Answer:
Wavelength and Frequency
Explanation:
The speed of a wave can be related to the speed of an object which is calculated using:
[tex]Speed = \frac{Distance}{Time}[/tex]
So: the speed of a wave (v) is calculated using:
[tex]v = f * L[/tex]
Where:
[tex]f= Frequency[/tex]
[tex]L = Wavelength[/tex]
Frequency is calculated as:
[tex]f = \frac{1}{T}[/tex]
Where:
[tex]T = Period[/tex]
This means that the two basic information needed are the wavelength and the frequency of the wave
what kind of authority does our elected government officials exercise?
Answer:
Depending upon the country and community in which you live, the authority exercised by elected officials is defined by formal rules and informal norms of behavior that apply in that jurisdiction. Authority is the willing compliance, almost automatic, with dictates from figures to whom we grant that authority. The formal rules limiting government officials’ authority should protect citizens from abuses of that authority but informal norms may sometimes allow elected officials to get away with actions that violate those rules or, at least, bend them to their own purposes.
Rational- legal authority is practiced by elected government officials. The
practice of the people voting the officials they deem fit is referred to as
Democracy.
Democracy involves leadership of the people through laws which govern
that area. The laws are referred to as constitution and contains the power
and authority that government officials and says what can be done by them
or not with laid down consequences if disobeyed.
This however helps to put office holders in check as no one is above the
law in order to prevent anarchy.

Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. So I believe the answer you are looking for would be the third one :)

If i added 27 grams of salt to water and saparated the solution with a hot plate what amount of salt will be left behind
Answer:
27 grams
Explanation:
27 grams of salt would still be left behind.
The dissolution of salt in water is a physical reaction and the salt can be recovered by evaporating off the water using appropriate procedures.
Provided that no part of the salt/water mixture is lost during the process of evaporation, if 27 grams of salt was dissolved initially, the same amount of salt would be recovered at the end of the separation process.
A scientist with the EPA examining water for contamination writes down that there was an iridescent sheen on the surface of the water. What type of data did the scientist record
Answer: Qualitative data
Explanation:
Since we are informed that the scientist writes down that there was an iridescent sheen on the surface of the water, this is a qualitative data.
Qualitative data is a firm of data that one can observe and then record. It should also be noted that it is non numerical. It can be gotten from observations, conducting focus groups, having a one-to-one interviews, etc.
Answer: this is qualitative and categorical (binary) data
Explanation:
There are no measurements. The observation is qualitative: observation of some change in appearance. It is categorical in that the possible values are only ‘no sheen’ or ’sheen’.

investigate the conditions required for seed to germinate. keep the dishes at room temperature for a week.explain your observations
Dry cotton wool
wet cotton wool
covered with water
Explanation:
Starting off, the conditions required for a seed to germinate are:
warm temperatures, so that enzymes can act efficiently.water, for chemical reactions to place.oxygen, for respiration.Observations:
Dry cotton wool: Seeds placed here will not germinate. They will not show any changes since not all the the conditions are met. (There's no water)
Wet cotton wool: Seeds placed here will germinate since all the conditions required for germinations to take place are met.
Covered with water: The seeds will gradually start to expand. The oxygen which is dissolved in water does not enter the seed due to excess water thus preventing germination.

Identify and describe the three ways the mutations affect organisms
Answer:
they may cause the development of a disease-causing allele
they may cause the development of a more beneficial allele
they, in some cases, may have no noticeable affect.
Explanation:
Answer:
Mutations may be beneficial, harmful, or neutral to organisms. If the change caused by a mutation is useful to the organism, then it is beneficial. If the change is damaging to an organism, then it is harmful. If the change is neither useful nor damaging, then the mutation is neutral.
