[i]explain your answer in terms of particle arrangement and temperature change [ii]name the process described by the change above
Answer:
Volume of air increases.
Explanation:
The volume of air increases in the syringe when the syringe is placed in hot water because the volume of air increases when the temperature is increases. According to Charles's Law which states that, at a fixed pressure, the volume of a given amount of gas is directly proportional to its temperature so if there is increase in temperature so the the volume of gas present in a container or syringe increases and vice versa.
A scientist studying fossils in undisturbed layers of rock identified a species that appeared to not have changed a lot over the years. Which observation would have most likely led him to this conclusion?
Answer:
After studying the fossil, the person can figure out which animal it might be of the records of animals we know of, by taking bone tests, etc. they can see the DNA of the animal. The bone structure can show the animal looked different, or even could figure that out through the DNA. During the years, it could've mated with other animals creating an updated breed, or simply just changing to fit into new environments aka evolving

how many molecules are in 2fe203
Answer:
2 molecules.
Explanation:
In 2Fe203, there are two molecules because Fe203 is a molecule which is made up of two atoms i.e. iron and oxygen atom. In one molecules of Fe203, there are 5 atoms so in 2 molecules of Fe203, there are 10 atoms. The digit present in front or to the left side shows number of molecules so that's why we can say that there are only two molecules in 2Fe203. The name of this molecule is iron oxide.

Note: the - symbol represents either a dominant or recessive allele.
F1) child with continuous hairline and long fingers → aabb
Each parent provided one allele for each trait to the child. So the child inherited one recessive allele a and one recessive allele b from EACH parent. The fact that both parents could provide one recessive allele to the child for each character, indicates that both parents are heterozygous for the trait. It is the only way of having a child who expresses the double recessive trait.

Explanation:
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
can someon please help me understand better DNA and chromosomes etc..???
Answer:
An organism has the same chromosomes for its entire life. The chromosomes are located within each cell nucleus. They provide the directions for how the cell is supposed to function and determine some characteristics about how the individual looks. Each chromosome contains a very complex molecule called DNA.
Deoxyribonucleic acid (DNA) is an organic chemical that contains genetic information and instructions for protein synthesis. It is found in most cells of every organism. DNA is a key part of reproduction in which genetic heredity occurs through the passing down of DNA from parent or parents to offspring.

Alina notices that when she shines a desk lamp on a mirror, nothing happens.When she shines an infrared lamp on the mirror, the mirror starts to get warmer.Why does light from the infrared lamp warm the mirror when light from the desk lamp does not?
Answer:
Because the infrared lamp gives off a type of light that the desk lamp does not, and the mirror can only take in the energy from the infrared light.
Explanation:
Answer:
Explanation:
Infrared is used for incubators when a chicken egg is about to hatch. It is the electrical frequency of electromagnetic radiation the provides heat.
Because heat is produced electrically it can be controlled with something resembling a dimmer switch (the kind of switch that dims lights in romantic restaurants). That means that the temperature can be set to the hen's body temperature.
Infrared is just below visible light.

How is efficiency related to systems?
Answer:
The efficiency indicates the manner in which the inputs are used by the system. Being efficient means the system uses inputs in a `right' way. If the input-output ratio is adverse, we say that the system is inefficient though it produces the desired output.

Una carga de 50 N unida a un resorte que cuelga verticalmente estira el resorte 5cm. El resorte se coloca ahora horizontalmente sobre una masa y se estira 11cm.
Answer:
-110 N
Explanation:
Una carga de 50 N unida a un resorte que cuelga verticalmente estira el resorte 5cm. El resorte se coloca ahora horizontalmente sobre una masa y se estira 11cm. ¿Qué fuerza se requiere para estirar ese resorte en esa cantidad?
Solution:
La constante de resorte (k) es la relación entre la fuerza (F) y la extensión (d) como resultado de la fuerza aplicada, por lo tanto:
k = F / d
Dado que F = 50 N, d = 5 cm = 0.05 m. Por eso:
k = F / d = 50 N / 0.05 = 1000 N / m
La fuerza (F) requerida para provocar un estiramiento de 11 cm se da como:
F = -kx
x = 11 cm = 0,11 m. Por eso:
F = -kx = -1000 * 0,11 = -110 N
El signo negativo significa que el objeto se tira hacia el resorte.

Why is the genetic code common to all organisms!
Answer:
Why Is DNA Considered a Universal Genetic Code? DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... All organisms also use DNA to transcribe RNA, and then they translate that RNA into proteins. Every living organism uses that same system.
Explanation:
The genetic code is universal because it is the same among all organisms. Replication is the process of copying a molecule of DNA. Transcription is the process of converting a specific sequence of DNA into RNA.
Protein-encoding genes specify the sequences of amino acids, which are the building blocks of proteins. In turn, proteins are responsible for orchestrating nearly every function of the cell. Both protein-encoding genes and the proteins that are their gene products are absolutely essential to life as we know it.
