Do not worry, I can- but will not- hurt you. Your family, however, doesn't have such luck. Do not warn them that I will be following their every move, or it will lead to a grizzly fate for you and your bloodline. I hope that my message has given you closure for the events to come.
In the meantime, you can pray for your family. Maybe I'll have mercy.
The best procedure for a scientist to use in order to determine how many calories are in a certain food is burn the food and determine how much it raises the temperature of a known amount of water. Option C is correct.
When food is burned, it releases thermal energy in the form of heat. The amount of heat energy released can be measured by observing how much it raises the temperature of a known amount of water. This is because water has a specific heat capacity, which means it requires a certain amount of energy to raise its temperature.
By burning the food and using a calorimeter (a device used to measure heat), scientists can accurately measure the amount of thermal energy released. This energy can then be converted to calories, which is a unit of energy commonly used to measure the energy content of food.

Answers
The gas leaves the atmosphere as plants use it to make sugar.
Carbon dioxide is used from the atmosphere and then converted into sugar by plants by the process of photosynthesis.What is carbon cycle?The carbon cycle is way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.Plants use carbon atoms in the form of carbon dioxide that is then converted into sugar.Hence, D option is correct.

The three types of specialized cells include:
Nerve cellReproductive cellMuscle cellsSpecialized cells are those cells that makes up organ systems of the body.
These cells are interdependent on other cells in the organism.
Their specialization enables them to carry out their functions efficiently.
Organelles are those membrane-bound structures that are found with each specialized cells.
But each specialized cell might need organelles in greater numbers than the generalized cell. These organelles include:
Dendrite and axon: These are organelles found more in the nerve cells of the nervous system than other generalized cells.Mitochondria: These are found more in reproductive cells and muscle cells because they require energy generated by the mitochondria for their movement.Learn more here:

How can we differentiate between daughter cells, parent cells according to their genetic material?
Answers
Answer:
idk, wait a minute and i search the question in internet and i tell u the answer
Answer:
In mitosis, parental cells and daughter cells are identical, while in meiosis the daughter cells possess half of the chromosomes of the parental cells and recombined genetic material.
Explanation:
Eukaryotic cells have two types of cell division, mitosis for somatic cells and meiosis for sex cells or gametes.
In mitosis, two daughter cells identical to the original one originate from a diploid cell. It is the division on which the growth, development and repair of tissues depend. Meiosis implies a reductive cell division, so from a diploid cell haploid daughter cells, called gametes, are originated. In addition, in meiosis, recombination of genes occurs through crossing over.There is no difference between parental cells and daughter cells in mitosis, but daughter cells in meiosis have half the chromosomes of the original cell and their genetic material is recombined.

How are photosynthesis and cellular respiration different
(Hint: look at the inputs/reactants and outputs/products)?
Answers
Photosynthesis and cellular respiration are similar in the sense that they both carry out chemical reactions that release something into their environment.
Cellular respiration differs from photosynthesis because it used oxygen to make carbon dioxide, while photosynthesis uses carbon dioxide to make oxygen.

1)) The average depth of a lake is 10 meters. Do you think sunlight acts a limiting factor the same way it does in the ocean? Why or why not?
2)An area with a high population of crayfish in local lakes and rivers has begun experiencing acid rain, rain that has a pH of 3.0 - 4.0. Predict how this rain will impact the crayfish population.
Answers
Answer:
No.
Explanation:
No, the sunlight does not act as a limiting factor the same way it does in the ocean because the lake has lower depth as compared to ocean which is very deep i. e. more than 3000 meters where sunlight does not reach and we know that sunlight is very important for the survival of plants. Sunlight reach in the water about 1000 meters so plants can survive and do photosynthesis due to its low depth.
Acid rain will impact the crayfish population because acid rain decreases the pH of water and this lower pH causes death of the crayfish and also the food of crayfish and thus lower the population of crayfish due to unavailability of food..

A. family
B. peer
C. adoption
D. twin
Please select the best answer from the choices provided
Answers
Answer:
B. Peer
Explanation:
When looking at studies relating to the heredity of traits we want to see if the child got a trait from the parents and their genes or from the way the child grew up with the parents. That means that peers are not useful to us in those studies. Family is very useful since we need to look at the family and how it raises a child. Adoption is useful to see if an adopted child has the same traits as a biological child. And twins are useful if they grew up in different circumstances from one another.

Is using fossil fuels in generating electricity better or using renewable energy? why?
Answers
Answer:
Explanation:
Using renewable energy will always be better than fossil fuels.
This is because fossil fuels need a very long time to renew themselves. And we will run out of them long before they can renew themselves. Besides this, there is a more concerning and very alarming issue with using fossil fuels instead of other energy sources. Global warming and environmental destruction is a very big problem for us in the 21st century. The air is more and more polluted. Temperatures are rising and oceans are rising with them. We will lose the ability to grow food and raise animals in the future if we continue like this.
Which is the pathway for information through a neuron? dendrite → axon → cell body → axon terminals axon terminals → axon → cell body → dendrite dendrite → cell body → axon → axon terminals cell body → dendrite → axon → axon terminals
Answers
Answer:
dendrite → cell body → axon → axon terminals
Explanation:
The pathway for information through neuron are dendrite → cell body → axon → axon terminals and this because Dendrite is the input zone of nerve cell where neuron can receive information from another nerve cell.
Cell body is the part of the neuron that contain nucleus and it is link to the dendrites and it send signals to the axon.
Axon is a long nerve cell that join the cell body at a terminal called axon hilock and this conduct electrical impulses.
Axon terminal contain synaptic vessicles and it is synapse to other terminal and it is the out put zone of neuron. It is the out put zone where information is expell out

You have two pure substances that you cannot identify each sample is solid at room temperature describe at least five steps in the appropriate sequence that you would take to be able to identify the substances
Answers
Answer:
Explanation:
If we have two solid samples, in order to identify what they are a series of ordered steps have to be performed.
1) The first thing to do is to observe the sample. If there is color it may indicate the presence of certain anions: for example if the sample is purple, it can be because of the presence of the permanganate ion (MnO₄⁻), if it is yellow it can be chromate ion (CrO₄⁻), if it is orange it can be the dichromate Cr₂O₇²⁻), etcetera. If the color of the sample is white we have no indication whatsoever.
2) Then we can use certain reactants to precipitate the cations of the sample. For example, we can add first HCN 3N to our sample. If there is precipitation, it means that the cations Ag⁺ or Pb²⁺ are present. If not, there are other cations and we must use a different reactant to precipitate them.
3) We then add H₂S to the sample (not adding it per se, but generating it heating thioacetamide with water). If we see a black precipitate, it can be because of the cations Pb²⁺, Bi³⁺ or Cu²⁺. If we see a yellow precipitate, it corresponds to Cd²⁺. If we do not see a precipitate, we need to add other reactant.
4) We add NaOH to the sample. If we see precipitate, it can be because of the the ions Fe³⁺, Ni²⁺, Co²⁺ or Mn²⁺.
5) We observe the color of this precipitate. If it is brown is Fe(OH)₃, if it is green is Ni(OH)₂, if it is pink is Co(OH)₂, and if it is white is Mn(OH)₂.
Se toma la muestra problema o alícuota y se añade HCl 2N. Con este reactivo precipitan los cationes del Grupo I ( Plata (I), Plomo (II) y Mercurio (I)): AgCl, PbCl2 y Hg2Cl2. Sobre el mismo embudo se añade agua de ebullición, quedando en el papel de filtro el AgCl y el Hg2Cl2; el Pb2+ puede identificar añadiendo KI, que origina un precipitado de PbI2 que se disuelve en caliente, que sirve para identificarlo mediante la llamada lluvia de oro.1
Sobre el mismo papel de filtro se añade NH3 2N. En el papel de filtro si existe Hg22+ y se forma una mancha blanca, gris o negro, que es una mezcla de HgClNH2 y Hg0. En la disolución se forman Ag(NH3)2+, que se puede identificar con KI dando un precipitado de AgI amarillo claro.
