As the energy of a wave length increases the length gets shorter.A wave with low frequency would have relatively low energy and a long wavelength.
What is Wavelength?A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles.
The wavelength is more frequently described in nanometers (nm), which are units of 10-9 m, or angstroms (), which are units of 10-10 m, for infrared (IR), visible light (UV), and gamma radiation.
Frequency, which is defined as the quantity of wave cycles per second, and wavelength have an inverse relationship. The wavelength of a signal decreases with increasing frequency.
Therefore, As the energy of a wave length increases the length gets shorter. A wave with low frequency would have relatively low energy and a long wavelength.

Why does liquid water have such a high heat capacity?
Choose 1 answer:
(Choice A)
Water is a nonpolar molecule.
(Choice B)
Water molecules are packed very closely together.
(Choice C)
Water is a linear molecule which makes absorbing heat easier.
(Choice D)
Water molecules are good at forming and breaking hydrogen bonds.
Answer:
Choice D
Explanation:
Water molecules exhibit hydrogen bonded to oxygen, which is considered a hydrogen bond. This is the strongest type of bond and is not easily broken. Once formed, a large amount of heat is needed to disrupt the bond energy and break apart the molecule. Therefore, water has a high heat capacity and can withstand higher temperatures than that of some other liquids.
Convert 145.0 mm to meters and express the answer to the correct number of significant digits.
Answer:
0.1450 meters
Explanation:
we know that
The magnitude of a quantity to a specific degree of accuracy is known as significant digits.
According to the multiplication and division rules of significant digits, the least number of the significant digit in any number of the problem determines the number of significant digit in the answer.
Remember that
[tex]1\ mm=0.001\ m[/tex]
so
[tex]145.0\ mm=\frac{145.0\ mm}{1\ mm}(0.001\ m)=0.1450\ m[/tex]
In 145.0 mm, there are 4 significant digits and in 0.1450 m. there are 4 significant digits.
so
The correct number of significant digits is 4
therefore
the correct answer is, 0.1450 meters

11) Which taxonomic group has the most species? Please answer ASAP
Answer: Kingdom
Explanation:
The linnaean system of classification used in taxonomy start from highest (most general category) to the lowest level as follows: Kingdom --> phylum/division --> class --> order --> family --> genus --> species.
Thus, since the first level (Kingdom) require species to have the least number of common features, the most species are found in it.
For instance: living organisms of all species are classed into just 5 kingdoms whereas over a billion species exist.

The Direct Coombs' test is a confirmatory test used to reveal the presence of blood with high accuracy. It identifies specific antibodies bound to red blood cells using hemagglutination, a process also employed in cross-match tests prior to blood transfusions.
Explanation:The answer to the question, 'Which of the following is a confirmatory test used to reveal the presence of blood with high accuracy?' is the Direct Coombs' test. This test uses a special reagent known as Coombs' reagent to cross-link antibodies bound to red blood cells, facilitating hemagglutination. Hemagglutination is the clumping together of red blood cells - a process that will occur if a person has antibodies against certain substances.
Another type of test which makes use of hemagglutination is the cross-match test, carried out prior to blood transfusion. It entails mixing a small part of the donor's red blood cells with serum from the patient who is to receive the transfusion. If the recipient has antibodies against the donor red blood cells, hemagglutination will occur.
These tests help to ensure the compatibility of blood for transfusions and can be used to detect specific antibodies in a person's blood, thereby revealing the presence and quantity of certain bacteria or viruses. Therefore, they serve as important tools in medicine for accurate diagnosis and successful blood transfusions.

D
Explanation:
Flowing water has intrinsic kinetic energy that is harnessed to rotate the turbine. The turbine rotates hence gains mechanical energy because it is doing work. This work is used to rotate a dynamo of a generator which generates electricity. The mechanical energy is thus converted into electric energy by the dynamo. The electric energy is then carried by the power lines to the users.

Based on the information in the table, which of the following changes is least likely to produce a phenotypic
change in an organism?
A. GAU to GGU
B. GAU to GUU
C. GAU to GAA
D. GAU to GAC
GAU to GAC is least likely to change phenotype of an organism.
Explanation:Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.
Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.
Both the GAU and GAC codes for aspartic acid. So the phenotype won't be affected much by this mutation
Definition: These are the standards that determine a scientists behaviors, right or wrong
Example: Is stem cell research right or wrong?
Answer:
Ethics
Explanation:
Scientific ethics are a set of moral standards that help to define right and wrong, helping to guide decision making when carrying out scientific research.
Sometimes scientific ethics can be highly complicated and there is often no clear "right" and "wrong", which is why guidelines for best practices are extremely important with controversial research topics like stem cell research.
Ethics guides decision making from what research is allowed to be carried out (e.g. animal testing) to reporting of results (e.g. making sure that results are accurate).
Scientific ethics is so important, that there is an entire branch of biology dedicated to it, called bioethics.

what is required for a person to have cickle cell disease
Two genes for the sickle hemoglobin must be inherited from one's parents in order to have the disease.
Answer: Two alleles for mutated haemoglobin is required to have sickle cell disease
Explanation: Sickle cell disease is a genetic disorder in which an individual inherits two allele for sickled haemoglobin from the parents. Every trait is controlled by a pair of gene, one gene from each parent. For an individual to have sickle cell disease he must have two alleles for the mutated haemoglobin, one from each parent. Haemoglobin is a protein found in the red blood cells that binds and transports oxygen to the cells. Haemoglobin is a protein with four subunits: two alpha chains and two beta chains. In a mutated haemoglobin, valine replaces glutamate at position six of the two beta chains. This point mutation on the beta chains of haemoglobin causes the aggregation of haemoglobin, thus giving the red blood cells a sickle shape instead of a disc shape of normal haemoglobin. The allele for the sickle haemoglobin is represented as S and for an individual to have sickle cell disease, he or she must inherit one allele from each parent.

3. a. Reviewing How does a mutation in a gene
affect the order of DNA bases?
Final answer:
A mutation in a gene alters the DNA sequence, potentially impacting the amino acid sequence of a protein. Substitutions may have minimal or significant effects, while insertions or deletions can lead to frameshift mutations with extensive consequences.
Explanation:
A mutation in a gene can result in changes to the order of DNA bases. Three common types of mutations are substitution, insertion, or deletion. In the case of substitution, one base is replaced by another, which may or may not affect the amino acid sequence, depending on whether the new codon codes for a different amino acid or the same one (due to the redundancy in the genetic code).
An insertion or deletion can have more drastic effects. These mutations can lead to a change in the reading frame, known as a frameshift mutation, potentially altering the entire amino acid sequence downstream of the mutation. For example, consider the sequence 5'-ATGGCAATCCTCAACGCTGT-3'. If an insertion occurs after the start codon AUG, this addition could shift the reading frame and change the way codons are read, thereby changing the amino acids encoded by these codons.
The effect of a mutation on the protein's amino acid sequence depends on its location and type. Using Figure 19.14 "The Genetic Code" as a reference, one can predict the specific consequences for the protein sequence. In the example of a substitution from AUU to AUC, this would be a silent mutation since both codons code for the amino acid Isoleucine. However, if the mutation results in a codon for a different amino acid or a stop codon, it could lead to a missense or nonsense mutation, respectively, dramatically impacting the protein structure and function.
1. When the temperatures of materials that are in contact are
the same, the materials are said to be in thermal convection,
to without passing
Answer:
themometer
Explanation:
Final answer:
Thermal contact occurs when two objects are close enough to permit heat transfer. Conduction is the transfer of heat through a material without the material itself moving. This continues until thermal equilibrium is reached, where no heat flows between the objects in contact.
Explanation:
When talking about materials in contact and their temperatures, we refer to the concept of thermal contact. This occurs when two objects are in such close proximity that heat transfer can occur between them. An important principle related to thermal contact is thermal equilibrium, which is the condition where objects in thermal contact no longer exchange heat, as they have reached the same temperature.
Heat transfer can take place in different ways, one of which is conduction. Conduction is the transfer of heat through a stationary material, without the movement of the material itself. The material through which heat is being transferred is known as a thermal conductor. Heat will naturally flow from the hotter object to the cooler one until thermal equilibrium is reached.
An example of conduction is when heat is transferred from the electric burner of a stove to the bottom of a pan despite there being no movement of the material of the pan; the motion of atoms and molecules at the microscopic level facilitates this heat transfer.
What happens after an atom stores energy from passing electrons?
Answer: the electrons lose some or all of the excess energy by emitting light.
Explanation: These levels are called energy states. ... When an electron in an atom has absorbed energy it is said to be in an excited state. An excited atom is unstable and tends to rearrange itself to return to its lowest energy state. When this happens, the electrons lose some or all of the excess energy by emitting light.
please give brainliest!
Answer: the electrons lose some or all of the excess energy by emitting light.
Explanation: When an electron is hit by a photon of light, it absorbs the quanta of energy the ... Electrons therefore have to jump around within the atom as they either gain or lose ...

to which two molecules does transfer RNA attach
Answer: messenger RNA and amino acids.
Explanation: A transfer RNA (tRNA) is a type of RNA whose function is to fetch and match the corresponding amino acid to the codon on the mRNA during translation. A tRNA has a three nucleotide sequence known as anticodon through which it attaches to the codon on the mRNA molecule. During translation, the codons on the mRNA molecule is read one after another by the ribosome while the tRNA attaches itself to the mRNA codon that is being read through its anticodon. The tRNA then fetches the corresponding amino acid from the cytosol and attaches it to the growing polypeptide chain.
Transfer RNA (tRNA) attaches to two specific molecules, amino acids, and messenger RNA (mRNA), during protein synthesis. Aminoacyl tRNA synthetases link the amino acid to tRNA, and the tRNA's anticodon binds to the mRNA's codon to correctly position the amino acid for incorporation into the protein.
Explanation:Transfer RNA, or tRNA, is crucial for the synthesis of proteins. The two specific molecules that tRNA attaches to are amino acids and messenger RNA (mRNA). The tRNA picks up free amino acids in the cytosol and transfers them to the ribosome, where protein synthesis occurs. At the ribosome, the tRNA recognizes specific three-nucleotide sequences called codons on the mRNA through its anticodon. The anticodon-codon interaction allows for the amino acid to be correctly added to the growing polypeptide chain.
tRNA molecules interact with various factors during this process, including aminoacyl tRNA synthetases, which attach the correct amino acid to the tRNA, and the ribosome itself, which facilitates the assembly of the amino acids into a protein. There are numerous types of tRNA, each corresponding to one or more codons that specify a particular amino acid.

Without the process of transpiration, what might happen to a plant?
It might turn orange.
It would grow more slowly.
It would have fewer leaves.
It might burst.
Answer:
Without the process of transpiration, plant might turn orange. It is because of wilting occur in plants. Transpiration is very important for plants growth and survival. Transpiration helps in the uptake of water from the soil. This water is used in the process of photosynthesis. Without this water, the plant wilts due to the removal of water from plant body and plant die. So transpiration is very important for plants.
