Answer:
When a wave becomes too high relative to the depth of the water, it can no longer support its own weight and topples to the shore, resulting in a breaker. Waves Even though it looks as though waves are moving forward, in reality only a relatively small amount of water is displaced, and what you actually see is a transfer of energy..
Answer:
4. Water waves meet the shore and cause the crest to spill over the trough.
Explanation:
A breaker is a wave that has the crest spill over toward the trough as it approaches shore.

Which two characteristics do polar and dry climates have in common?
high altitude and very cold winters
very cold winters and contrasting seasons
contrasting seasons and very little precipitation
very little precipitation and few, specialized plants
Answer:
D. very little precipitation and few, specialized plants
Explanation:
its the answer on edge
The two characteristics which polar and dry climates have in common include very little precipitation and few specialized plants. Thus, the correct option is D.
What are Polar and Dry climates?A polar climate is a place where the climate generally has a temperature below the freezing, icy, and it is covered in snow. These areas do not get enough amount of direct heat and sunlight from the sun. Polar climates are located at the North Pole of the Arctic, and at the South Pole on the continent of Antarctica.
The dry climate are found in deserts which are very dry and the temperature of these areas are very high.
Both of these climates show some common characteristics such as very little precipitation and few specialized plants which can survive in these conditions.
Therefore, the correct option is D.

Explanation:
There are some specific ethical guidelines and standards for the forensic scientists to follow. But it was not always so. Investigate how the standards and ethics code came to be established over the years. Also, discuss whether they have helped as much as they should have.
Answer:
Explanation:
The field of forensic science is important to the criminal justice system. Forensic personnel must pay close attention to detail during the collection, preservation, and analysis of physical evidence. If evidence is mishandled, manipulated, or misinterpreted it can potentially destroy a case and/or the lives of all individuals involved
Answer:
Explanation:
In 1904, Scotland Yard officials introduced fingerprint matching to US law enforcement officials at the World’s Fair. The fact that forensic science was not born from the scientific community meant that forensic scientists were not always bound to the quest for knowledge, but instead for the purpose of solving crimes. This difference led to misaligned incentives. Expert witnesses were often paid per conviction in many states.
In the late 1980s, DNA evidence, which was born in the scientific community, has helped identify the guilty and exonerate the innocent. Many other forensic techniques, such as hair microscopy, ballistics analysis, and arson investigations, have not been subjected to the rigorous scientific evaluation that DNA analysis has. Other techniques, such as blood typing, have been properly validated.
These invalidated techniques have led to the Innocence Project, which holds that forensic science techniques should be shown to be valid and reliable through research and assessment of validity and reliability, and subject to accreditation and certification to assure quality. States are eligible to receive grant money if they do so. This change has resulted in the growth of many organizations, such as the ASCLD/LAB, that accredit forensic scientists.

the growth of plants due to gravity
Answer:
Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it. Gravity can be either "artificial gravity" or natural gravity. It is a general feature of all higher and many lower plants as well as other organisms.
Explanation:
Sweet yellow tomatoes with a pear shape bring a high price per basket to growers. Pear shape, yellow color, and terminal flower position are recessive traits produced by alleles, f, r, and t, respectively.
The dominant phenotypes for each trait – full shape, red color, and axial flower position – are the product of dominant alleles F, R, and T. A farmer has two pure-breeding tomato lines. One is full, yellow, terminal and the other is pear, red, axial. Design a breeding experiment (crosses) that will produce a line with tomato that is pure-breeding for pear shape, yellow color, and axial flower position.
Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.
The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.
With an individual of F1 crosses with another individual of F1, the Punnet Square will be:
FfRrTt x FfRrTt
1) Dividing each characteristics, for simplicity:
F f
F FF Ff
f Ff ff
R r
R RR Rr
r Rr rr
T t
T TT Tt
t Tt tt
Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.

When an enemy cell is present, a(n) __________ secretes perforins, which bore a hole in the enemy cell membrane.
a. interleukin
b. antibody
c. interferon
d. natural killer cell
e. opsonization
The correct answers is D. Natural killer cell
Explanation:
Natural killer cells are a type of cell in the immune system. These differ from other cells because these are innate, this means they attack all enemy cells or pathogens and are not specific. Also, they are the first general immune defense.
Moreover, the role of these cells to attack any enemy cell including cancer cells is possible due to specific chemicals or substances these cells release. One of these is perforins, which are mainly released by natural killer cells and destroy these by creating lesions in the cell membrane. According to this, the correct answer is D.

Activator or repressor proteins which bind DNA to regulate the transcription of genes do so mainly by: A. Covalent interactions between the protein and specific bases in the major groove of DNA B. Covalent interactions of Zn2 atoms with the phosphodiester backbone C. Non-covalent interactions between the protein and specific bases in the major groove of DNA D. Covalent interactions with nearby nucleosomes E. Answers B and D are correct
Answer:
C. Non-covalent interactions between the protein and specific bases in the major groove of DNA
Explanation:
Activator or repressor proteins are proteins with specific DNA-binding domains that have affinity by one or two DNA strands. In general, these proteins interact with the major groove of the B-DNA structure since this structure exposes more functional groups for binding. Non-covalent interactions are a type of interaction that does not involve the sharing of electrons. The interaction between proteins and DNA is due to the combination of different non-covalent interactions, which can be classified into four major types: van der Waals, hydrophobic, hydrogen and ionic interactions.
How does the formation of NAD+ differ between aerobic and anaerobic respiration?
A. NAD+ is formed in aerobic respiration by a fermentation process and formed in anaerobic respiration by oxidation of NADH.
B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.
C. Under aerobic conditions, the electron acceptor is a molecule other than oxygen for NAD+ production, whereas under anaerobic conditions the electron acceptor is oxygen.
D. NAD+ is formed by the breakdown of pyruvate to form oxaloacetate in anaerobic respiration whereas in aerobic respiration it is formed by the breakdown of pyruvate into lactic acid or alcohol.
Answer:
B. NAD+ is formed by a fermentation process in anaerobic respiration by the conversion of pyruvate into lactate and by simple oxidation of NADH in aerobic respiration.
Explanation:
Nicotinamide adenine dinucleotide (NAD) is an important coenzyme that may exist in two different forms: oxidized (NAD+) and reduced (NADH). The fermentation is an anaerobic oxidation-reduction reaction where pyruvate and NADH are reactants, while lactate and NAD+ are products generated by the oxidation of NADH to NAD+ and pyruvate to lactate, respectively. On the other hand, during aerobic respiration, NADH generated by glycolysis is oxidized to form NAD+ by the donation of its electrons to reduce pyruvate to lactate. Subsequently, NAD+ is reused in glycolysis (again) in order to generate more molecules of ATP.
