to win over the long haul.

Explanation:

The law of large numbers is a key principle in probability theory and statistics, stating that as a probability experiment is repeated more times, the relative frequency of an event tends to get closer to its theoretical probability. This means that the more times you repeat the experiment, the closer the outcomes will be to what you would theoretically expect based on probability.

Applying this to a gambling context, let's consider the example of flipping a fair coin. If you flipped it a few times, it's quite likely you could observe solely heads or solely tails. But if you flip it many times, say thousands, the relative frequency of getting heads versus tails starts to approach the theoretical probability of 0.5. This is not to say that the outcomes happen in an orderly or predictable way but, overall, the empirical (observed) frequency starts to approach the theoretical probability.

Casinos rely heavily on this principle. For each game, the house, i.e., the casino, has a slight mathematical edge, or advantage. Over the short run, anything can happen (a player might win big), but in the long run, the casino will always come out ahead due to the law of large numbers. This can be seen in games like roulette, where the house has a 1 in 37 to 1 in 38 edge on each spin, or blackjack, where the house edge ranges between 0.2% and 2% depending on house rules and player strategy.

Rabbits are introduced into a grassland area. Which action of the rabbits would harm the buffalo that live in the grassland?
A.

B.

Answers

The most likely answer choice should and would be B, given that rabbits are herbivores (meaning that they only eat vegetation and plants, including grass). Buffalo's food source(s) and diet consists of grass as well. If enough rabbits are introduced into a grassland area, they will furthermore consume more grass, in turn limiting the food source of the buffalo. 

''Attacking'' prey doesn't necessarily make sense, given that buffalos do not 'prey' on any animal and rabbits themselves are prey.

A series of measurements were made on four skulls (descriptions of the measurements can be found in the student exploration sheet). which is most likely a modern human skull?

Answers

This question is incomplete. The question gives a choice between four skulls: A, B, C and D. The skulls are compared in a table for: Cranium/face area ratio, face angle and foramen magnum ratio.

The cranium/face area ratio relates to the size of the cranium relative to the rest of the skull, and we would expect this ratio to be fairly large for a human. The face angle relates to human faces in relation to primate faces, which are less protruded forwards (i.e., we have relatively flat faces), and the foramen magnum is the hole in the base of the skull through which the spinal column connects to the skull. In bipeds, we would expect this hole to be fairly equally distant from the back of the skull to the front of the skull, so this ratio would be closer to 1. Based on this information and the ratios given in the table, I would say that skull B is most likely a human skull.

Although the foxp2 amino acid sequence is highly conserved, humans have two unique amino acids that chimpanzees don't have. these unique amino acids are highly correlated with differences in _____ seen between chimps and humans.

Answers

The answer is language. Humans have a high degree of language acquisition and complexity compared to chimpanzees due to foxp2 proteins. Foxp2 are transcription factors that are significant in cell proliferation. The difference of 2 in 700 amino acids in the sequence makes the protein to be differentially regulated between the two species.






The right answer is language (speech, talking, or every thing related to communication skills).

Forkhead-Box P2 protein (FOXP2) is a transcription factor belonging to the Forkhead-Box3,4 protein group. it is recognized that FOXP2 plays a large role in language transmission, including grammatical abilities.

The name "speech gene" has been popularized for the FOXP2 gene. But many other vertebrates also have this gene, and FOXP2 seems to play a role in verbal communication.

what are the differences between protists and fungi

Answers

I hope this help you.
Final answer:

Protists and fungi are both eukaryotic, but they differ in cell wall composition and motility. Fungus-like protists have cellulose cell walls and can be motile, unlike fungi which have chitin cell walls and are mainly non-motile.

Explanation:

The differences between protists and fungi are found in their cellular structures and modes of nutrition. Both are eukaryotic organisms, which means they have a true nucleus. Fungus-like protists, such as slime molds and water molds, share some similarities with fungi; for instance, they are heterotrophic, have cell walls, and reproduce through spores. However, their cell walls are composed of cellulose, unlike the chitin found in fungal cell walls. Furthermore, while fungi are strictly heterotrophic and mainly non-motile, fungus-like protists can be motile during certain life stages and have more complex life cycles, which include both asexual and sexual reproduction.

An aneurysm is a traveling blood clot that becomes lodged in the brain. an aneurysm is a traveling blood clot that becomes lodged in the brain.
a. True
b. False

Answers

A blood clot is typically an embolism of some type. What happens is often plaque or some matter will build up in an area of your body, often the femoral artery in your thigh. This plaque will dislodge and travel through your blood until it becomes lodged somewhere else, often in the small veins and capillaries within the brain. This will cause typically one of three things to happen. The clot will cause reduced blood flow to a certain area causing an ischemic infarction or ischemic stroke. Depending on the area this can cause paralysis, slurred speech, blindness, deafness... etc. Another thing that can happen is it can cause a hemorrhagic stroke or bleeding out. It literally rips the vein causing blood to burst into the surrounding tissue causing much damage. These are typically much worse then ischemic attacks. The third thing is the aneurysm. The clot will lodge and cause the smooth muscle tissue of the vein to balloon out in the particular area. Nearly always, if not discovered, this ballooning will burst and cause hemorrhagic damage to surrounding tissue.

The clot can also be a large group of platelets that coagulated to repair a damaged area and dislodged and become lodged in the brain. Hence blood 'clot'. 

In short, it's true.
Final answer:

An aneurysm is not a traveling blood clot that becomes lodged in the brain, but rather a bulge resulting from a weakness in the wall of a blood vessel. If a blood clot travels to the brain, this condition is generally referred to as a cerebrovascular accident, or stroke.

Explanation:

False, an aneurysm is not a traveling blood clot that becomes lodged in the brain. An aneurysm is actually a bulge or ballooning in a blood vessel, usually an artery, caused by a weakness in the blood vessel wall. This can happen in any blood vessel, including the brain, but it's often in the aorta or the brain.

On the other hand, a traveling clot that travels to the brain is referred to as a cerebrovascular accident, or stroke, and can cause serious damage or death. It's important to note that while an aneurysm can lead to a stroke if it bursts, the two are not the same thing.

Answers

ATP, NADH, and pyruvic acid are the correct

The formula of glycosis is glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O.

What is glycolysis?

The process by which glucose is broken down into energy is called glycolysis. It produces two atoms of pyruvate, ATP, NADH, and water. Oxygen is not required for the process, which takes place in the cytoplasm of a cell. Both aerobic and anaerobic organisms are affected.

In all organisms, glycolysis is the first step in cellular respiration. The Krebs cycle follows glycolysis during aerobic respiration. Without even a trace of oxygen, the cells make limited quantities of ATP as glycolysis is trailed by maturation.

Therefore, glycolysis is the cellular respiration process that helps in generating ATP also called body currency.

Including all of the relevant anatomical structures (and ending with the activation of the cranial nerve), explain how we sense spinning in a chair. what happens when the chair is suddenly stopped

Answers

There are three semicircular canals filled with fluid in the inner ear at right angles to each other. Each senses the movement of your head along a different axis. Using all three, the brain is able to orient your body in 3D space. Tiny hairs lining the canals (hair cells) sense motion by sloshing of the water in the canals. Information from the hair cells are relayed to the brain as an interpretation of movement of the head.
During spinning in a circle, the fluid in the canals initially slosh in the direction opposite to your head's motion. However, the jelly-like material in which the hair cells are imbedded, the endolymph, adjusts to the movement of your head,causing the hair cells to straighten, and your brain no longer receives the message that you're spinning. In effect, your brain thinks that you are standing still while the the world is rotating around you. 
When you suddenly stop spinning, because of inertia, the endolymph keeps spinning. The fluid in your ear moves again in the direction in which you were spinning before, and a signal of movement is transmitted to the brain. You sense that you are moving, but you're not.  

A theoretical protein, blue2, is coded for by the blu2 gene. This protein codes for a blue pigment used by the organism to protect it from damaging UV rays from sunlight. The enzyme alterase binding to the blu2 operator halts transcription of blue2. A blu2 operator mutation causes a conformational change that does not allow alterase to bind to operator.

Answers

The question is:
What may be observed as a result of the described mutation in an individual? 

1) Skin cancer due to UV rays 
2) Darker blue pigmentation 
3) A lack of alterase for other functions it may serve 
4) The release of a different pigment color

The correct answer is B.
In this theoretical molecular cascade, we have three key parts, the blue2 gene, the blue2 operator and the enzyme alterase.
The enzyme alterase stops the expression of the blue2 gene by binding  to its operator, and therefore the blue pigment protein.
The blue2 operator has a specific binding spot for alterase. If this binding spot is changed due to a conformational change, the alterase would not be able to bind to the operator and the blue2 gene could express undisturbedly, resulting in increased concentration of the blue pigment protein.

The parents of a 6-year-old tell the school nurse that they are worried that their child will fall behind other children academically because they are not able to afford expensive toys like computer games and handheld electronic devices. which are acceptable responses by the nurse? select all that apply.

Answers

"I understand how this can be frustrating, but rest assured this does not place your child at a disadvantage academically."

"All of these expensive toys that are advertised and purchased by some people are not necessary for preschoolers. Simple toys like chalk and Legos are great."
"Do you play with your child and provide means of play through things like dolls, puzzles, crayons, and Play-Doh? These are the types of toys suggested for preschoolers."

Expensive and elaborate toys do not place a child at an academic or developmental advantage. Simple toys that require interactive rather than passive play, and that may include the involvement of the parent, are recommended to foster development.

Answer:

The nurse should say that expensive toys are not a factor responsible for the good academic development of preschoolers. She should also mention that there are simple and inexpensive toys that are perfect for children at this age. Lastly, the nurse should indicate which toys parents could buy for this child such as dolls, puzzles, crayons and Play-Doh.

Explanation:

Some educational toys help stimulate the senses and develop children's skills, for example by getting them to come to conclusions on their own. They can (and should) begin to be used even at preschool age as it is during this time that little ones begin to develop cognitive, physical and social aspects. These toys, however, need not be expensive and far-fetched. Simple toys like lego, puzzle, color pencils are great options for this.

Answers

E. coli are a species of bacteria. Like all bacteria, they have a round piece of DNA that contains most of their genetic information, but also plasmids, that contain some more. Plasmid can be passed on from bacterium to bacterium and they contain information for fighting antibiotics. Tetracycline is such an antibiotic. The process of putting a plasmid inside a bacterium is called transformation. So what the above sentence really says, is that a bacterium just got a plasmid that is probably holding the genetic information to produce proteins that fight antibiotics like tetracycline. While regular strains of E. coli might not be able to deal with tetracycline, transformed strains will probably be able to survive it. Hence, the culture will have live bacteria and the bacteria that have a plasmid against tetracycline will be favored and survive.

The transformed E. coli cell will grow even in the presence of tetracycline.

Recombination:

It is the process by which a DNA of interest is inserted into an organism.

To insure that cell  transformed or not, scientist put put an antibiotic resistance gene.This give transformed cell an ability to grow in a medium that contain antibiotics.Non - transformed cells will die.

what is the primary advantage of using heuristics rather than algorithms in solving problems? What is the primary disadvantage?

Answers

The primary advantage of using heuristics rather than algorithms in solving problems is that it can get you an answer much faster when you use logic, assuming you are dealing with a common situation. An advantage is that primary data is information the researcher has collected and worked with personally. It relates directly to that person's research or study. A disadvantage of primary data is that it is expensive to collect the data, and it often takes a long time to process the information.

The primary advantage of using heuristics rather than algorithms in solving problems is that it can provide some quick and relatively inexpensive output to the individual.

What is the Heuristics method?

The heuristics method may be defined as a type of method that significantly involves mental timesaver for solving problems in a quick way that reveals a result that is sufficient to be practical and functional given time constraints.

The primary disadvantage of heuristics is that it involves some sort of errors that are bounded to the final result. The processes of this method are highly susceptible to biases and prejudice. This is because insufficient data can be utilized in order to make quick decisions may sometimes lead to a false outcome.
