How does the human immune system work
Answer:
The acquired immune system, with help from the innate system, produces cells (antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child's body.

Which process would change metamorphic rock to igneous rock?
Answer:
If the freshly created metamorphic rock is exposed to enough heat, it may melt and become molten (magma). Igneous rock is formed when molten rock cools. Sedimentary and igneous rocks can both create metamorphic rocks.
The process that would change metamorphic rock to igneous rock is to treat metamorphic rock at extremely high temperatures and pressure that effectively transform it into a molten state. And this molten magma cools and crystallizes completely giving rise to the production of igneous rock.
What is Metamorphic rock?Metamorphic rock may be defined as a type of rock that is significantly obtained due to the series of alterations in the pre-existing rocks. These alterations emerge due to changes in environmental conditions.
According to the context of this question, igneous forms are synthesized when the molten metamorphic rock cools and crystallizes due to the result of volcanic eruptions and melted rock inside the earth's crust. This happens due to the generation of extremely high temperatures and pressure.
Therefore, the process of formation of igneous rock from metamorphic rock is well described above.

How is energy released from ATP?
ANSWER CHOICES IN THE PIC
Answer:
Explanation:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).

How do hydrogen ions get transferred from the Light Reaction to the Calvin Cycle?
Answer:
A photon of light hits chlorophyll, causing an electron to be energized.
The free electron travels through the electron transport chain, and the energy of the electron is used to pump hydrogen ions into the thylakoid space, transferring the energy into the electrochemical gradient.
what part of the cellular respiration pathway is affected by cyanide?
The ferric ions' cytochrome oxidase in the mitochondria makes a reversible chemical bond with cyanide. By preventing the conversion of oxygen to water, this essentially stops cellular respiration.
What is the role of cyanide in cellular respiration?Heme-containing proteins include Fe3+, which cyanide binds to. As a result, the electron transport chain's terminal cytochrome complex IV is inhibited.
Cyanide's blockade of complex IV depletes ATP, which leads to cell death.
Because the molecules are so small and can disperse quickly throughout the entire body, cyanide can kill so quickly by damaging all major organs and tissues in a short period of time.
Therefore, electron transport system is affected by cyanide in cellular respiration.

how many calories are in an average trick-or-treaters halloween stash?
The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.
Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.
Considering this, in a Halloween stash the calories depend on two factors:
The types of candies or productsThe units of each oneLet's suppose there are 5 units of each of the following candies:
Chocolate barsTaffiesLollypopsCandy cornLet's now calculate the calories
Chocolate bars = 220 calories x 5 units = 1,100 caloriesTaffies = 20 calories x 5 units = 100 caloriesLollypops = 83 calories x 5 units = 415 caloriesCandy corn = 7 calories x 5 = 35 caloriesAdd all the previous results:
1,100 + 100 + 415 + 35 = 1,650 calories in total

What happens to solid particles as they are heated?
Explanation:
When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.
they vibrate when they are next to something they jump do it untill its really hot and it mealts

what is a major difference between messenger rna molecules and transfer rna molecules?
Answer:
1) Messenger RNA molecules contain ribose, and transfer RNA molecules contain deoxyribose.
2) Messenger RNA molecules function in carrying coded information to the ribosomes, and transfer RNA molecules function in carrying amino acids to the ribosomes.
The major difference between messenger RNA molecules and transfer RNA molecules is that messenger RNA carries the genetic information, while tRNA carries the amino acids.
What is RNA?RNA is ribonucleic acid. In the cell, different types of RNA are found, such as mRNA (messenger RNA), tRNA (transfer RNA), rRNA (ribosome RNA), SnRNA, miRNA, etc. mRNA, or messenger RNA, is formed from DNA. It carries the information of a cell. The three consecutive nucleotides of mRNA make up a codon. An example of a codon is AUG.
tRNA has a cloverleaf-like structure. It has different domains such as the TΨC loop, the DHU loop, the anticodon region, and at the 3' end it is attached to an amino acid. The anticodon of the tRNA reads the codon sequence of the mRNA and attaches the amino acids. For the AUG codon methionine is attached.
Hence, the main difference between the messenger RNA and transfer RNA molecules is that mRNA carries the message of the genetic material, while tRNA carries amino acids to express the genetic material on mRNA.

A substrate is a molecule that an enzyme reacts.
enzymes catalyze chem. reactions with substrates. Substrates transform into 1 or more products. released from " active site," substrate is then able 2 receive another substrate molecule.
Answer:
An enzyme is catalyzing a reaction.
Explanation:
Two substrates bind to the active site of the enzyme. The enzyme catalyzes the reaction (lowers the activation energy needed to complete the reaction), and the result is the final product: two substrates bound together, and an enzyme that can go on to catalyze more reactions.
