1. Explain: Why does a campfire warm you up on a cold night?
2. Explain: How food is cooked when it is placed in the oven?
3. Explain: Why the inside of an automobile left sitting in direct sunlight for several hours?

Answers

Answer 1
1) heat flows from hot to cold. the heat from the fire is let off from the exothermic reaction of the fire and warms up the surroundings, including yourself.

2) food is cooked in the oven by heat transfer. the heat warms up the pan and thru conduction, the food is heated and cooked.

3) I'm guessing this question is y it heats up? the answer to that is that the heat waves from the sun is absorbed into the car from radiation and thru convection the whole car is heated
Answer 2
Back to helping Wajiha! Wonderful!

1. Well, to begin the combustion reaction of burning organic material is exergonic. Basically meaning it releases energy. In the case of a campfire, it would be heat energy. This energy is stored in the wood by the process of the wonderful photosynthesis and the heat energy causes the air around the campfire to gain that energy into its system. You feel the heat energy because the difference between your body temperature and the air around you is decreased due to the heat from the fire, meaning you are losing less heat in the outside environment. That would be classified as a radiation heat transfer.

2. Depending on what oven you use. There are two type, gas and electric. However, what is common about these two is that they emit thermal radiation, either baking (heated below the food) or broiling (heated about the food) the food. They take electricity and convert that into convection thermal radiation where a metal element gets heated up, causing the food to cook.

3. And last but not least, I believe what you are asking is why is the inside of an automobile hot after it has been left sitting in direct sunlight for several hours. There is a phenomenon known as the Greenhouse Effect. Basically the sunlight travels from the sun in the visible part of the spectrum. The sunlight is then absorbed by the surface of the car and the surface begins to absorb the sunlight's radiated energy and that is what makes the inside of the car hot.

Have a nice day!

If the environment change suddenly for example because of global warming, do you think generalist or specialist species would be better able to adapt and avoid going extinct? Why?

Answers

generalist because specialist species have a very specific niche. they can only live in certain conditions and eat certain things but generalists have a broader range of living conditions and food sources. ex: specialist = giant panda generalist = humans. generalists can just switch to another environment or food source and that kind of thing
Final answer:

Generalist species would be better able to adapt and avoid extinction compared to specialist species in the case of sudden environmental changes like global warming.

Explanation:

In the case of sudden environmental changes like global warming, generalist species would be better able to adapt and avoid extinction compared to specialist species. Generalist species are able to tolerate a wide range of environmental conditions and utilize different resources, which provides them with greater flexibility in changing environments. Specialist species, on the other hand, are highly adapted to specific ecological niches and rely on specific resources, making them more vulnerable to changes in their environment.

The vast majority of juvenile court adjudications are

A. tried by jury.
B. conducted in adult court.
C. uncontested.
D. dismissed.

Answers

Final answer:

The vast majority of juvenile court adjudications are often uncontested, meaning no formal trial by jury is held. These proceedings are typically less formal than adult trials and focus on rehabilitation.

Explanation:

The vast majority of juvenile court adjudications are C. uncontested. This implies that the defendant does not contest the charges, leading to decisions without a trial. Unlike what's often shown on television, the representation of courtroom drama with a jury present is not a common occurrence in these cases. Many juvenile cases are not tried by a jury because the constitutional right to a jury trial in juvenile court proceedings is not as clear-cut as in adult criminal courts. Moreover, juvenile cases are often focused on rehabilitation rather than punishment, and the procedures can be more informal compared to adult court proceedings.

In general, criminal cases in the United States do involve the right to a trial by an impartial jury, but this right can differ for juveniles in certain jurisdictions. Juvenile court adjudications may be resolved through plea agreements or by the judge's decision, which simplifies the legal process. It's crucial to remember that the objective of the juvenile justice system is to guide and reform, as opposed to just punishing offenders.

Someone who has vision in only one eye can no longer use _____ as a cue for the perception of depth and distance.

Answers

Binocular cues--particularly retinal disparity and binocular convergence

Binocular cues are information (depth/distance) taken in by both eyes. The two main types of binocular cues are retinal disparity and binocular convergence. 

Retinal disparity arises from the fact that our left and our right eyes, being a few centimeters apart, view images at slightly different angles. The two different images are merged into one and this allows us to perceive depth in the things we see around us. 

Binocular convergence is the simultaneous inward movement of both eyes in order to maintain a single binocular vision. The closer the object is, the more inward rotation is required for the eyes. The degree of rotation of the eyes helps the brain to interpret the distance of the perceived objects.

A child has sickle-cell disease ( ss ) but neither parent is ill. What must be true of her parents’ genotypes?

Answers

The parents must both have the recessive gene to have had the child with the disease.

Hopefully this helps! :)

Answer:

Her parents are heterozygous carrier for the disease and have genotype "Ss"

Explanation:

Sickle cell disease is a recessive disorder and is expressed in homozygous recessive genotype only.

Since the child is affected with sickle cell anemia, her genotype is "ss".

To get "ss" genotype, both her parents should have at least one copy of "s" allele. Since both the parents are not affected by the disease, they are heterozygous for the allele. Both the parents have genotype "Ss" and are serving as carriers for the disease.

The phoshorous cycle differs from the carbon cycle in that: none of the above the atmosphere does not contribute to part of the phosphorus cycle plants play a role in the carbon cycle, but have no role in the phosphorus cycle there is little or no human impact on the phosphorus cycle phosphorus is not a critical component of living organisms

Answers

Uh i dont know this one this is difficult.
Final answer:

The phosphorus cycle differs from the carbon cycle as it does not involve the atmosphere, instead it is often the limiting nutrient in ecosystems and cycles through geologic processes. Human activities affect the phosphorus cycle through the use of fertilizers, and phosphorus is critical for organisms, being part of nucleic acids and bones.

Explanation:

The phosphorus cycle differs from the carbon cycle notably in that the atmosphere does not contribute significantly to the phosphorus cycle. While carbon cycles quickly between organisms and the environment through processes such as cellular respiration and photosynthesis, phosphorus is often the limiting nutrient in ecosystems and does not have a gaseous form that is readily available to organisms. Instead, phosphorus typically cycles through geologic processes like weathering and erosion, water drainage, and the movement of continental plates. In aquatic systems, particularly freshwater ecosystems, phosphorus is a critical component for growth. Plants do indeed play a role in the phosphorus cycle, aiding in the uptake of phosphorus from the soil with the help of mycorrhizal fungi.

It is not true that there is little or no human impact on the phosphorus cycle; excessive use of phosphorus in fertilizers can lead to nutrient overload and eutrophication in water bodies. Lastly, phosphorus is absolutely a critical component of living organisms, comprising nucleic acids, phospholipids, and as calcium phosphate, it is a major element in bones.

A man is stricken with a type of hemophilia that is an X-linked recessive genetic disorder. His mother is a carrier of the disease, but his father is not a carrier and is not affected by the disease.

Hemophilia A is an X-linked recessive disease caused by a lack of a coagulant, or blood clotting agent, called factor VIII (factor 8). This is caused by a mutation in a gene on the X chromosome called F8. If a father is affected, his daughters will be carriers of hemophilia A and his sons will be unaffected. If a mother is an unaffected carrier, each daughter has a 1 in 2 chance (i.e., 50%) of being an unaffected carrier and each son has a 1 in 2 chance (i.e., 50%) of being affected with hemophilia A.

Which of the findings listed below support the dopamine hypothesis? amphetamines decrease dopamine and produce the positive symptoms of schizophrenia. amphetamine-induced psychosis is less likely in persons with a genetic predisposition for schizophrenia. drugs that block the effects of dopamine in the brain reduce or eliminate symptoms of schizophrenia. amphetamines decrease dopamine and can produce the negative symptoms of schizophrenia?

Answers

The dopamine hypothesis of schizophrenia is a structure, accrediting indications of schizophrenia to a distressed and agitated dopaminergic indicator transduction. The growth of enriched antipsychotic medicines was directed by a hunt for dopamine blockers founded on the notion that schizophrenia is, partly, a hyperdopaminergic state. So from the choices given above, it can be concluded that, drugs that block the effects of dopamine in the brain reduce or eliminate symptoms of schizophrenia.

Final answer:

The dopamine hypothesis of schizophrenia is supported by evidence that antipsychotics, which block dopamine, alleviate symptoms, and that amphetamines, which increase dopamine, can induce psychotic symptoms. Amphetamines do not decrease dopamine levels but rather increase them.

Explanation:

The dopamine hypothesis of schizophrenia suggests that symptoms of the disease are related to the dysfunction of dopamine neurotransmission in the brain. Two of the findings that support the dopamine hypothesis are that drugs which block dopamine effects reduce symptoms of schizophrenia and that amphetamines, which increase dopamine release and block its reuptake, can induce psychosis resembling the positive symptoms of schizophrenia. Amphetamines do not decrease dopamine but rather increase its levels, which can produce symptoms similar to the positive symptoms observed in schizophrenia, not the negative ones.

Antipsychotic medications, known as dopamine antagonists, help treat schizophrenia by decreasing dopamine neurotransmission. This is accomplished by the drugs binding to dopamine receptors, but without activating them, effectively blocking the neurotransmitter's effects and reducing the symptoms of the disease. On the contrary, amphetamine-induced psychosis, which is more common when there is an increase in dopamine activity, mimics the positive symptoms of schizophrenia such as hallucinations and delusions.

In pea plants tall is dominant and short is recessive. a heterozygous tall plant is crossed with a short plant. what is the expected genotype ratio?

Answers

If you were to come up with letters to represent those traits, (I used for tall and for short. Heterozygous mean that you'd have Tt, and short would have to be tt, since if you used a dominant allele, it would result in a tall trait. So Tt x tt on a punnet square would give you two of each, meaning the genotypic ratio is 2:2
Parents: Tt × tt
Possible genotypes: Tt, Tt, tt, tt.
So that's 2:2 since the plants have a 50% chance of being tall or short. 

How many phosphoester (phosphate ester) and phosphoanhydride bonds are in adenosine monophosphate (amp) and adenosine diphosphate (adp)?

Answers

The bond between CH2 and P of phosphate through O is called phosphoester bond. Only one such bond is present in both AMP and ADP.Link of phosphate groups through O by elimination of water molecule is called phosphoanhydride bond.In AMP, only single phosphate group present so no phosphoanhydride bond is present. But inADP, two phosphate groups are linked by one phospoanhydride bond.AMP  1  0ADP   1  1

Answer: The correct answer is -

The number of phosphoester bond in-

AMP (adenosine monophosphate) = 1

ADP ( adenosine diphosphate) = 1

The number of phosphoanhydride  bonds in -

AMP = 0

ADP = 1

Phosphoester bond is formed when the alpha phosphate (that is the first phosphate) present in ADP and AMP links to the 5' carbon of ribose sugar through oxygen.

On the other hand, Phosphoanhydride bond is formed between two phosphate. As ADP has two phosphate, thus it contains one phosphoanhydride bond and the first phosphate is linked to ribose via one phosphoester bond.

AMP has single phosphate, so no phosphoanhydride bond is there, only one phosphoester bond is present in it.

For the enzymatically catalyzed reactions shown below, classify the enzymes as oxidoreductases, transferases, hydrolases, lyases, isomerases, or ligases. answer parts (a), (b), and (c). g

Answers

Final answer:

The enzymes are classified into different groups based on the type of reaction they catalyze. Oxidoreductases are involved in oxidation-reduction reactions, transferases in the transfer of a functional group between molecules, and hydrolases catalyze the hydrolysis of a compound. However, without the specific reactions, it is hard to definitively categorize the enzymes.

Explanation:

In Biology, enzymes are grouped into categories based on the type of reaction they catalyze. There are six main classes: oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases.

(a) Oxidoreductases: These enzymes are involved in oxidation-reduction reactions, where electrons are transferred from one molecule (the reductant) to another (the oxidant).
(b) Transferases: These enzymes catalyze the transfer of a functional group (e.g., a phosphate group) from one molecule (the donor) to another (the acceptor).
(c) Hydrolases: These enzymes catalyze the hydrolysis (breakdown using water) of a compound.

Unfortunately, without the specific reactions, it is difficult to definitively categorize the enzymes. You would need to see the reaction to determine whether it involves oxidation-reduction (oxidoreductase), the transfer of a group (transferase), or the breakdown of a compound with water (hydrolase).
